[alsa-devel] no sound when using TV-Out
by Reiner 14 Nov '09

Hello, I have something strange: I have had Suse 11.1 (64 bit) and everything was ok. Now I have Suse 11.2 (64 bit) and xine, MPlayer are playing fine (with audio) if using the already running x-Server. For using the TV-OUT I have a seperate section in xorg.conf and I start a new X server with this conf, chnage the DISPLAY variable and launch xine, Mplayer. This has worked! Now I get a picture but no sound with BOTH players (xine, mplayer).So I think it has to do with some access rights to the sound device. PS: Pulse audio is not installed (with it flash has no sound) Any ideas ? Thanks Reiner

[alsa-devel] [RFC][PATCH] ARM: OMAP: McBSP: Use register cache
by Janusz Krzysztofik 14 Nov '09

14 Nov '09

Change the way McBSP registers are updated: use cached values instead of relying upon those read back from the device. With this patch, I have finally managed to get rid of all random playback/recording hangups on my OMAP1510 based Amstrad Delta (buggy?) hardware. Before that, I could suspect that values read back from McBSP registers before updating them happened to be errornous. I think there is one important point that makes this patch worth of applying, apart from my hardware quality. With the current code, if it ever happens to any machine, no matter if OMAP1510 or newer, to read incorrect value from a McBSP register, this wrong value will get written back without any checking. That can lead to hardware damage if, for example, an input pin is turned into output as a result.

[alsa-devel] alsa-info: problem hda-intel based card
by Halim Sahin 12 Nov '09

12 Nov '09

Hello, I.ll attach an output of alsa-info.sh. The mainboard is a pov 330 (nvidia ion). The soundcard has three connectors 1. output 2. mic 3. line there are also a sp/dif and a hdmi device I have two problems: 1. The outputvolume of front is really low. Alsamixer shows front and surround but the later one has no effect. 2. hdmi output isn't active in the alsa default output. I can specify hw0,3 which works but it disables dmix. So the problem is how to enable hdmi audio out this way that aplay -Ddefault can use all available outputs simultaniously (analog, sp/dif, and hdmi). Thanks in advance for any help. BR.

[alsa-devel] [PATCH] ASoC: Add jack_status_check callback function
by Joonyoung Shim 12 Nov '09

12 Nov '09

The jack_status_check callback function is the interface to check the status of the jack. Some target provides the method to distinguish what is the jack inserted - headphone jack, microphone jack, tvout jack, etc, so we can implement it using the jack_status_check function.

[alsa-devel] [PATCH v2] soc-core: move setting ac97 platformdata earlier than ac97 read/write
by Barry Song 12 Nov '09

12 Nov '09

While probing, AC97 codec drivers and soc-core generically execute the following sequence: snd_soc_new_ac97_codec -> snd_soc_new_pcms -> reset ac-link/read AC97 ID to detect ->... -> set platform_data to ac97 by soc-core commit 474828a40f6ddab6e2a3475a19c5c84aa3ec7d60 adds platform_data to snd_ac97 instance. But ac97 platform data hasn't given to snd_ac97 before actual ac97 operations. Then while ac97_read access platform_data of snd_ac97 for detecting, NULL pointer oops will fire. That means old platform_data patch doesn't work in real-life cases. This patch moves the operation of setting ac97 platform_data earlier than ac97 reading/writing operations. Then it makes platform_data of AC97 become practically useful.

[alsa-devel] [PATCH 0/6] Fixups to MPC5200 ASoC drivers
by Grant Likely 12 Nov '09

12 Nov '09

Hi everyone, Jon, as we talked about earlier today, I've spent some time working on the MPC5200 AC97 driver to try and get rid of some of the nagging bugs. The two big changes that I ended up making were to remove the tracking of appl_ptr (and all the race conditions that went with it), and to fix the handling of AC97 slot enables/disables so that a stream can be stopped and started again without going through the hw_params() step. I know that you had the appl_ptr tracking in to try and solve the problem of audible noise at the end of playback. After discussing the data flow model on #alsa-soc this morning, I learned that the driver is really supposed to be free-running, and the ALSA layer is supposed to be able to keep up. It is also responsible to ensure that buffer is filled with silence at the end of playback to eliminate noise before the trigger can properly turn everything off. Only a couple of other drivers use appl_ptr, so I'm pretty sure this driver shouldn't be doing it either. Instead, from a recommendation this morning, I added a 'fudge' factor to the value reported by the .pointer() callback of 1/4 the period size. At first I thought this helped, but after more testing I find that the driver seems to work correctly with aplay both with and without the fudge factor applied. However, I was able to reproduce the noise problem when using aplay if I have DEBUG #defined at the top of the mpc5200_dma.c file with debug console logs being spit out the serial port. In that situation, the STOP trigger calls printk(), and a stale sample can be heard at the end of playback. However, I believe this is a bug with the serial console driver (in that it disables IRQs for a long time) causing unbounded latencies, so the trigger doesn't get processed fast enough. It doesn't help that aplay doesn't flush the buffers with silence before triggering STOP. Other programs (like gstreamer) do seem to flush out stale data before stopping the stream. I'm sure someone will correct me if I'm making some bad assumptions here. So, please test. Let me know if these work or not. I've don't know if the last patch (Add fudge factor...) is needed or not. Cheers, g. --- Grant Likely (6): ASoC/mpc5200: Add fudge factor to value reported by .pointer() ASoC/mpc5200: fix enable/disable of AC97 slots ASoC/mpc5200: add to_psc_dma_stream() helper ASoC/mpc5200: Improve printk debug output for trigger ASoC/mpc5200: get rid of the appl_ptr tracking nonsense ASoC/mpc5200: Track DMA position by period number instead of bytes sound/soc/fsl/mpc5200_dma.c | 98 ++++++++++---------------------------- sound/soc/fsl/mpc5200_dma.h | 24 ++++++--- sound/soc/fsl/mpc5200_psc_ac97.c | 39 ++++++++------- 3 files changed, 63 insertions(+), 98 deletions(-) -- Signature

[alsa-devel] [PATCH] add support to reorder CPU and Codec DAI suspend/resume
by Barry Song 12 Nov '09

12 Nov '09

Due to some hardware dependence issues, some devices maybe require different suspend/resume execution order for CPU and Codec DAI to make sure the hardware can work normally after executing sleep and wakeup. In old ALSA driver, people include all suspend/resume operations of both CPU and Codec in same entries. Then they change order according to actual require. But in ASoC, we should give a chance to users to reorder CPU/Codec DAI suspend/resume instead of defining the fixed order if there are some strange hardware dependence problems.

[alsa-devel] [PATCH 13/13] pcmcia: rework the irq_req_t typedef
by Dominik Brodowski 11 Nov '09

11 Nov '09

Most of the irq_req_t typedef'd struct can be re-worked quite easily: (1) IRQInfo2 was unused in any case, so drop it. (2) IRQInfo1 was used write-only, so drop it. (3) Instance (private data to be passed to the IRQ handler): Most PCMCIA drivers using pcmcia_request_irq() to actually register an IRQ handler set the "dev_id" to the same pointer as the "priv" pointer in struct pcmcia_device. Modify the two exceptions (ipwireless, ibmtr_cs) to also work this waym and set the IRQ handler's "dev_id" to p_dev->priv unconditionally. (4) Handler is to be of type irq_handler_t. (5) Handler != NULL already tells whether an IRQ handler is present. Therefore, we do not need the IRQ_HANDLER_PRESENT flag in irq_req_t.Attributes.

[alsa-devel] [PATCH] ALSA: hda_intel: disable corb rirb when single_cmd active
by Troy Kisky 11 Nov '09

[alsa-devel] What is a name for the PC speaker input/output volume control?
by Krzysztof Helt 11 Nov '09

11 Nov '09

Hi Takashi, I have run into the issue that OSS emulation layer provides less controls than the alsa mixer. One specific problem is the OSS Speaker control is not properly mapped on all drivers (among others the wss/cs4236 family) due to the fact that the speaker input/output is called "Mono" in this driver. I have found that there are at least three names are used by drivers: "PC Speaker" "Speaker" "Mono" for the same input/output pair (At least on the ISA cards there is only single purpose mono channel - to route the PC speaker). Which name should be used? I will convert all ISA drivers to the selected name (and fix the OSS mixer to map this name to the "Speaker" control).

[alsa-devel] [PATCH] soc-core: move setting ac97 platform data earlier than ac97 read/write
by Barry Song 11 Nov '09

11 Nov '09

While probing, AC97 codec drivers generically execute the following sequence: snd_soc_new_ac97_codec -> snd_soc_new_pcms -> reset ac-link/read AC97 ID to detect ->... -> snd_soc_init_card commit 474828a40f6ddab6e2a3475a19c5c84aa3ec7d60 adds platform_data to snd_ac97 instance. But ac97 platform data hasn't given to snd_ac97 until snd_soc_init_card. Then while ac97_read access platform_data of snd_ac97 for detecting, NULL pointer oops will fire. That means old platform_data patch doesn't work in real-life cases. This patch moves the operation of setting ac97 platform_data earlier than ac97 reading/writing operations. Then it makes platform_data of AC97 become practically useful.

What does the hardware look like and what is the problem you're trying to solve here? Sending stream events into the core is a definite layering violation and is likely to fail with some use case transitions but without knowing what the patch is trying to achieve it's hard to offer much advice. > +static const char *path_control[] = {"Off", "On"}; > +static const struct soc_enum zoom2_enum[] = { > + SOC_ENUM_SINGLE_EXT(ARRAY_SIZE(path_control), path_control), > +}; Why is this an enumerated control and not a switch?

[alsa-devel] [PATCH 1/7] S3C AUDIO: Rename s3c24xx_pcm prefix to s3c_dma
by Jassi Brar 11 Nov '09

11 Nov '09

The s3c24xx_pcm prefix for the soc_platform is inappropriate when some Samsung SoCs have PCM controllers which will eventually have drivers and hence namespace ambiguities. To resolve naming ambiguities in future the following have been renamed in order 1) s3c24xx_pcm_dma_params -> s3c_dma_params 2) s3c24xx_pcm_preallocate_dma_buffer -> s3c_preallocate_dma_buffer 3) s3c24xx_pcm_dmamask -> s3c_dma_mask 4) s3c24xx_pcm_XXX -> s3c_dma_XXX Signed-off-by: Jassi Brar <jassi.brar(a)samsung.com> --- sound/soc/s3c24xx/s3c-i2s-v2.c | 2 +- sound/soc/s3c24xx/s3c-i2s-v2.h | 4 +- sound/soc/s3c24xx/s3c2412-i2s.c | 4 +- sound/soc/s3c24xx/s3c2443-ac97.c | 10 ++-- sound/soc/s3c24xx/s3c24xx-i2s.c | 10 ++-- sound/soc/s3c24xx/s3c24xx-pcm.c | 76 +++++++++++++++++++------------------- sound/soc/s3c24xx/s3c24xx-pcm.h | 6 +- sound/soc/s3c24xx/s3c64xx-i2s.c | 4 +- 8 files changed, 58 insertions(+), 58 deletions(-) diff --git a/sound/soc/s3c24xx/s3c-i2s-v2.c b/sound/soc/s3c24xx/s3c-i2s-v2.c index 28b0ab2..5a442aa 100644 --- a/sound/soc/s3c24xx/s3c-i2s-v2.c +++ b/sound/soc/s3c24xx/s3c-i2s-v2.c @@ -394,7 +394,7 @@ static int s3c2412_i2s_trigger(struct snd_pcm_substream *substream, int cmd, int capture = (substream->stream == SNDRV_PCM_STREAM_CAPTURE);

[alsa-devel] hda-intel: no codecs initialized with Teradici sound card and ALSA 1.0.17
by James Pearson 10 Nov '09

10 Nov '09

I'm using CentOS 5.3 (which uses ALSA 1.0.17) and a Teradici KVM over IP extender - which has an hda_intel type sound chipset However, when the snd_hda_intel module is loaded, dmesg reports: PCI: Enabling device 0000:04:00.1 (0000 -> 0002) ACPI: PCI Interrupt 0000:04:00.1[A] -> GSI 16 (level, low) -> IRQ 177 PCI: Setting latency timer of device 0000:04:00.1 to 64 hda-intel: no codecs initialized ACPI: PCI interrupt for device 0000:04:00.1 disabled ... and /proc/asound/cards reports: --- no soundcards --- I've tried loading the snd-hda-intel module with various 'model=' options (including basic and auto), but it makes no difference However, we also have CentOS 4.7 on machines with same Teradici card using ALSA 1.0.15 (that replaces the ALSA version that ships with CentOS 4) patched to support the Teradici card - using a patch based on the one that went into ALSA 1.0.17 to support the Teradici card. In this case the audio works - dmesg reports: ACPI: PCI Interrupt 0000:82:00.1[A] -> GSI 47 (level, high) -> IRQ 233 PCI: Setting latency timer of device 0000:82:00.1 to 64 hda_codec: Unknown model for ALC883, trying auto-probe from BIOS... And in this case, /proc/asound/cards reports: 0 [Teradici ]: HDA-Intel - HDA Teradici HDA Teradici at 0xd0100000 irq 233 and playback works fine. Any idea why ALSA 1.0.17 doesn't work with the Teradici card? I don't really want to replace the the ALSA kernel code with a more up to date version if at all possible ... is there a way of 'forcing' the 1.0.17 code 'to work' ? lspci -vv for this card reports 04:00.1 Audio device: Teradici Corp.

[alsa-devel] [PATCH 0/4 v2] ASoC/MFD/OMAP: TWL4030: APLL_CTL handling change
by Peter Ujfalusi 10 Nov '09

10 Nov '09

Hello, Changes from the first series: - Typos fixed and warning/error messages for APLL frequency mismatch now consistent - twl4030-codec MFD driver audio_mclk validity check simplified - Commit message for the twl4030-codec MFD driver has been changed also - Patch: "ASoC: TWL4030: Make sure, that the codec is powered on startup" has been removed from the series, since it is already taken. Intro text from the first series: The following series changes the way how the APLL_CTL register is handled by the twl4030 codec related drivers. Moving the configuration of APLL_CTL register from child drivers (specifically from soc codec driver) to the twl4030-codec MFD driver. Because the audio_mclk is static, board specific and can not be changed in runtime, the codec MFD is the right place to configure it early enough, so child can use the hardware correctly. Before this patch for example the APLL_INFREQ was configured first, when the user played or recorded audio via the twl4030. The digital bypass needs correct APLL_INFREQ to be configured in order to work properly. If the digital bypass enabled before any audio activity, in some cases the bypassed audio was not correct. The series also addresses the issue, that after boot-up, neither of the loopbacks was working, because the codec was actually off. Setting the codec->bias_level to _OFF, before setting the codec bias level to STANDBY fixes this issue. This series is on top of Takashi's sound-2.6 topic/asoc branch, which has the twl403-codec MFD and related patches for 2.6.33. It would be really nice, if this series would make it also to the same branch, since this fixes some real anomalies brought in by the cleanup of the twl4030 codec related drivers. These problems were hidden before because of the inconsistent handling of bits and states in the codec driver in the past. --- Peter Ujfalusi (4): MFD: TWL4030: Add audio_mclk to the codec platform data OMAP: Configure audio_mclk for twl4030-codec MFD MFD: twl4030-codec: APLL_INFREQ handling in the MFD driver ASoC: TWL4030: Do not modify the APLL_CTL register arch/arm/mach-omap2/board-3430sdp.c | 1 + arch/arm/mach-omap2/board-omap3beagle.c | 1 + arch/arm/mach-omap2/board-omap3evm.c | 1 + arch/arm/mach-omap2/board-omap3pandora.c | 1 + arch/arm/mach-omap2/board-overo.c | 1 + arch/arm/mach-omap2/board-zoom2.c | 1 + drivers/mfd/twl4030-codec.c | 35 ++++++++++++++ include/linux/i2c/twl4030.h | 1 + include/linux/mfd/twl4030-codec.h | 1 + sound/soc/codecs/twl4030.c | 76 ++++++++++++------------------ 10 files changed, 74 insertions(+), 45 deletions(-)

Flo, Why do you say "No. This is a pro audio card and it's full potential cannot be used with ALSA."? What is there in Alsa that will restrict the use of the card (or any card) for pro audio use? The Trinnov room correction system which is a pro market product uses Hammerfall cards and Alsa to do some very ambitious pro audio functions for example.

[alsa-devel] Crackly sound with dmix rate 48000
by Daniel Drake 10 Nov '09

10 Nov '09

Hi, In our musical activities, the OLPC/Sugar platform uses csound which in turn uses ALSA for playing sounds. On our latest XO hardware model, where we now use HDA instead of cs5536, we are experiencing some crackly sounds from our csound-based applications. Other apps are fine. We discovered that changing the dmix rate from 48000 to 44100 solves the cracklyness. What does this indicate? Might csound be producing sounds at rate 44100, which dmix previously had to convert to 48000, which was too taxing to the system? Any suggestions for how to diagnose this further? (or would changing the rate be seen as a reasonable thing to do in this situation?) Thanks, Daniel

[alsa-devel] [PATCH] ALSA: hda - Tweak OLPC XO-1.5 microphone bias
by Daniel Drake 10 Nov '09

10 Nov '09

Our contacts at Conexant suggested that we reduce the external microphone bias to 50% in order to center the input signal with the DC input range of the codec. This is because the microphone port is DC coupled for potential use with sensors.

To resolve naming ambiguities in future the following have been renamed in order 1) s3c24xx_pcm_dma_params -> s3c_audio_dma_params 2) s3c24xx_pcm_preallocate_dma_buffer -> s3c_preallocate_dma_buffer 3) s3c24xx_pcm_dmamask -> s3c_dmamask 4) s3c24xx_pcm_XXX -> s3c_dma_XXX Signed-off-by: Jassi Brar <jassi.brar(a)samsung.com> --- sound/soc/s3c24xx/s3c-i2s-v2.c | 2 +- sound/soc/s3c24xx/s3c-i2s-v2.h | 4 +- sound/soc/s3c24xx/s3c2412-i2s.c | 4 +- sound/soc/s3c24xx/s3c2443-ac97.c | 10 ++-- sound/soc/s3c24xx/s3c24xx-i2s.c | 10 ++-- sound/soc/s3c24xx/s3c24xx-pcm.c | 76 +++++++++++++++++++------------------- sound/soc/s3c24xx/s3c24xx-pcm.h | 6 +- sound/soc/s3c24xx/s3c64xx-i2s.c | 4 +- 8 files changed, 58 insertions(+), 58 deletions(-) diff --git a/sound/soc/s3c24xx/s3c-i2s-v2.c b/sound/soc/s3c24xx/s3c-i2s-v2.c index 28b0ab2..9788e65 100644 --- a/sound/soc/s3c24xx/s3c-i2s-v2.c +++ b/sound/soc/s3c24xx/s3c-i2s-v2.c @@ -394,7 +394,7 @@ static int s3c2412_i2s_trigger(struct snd_pcm_substream *substream, int cmd, int capture = (substream->stream == SNDRV_PCM_STREAM_CAPTURE);

[alsa-devel] [PATCH V2] ASoC - Add support for upto 16 channels on OMAP MCBSP
by Liam Girdwood 09 Nov '09

09 Nov '09

[alsa-devel] [PATCH v4 00/12] introduce skip_spaces(), reducing code size plus some clean-ups
by André Goddard Rosa 08 Nov '09

08 Nov '09

This patch reduces lib.a code size by 173 bytes on my Core 2 with gcc 4.4.1 even considering that it exports a newly defined function skip_spaces() to drivers: text data bss dec hex filename 64867 840 592 66299 102fb (TOTALS-lib.a-before) 64954 584 588 66126 1024e (TOTALS-lib.a-after) and implements some code tidy up. Besides reducing lib.a size, it converts many in-tree drivers to use the newly defined function, which makes another small reduction on kernel size overall when those drivers are used. p.s.: Ingo, I hope to have finally fixed my environment by using send-email now. Please let me know if you have any problem with these and thank you for the good advice. get_maintainer.pl gave lots of people as output, I hope that's ok. Changelog: v4: convert drivers over newly defined skip_spaces() function v3: improved comments on patch 5/7 and factorize a switch statement on 6/7 as per suggestions from Ingo and Frederic (thanks!) v2: addressed feedback from Frederic Weisbecker review (thanks!!) and split into separate patches v1: original submission André Goddard Rosa (12): vsprintf: factorize "(null)" string vsprintf: pre-calculate final string length for later use vsprintf: give it some care to please checkpatch.pl vsprintf: use TOLOWER whenever possible vsprintf: reduce code size by avoiding extra check vsprintf: move local vars to block local vars and remove unneeded ones vsprintf: factor out skip_space code in a separate function vsprintf: reuse almost identical simple_strtoulX() functions ctype: constify read-only _ctype string string: factorize skip_spaces and export it to be generally available string: on strstrip(), first remove leading spaces before running over str tree-wide: convert open calls to remove spaces to skip_spaces() lib function arch/s390/kernel/debug.c | 3 +- arch/um/drivers/mconsole_kern.c | 16 +- arch/x86/kernel/cpu/mtrr/if.c | 11 +- drivers/md/dm-table.c | 6 +- drivers/md/md.c | 4 +- drivers/parisc/pdc_stable.c | 9 +- drivers/platform/x86/thinkpad_acpi.c | 7 +- drivers/pnp/interface.c | 36 +--- drivers/s390/block/dasd_proc.c | 5 +- drivers/video/backlight/lcd.c | 4 +- drivers/video/display/display-sysfs.c | 2 +- fs/cachefiles/daemon.c | 8 +- fs/ext4/super.c | 7 +- include/linux/ctype.h | 2 +- include/linux/string.h | 1 + kernel/params.c | 8 +- lib/argv_split.c | 13 +- lib/ctype.c | 50 +++--- lib/dynamic_debug.c | 4 +- lib/string.c | 19 ++- lib/vsprintf.c | 342 ++++++++++++++++----------------- net/irda/irnet/irnet.h | 1 + net/irda/irnet/irnet_ppp.c | 8 +- net/netfilter/xt_recent.c | 3 +- sound/pci/hda/hda_hwdep.c | 7 +- 25 files changed, 264 insertions(+), 312 deletions(-)

[alsa-devel] RME HDSPe AIO
by Jonathan Leonard 08 Nov '09

08 Nov '09

Hello, I am writing in regards to the RME HDSPe AIO card and its support in ALSA. The card itself in 64studio is recognized incorrectly as HDSP MADI rev d4. Running lspci -nn shows this line for the device: 02:00.0 Multimedia audio controller [0401]: Xilinx Corporation RME Hammerfall DSP MADI [10ee:3fc6] (rev d4) ALSA in 64studio 3.0 beta 3 loads snd-hdspm incorrectly when it should be loading snd-hdsp. I have reviewed pcitables and pci.ids on this distro, and also the public pci reference and the above device id is currently assigned to: Multimedia audio controller: Xilinx Corporation RME Hammerfall DSP MADI (rev d4) The AIO is purported to be very similar to the 9632 and should be using the snd-hdsp module. I would like to use this card in ALSA, and have begun reviewing the guide for making ALSA drivers, but am not sure how exactly to fix the matter since the manufacturer has not incremented the id, or they have not assigned the same id as a 9632. This device is recognized and functioning perfectly on the XP partition. Besides my individual circumstance I wonder if ALSA should not be accomodating this great card somehow. Let me know if I can help by contacting RME developers for info or otherwise. Thank you, jonathan adams leonard

The infoframe would be different for 2-channel pure music and 5.1 channel movie.

I guess the infoframe itself should be identical for the same clip. Have you tried upgrading to a recent Xorg/intel gfx driver? Anyway, the kernel driver code is linux/sound/pci/hda/patch_intelhdmi.c The relevant function is hdmi_setup_audio_infoframe(). Inside which the hdmi_setup_channel_mapping() is not functioning for G45, hdmi_setup_channel_allocation() is no-op for 2-channel music. hdmi_debug_dip_size() and hdmi_clear_dip_buffers() can also be commented out. And feel free to ask more questions :) Thanks, Fengguang

[alsa-devel] [PATCH] es18xx: code improvements
by Krzysztof Helt 08 Nov '09

08 Nov '09

From: Krzysztof Helt <krzysztof.h1(a)wp.pl> 1. Set the third argument of the snd_device_new to not NULL, so there is no warning about bug during chip detection. The third argument is not used in this driver. It was changed in my previous patch. 2. Remove the fm_port and mpu_port fields from the snd_es18xx structure. They can be converted to function arguments. 3. Remove the dmaN_size fields from the snd_es18xx structure. These values are used only in pointer functions and can be easily calculated. 4. Remove the ctrl_lock spinlock which is used only in one read function which is called once during chip initialization. There are many writes to the same register and they are not protected on purpose (see the comment ina the snd_es18xx_config_write()). 5. Use the first part of the text5Sources string table as the text4Soruces table (they are the same). 6. Merge the same cases for the ES1887 and ES1888 when setting chip's caps. 7. Move the snd_es18xx_reset() to __devinit section.

[alsa-devel] (SCH Poulsbo) HD Audio Controller
by Victor Stinner 07 Nov '09

07 Nov '09

Hi, I bought a new Eee PC 1101HA. It uses the "Intel System Controller Hub (SCH) US15W" chipset which includes the "ALC269" (Intel "HD" audio chipset). The pci identifier of the audio sound card is 8086:811b. On Fedora, the snd-hda-intel kernel (from ALSA 1.0.20) module is loaded, but i don't hear anything. On IRC (#alsa on Freenode), gnubien gave me the trick to make it working: write the following configuration in /etc/modprobe.d/alsa.conf file: options snd-hda-intel model=eeepc-p901 Without the model trick, my playback controls are: - Master - Headphone - PCM - Front - Front Mic - Front Mic Boost - Beep With model=eeepc-p901, playback controls are: - LineOut - Mic Boost - Beep - iSpeaker Thanks to model=eeepc-p901, the sound works correctly. Here is the output of alsa-info.sh script: http://www.alsa-project.org/db/?f=3ae0754e841558e9b88a51ceebd5e7a491639750 PS: Please "CC" me to your anwsers. Victor Stinner

[alsa-devel] [SoC] DMA not generate interrupt !
by hung nguyen 06 Nov '09

06 Nov '09

Hi I am writing my audio driver for my board: TMPA910 CPU and WM8960 codec. when I run pcm_min.c, there is an error: "Input/Output error". I find that error because no DMA interrupt appear, printk() in DMA interrupt program no appear I have already set bit IE and ITC in DMA Configuaration register but no change. Here is my source code. Any idea, what could be the reason ?

[alsa-devel] OMAP-McBSP driver not allowing suspend/resume
by Aggarwal, Anuj 06 Nov '09

06 Nov '09

Hi, I am trying to put OMAP3 in suspend state, while audio is playing, by issuing: echo mem > /sys/power/state root@omap3evm:~# echo mem > /sys/power/state PM: Syncing filesystems ... done. Freezing user space processes ... (elapsed 0.00 seconds) done. Freezing remaining freezable tasks ... (elapsed 0.00 seconds) done. Suspending console(s) (use no_console_suspend to debug) Powerdomain (core_pwrdm) didn't enter target state 1 Powerdomain (per_pwrdm) didn't enter target state 1 Could not enter target state in pm_suspend Restarting tasks ... Suspended. Trying resume. done. Done. root@omap3evm:~# As can be seen from the log, both the CORE and PER power domains are not going to the suspend state. On further debug, I found that McBSP 2 instance belongs to the PER domain whereas SDMA belongs to CORE domain. And at least McBSP driver (on l-o tip) doesn't allow disabling of the clocks unless McBSP instance itself is freed. Because of this, when McBSP is stopped after receiving the suspend request, the clocks are still ON and the PER domain is not allowed to enter to the desired low-power state. The McBSP driver needs to be modified so that it can accommodate suspend/resume requests and turns off the clocks when not required. Has anyone modified the driver for this, on some other branch? I tried finding it but could not do so. (Just wanted to make sure before doing the changes) Regards, Anuj Aggarwal

[alsa-devel] Artifacts present in AIC23 capture for 48 KHz sampling rate
by Aggarwal, Anuj 06 Nov '09

06 Nov '09

Hi, I am observing artifacts (sharp spikes at fixed intervals) while capturing audio on AM3517 EVM and AIC23 codec. They are present only in one of the channels when I am capturing at 48 KHz. All other sampling rates are working fine with the above said combination. I have also attached the screenshot taken with the help of Audacity utility. Here, I tried recording silence but artifacts were observed on one channel. Has anyone also observed the similar behavior with AIC23 codec? Any hints on what could be the root cause? Regards, Anuj Aggarwal

[alsa-devel] ALSA full-duplex questions
by pl bossart 06 Nov '09

06 Nov '09

Hi, I have a very low-latency full-duplex application where I would like up- and downlink to be synchronous, i.e. period events happen at the same time for capture and playback. This would minimize the number of wake-ups and enable the platform to go to low power. I thought snd_pcm_link() would enable this coupling between capture and playback, but it looks like it only buids a list of linked devices and uses this information for state transitions. Said transitions don't look quite atomic by looking at the code. The alsa-lib/test/latency.c code even tries to measure the difference between the number of samples read/written. In short the question is whether I can force a synchronous behavior from my application, or if I need to roll up my sleeves and fix the drivers to see this behavior? Another solution I thought of would be to disable the period events on one of the devices, and handle both devices at once when one period event fires. But I am not sure you can disable all events for an audio device (was on the wish list of Lennart, not sure if it became reality?) Thanks for your feedback. - Pierre

[alsa-devel] [PATCH] cs4236: detect chip in one pass
by Krzysztof Helt 05 Nov '09

05 Nov '09

From: Krzysztof Helt <krzysztof.h1(a)wp.pl> The cs4236 was two step detection with call to the snd_wss_free() between two steps. The snd_wss_free() did not free a sound device created in the snd_wss_create(). This caused an OOPS during module removal as the same sound device was released twice. The same OOPS happened if the cs4236 module loading failed. Fix this by adapting the snd_cs4236_create() to correctly work with chips less capable then cs4236.

[alsa-devel] Seg. fault when using Salsa 0.0.25
by Mogens Lindholdt Lauridsen 05 Nov '09

05 Nov '09

Hi, I got an application which uses Salsa 0.0.25. When I quit this application, it ends with a seg. fault. I don't know if this is caused by my application using Salsa wrongly, or a problem in Salsa. However, I got a fix for it. When my application closes, "hctl_elem_event_handler" is called. And since "helem->private_data" is null, this causes a seg. fault: snd_mixer_elem_t *elem = helem->private_data; snd_mixer_t *mixer = elem->mixer; It seems like: if (!elem) return 0; should have been before: snd_mixer_t *mixer = elem->mixer; An easy way to fix/avoid this is to remove "snd_mixer_t *mixer = elem->mixer;" and replace "mixer" with "elem->mixer" in the function. Like this: static int hctl_elem_event_handler(snd_hctl_elem_t *helem, unsigned int mask) { snd_mixer_elem_t *elem = helem->private_data; //MLN fix: snd_mixer_t *mixer = elem->mixer; int err; if (!elem) return 0; if (mask == SND_CTL_EVENT_MASK_REMOVE) { err = _snd_mixer_elem_throw_event(elem, mask); if (err < 0) return err; remove_simple_element(helem, 1); return 0; } if (mask & SND_CTL_EVENT_MASK_INFO) { remove_simple_element(helem, 0); add_simple_element(helem, elem->mixer); // MLN fix: "mixer" substituted by "elem->mixer" err = snd_mixer_elem_info(elem); if (err < 0) return err; snd_mixer_sort(elem->mixer); // MLN fix: "mixer" substituted by "elem->mixer" } if (mask & SND_CTL_EVENT_MASK_VALUE) { err = update_simple_element(helem, elem); if (err < 0) return err; if (err) { err = snd_mixer_elem_value(elem); if (err < 0) return err; } } return 0; } Kind regards, Mogens

[alsa-devel] Intel HDA - AD1883 Codec - Jack Sense / Detect
by Alan Bennett 05 Nov '09

05 Nov '09

Hello; We have a custom motherboard Intel HDA / AD1883. For output, we connect the headphone jack and the mono / front speaker. We are unable to get audio in Linux (Windows is fine) that activates the front/mono speaker. The headphones work without a problem. However, none of the 4 "model=" strings improve the situation. The headphones always work, but no configuration will activate the onboard front/mono speaker. Is there a way to query the live status of the AD1883 / jack-detect/sense? -Alan

[alsa-devel] VIA VT1828S hda_intel errors
by Robert Hancock 05 Nov '09

05 Nov '09

I've been using the VT1828S codec support from ALSA git for the last few weeks. It seems to work fine, but there are some problems showing up in dmesg: Oct 25 20:46:14 newcastle kernel: ALSA sound/pci/hda/hda_intel.c:683: No response from codec, disabling MSI: last cmd=0x02af0900 Oct 25 20:46:15 newcastle kernel: ALSA sound/pci/hda/hda_intel.c:698: azx_get_response timeout, switching to polling mode: last cmd=0x02af0900 It seems like the cmd isn't always the same, previously it was 0x024f0c00. Is there something bad about this command that could be causing the response timeout? Also, disabling MSI for one occurrence of this seems a bit paranoid.. Also saw one of these: Oct 26 21:13:20 newcastle kernel: hda-intel: IRQ timing workaround is activated for card #0. Suggest a bigger bdl_pos_adj. and PulseAudio also complained: Oct 26 00:27:50 newcastle pulseaudio[16530]: alsa-sink.c: ALSA woke us up to write new data to the device, but there was actually nothing to write! Oct 26 00:27:50 newcastle pulseaudio[16530]: alsa-sink.c: Most likely this is a bug in the ALSA driver 'snd_hda_intel'. Please report this issue to the ALSA developers. Oct 26 00:27:50 newcastle pulseaudio[16530]: alsa-sink.c: We were woken up with POLLOUT set -- however a subsequent snd_pcm_avail() returned 0 or another value < min_avail.

[alsa-devel] Patches for Samsung SoC PCM Controller driver
by Jassi Brar 05 Nov '09

05 Nov '09

Hello, Samsung SoCs S3C2450, S3C64XX and later versions have got PCM controllers which drive what the ALSA stack terms DSP_A/DSP_B formats. Since the S3C ALSA platform driver was named s3c24xx-pcm, which cause direct namespace clash with the new PCM controller drivers, it has been renamed along with some of its local symbols. First two of the following series of patches does that and later ones make ground for and add the PCM controller driver. regards.

[alsa-devel] [RESEND] [PATCH 0/3] Close alsa-lib file descriptors on exec
by Rémi Denis-Courmont 04 Nov '09

04 Nov '09

Hello, The device nodes opened by alsa-lib are private, and are not meant to be used after exec(). Setting the close-on-exec flags avoid leaking devices file descriptors into unintended processes. Further more, the Linux kernel O_CLOEXEC flag is used if available for fully thread-safe operations. configure.in | 2 ++ include/local.h | 23 +++++++++++++++++------ src/control/control_hw.c | 11 ----------- src/hwdep/hwdep_hw.c | 11 ----------- src/pcm/pcm_hw.c | 12 ------------ src/rawmidi/rawmidi_hw.c | 11 ----------- src/seq/seq_hw.c | 11 ----------- src/timer/timer_hw.c | 11 ----------- 8 files changed, 19 insertions(+), 73 deletions(-) -- Rémi Denis-Courmont http://www.remlab.net/

[alsa-devel] [PATCH] sh: add SuperH DAC audio driver for ALSA V4
by Rafael Ignacio Zurita 04 Nov '09

04 Nov '09

This is a port of the sound/oss/sh_dac_audio.c driver. The driver uses an on-chip 8-bit D/A converter, which has a speaker connected to one of its channels, found in several ancient HP machines. For interrupts it uses a high-resolution timer (hrtimer). Tested on SH7709 based hp6xx (HP Jornada 680/690 and HP Palmtop 620lx/660lx). Also, since OSS Emulation works, the old OSS sound/oss/sh_dac_audio.c driver would be obsolete soon, and it could be removed. Changes since V3: - renamed sound/sh/snd_sh_dac_audio.c to sound/sh/sh_dac_audio.c Changes since V2: - renamed include/sound/dac_audio.h to include/sound/sh_dac_audio.h Changes since V1: - moved the platform device code into board code. - dropped dac_audio_sync(), since that code is not needed (it was inherited of the old oss driver). - rewrote the code with style problems.

[alsa-devel] question re: creating a dummy midi device to be readable/writable by alsa/jack
by John Murphy 04 Nov '09

04 Nov '09

hi! I'm currently working on a project to develop a driver for a midi controller that is currently unsupported by Linux. As this is going to be my first project with alsa/midi, I am trying to start by creating a dummy midi device that can be loaded (where? kernel? userspace?), be seen by jack as if it was a normal midi device and then work on my reverse-engineering, debugging, etc. from there. However, looking through the documentation, I'm not exactly sure on how to start building this dummy device. Can anyone help point me in the right direction? Thanks, and sorry for the newbie question! -- john http://ghfdrvtsyup.net/proxxxy

[alsa-devel] [PATCH] cs4236: detect chip in one pass
by Krzysztof Helt 03 Nov '09

03 Nov '09

From: Krzysztof Helt <krzysztof.h1(a)wp.pl> The cs4236 was two step detection with call to the snd_wss_free() between two steps. The snd_wss_free() did not free a sound device created in the snd_wss_create(). This caused an OOPS during module removal as the same sound device was released twice. The same OOPS happened if the cs4236 module loading failed. Fix this by adapting the snd_cs4236_create() to correctly work with chips less capable then cs4236. The snd_cs4236_create() behaves the same as the snd_wss_create() if the chip is less capable than the cs4236. Signed-off-by: Krzysztof Helt <krzysztof.h1(a)wp.pl> --- This is the second version of the patch with added snd_device_free() call in error path. include/sound/wss.h | 1 - sound/isa/cs423x/cs4236.c | 13 +--- sound/isa/cs423x/cs4236_lib.c | 144 ++++++++++++++++++++++------------------- sound/isa/wss/wss_lib.c | 3 +- 4 files changed, 81 insertions(+), 80 deletions(-) diff --git a/include/sound/wss.h b/include/sound/wss.h index 6d65f32..fd01f22 100644 --- a/include/sound/wss.h +++ b/include/sound/wss.h @@ -154,7 +154,6 @@ int snd_wss_create(struct snd_card *card, unsigned short hardware, unsigned short hwshare, struct snd_wss **rchip);

[alsa-devel] [PATCH 0/5] ASoC/MFD/OMAP: TWL4030: APLL_CTL handling change
by Peter Ujfalusi 03 Nov '09

03 Nov '09

Hello, The following series changes the way how the APLL_CTL register is handled by the twl4030 codec related drivers. Moving the configuration of APLL_CTL register from child drivers (specifically from soc codec driver) to the twl4030-codec MFD driver. Because the audio_mclk is static, board specific and can not be changed in runtime, the codec MFD is the right place to configure it early enough, so child can use the hardware correctly. Before this patch for example the APLL_INFREQ was configured first, when the user played or recorded audio via the twl4030. The digital bypass needs correct APLL_INFREQ to be configured in order to work properly. If the digital bypass enabled before any audio activity, in some cases the bypassed audio was not correct. The series also addresses the issue, that after boot-up, neither of the loopbacks was working, because the codec was actually off. Setting the codec->bias_level to _OFF, before setting the codec bias level to STANDBY fixes this issue. This series is on top of Takashi's sound-2.6 topic/asoc branch, which has the twl403-codec MFD and related patches for 2.6.33. It would be really nice, if this series would make it also to the same branch, since this fixes some real anomalies brought in by the cleanup of the twl4030 codec related drivers. These problems were hidden before because of the inconsistent handling of bits and states in the codec driver in the past. Thank you, --- Peter Ujfalusi (5): MFD: TWL4030: Add audio_mclk to the codec platform data OMAP: Configure audio_mclk for twl4030-codec MFD MFD: twl4030-codec: APLL_INFREQ handling in the MFD driver ASoC: TWL4030: Make sure, that the codec is powered on startup ASoC: TWL4030: Do not modify the APLL_CTL register arch/arm/mach-omap2/board-3430sdp.c | 1 + arch/arm/mach-omap2/board-omap3beagle.c | 1 + arch/arm/mach-omap2/board-omap3evm.c | 1 + arch/arm/mach-omap2/board-omap3pandora.c | 1 + arch/arm/mach-omap2/board-overo.c | 1 + arch/arm/mach-omap2/board-zoom2.c | 1 + drivers/mfd/twl4030-codec.c | 40 +++++++++++++++++ include/linux/i2c/twl4030.h | 1 + include/linux/mfd/twl4030-codec.h | 1 + sound/soc/codecs/twl4030.c | 70 +++++++++++------------------ 10 files changed, 75 insertions(+), 43 deletions(-)

[alsa-devel] snd-hdsp driver error?
by Lars Zobbe 03 Nov '09

03 Nov '09

Hi. Talking to one of the pulseaudio developers (*Colin Guthrie*) about a problem with pulseaudio loading modules and my sound card (RME HDSP 9632), I was adviced to inform you about the problem. I'm on ubuntu 9.10, 64bit, kernel 2.6.31 with an amd64 x2 3800+ processor. Symptoms are: Can only make pulseaudio load modules with the deprecated load-module module-detect command, module-udev-detect doesn't detect anything (no sound - only null sink output in padevchooser). I get terrible stuttering. I can remove pulseaudio and make things work, more or less. However, that leaves me without software mixing and apps fighting for the rights to make sound. And more inconveniences (fx. no volume-control). I can play sound from audacity without stuttering by choosing the cardname directly in output HDSP, not ALSA, not pulseaudio. When trying to run alsa-info.sh I get a lot of "not found" errors. So you'll get some manual info (they might have moved som files around in ubuntu 9.10). This is part of my syslog during a boot. (I did the formatting to bold). Nov 2 10:57:32 lars-desktop pulseaudio[1524]: module.c: module-detect is deprecated: Please use module-udev-detect instead of module-detect!

[alsa-devel] Query regarding broken pipe on capturre device
by Ketan Deshpande 03 Nov '09

03 Nov '09

Hello All, I am facing a certain problem in the application development using ALSA.Below is the small description of my problem I am trying to read from the capture device using "snd_pcm_readi"; but sometimes i get a error saying "error reading from capture device : broken pipe -32". Which results in the audio break. I have tried to use the port in blocking as well as non blocking mode but that does not seem to help. I have tried to make sure the buffer sizes match, using the below mentioned formula. ALSA Buffer size in my Apllication = 1024 * 8 = Periodsize * number of periods = HW Buffer size Can you please suggest me, as to what could be the reason for the broken pipe error and how can I get rid of that? regards, -Ketan =====-----=====-----===== Notice: The information contained in this e-mail message and/or attachments to it may contain confidential or privileged information.

[alsa-devel] [PATCH] sh: add SuperH DAC audio driver for ALSA V3
by Rafael Ignacio Zurita 03 Nov '09

This is a port of the sound/oss/sh_dac_audio.c driver. The driver uses an on-chip 8-bit D/A converter, which has a speaker connected to one of its channels, found in several ancient HP machines. For interrupts it uses a high-resolution timer (hrtimer). Tested on SH7709 based hp6xx (HP Jornada 680/690 and HP Palmtop 620lx/660lx). Also, since OSS Emulation works, the old OSS sound/oss/sh_dac_audio.c driver would be obsolete soon, and it could be removed. Changes since V2: - renamed include/sound/dac_audio.h to include/sound/sh_dac_audio.h Changes since V1: - moved the platform device code into board code. - dropped dac_audio_sync(), since that code is not needed (it was inherited of the old oss driver). - rewrote the code with style problems.

[alsa-devel] question on snd_jack_report

>What is event.c? If this is some part of the X.Org server then you'd be >better asking the X folks about how to configure and use the X server, >it rewraps the data it's getting from the kernel. Sorry,it's evtest.c( this program polls /dev/input/eventX and prints the events). Basically when a Headphone is inserted into the jack, driver send snd_jack_report() with the status of present to ALSA. When the respective /dev/input/event5 is read from userspace, it must print the events. I don't see any events when snd_jack_report() is called.

[alsa-devel] Old issue with new details(HP tx2100er headphone jack problem)[RESOLVED]
by Alex Pyattaev 02 Nov '09

02 Nov '09

Hello! I have my laptop for a year now, and ever since i've been trying to fix the sound. Playback works out-of-the box, but recording was always messy. Anyway, recent updates in alsa-driver (shipped with kernel 2.6.31) have completely fixed all sound issues! I have no idea what change actually did the trick, but internal mic was not working before. So, to be exact Hardware: HP tx2100er laptop, AMD64, nforce2 chipset. Audio: Realtek ALC861-VD attached to an nForce2 southbridge, subvendor 0x103c device 0x30e5 see alsa-info output in attachement. Soft: gentoo and all common alsa libs (latest versions). So, thank you for great job and if you need to find out why it works don't hesitate to ask for more info - just mail me. Best regards, Alex Pyattaev

[alsa-devel] FW: question on snd_jack_report
by Kp, Jeeja 02 Nov '09

02 Nov '09

When I call snd_jack_report with the status of the jack, am monitoring the /dev/input/eventX (using event.c) for Userspace events when Headset is inserted and I don't see any events even when snd_jack_report() is called. Is there any specific configuration that is required (xorg.config)? -----Original Message----- From: Mark Brown [mailto:broonie@opensource.wolfsonmicro.com] Sent: Wednesday, October 21, 2009 6:49 PM To: Harsha, Priya Cc: alsa-devel(a)alsa-project.org Subject: Re: [alsa-devel] question on snd_jack_report On Wed, Oct 21, 2009 at 06:22:47PM +0530, Harsha, Priya wrote: Please fix your MUA to wrap at 80 columns, I have once more reflowed your text to fit. > When I call snd_jack_report with the status of the jack, from the user > user space which parameter should I check in the > sys/class/input/input2 to know if the jack is present or not? Assuming you're looking to check the presence of a device in the jack (rather than the presence of the jack itself) then there's nothing in sysfs, you read this information from the device node. See evtest.c (google should show up lots of copies) for sample code doing this.

[alsa-devel] [PATCH 13/16] pcmcia: use dynamic debug infrastructure, deprecate CS_CHECK (sound)
by Dominik Brodowski 02 Nov '09

02 Nov '09

Convert PCMCIA drivers to use the dynamic debug infrastructure, instead of requiring manual settings of PCMCIA_DEBUG. Also, remove all usages of the CS_CHECK macro and replace them with proper Linux style calling and return value checking. The extra error reporting may be dropped, as the PCMCIA core already complains about any (non-driver-author) errors.

OK, your device seems to work if there is a switch of infoframe, ie. coupled with the "HDMI: updating infoframe" message. Note that the message only happens if the audio infoframe don't match up with previous one, _or_ the previous one has been wiped out by some reset operation: Data Island Packet Data ----------------------- The contents of this buffer are cleared during function reset or HD audio link reset. Could you try dumping the audio infoframe data at the beginning of hdmi_switch_infoframe() or hdmi_stop_infoframe_trans(), to check if the previous content have been reset to 0?

Re: [alsa-devel] question on snd_jack_report
by Kp, Jeeja 01 Nov '09

When I call snd_jack_report with the status of the jack, am monitoring the /dev/input/eventX (using event.c) for Userspace events when Headset is inserted and I don't see any events even when snd_jack_report() is called. Is there any specific configuration that is required (xorg.config)? -----Original Message----- From: Mark Brown [mailto:broonie@opensource.wolfsonmicro.com] Sent: Wednesday, October 21, 2009 6:49 PM To: Harsha, Priya Cc: alsa-devel(a)alsa-project.org Subject: Re: [alsa-devel] question on snd_jack_report On Wed, Oct 21, 2009 at 06:22:47PM +0530, Harsha, Priya wrote: Please fix your MUA to wrap at 80 columns, I have once more reflowed your text to fit. > When I call snd_jack_report with the status of the jack, from the user > user space which parameter should I check in the > sys/class/input/input2 to know if the jack is present or not? Assuming you're looking to check the presence of a device in the jack (rather than the presence of the jack itself) then there's nothing in sysfs, you read this information from the device node. See evtest.c (google should show up lots of copies) for sample code doing this.

[alsa-devel] [PATCH] cs4236: detect cs4236+ chip in one pass
by Krzysztof Helt 01 Nov '09

01 Nov '09

From: Krzysztof Helt <krzysztof.h1(a)wp.pl> The cs4236 was two step detection with call to the snd_wss_free() between two steps. The snd_wss_free() did not free a sound device created in the snd_wss_create(). This caused an OOPS during module removal as the same sound device was released twice. The same OOPS happened if the cs4236 module loading failed. Fix this by adapting the snd_cs4236_create() to correctly work with chips less capable then cs4236. The snd_cs4236_create() behaves the same as the snd_wss_create() if the chip is less capable than the cs4236. Signed-off-by: Krzysztof Helt <krzysztof.h1(a)wp.pl> --- It is related to the kernel bug #13379. If the snd-cs4236 is forced to be loaded with isapnp=0 and wrong control port is given, the driver OOPS and it is not possible to reload the driver until reboot. The OOPS from Wim Osternholt is below: ALSA sound/isa/cs423x/cs4236_lib.c:313: CS4236: [0x210] C1 (version) = 0xff, ext = 0xe8 ALSA sound/isa/cs423x/cs4236_lib.c:316: CS4236+ chip detected, but control port 0x210 is not valid BUG: unable to handle kernel NULL pointer dereference at 00000018 IP: [<c02285c6>] release_resource+0x16/0x48 *pde = 00000000 Oops: 0000 [#1] SMP last sysfs file: /sys/devices/pci0000:00/0000:00:01.1/ide1/1.0/block/hdc/size Modules linked in: snd_cs4236(+) snd_wss_lib snd_opl3_lib snd_hwdep snd_mpu401_uart snd_rawmidi snd_pcm snd_timer snd_page_alloc snd_mixer_oss sd_mod svgalib_helper uhci_hcd neofb cfbcopyarea vgastate cfbimgblt cfbfillrect usbcore xircom_cb Oct 29 12:43:16 barbapapa Pid: 5317, comm: modprobe Not tainted (2.6.30-gentoo-r8 #3) 2645310 EIP: 0060:[<c02285c6>] EFLAGS: 00010206 CPU: 0 EIP is at release_resource+0x16/0x48 EAX: c066a91c EBX: c8f40d80 ECX: 00000018 EDX: cad81fb0 ESI: c83c0000 EDI: 00002fff EBP: c8379df8 ESP: c8379df4 DS: 007b ES: 007b FS: 00d8 GS: 0033 SS: 0068 Process modprobe (pid: 5317, ti=c8378000 task=c8322be0 task.ti=c8378000) Stack: c8f40d80 c8379e04 c04186f3 c82ca000 c8379e10 cad81f38 c8f40240 c8379e18 cad81fbb c8379e28 c041883e c83c0000 00002000 c8379e3c c04188f2 c83c0000 c83c0000 c8f42d80 c8379e48 c04147e7 00000000 c8379e74 c04152a3 c83c01b4 Call Trace: [<c04186f3>] ? release_and_free_resource+0xf/0x1c [<cad81f38>] ? snd_wss_free+0xe/0x86 [snd_wss_lib] [<cad81fbb>] ? snd_wss_dev_free+0xb/0xd [snd_wss_lib] [<c041883e>] ? snd_device_free+0x8d/0xea [<c04188f2>] ? snd_device_free_all+0x57/0x79 [<c04147e7>] ? snd_card_do_free+0x6e/0xd2 [<c04152a3>] ? snd_card_free+0x7f/0x89 [<cad9973d>] ? snd_cs423x_isa_probe+0x3e/0x4d [snd_cs4236] [<cad996ff>] ? snd_cs423x_isa_probe+0x0/0x4d [snd_cs4236] [<c03b9802>] ? isa_bus_probe+0x1c/0x1f [<c03b60b7>] ? driver_probe_device+0x8e/0x102 [<c03b62ee>] ? __device_attach+0x0/0x32 [<c03b6316>] ? __device_attach+0x28/0x32 [<c03b5590>] ? bus_for_each_drv+0x39/0x63 [<c03b61ee>] ? device_attach+0x45/0x59 [<c03b62ee>] ? __device_attach+0x0/0x32 [<c03b552d>] ? bus_attach_device+0x1e/0x48 [<c03b44cd>] ? device_add+0x331/0x471 [<c034d63e>] ? kobject_init+0x35/0x5a [<c03b461f>] ? device_register+0x12/0x15 [<c03b9994>] ? isa_register_driver+0xde/0x146 [<cada1000>] ? alsa_card_cs423x_init+0x0/0x74 [snd_cs4236] [<cada1012>] ? alsa_card_cs423x_init+0x12/0x74 [snd_cs4236] [<c0201141>] ? do_one_initcall+0x4c/0x131 [<c024445f>] ? sys_init_module+0x87/0x190 [<c02029f5>] ? syscall_call+0x7/0xb Code: 3b 4e 04 8b 55 ec 7c e5 7f 04 3b 16 72 df 59 5b 5b 5e 5f 5d c3 55 89 e5 53 89 c3 b8 1c a9 66 c0 e8 7b de 2d 00 8b 4b 10 83 c1 18 <8b> 11 85 d2 74 19 39 da 75 10 8b 42 14 89 01 31 c0 c7 42 10 00 [<c02285c6>] release_resource+0x16/0x48 SS:ESP 0068:c8379df4 CR2: 0000000000000018 include/sound/wss.h | 1 - sound/isa/cs423x/cs4236.c | 13 +--- sound/isa/cs423x/cs4236_lib.c | 143 ++++++++++++++++++++++------------------- sound/isa/wss/wss_lib.c | 3 +- 4 files changed, 80 insertions(+), 80 deletions(-) diff --git a/include/sound/wss.h b/include/sound/wss.h index 6d65f32..fd01f22 100644 --- a/include/sound/wss.h +++ b/include/sound/wss.h @@ -154,7 +154,6 @@ int snd_wss_create(struct snd_card *card, unsigned short hardware, unsigned short hwshare, struct snd_wss **rchip);

[alsa-devel] [patch] snd-pcsp: add nopcm mode
by Stas Sergeev 01 Nov '09

01 Nov '09

Hello. Currently, if the high-res timers are unavailable, snd-pcsp does not initialize. People who choose it over pcspkr, loose their console beeps in that case and get annoyed. With this patch, the console beeps remain regardless of the high-res timers. Additionally, the "nopcm" modparam is added to forcibly disable the PCM capabilities of the driver.

[alsa-devel] [USB] alsa-lib 1.2.21[a] broke USB audio buffering - regression
by Shawn Starr 31 Oct '09

31 Oct '09

Hello ALSA developers, I seem have noticed a problem with USB audio buffering. Prior to using *buntu, which uses ALSA 1.2.20 I had no problems with using my USB webcam for audio. When I switched to Debian, which uses ALSA 1.2.21a I noticed USB audio became choppy. The device in question is a QuickCam Pro 9000 webcam. I can confirm this to be the case since taking the 1.2.20 source and rebuilding it on Debian causes the audio choppiness problem to stop. Thanks, Shawn.

[alsa-devel] [RFC 0/2] ASoC: remove io_mutex
by ext-eero.nurkkala＠nokia.com 30 Oct '09

30 Oct '09

From: Eero Nurkkala <ext-eero.nurkkala(a)nokia.com> This RFC set addresses the existence of io_mutex. A safer method is introduced - but it changes the semantics quite a bit, as now all drivers calling snd_soc_update_bits() will need to make sure the codec mutex is taken. snd_soc_test_bits() - function does not need to take the io_mutex at all - all calls to it have the codec mutex already taken. Warning: Not even compile tested! Possible drawback: dapm_power_widgets() may hold the codec mutex for a few ms, which may be too long; meanwhile, calls to snd_soc_update_bits() are stalled. Of course we wish optimal performance and maybe the codec mutex should only be taken for such registers that contain both volume and dapm bits... Ideas, comments, all welcome.

[alsa-devel] [PATCH 3/14] sound/parisc: Move dereference after NULL test
by Julia Lawall 30 Oct '09

30 Oct '09

From: Julia Lawall <julia(a)diku.dk> If the NULL test on h is needed in snd_harmony_mixer_init, then the dereference should be after the NULL test. Actually, there is a sequence of calls: snd_harmony_create, then snd_harmony_pcm_init, and then snd_harmony_mixer_init. snd_harmony_create initializes h, but may indeed leave it as NULL. There was no NULL test at the beginning of snd_harmony_pcm_init, so I have added one. The NULL test in snd_harmony_mixer_init is then not necessary, but in case the ordering of the calls changes, I have left it, and moved the dereference after it. A simplified version of the semantic match that detects this problem is as follows (http://coccinelle.lip6.fr/): // <smpl> @match exists@ expression x, E; identifier fld; @@ * x->fld ... when != $x = E\|&x$ * x == NULL // </smpl> Signed-off-by: Julia Lawall <julia(a)diku.dk> --- sound/parisc/harmony.c | 6 +++++- 1 files changed, 5 insertions(+), 1 deletions(-) diff --git a/sound/parisc/harmony.c b/sound/parisc/harmony.c index e924492..f47f9e2 100644 --- a/sound/parisc/harmony.c +++ b/sound/parisc/harmony.c @@ -624,6 +624,9 @@ snd_harmony_pcm_init(struct snd_harmony *h) struct snd_pcm *pcm; int err; + if (snd_BUG_ON(!h)) + return -EINVAL; + harmony_disable_interrupts(h); err = snd_pcm_new(h->card, "harmony", 0, 1, 1, &pcm); @@ -865,11 +868,12 @@ snd_harmony_mixer_reset(struct snd_harmony *h) static int __devinit snd_harmony_mixer_init(struct snd_harmony *h) { - struct snd_card *card = h->card; + struct snd_card *card; int idx, err; if (snd_BUG_ON(!h)) return -EINVAL; + card = h->card; strcpy(card->mixername, "Harmony Gain control interface"); for (idx = 0; idx < HARMONY_CONTROLS; idx++) {

[alsa-devel] [PATCH] remove OSS Ensoniq SoundScape driver
by Krzysztof Helt 30 Oct '09

30 Oct '09

From: Krzysztof Helt <krzysztof.h1(a)wp.pl> The OSS driver for Ensoniq SoundScape cards is broken after conversion to mutexes and a new ALSA snd-sscape driver handles all devices handled by the OSS one. The ALSA driver was tested with these cards: Spea V7 MediaFX Ensoniq Soundscape Elite Ensoniq Soundscape VIVO (this card is not handled by the OSS driver) Signed-off-by: Krzysztof Helt <krzysztof.h1(a)wp.pl> --- Theodore Allen confirmed that that the new driver works for his Ensoniq Soundscape Elite card (both MIDI and PCM): "I decided to upgrade to 2.6.28.10 from 2.6.28. I also put the firmware in the /lib/firmware directory. Now the MIDI seems to work on most files. There are a few that sound odd, but perhaps it's the midi map. I have no idea why the driver allowed the sscape_ctl program to load the firmware earlier, but it doesn't now. Was there an ALSA change between 2.6.28 and 2.6.28.10? Less happily, the sound seems now to have a very faint "zzzt" kind of "click" just before playing, which I think it didn't with 2.6.28. I'll verify that after I reboot into the old kernel." I will investigate the PCM issue after he confirms that it is a regression.

[alsa-devel] [PATCH] ALSA: Cleanup redundant tests on unsigned
by Roel Kluin 30 Oct '09

30 Oct '09

The variables are unsigned so the test `>= 0' is always true, the `< 0' test always fails. In these cases the other part of the test catches wrapped values. In dac_audio_write() there does not occur a test for wrapped values, but the test appears redundant.

[alsa-devel] [PATCH 2/14] sound: Move dereference after NULL test and drop unnecessary NULL tests
by Julia Lawall 30 Oct '09

30 Oct '09

From: Julia Lawall <julia(a)diku.dk> In pcm.c, if the NULL test on pcm is needed, then the dereference should be after the NULL test. In dummy.c and ali5451.c, the context of the calls to snd_card_dummy_new_mixer and snd_ali_free_voice show that dummy and pvoice, respectively cannot be NULL. A simplified version of the semantic match that detects this problem is as follows (http://coccinelle.lip6.fr/): // <smpl> @match exists@ expression x, E; identifier fld; @@ * x->fld ... when != $x = E\|&x$ * x == NULL // </smpl> Signed-off-by: Julia Lawall <julia(a)diku.dk> --- sound/core/pcm.c | 5 +++-- sound/drivers/dummy.c | 2 -- sound/pci/ali5451/ali5451.c | 2 +- diff --git a/sound/core/pcm.c b/sound/core/pcm.c index 0c14401..c69c60b 100644 --- a/sound/core/pcm.c +++ b/sound/core/pcm.c @@ -953,11 +953,12 @@ static int snd_pcm_dev_register(struct snd_device *device) struct snd_pcm_substream *substream; struct snd_pcm_notify *notify; char str[16]; - struct snd_pcm *pcm = device->device_data; + struct snd_pcm *pcm; struct device *dev; - if (snd_BUG_ON(!pcm || !device)) + if (snd_BUG_ON(!device || !device->device_data)) return -ENXIO; + pcm = device->device_data; mutex_lock(&register_mutex); err = snd_pcm_add(pcm); if (err) { diff --git a/sound/drivers/dummy.c b/sound/drivers/dummy.c index 6ba066c..146ef00 100644 --- a/sound/drivers/dummy.c +++ b/sound/drivers/dummy.c @@ -808,8 +808,6 @@ static int __devinit snd_card_dummy_new_mixer(struct snd_dummy *dummy) unsigned int idx; int err; - if (snd_BUG_ON(!dummy)) - return -EINVAL; spin_lock_init(&dummy->mixer_lock); strcpy(card->mixername, "Dummy Mixer"); diff --git a/sound/pci/ali5451/ali5451.c b/sound/pci/ali5451/ali5451.c index b458d20..aaf4da6 100644 --- a/sound/pci/ali5451/ali5451.c +++ b/sound/pci/ali5451/ali5451.c @@ -973,7 +973,7 @@ static void snd_ali_free_voice(struct snd_ali * codec, void *private_data; snd_ali_printk("free_voice: channel=%d\n",pvoice->number); - if (pvoice == NULL || !pvoice->use) + if (!pvoice->use) return; snd_ali_clear_voices(codec, pvoice->number, pvoice->number); spin_lock_irq(&codec->voice_alloc);

[alsa-devel] [PATCH 00/11] Intel IbexPeak HDMI codec support
by Wu Fengguang 30 Oct '09

30 Oct '09

Hi Takashi, This series adds support for the Intel IbexPeak HDMI codec, which can connect up to 3 monitors and support 2 independant A/V pipes. The patches are tested OK on IbexPeak and G45. DisplayPort is also working with another in-house KMS patch. However we have not tested dual monitor configurations (which should be rare for now). Thanks, Fengguang

SuperH FSI device have the hardware limitation to use DMA. If DMA is used, LCD output will be broken. Maybe there are some solution. But I don't know how to do it now.

Hm, I don't see any affecting changes between 2.6.30 and 31. Just as a test, could you copy sound/usb/*.[ch] from 2.6.30 tree to 2.6.31 or 32-rc and check whether the same problem appears? Takashi

Im developing ASoC Driver for an SoC (I2S based). When testing playback with aplay, I get 1 buffers worth of data played back (10 periods) then playback stops due to a XRUN when my dma list wraps back to the start because the available data >= stop_threshold ??

[alsa-devel] Digital distortion when converting Mono to Stereo?
by Daniel Mack 29 Oct '09

29 Oct '09

While testing with our ASoC enabled embedded platform, we observed a strange phenomena with Mono audio files. We used external audio test equipment for SNR/THD analysis and used a mono wav file (16bit, 44.1 KHz) which plays a simple sweep from ~10Hz to ~20KHz. As the hardware output is Stereo, an implicit conversion takes places (don't know which part of ALSA actually does it, though). Strangely, the measurement showed a phantom frequency which looks like the sweeping test signal frequency was somehow 'mirrored' at 11.025KHz (fs/4). This phantom noise becomes stronger the lower its frequency gets. So while sweeping, those two peaks were approaching each other, they met at 11KHz, and when the 'real' peak aproached 20KHz, the phantom was at something like 1KHz and had comparable level than the 'real' signal. All that was much stronger on one channel and barely there, but still measurable, on the other one. We first though about an analog filter issue, then suspected the digital input stream, but eventually it turned out that with the same test file in stereo, all these effects suddenly went away. So there must be something in the chain from aplay to the actual PXA SSP ports which adds considerable digital distortion to one channel when converting from Mono to Stereo. I didn't dig any deeper, but still wanted to let you know. Can anyone think of a possible reason for that? It doesn't harm us in our application as we will never play Mono audio eventually, but I guess it could affect others. Thanks, Daniel

[alsa-devel] aloop / asym (ttable-bindings) Merging audio stream with SIP/Skype - .asoundrc struggle
by yvonne barrymore 28 Oct '09

28 Oct '09

(NOTE: RESENT as received an email the alsa-devel mailinglist had moved.) OBJECTIVE: merge (mplayer cli or aplay) audio stream with SIP/Skype so that music can be heard during chat. Really need help from a developer I think as alsa-users mailinglist not able to help during past 2 weeks. 2 weeks happily studying alsa/plugins, posted/searched on mailing lists and tried irc as well. Could really use a guru assist. I get the parts mostly, though obviously not how it all comes together in an .asoundrc. - aloop driver is installed. After scores of attempts now wondering: maybe having the music track playing on it's own soundcard or loopback and having that merge into the microphone? channel of sip/skype's soundcard. Like, have the music play out on the intel card 0, and loopback through aloop card 1, then merge that with asym/dmix onto sip/skype's headset card 2 ???? I kinda know what the plugs do, though not how to hook-up through .asoundrc. I've found 3 or 4 great posts on alsa-devel and alsa-users though ultimately for me just glimmers of working. Rather than glut up the list here I've only posted my aplay -l Can anyone comment on exactly what I'd put in my .asoundrc? What the flow/parts would be even? To stop stuttering (fighting for card control ? etc.) I guessed that the music playing on it's own card might be good? Very happy to post what I've got though thought I should ask first if anyone has found a best practice for this. **** List of PLAYBACK Hardware Devices **** card 0: Intel [HDA Intel], device 0: ALC1200 Analog [ALC1200 Analog] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 1: ALC1200 Digital [ALC1200 Digital] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: Intel [HDA Intel], device 6: Si3054 Modem [Si3054 Modem] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: Loopback [Loopback], device 0: Loopback PCM [Loopback PCM] Subdevices: 8/8 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 Subdevice #2: subdevice #2 Subdevice #3: subdevice #3 Subdevice #4: subdevice #4 Subdevice #5: subdevice #5 Subdevice #6: subdevice #6 Subdevice #7: subdevice #7 card 1: Loopback [Loopback], device 1: Loopback PCM [Loopback PCM] Subdevices: 8/8 Subdevice #0: subdevice #0 Subdevice #1: subdevice #1 Subdevice #2: subdevice #2 Subdevice #3: subdevice #3 Subdevice #4: subdevice #4 Subdevice #5: subdevice #5 Subdevice #6: subdevice #6 Subdevice #7: subdevice #7 card 2: default [C-Media USB Headphone Set ], device 0: USB Audio [USB Audio] Subdevices: 1/1 Subdevice #0: subdevice #0

[alsa-devel] A question about the soc jack status
by Joonyoung Shim 28 Oct '09

28 Oct '09

Hi, all. I have a question about soc jack. I know the soc jack reports the jack status when the jack status is change only. For example when the jack is inserted or released, the soc jack reports the jack status to user via input subsystem. But i want to know the jack status always regardless of the event to insert or release a jack. For example we can check the jack status always if the jack status is reported via sysfs file. So, is there how to know the jack status always the currently?

Hello, I still have my problem that I have a constant clicking noise coming out of my boxes with a sigmatel 9202 sound chip on intel-hda (Poulsbo) soundcard. I now found two patches for the alsa driver that can be applied on a 2.6.24 kernel. Those patches are exactly for the sigmatel 9202, so possibly they would fix my problem. http://redirectingat.com/?id=593X1004&url=http%3A%2F%2Flists.moblin.org%2Fpi permail%2Fcommits%2F2007-December%2F001232.html and http://redirectingat.com/?id=593X1004&url=http%3A%2F%2Fwww.google.com%2Furl% 3Fsa%3Dt%26source%3Dweb%26ct%3Dres%26cd%3D9%26ved%3D0CDAQFjAI%26url%3Dhttp%2 53A%252F%252Fwww.soulinfo.com%252F~hugang%252Ftmp%252Fubuntu-hardy%25252Btux onice%252Fdebian%252Fbinary-custom.d%252Flpia%252Fpatchset%252F0010-hda_sigm atel.patch%26ei%3D4AfoSs24OpeG_Abfy7yGCA%26usg%3DAFQjCNH-mrDdDcgvhNh_eM5hy4W hepUtUQ%26sig2%3D2fK3ED_DyaLSexlPlkFufQ I found both patches here: http://software.intel.com/en-us/articles/patches-for-moblin-kernel-on-menlow / I think these patches aren't yet completely integrated into alsa driver 1.0.21?

I think this is not the easiest job but I appreciate any help! :) Thank you very much, Cheers Christian

[alsa-devel] What can change after suspend ?
by Giuliano Pochini 28 Oct '09

28 Oct '09

I'm adding suspend/resume support to echoaudio drivers. I was reading /Documentation/power/pci.txt: " pci_set_power_state(PCI_D0); pci_restore_state(); /* device's irq possibly is changed, driver should take care */ " The card does not support D[0-3] states. The driver suspends the card by turning the DSP off, without changing the PCI state. Can IRQ, memory mapped regions, whatever, change on resume ? Are pci_save_state() and pci_enable_wake() useful/required in this case ? -- Giuliano.

[alsa-devel] Problems with snd_pcm_writei() function
by Douglas Lopes Pereira 27 Oct '09

27 Oct '09

Hi, I'm modifying an application that calls snd_pcm_writei() function from libasound2-dev (on verstion 1.0.16-2). I does work. I'm splitting my audio data into 160 bytes buffers but when buffer with different size is passed to that function I hear a noise (like 'Krrr') on my audio device. I tried to add zeroed bytes to complete the buffer but it didn't work. I tried to ignore the last buffer and it worked but with some side effects: No other operation worked properly after that. Please, can anyone help? Thanks in advance. Regards, Douglas

Good question. I guess I made it wrong again. The checksum field may be auto-generated by hardware: The HDMI specification defines a data island packet with a header of 4 bytes (3 bytes content + 1 byte ECC) and packet body of 32 bytes (28 bytes content and 4 bytes ECC). Note that the ECC bytes are not present in the DIP content populated by software and are hardware generated. - from HDA-034-A2.pdf > Also, what does the GP[1..3] buffers hold? They are for ACP and ISRC1/2 (not utilized by driver for now): When audio data is transmitted over the HDMI link, associated control information is transmitted as "Data Island Packets" over the link. Some of the packet types applicable to audio are ACP packets (for content protection), ISRC1/2 (for content info), Audio infoframe etc. For a detailed list of control packets and respective formats, please refer to the HDMI specification. > Anyway, even with the above for loops fixed, I still have the same > problems (not that weird perhaps since all the bytes that were being > missed anyway defaulted to 0x00). Yeah. I have always be wondering whether the checksum field is necessary. Removing it seems to change nothing. Anyway the number 13 is a strong indication for removing it. > I've noticed that if a run this: > > while true; do > speaker-test -t wav -c 8 -D hdmi -l 1 > speaker-test -t wav -c 2 -D hdmi -l 1 > done > > it always works, but this: > > while true; do > speaker-test -t wav -c 2 -D hdmi -l 1 > done > > doesn't.

The attached (combined) patch have bits to do sticky infoframe. However my tests show that it didn't improve the 0.5s delay.. Thanks, Fengguang

[alsa-devel] Patches for libasound to support upcoming Audacious 2.2
by John Lindgren 26 Oct '09

26 Oct '09

Hello, I've been working on the ALSA output for the upcoming 2.2 release of Audacious media player and have run into some problems in snd_device_name_hint, which is now used to show the user a list of possible output devices. I've written patches which correct those problems. The biggest problem is that in several places, functions called by snd_device_name_hint call snd_config_delete on sections of the config returned by snd_config_search. Once these sections are deleted, future calls to snd_pcm_open fail miserably. ALSA lib conf.c:4600:(snd_config_expand) Unknown parameters CARD=ICH6,DEV=0 ALSA lib pcm.c:2211:(snd_pcm_open_noupdate) Unknown PCM front:CARD=ICH6,DEV=0 alsa-gapless: snd_pcm_open failed: Invalid argument. ALSA lib pcm.c:2211:(snd_pcm_open_noupdate) Unknown PCM pulse alsa-gapless: snd_pcm_open failed: No such file or directory. A smaller but still annoying problem shows up only once the offending snd_config_delete calls are taken out: software devices, such as "pulse" and "null" are listed twice or three times depending on how many hardware devices I have plugged in. A third problem is that "ctl" seems to be arbitrarily left out of the list of device types that snd_device_name_hint will search for. I've added it to the list in this patch, and it seems to work fine. Finally, a performance issue: snd_device_name_hint indirectly calls snd_dlopen frequently with the parameter name == NULL, meaning to open libasound.so itself. In this case, snd_dlopen calls dladdr every call to find out the path to libasound.so. Caching this path within snd_dlopen so that dladdr is called only once speeds up the execution time of snd_device_name_hint (a somewhat slow call) by 40%. I am attaching three patches that fix these problems: - src/conf.c - src/dlmisc.c - src/control/namehint.c Peace, John Lindgren

[alsa-devel] [PATCH 0/4 v2] MFD/OMAP/ASoC: MFD device for twl4030 codec submodule
by Peter Ujfalusi 25 Oct '09

25 Oct '09

Hello, Changes from the first series: - twl4030-codec MFD driver is using the mfd-core API (and selects MFD_CORE) - Added Acked-by: Tony Lindgren <tony(a)atomide.com> to the patch for the OMAP board files - User selectable Kconfig is removed for the TWL4030_CODEC - soc codec driver patch separated: - Change the header file, and use the include/linux/mfd/twl4030-codec.h for register definitions - The actual change in the soc codec driver - Module alias corrected in soc codec driver - The bias is brought up when the driver comes up, rather than in soc probe. - The soc codec driver is selecting the TWL4030_CODEC driver The series applies on top of sound-2.6:topic/asoc branch Commit message from the first series: The following series adds new MFD device on top of the twl4030 MFD device for the codec part of the chip, and also converts the soc audio driver to use the correct probing (device model). Reason for the twl4030_codec MFD: the vibra control is actually in the codec part of the twl4030. If both the vibra and the audio functionality is needed from the twl4030 at the same time, than they need to control the codec power and APLL at the same time without breaking the other driver. Also these two has to be able to work without the need for the other driver. The proposed solution: Register twl4030_codec as a child for the twl4030 mfd. twl4030_codec is also and mfd and at the moment it has two child: twl4030_codec_audio: for audio codec twl4030_codec_vibra: for vibra driver The twl4030_codec mfd registers the devices for audio and vibra (if the platform data is not NULL for them), and has - at the moment - functions to enable/disable resources, each of these resources has ref-counts, so the twl4030_codec knows, when the resource is need to be turned on or off. The interface is quite simple: int twl4030_codec_enable_resource(enum twl4030_codec_res id); int twl4030_codec_disable_resource(enum twl4030_codec_res id); These functions are returning the content of the given register after the modification (or negative value, if error - the error handling need to be revisited in a near future), so that the caller can update it's local cache if it need to do (the audio driver needs it). There are two resource defined: TWL4030_CODEC_RES_POWER: Controlling the power of the codec TWL4030_CODEC_RES_APLL: For APLL The vibra driver is not part of this series. I have also included a patch, which changes the board files for those, which in my knowledge uses the twl4030 codec as audio device. I might missed some boards... To-Do list: - add the actual vibra driver ;) - coexistence related fixes for the audio and vibra driver - move all audio related configuration from soc machine drivers to the board files (if any) --- Peter Ujfalusi (4): MFD: twl4030: add twl4030_codec MFD as a new child to the core OMAP: Platform support for twl4030_codec MFD ASoC: TWL4030: use the twl4030-codec.h for register descriptions ASoC: TWL4030: Driver registration via twl4030_codec MFD arch/arm/mach-omap2/board-3430sdp.c | 9 + arch/arm/mach-omap2/board-omap3beagle.c | 9 + arch/arm/mach-omap2/board-omap3evm.c | 9 + arch/arm/mach-omap2/board-omap3pandora.c | 9 + arch/arm/mach-omap2/board-overo.c | 9 + arch/arm/mach-omap2/board-zoom2.c | 9 + drivers/mfd/Kconfig | 6 + drivers/mfd/Makefile | 1 + drivers/mfd/twl4030-codec.c | 241 ++++++++++++++++++++++++++ drivers/mfd/twl4030-core.c | 14 ++ include/linux/i2c/twl4030.h | 18 ++ include/linux/mfd/twl4030-codec.h | 271 ++++++++++++++++++++++++++++++ sound/soc/codecs/Kconfig | 1 + sound/soc/codecs/twl4030.c | 203 ++++++++++++++--------- sound/soc/codecs/twl4030.h | 242 +-------------------------- 15 files changed, 738 insertions(+), 313 deletions(-) create mode 100644 drivers/mfd/twl4030-codec.c create mode 100644 include/linux/mfd/twl4030-codec.h

[alsa-devel] Problems in snd_device_name_hint
by John Lindgren 25 Oct '09

25 Oct '09

Hello, I haven't frequented the alsa-devel list in the past, but Debian's maintainer apparently prefers that I go directly to the ALSA developers. While developing a new ALSA output plugin for Audacious audio player, I have run into several problems in snd_device_name_hint. I've already described the problems in the Debian bug tracker and made up some patches, which I would like someone to review. Here are the links: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=549531 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=552240 I'm also attaching the patches here. Peace, John Lindgren

The kernel recently introduced the O_CLOEXEC open flag, to support thread-safe close-on-exec. The only way to leverage this is for ALSA-lib to set close-on-exec itself when it opens a file (whether by default or when the application requests it). That said, I still fail to see any potential use case to not set the flag. Since ALSA-lib won't let the application know about the file handles, any application cannot a use them across exec() in the first place. For the reference, glibc is now setting close-on-exec in similar cases, e.g. syslog(). > I guess the alternative would be to shutdown all open PCMs, etc. in > ALSA in the child process after forking and before the exec, so that > they don't end up still open for the new process.. I suspect such an approach would be painful both for ALSA and for the applications. From ALSA, this would need safety with regards to fork in another thread. That probably requires pthread_atfork() *glurp* if ALSA is to keep its SMP & thread-safety promise *ouch*. From the application, this require calling an ALSA function between fork and exec. That would forbid using system(), popen() or -faster- posix_spawn*(). That also means linking to ALSA in every place that executes. Considering that VLC is heavily plugin- based, this would be so impractical that I'd even rather scan through /proc/self/fd... -- Rémi Denis-Courmont http://git.remlab.net/cgi-bin/gitweb.cgi?p=vlc-courmisch.git;a=summary

[alsa-devel] What is the meaning of the mask values in the pcm hw constraints struct ?
by Neil Jones 24 Oct '09

24 Oct '09

I am developing an ASoC driver for a custom SoC (not in tree yet), I have written the platform and board modules and my hardware detects and installs ok, im now trying to play sound using aplay but im having issues. I get the error "aplay: set_params:1022: Unable to install hw params:" I have traced the problem to a failing ioctl call (snd_pcm_playback_ioctl) the error occurs in snd_pcm_hw_refine when refining the mask for the SNDRV_PCM_HW_PARAM_ACCESS mask, all the bit fields in my runtime->hw_constraints are zero for this field, but the requested params have the value 7, Im not sure what this means, the SNDRV_PCM_ACCESS_xxx defines in asound.h only go upto 4 ? I have attached logs below (with RULES_DEBUG turned on) hopefully this may shed some light.

[alsa-devel] Exemple of source code for capture without using callback
by brunal2496 gmail 23 Oct '09

23 Oct '09

Hi all, it's my first time on this list and my knowledge about using poll() mutex and thread creation is a bit far away from now, so please, if this list is the wrong place for such a question, could you point me in the right direction? Does anyone can point me a place to find a good exemple of source code for capturing sound with alsa without using callbacks? I'm trying to interface a voice recognition software with the alsa drivers. I have to get audio from alsa convert it and then send to the recognition engine. I've read everywhere that using callback is a bad method to use the alsa drivers. As the recognition software is a server, it needs to be synchronized with my application. And so my main() cannot loop on a endless loop with the snd_pcm_readi() function inside. My first idea was to create a new thread and to let this thread running with a endless loop that do the snd_pcm_readi() and send the buffer to the recognition software. But I 've read the existence of smd_pcm_poll_descriptors() function. For now I not shure was it is for and how to use it properly. What do you think? I'm sorry if my question is a real newbie question, but exemple online are only for playback not capture. Many thanks for all your answers. Bruno.

[alsa-devel] Developing and cross-compiling an ASoC driver
by Szabolcs Erki 22 Oct '09

22 Oct '09

Hello, I recently designed a custom board based on an AT91SAM9 microcontroller connected with an ADC via I2S. In the project we need a data acquisition application, which can store audio stream to wav files. On my opinion arecord fulfills our requirements. The "only" thing we have to do is writing an ASoC driver especially for the ADC (ADS1274), and cross compile it to the Linux4SAM embedded Linux environment. I didn't find any suitable description how to do a cross-platform driver development process. Could you please give me some introduction how to: - cross compile alsa-driver (AFAIK ASoC is part of it, and ALSA is part of the linux kernel), and alsa-utils (for getting arecord) - cross compile the newly developed alsa driver - integrate ASoC and the custom driver to the patched kernel (Linux4SAM) and cross compile them to one image. Thank you for your help in advance! Br, Szabolcs Erki

[alsa-devel] patchmix application for EMU1616m
by Dominik Zalewski 22 Oct '09

22 Oct '09

Is there anybody working on patchmix application for alsa? I'm wondering what would be the guidelines. - Should it be a clone of a patchmix for Windows: a separate program? - Or maybe there is already some infrastructure in Alsa that should be extended with that functionality? - Alsamixer already has some of that functionality, should be replicated in new patchmix application? - Are there any restrictions for the GUI libraries that may be used? - Does it have to be written in C/C++, or is Java also applicable? -- Dominik Zalewski

[alsa-devel] [PATCH 0/4] twl4030 codec as MFD device
by Peter Ujfalusi 22 Oct '09

22 Oct '09

Hello, The following series adds new MFD device on top of the twl4030 MFD device for the codec part of the chip, and also converts the soc audio driver to use the correct probing (device model). Reason for the twl4030_codec MFD: the vibra control is actually in the codec part of the twl4030. If both the vibra and the audio functionality is needed from the twl4030 at the same time, than they need to control the codec power and APLL at the same time without breaking the other driver. Also these two has to be able to work without the need for the other driver. The proposed solution: Register twl4030_codec as a child for the twl4030 mfd. twl4030_codec is also and mfd and at the moment it has two child: twl4030_codec_audio: for audio codec twl4030_codec_vibra: for vibra driver The twl4030_codec mfd registers the devices for audio and vibra (if the platform data is not NULL for them), and has - at the moment - functions to enable/disable resources, each of these resources has ref-counts, so the twl4030_codec knows, when the resource is need to be turned on or off. The interface is quite simple: int twl4030_codec_enable_resource(enum twl4030_codec_res id); int twl4030_codec_disable_resource(enum twl4030_codec_res id); These functions are returning the content of the given register after the modification (or negative value, if error - the error handling need to be revisited in a near future), so that the caller can update it's local cache if it need to do (the audio driver needs it). There are two resource defined: TWL4030_CODEC_RES_POWER: Controlling the power of the codec TWL4030_CODEC_RES_APLL: For APLL The vibra driver is not part of this series. I have also included a patch, which changes the board files for those, which in my knowledge uses the twl4030 codec as audio device. I might missed some boards... To-Do list: - revisit the error handling in twl4030-codec driver - add the actual vibra driver ;) - coexistence related fixes for the audio and vibra driver - move all audio related configuration from soc machine drivers to the board files (if any) --- Peter Ujfalusi (4): MFD: twl4030: add twl4030_codec MFD as a new child to the core OMAP: Platform support for twl4030_codec MFD ASoC: TWL4030: Only update the needed bits in *set_dai_sysclk ASoC: TWL4030: Driver registration via twl4030_codec MFD arch/arm/mach-omap2/board-3430sdp.c | 9 + arch/arm/mach-omap2/board-omap3beagle.c | 9 + arch/arm/mach-omap2/board-omap3evm.c | 9 + arch/arm/mach-omap2/board-omap3pandora.c | 9 + arch/arm/mach-omap2/board-overo.c | 9 + arch/arm/mach-omap2/board-zoom2.c | 9 + drivers/mfd/Kconfig | 13 ++ drivers/mfd/Makefile | 1 + drivers/mfd/twl4030-codec.c | 245 ++++++++++++++++++++++++++++ drivers/mfd/twl4030-core.c | 14 ++ include/linux/i2c/twl4030.h | 18 ++ include/linux/mfd/twl4030-codec.h | 261 ++++++++++++++++++++++++++++++ sound/soc/codecs/Kconfig | 2 +- sound/soc/codecs/twl4030.c | 225 ++++++++++++++++---------- sound/soc/codecs/twl4030.h | 242 +--------------------------- 15 files changed, 751 insertions(+), 324 deletions(-) create mode 100644 drivers/mfd/twl4030-codec.c create mode 100644 include/linux/mfd/twl4030-codec.h

[alsa-devel] Calling omap_pcm_prepare() results in BUG() on OMAP1
by Janusz Krzysztofik 21 Oct '09

21 Oct '09

Hi, After DMA burst mode has been introduced in sound/soc/omap/omap-pcm.c, omap_pcm_prepare() unconditionally calls: omap_set_dma_src_burst_mode(prtd->dma_ch, OMAP_DMA_DATA_BURST_16); omap_set_dma_dest_burst_mode(prtd->dma_ch, OMAP_DMA_DATA_BURST_16); AFAICS, current implementation of those two functions found in arch/arm/plat-ompa/dma.c doesn't support OMAP_DMA_DATA_BURST_16 on OMAP1 at all, so they both end with BUG() on that machine. That seems to result in ASoC being completely unusable, at least on my OMAP5910 based Amstrad Delta. Is calling BUG() for OMAP1 from those functions intentional? If not intentional, can those be corrected by simply putting break; before defalut:? If intentional, can those function calls be conditionally omited, at least for OMAP1510, in sound/soc/omap/omap-pcm.c? Thanks, Janusz

[alsa-devel] snd-hda-intel , changing the model option
by Colin Kincaid Williams 21 Oct '09

21 Oct '09

Hello, I'm trying to get my sound working and was wondering: Is there is a way to change the model option without restarting my computer? I tried editing the /etc/modprobe.d/alsa-base.conf file, and then restarting alsa with /etc/init.d/alsa-utils restart 0 , however I do not think the change is taking place. I used the alsa-info.sh script to determine if the change took place however it appears that the card has the same model name as when the machine booted. Best, Colin Williams

[alsa-devel] dev_* output functions and ASoC codecs
by Mike Frysinger 20 Oct '09

20 Oct '09

am i doing something wrong or are the dev_* output functions kind of useless with ASoC codecs ? it seems like the error output is prefixed by the generic "soc-audio" but no info related to the exact codec is included. as an example, the typical behavior is for the machine driver to call platform_device_alloc("soc-audio", -1). this struct device is then passed down to the relevant subsystem driver register/probe (i2c/spi/etc...) to the codec driver. these functions typically then set the snd_soc_codec's dev member to the allocated platform device. which means the snd_soc_codec's name member isnt included in decoding. so now any dev_* output in the codec driver looks like: soc-audio soc-audio: some message if there are multiple codecs, things obviously fall apart quickly. the question is how to address this. werent there snd_* output funcs before ? or are those now deprecated/dead ? or perhaps we should encourage people to stop doing platform_device_alloc("soc-audio") and start doing platform_device_alloc(snd_soc_card.name) ? also, there seems to be a semi-common bug in the codec/machine drivers where they dont actually initialize the dev member. perhaps it's time to upgrade the snd_soc_register_codec() check from a KERN_WARNING to a BUG_ON() ? clearly the current warning isnt getting its message through ... -mike

[alsa-devel] alsa buffer underrun
by 邱昇譽 20 Oct '09

20 Oct '09

Dear Alsa developers: I enconter a problem about alsa buffer underrun, and have no idea how to solve it. It's great if you can spent a little of your spare time to read this. Thanks. Our CPU, (a arm processor running at 162Mhz) using I2S to communicate with codec. The i2s hardware is simply a FIFO which generates an interrupt when the FIFO data is below the programed watermark(and relevant bit in status register will be set), then we re-fill data into FIFO in interrupt handler the interrupt handler code fragment will like this static irqreturn_t dw_tdm_handler(int irq, void *data) { struct dw_tdm_dev *dev = (struct dw_tdm_dev *)data; struct platform_device *pdev = dev->pdev; struct snd_pcm_substream *substream = dev->substream; struct snd_pcm_runtime *runtime = substream->runtime; u16 *buf = (u16 *)runtime->dma_area; u32 status = dw_tdm_read_reg(TDM_INT_ STATUS); unsigned int bytes_remain = runtime->dma_bytes - dev->dma_pos; buf += dev->dma_pos / sizeof(u16); /* tx fifo is running low, reload new data for it */ if (status & TX_INT) { int i; unsigned int empty_banks = TX_EMPTY_BANKS(dw_tdm_read_reg(TDM_STATUS)); /* 2 FIFO lines each bank */ unsigned int bytes_to_write = empty_banks * 4; bytes_to_write = min(bytes_remain, bytes_to_write); dev_dbg(&pdev->dev, "dma_pos = %d\n", dev->dma_pos); dev_dbg(&pdev->dev, "hw_ptr = %d\n", frames_to_bytes(runtime, runtime->status->hw_ptr)); /* re-fill data, 1 sample contains 4 bytes */ for (i = 0; i < bytes_to_write / 4; i++) { dw_tdm_write_reg(TDM_TX_FIFO, *buf++); /* left channel */ dw_tdm_write_reg(TDM_TX_FIFO, *buf++); /* right channel */ } dev->dma_pos += bytes_to_write; if (bytes_remain == bytes_to_write) dev->dma_pos = 0; } /* rx fifo is running full, consume data from it */ if (status & RX_INT) { /* TODO */ } dev_dbg(&pdev->dev, "period elapsed\n"); snd_pcm_period_elapsed(substream); /* clear interupt status */ dw_tdm_write_reg(TDM_INT_CLR, status); return IRQ_HANDLED; } This runs into buffer underflow problem, when I use aplay to play a wav file, it seems user-space process doesn't accquire any cpu time, after out i2s h/w start to work(, and generate interrupts) output look like below: (strings in <> is my comments) # aplay /1.wav Playing WAVE '/1.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo snd_pcm_lib_write1: avail = 8160 <aplay start to fill buffer> snd_pcm_lib_write1: avail = 7904 snd_pcm_lib_write1: avail = 7648 snd_pcm_lib_write1: avail = 7392 snd_pcm_lib_write1: avail = 7136 snd_pcm_lib_write1: avail = 6880 snd_pcm_lib_write1: avail = 6624 snd_pcm_lib_write1: avail = 6368 snd_pcm_lib_write1: avail = 6112 snd_pcm_lib_write1: avail = 5856 snd_pcm_lib_write1: avail = 5600 snd_pcm_lib_write1: avail = 5344 snd_pcm_lib_write1: avail = 5088 snd_pcm_lib_write1: avail = 4832 snd_pcm_lib_write1: avail = 4576 snd_pcm_lib_write1: avail = 4320 snd_pcm_lib_write1: avail = 4064 snd_pcm_lib_write1: avail = 3808 snd_pcm_lib_write1: avail = 3552 snd_pcm_lib_write1: avail = 3296 snd_pcm_lib_write1: avail = 3040 snd_pcm_lib_write1: avail = 2784 snd_pcm_lib_write1: avail = 2528 snd_pcm_lib_write1: avail = 2272 snd_pcm_lib_write1: avail = 2016 snd_pcm_lib_write1: avail = 1760 snd_pcm_lib_write1: avail = 1504 snd_pcm_lib_write1: avail = 1248 snd_pcm_lib_write1: avail = 992 snd_pcm_lib_write1: avail = 736 snd_pcm_lib_write1: avail = 480 snd_pcm_lib_write1: avail = 224 snd_pcm_lib_write1: avail = 0 <write completed, trigger pcm stream> <i2s h/w start to work, and consume all the buffers, in this period, aplay has no chance to re-fill buffer, and underrun occurs> underrun!!!

The problem is, ALSA and HDMI each has their default channel mapping, which unfortunately disagree. All the driver could do is to tell hardware about the required remapping info.

Definitely. HDMI monitors are smart devices and can behave slightly different. I've also experienced some weird HDMI monitor behaviors. Thanks, Fengguang

[alsa-devel] problems in getting rid of set_xfer_align
by Kai Vehmanen 19 Oct '09

19 Oct '09

Hello all, here's one problem that I stumbled on with the deprecated snd_pcm_sw_params_set_xfer_align() function. I'm not sure if anything needs to be done to this, but at least FYI for other app developers that might hit the same issue. In short, ecasound-2.7.0 was just released, and as one of the last commits, I dropped the call to snd_pcm_sw_params_set_xfer_align() as it has been deprecated since early 2008 in ALSA. Previously Ecasound had always set the xfer_align to 1. Anyways, right after the release I got an error report (from Pierre, cc'ed) about bad glitches in audio with the new release, and the problem now appears to be deprecation of set_xfer_align. To summarize: - app relies on xfer_align=1, and has previously set it explicitly - in kernels before 2.6.25, the xfer_align is initialized to period_size in pcm_native.c and to 1 in pcm_oss.c; but in 2.6.25 the field was removed altogether: http://git.alsa-project.org/?p=alsa-kernel.git;a=commit;h=d948035a928400ae1… - similar change was done to alsa-lib 1.0.16: http://git.alsa-project.org/?p=alsa-lib.git;a=commit;h=cf15e49d8460d9b56005… Now the problematic combination is: - new application (not anymore calling set_xfer_align()) - old alsa-lib and kernel (still initializing xfer_size) - application used with an ALSA PCM that is strict about what period-sizes can be used (e.g. in the specific case we found out, ALSA PCM wouldn't accept a power-of-two period size) This is common enough that some workaround is needed in apps, an in Ecasound's case case, I'll add some ifdef-magic to 2.7.1 so that xfer_align is still set if compiled against an older alsa-lib. That should cover majority of the cases...

[alsa-devel] [PATCH 0/8] RX-51 audio drivers
by Eduardo Valentin 19 Oct '09

19 Oct '09

Hello everyone, Here is a patch series with most of audio support for RX51. Basically it includes asoc machine driver for rx51, tpa6130a2 amplifier driver (asoc version), board file configuration and setup and the sidetone feature of mcbsp. On top of that, there are few patches to use regulator framework to control vmmc2. This series is based on linux-omap. So basically after applying it, you can boot the device and have sound support. Even though this patches were tested using linux-omap, the series is applicable on top of sound-2.6 tree as well. Please review. And as usual, comments are welcome.

[alsa-devel] Problems with newest alsa driver on 2.6.30 kernel - unknown symbols
by Christian Steffen 19 Oct '09

19 Oct '09

Hi there, while an older version of alsa drivers is working fine with my kernel 2.6.30, the newly compiled modules can't be inserted properly. I compiled snd-had-intel modules for my kernel 2.6.30 and tried to insert/start them. dmesg returns me: [ 106.209451] snd_hda_codec: Unknown symbol __snd_printk [ 106.210340] snd_hda_codec: Unknown symbol snd_hwdep_new [ 106.212211] snd_hda_codec: disagrees about version of symbol snd_pcm_hw_constraint_step [ 106.212217] snd_hda_codec: Unknown symbol snd_pcm_hw_constraint_step Any idea? Thanks, Christian

[alsa-devel] Questions on locking, snd-usb-caiaq
by Mark Hills 18 Oct '09

18 Oct '09

I fixed some race issues in snd-usb-caiaq, but have some questions on the interface between the driver and ALSA. First fix is a lock in pointer(), which caused snd_pcm_update_hw_ptr_pos() to report an out of range buffer position (even though it was sucessfully corrected to zero). Second is a lock as part of trigger(). On testing, this appears to fix an issue where white noise could sometimes be transferred by the driver. According to the documentation, trigger() and pointer() are called with local interrupts disabled. This means they should really be non-irqsave locks? (http://www.alsa-project.org/~tiwai/writing-an-alsa-driver/ch05s08.html) Even for callbacks documented as atomic, if read_completed() and write_completed() can be called at any time interrupts are enabled (eg. on another CPU) it seems that additional locking my be required. Candidates are: snd_usb_caiaq_substream_open snd_usb_caiaq_substream_close snd_usb_caiaq_pcm_hw_free snd_usb_caiaq_pcm_prepare Are there any guarantees on these functions which mean the lock is not required? To lock in prepare() would (I think) require demoting a spin_lock_irqsave() to a spin_lock() to send initialisation commands. If so, what is the best design for this?

[alsa-devel] How to close ALSA device nodes?
by Rémi Denis-Courmont 18 Oct '09

18 Oct '09

Hello, I'm getting a bug report against VLC media player whereby ALSA sound output stops working when the screensaver is inhibited. It turns out that VLC is leaking any file descriptor open through ALSA-lib into child processes. The exact same issue was already raised by mplayer... 6 years ago: http://www.mail-archive.com/alsa-devel@lists.sourceforge.net/msg06249.html In other cases (V4L, OSS, DVB, DVD, sockets, even regular files...), VLC would open the device nodes with O_CLOEXEC flag (if supported by kernel and libc) and fallback to setting FD_CLOEXEC via fcntl(). Then the descriptor is automatically, and in the earlier case, thread-safely, closed whenever VLC - forks and- execs. With ALSA-lib, I cannot figure any way to achieve that... From the earlier thread, I reckon that ALSA developers consider that this is an upper-layer issue. Maybe so, but then how is the upper-layer supposed to find which file descriptors ALSA-lib has opened - if any? Conversely, if ALSA- lib won't tell while file descriptors it is using, what could possibly be the use case for not closing those on exec? Best regards, -- Rémi Denis-Courmont http://www.remlab.net/

[alsa-devel] [patch] snd-pcsp: fix nforce_wa
by Stas Sergeev 17 Oct '09

17 Oct '09

Hi. In this commit: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdi… the nforce workaround (nforce_wa option) was broken, because the introduced "pointer_update" variable was forgotten to use. Also, the "ns" became u64 in some places and "long" in others, which is not the same, AFAIK. I revert that to u64-everywhere. Also, the log says: --- With the callback mode HRTIMER_CB_IRQSAFE_UNLOCK, the start of the stream with zero delay doesn't work. --- but the attached patch, that reverts to the "zero-delay start", works for me... So, while I like the cleanups made, I wonder what was the reason behind that changes? How can I reproduce the breakage of the zero-delay start? Oh, and it would be nice to CC me the changes in that driver, if possible. :)

[alsa-devel] [PATCH] Fix codec_dai->ops NULL pointer bug for AC97 codec dai in soc-core
by Barry Song 16 Oct '09

16 Oct '09

AC97 codec DAIs don't register themselves eg.stac9766, wm9712, wm9713, wm9705.c, ad1980, then it loses to the chance to be given a null_dai_ops in snd_soc_register_dai if they have no ops. When functions like soc_pcm_open, soc_pcm_hw_params etc. access the ops field in these DAIs, panic will happen.

[alsa-devel] How can i contribute a new AsoC codec driver for the CS42L51 ?
by Eduardo Tagle 16 Oct '09

16 Oct '09

Just forgive me... I am new to this world of mailing-lists, so let me explain... I have written an ASoC codec driver for the Cirrus Logic CS42L51 audio Codec. It was just based on the publicly available datasheet from Cirrus Website. I really would like to know how to submit it to be included in the official ASoC source tree. I have tested it as much as possible, and seems to work reliably. What are the steps required to follow to submit this new ASoC driver ? Thanks in advance, Eduardo

[alsa-devel] beeps with incorrect frequency / volume
by Sébastien Hinderer 16 Oct '09

16 Oct '09

Dear ALSA Developers, The sound card of my laptop is a HDA Intel, chip Intel G45 DEVCTG The PC beeps do not work correctly. One problem is that the frequency of the beeps one can hear does not correspond to the required frequency. For instane the command beep 440 produces a beep whose frequency is not 440Hz The second problem is that, although there is a PC beep control provided in alsamixer, the control is not taken into account: the beep is loud no matter how the control is set. I think this problem has already been reported but can't find it in the bug tracking system. Could someone please help and tell me whether the problem can e solved or not and, if it can, how. Many thanks in advance for any help, Sébastien.

[alsa-devel] [PATCH - try3] ASoC: Codec driver for Texas Instruments tlv320dac33 codec
by Peter Ujfalusi 15 Oct '09

15 Oct '09

Driver for Texas Instruments TLV320DAC33 (SLAS546) low power stereo audio DAC. TLV320DAC33 is a stereo audio codec with integrated 24KB FIFO for low power audio playback. The digital interface can use I2S, DSP (A or B), Right and Left justified formats. DAC33 has stereo analog input, which can be bypassed to the analog outputs. Regarding to the internal 24KB FIFO the driver implements 'FIFO bypass' mode (default) and nSample mode (FIFO is in use). a) In 'FIFO bypass' mode the internal FIFO is not in use, the codec is working synchronously as a normal codec (it needs constant stream of data on the digital interface). b) The nSample mode implementation uses one interrupt line from DAC33 to the host: Alarm threshold is set to 10ms of audio data (limit by the driver implementation). DAC33 will signal an interrupt, when the FIFO level goes under the Alarm threshold. The host will write to nSample register a value (number of stereo samples), to tell DAC33 how many samples it should read in a burst from the host. When the DAC33 received the number of samples, it disables the clocks on the I2S bus. When the FIFO use again goes under the Alarm threshold, DAC33 signals the host with an interrupt, and the process is repeated. Signed-off-by: Peter Ujfalusi <peter.ujfalusi(a)nokia.com> --- Hello, I'll hope that I got it right at this time, one thing that I'm not sure is the hard power handling changes (SND_SOC_BIAS_OFF, and related things). Changes since try2: - dac33_write_locked simplified (no duplicated code with dac33_write) - No unneeded casts - hard power handling changed - Interrupt handling is changed a bit (masking all interrupts from dac33 when the state is FLUSH - the needed IRQ will be unmasked when the next stream is starting) - nSample controls added conditionally - workqueue is created only, if we have valid IRQ number - snd_soc_register_codec and snd_soc_register_dai moved as the last thing in dac33_i2c_probe function. include/sound/tlv320dac33-plat.h | 20 + sound/soc/codecs/Kconfig | 4 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/tlv320dac33.c | 1237 ++++++++++++++++++++++++++++++++++++++ sound/soc/codecs/tlv320dac33.h | 267 ++++++++ 5 files changed, 1530 insertions(+), 0 deletions(-) create mode 100644 include/sound/tlv320dac33-plat.h create mode 100644 sound/soc/codecs/tlv320dac33.c create mode 100644 sound/soc/codecs/tlv320dac33.h diff --git a/include/sound/tlv320dac33-plat.h b/include/sound/tlv320dac33-plat.h new file mode 100644 index 0000000..5858d06 --- /dev/null +++ b/include/sound/tlv320dac33-plat.h @@ -0,0 +1,20 @@ +/* + * Platform header for Texas Instruments TLV320DAC33 codec driver + * + * Author: Peter Ujfalusi <peter.ujfalusi(a)nokia.com> + * + * Copyright: (C) 2009 Nokia Corporation + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + */ + +#ifndef __TLV320DAC33_PLAT_H +#define __TLV320DAC33_PLAT_H + +struct tlv320dac33_platform_data { + int power_gpio; +}; + +#endif /* __TLV320DAC33_PLAT_H */ diff --git a/sound/soc/codecs/Kconfig b/sound/soc/codecs/Kconfig index fab01c9..49bab93 100644 --- a/sound/soc/codecs/Kconfig +++ b/sound/soc/codecs/Kconfig @@ -29,6 +29,7 @@ config SND_SOC_ALL_CODECS select SND_SOC_TLV320AIC23 if I2C select SND_SOC_TLV320AIC26 if SPI_MASTER select SND_SOC_TLV320AIC3X if I2C + select SND_SOC_TLV320DAC33 if I2C select SND_SOC_TPA6130A2 if I2C select SND_SOC_TWL4030 if TWL4030_CORE select SND_SOC_UDA134X @@ -142,6 +143,9 @@ config SND_SOC_TLV320AIC26 config SND_SOC_TLV320AIC3X tristate +config SND_SOC_TLV320DAC33 + tristate + config SND_SOC_TWL4030 tristate diff --git a/sound/soc/codecs/Makefile b/sound/soc/codecs/Makefile index 2f14391..8f519ee 100644 --- a/sound/soc/codecs/Makefile +++ b/sound/soc/codecs/Makefile @@ -17,6 +17,7 @@ snd-soc-stac9766-objs := stac9766.o snd-soc-tlv320aic23-objs := tlv320aic23.o snd-soc-tlv320aic26-objs := tlv320aic26.o snd-soc-tlv320aic3x-objs := tlv320aic3x.o +snd-soc-tlv320dac33-objs := tlv320dac33.o snd-soc-twl4030-objs := twl4030.o snd-soc-uda134x-objs := uda134x.o snd-soc-uda1380-objs := uda1380.o @@ -70,6 +71,7 @@ obj-$(CONFIG_SND_SOC_STAC9766) += snd-soc-stac9766.o obj-$(CONFIG_SND_SOC_TLV320AIC23) += snd-soc-tlv320aic23.o obj-$(CONFIG_SND_SOC_TLV320AIC26) += snd-soc-tlv320aic26.o obj-$(CONFIG_SND_SOC_TLV320AIC3X) += snd-soc-tlv320aic3x.o +obj-$(CONFIG_SND_SOC_TLV320DAC33) += snd-soc-tlv320dac33.o obj-$(CONFIG_SND_SOC_TWL4030) += snd-soc-twl4030.o obj-$(CONFIG_SND_SOC_UDA134X) += snd-soc-uda134x.o obj-$(CONFIG_SND_SOC_UDA1380) += snd-soc-uda1380.o diff --git a/sound/soc/codecs/tlv320dac33.c b/sound/soc/codecs/tlv320dac33.c new file mode 100644 index 0000000..3ca8934 --- /dev/null +++ b/sound/soc/codecs/tlv320dac33.c @@ -0,0 +1,1237 @@ +/* + * ALSA SoC Texas Instruments TLV320DAC33 codec driver + * + * Author: Peter Ujfalusi <peter.ujfalusi(a)nokia.com> + * + * Copyright: (C) 2009 Nokia Corporation + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + * + * This program is distributed in the hope that it will be useful, but + * WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

[alsa-devel] HD-Audio Codec ALC888: Realtek Defined Registers and Digital Microphone
by Sebastian Konopka 15 Oct '09

15 Oct '09

Hello everybody on alsa-devel, I'm adding a new model to the patch_realtek.c file that supports all features my alc888-codec together with the laptop hardware offers. Everything works fine and can be used through alsa, except two things, because I did not find any usable information on them: 1. My laptop has an built-in digital microphone, that is connected to this codec according to the information I can get when using windows. The ALC888 datasheet shows that there are pins for digital microphone support. Thus I assume that they are used for the microphone. Those pins are share their functionality with GPIO pins: GPIO0/DMIC-CLK and GPIO1/DMIC-DATA. Unfortunally the datasheet does not provide further information on how to switch between GPIO and DMIC mode of those pins. Furthermore there is no information where the digital data can be found and how to transfer them over the HDA-Bus to the application. Does anybody have additional information on how to use digital microphones on realtek codecs? 2. Perhaps enabling the digital microphone is related to the so-called "Realtek Defined Registers" that can be found on NID=0x20 as processing coefficients. Furthermore the alc888 supports additional features like equalizer or echo-cancellation, etc. that can be controlled by these registers, as I suppose. Does anybody have information how what these registers and their contents mean? The datasheet does not provide any information. I hope you can help me. Sebsatian Konopka

[alsa-devel] Issue with creative Xfi PCIe ca0110-IBG
by Guillem Solà 15 Oct '09

15 Oct '09

Hi, I have a Creative XFi PCIe with ca0110-IBG chip. It's primary use is audio input for streaming on a brand new Dell server with RHEL. I have been testing latest kernel 2.6.31 through it's releases candidates and the card stoped working on 2.6.31-rc6, so now I'm stuck at 2.6.31-rc5. With rc5 I made a 2 weeks test and it went flawlessly. There's another guy who referenced this issue on http://mailman.alsa-project.org/pipermail/alsa-devel/2009-September/020876.… and Takashi Iwai said that there is a communication error between the codec and the controller. Any workaround? Is there a bug created related to this issue? I tried to "extract" the alsa-driver on 2.6.31-rc5 and install it 2.6.31 final without success. Also tried to get old snapshots from alsa-driver and alsa-kmirror but I cannot compile them. Any place where get some info about how to create my output from alsa-info: http://www.alsa-project.org/db/?f=09087914dfdd85a07dca432cf71a9626b4fc4251 regards, Guillem Solà

[alsa-devel] [PATCH - try2] ASoC: Codec driver for Texas Instruments tlv320dac33 codec
by Peter Ujfalusi 15 Oct '09

15 Oct '09

Driver for Texas Instruments TLV320DAC33 (SLAS546) low power stereo audio DAC. TLV320DAC33 is a stereo audio codec with integrated 24KB FIFO for low power audio playback. The digital interface can use I2S, DSP (A or B), Right and Left justified formats. DAC33 has stereo analog input, which can be bypassed to the analog outputs. Regarding to the internal 24KB FIFO the driver implements 'FIFO bypass' mode (default) and nSample mode (FIFO is in use). a) In 'FIFO bypass' mode the internal FIFO is not in use, the codec is working synchronously as a normal codec (it needs constant stream of data on the digital interface). b) The nSample mode implementation uses one interrupt line from DAC33 to the host: Alarm threshold is set to 10ms of audio data (limit by the driver implementation). DAC33 will signal an interrupt, when the FIFO level goes under the Alarm threshold. The host will write to nSample register a value (number of stereo samples), to tell DAC33 how many samples it should read in a burst from the host. When the DAC33 received the number of samples, it disables the clocks on the I2S bus. When the FIFO use again goes under the Alarm threshold, DAC33 signals the host with an interrupt, and the process is repeated. Signed-off-by: Peter Ujfalusi <peter.ujfalusi(a)nokia.com> --- I think I have addressed all the comments given for the first series. I might have missed something, but in short: - Handling of mutex is reworked, so it is not taken for all I2C accesses, but still protects the chip_power variable. - nsample_switch handling changed - IRQ handling reworked - Handling of the hard and soft power states are cleaner - definitions are namespeced - Some generic cleanups include/sound/tlv320dac33-plat.h | 20 + sound/soc/codecs/Kconfig | 4 + sound/soc/codecs/Makefile | 2 + sound/soc/codecs/tlv320dac33.c | 1235 ++++++++++++++++++++++++++++++++++++++ sound/soc/codecs/tlv320dac33.h | 267 ++++++++ 5 files changed, 1528 insertions(+), 0 deletions(-) create mode 100644 include/sound/tlv320dac33-plat.h create mode 100644 sound/soc/codecs/tlv320dac33.c create mode 100644 sound/soc/codecs/tlv320dac33.h diff --git a/include/sound/tlv320dac33-plat.h b/include/sound/tlv320dac33-plat.h new file mode 100644 index 0000000..5858d06 --- /dev/null +++ b/include/sound/tlv320dac33-plat.h @@ -0,0 +1,20 @@ +/* + * Platform header for Texas Instruments TLV320DAC33 codec driver + * + * Author: Peter Ujfalusi <peter.ujfalusi(a)nokia.com> + * + * Copyright: (C) 2009 Nokia Corporation + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + */ + +#ifndef __TLV320DAC33_PLAT_H +#define __TLV320DAC33_PLAT_H + +struct tlv320dac33_platform_data { + int power_gpio; +}; + +#endif /* __TLV320DAC33_PLAT_H */ diff --git a/sound/soc/codecs/Kconfig b/sound/soc/codecs/Kconfig index fab01c9..49bab93 100644 --- a/sound/soc/codecs/Kconfig +++ b/sound/soc/codecs/Kconfig @@ -29,6 +29,7 @@ config SND_SOC_ALL_CODECS select SND_SOC_TLV320AIC23 if I2C select SND_SOC_TLV320AIC26 if SPI_MASTER select SND_SOC_TLV320AIC3X if I2C + select SND_SOC_TLV320DAC33 if I2C select SND_SOC_TPA6130A2 if I2C select SND_SOC_TWL4030 if TWL4030_CORE select SND_SOC_UDA134X @@ -142,6 +143,9 @@ config SND_SOC_TLV320AIC26 config SND_SOC_TLV320AIC3X tristate +config SND_SOC_TLV320DAC33 + tristate + config SND_SOC_TWL4030 tristate diff --git a/sound/soc/codecs/Makefile b/sound/soc/codecs/Makefile index 2f14391..8f519ee 100644 --- a/sound/soc/codecs/Makefile +++ b/sound/soc/codecs/Makefile @@ -17,6 +17,7 @@ snd-soc-stac9766-objs := stac9766.o snd-soc-tlv320aic23-objs := tlv320aic23.o snd-soc-tlv320aic26-objs := tlv320aic26.o snd-soc-tlv320aic3x-objs := tlv320aic3x.o +snd-soc-tlv320dac33-objs := tlv320dac33.o snd-soc-twl4030-objs := twl4030.o snd-soc-uda134x-objs := uda134x.o snd-soc-uda1380-objs := uda1380.o @@ -70,6 +71,7 @@ obj-$(CONFIG_SND_SOC_STAC9766) += snd-soc-stac9766.o obj-$(CONFIG_SND_SOC_TLV320AIC23) += snd-soc-tlv320aic23.o obj-$(CONFIG_SND_SOC_TLV320AIC26) += snd-soc-tlv320aic26.o obj-$(CONFIG_SND_SOC_TLV320AIC3X) += snd-soc-tlv320aic3x.o +obj-$(CONFIG_SND_SOC_TLV320DAC33) += snd-soc-tlv320dac33.o obj-$(CONFIG_SND_SOC_TWL4030) += snd-soc-twl4030.o obj-$(CONFIG_SND_SOC_UDA134X) += snd-soc-uda134x.o obj-$(CONFIG_SND_SOC_UDA1380) += snd-soc-uda1380.o diff --git a/sound/soc/codecs/tlv320dac33.c b/sound/soc/codecs/tlv320dac33.c new file mode 100644 index 0000000..a28b98a --- /dev/null +++ b/sound/soc/codecs/tlv320dac33.c @@ -0,0 +1,1235 @@ +/* + * ALSA SoC Texas Instruments TLV320DAC33 codec driver + * + * Author: Peter Ujfalusi <peter.ujfalusi(a)nokia.com> + * + * Copyright: (C) 2009 Nokia Corporation + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License version 2 as + * published by the Free Software Foundation. + * + * This program is distributed in the hope that it will be useful, but + * WITHOUT ANY WARRANTY; without even the implied warranty of + * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

[alsa-devel] [PATCHv2 5/7] ASoC: TWL6030: Add support for low-power mode
by Lopez Cruz, Misael 14 Oct '09

14 Oct '09

TWL6030 codec supports two power modes: low-power and high performance. In low-power mode, headset downlink must be the only path enabled and components in that path (headset DAC and driver) should be in that mode too. In this mode, codec can stream audio at 44.1 and 48 kHz if sys clock from CLK32K is configured to 17.64 and 19.2 MHz using low-power PLL, respectively. In high-performance mode, codec can only work at 19.2 MHz from high-performance PLL. All paths supported in the codec can be used but audio can be streamed only at 48 kHz.

[alsa-devel] Which transfer mode to use
by Till Crueger 14 Oct '09

14 Oct '09

Hi, First of all, I am fairly new to this list, as well as sound development. So if this list is the wrong place for this question, it would be nice if you could point me in the right direction. I am trying to use ALSA in my OCaml [1] programms. As far as I could see there are no well documented bindings to ALSA for this language, so I am stuck with writing my own bindings. I have gotten to the point where I can open a pcm device with a minimal configuration space on my desktop as well as on my laptop. However I am not sure which transfer mode to use, since it is hard to see for me, what the advantages and disadvantages would be. Here is what I have found out so far. 1. Asynchronous callback: This method seems to be the best explained by all the tutorials I could find, so I am guessing this is the best choice for audio applications. However for my purpose this seems hard to do, since the thread which contains the callback must never enter the OCaml side of the wrapper. This constraint is due to the OCaml garbage collector, which AFAIK would be messed up severely. So to use this method I would have to write an extra buffer in the C side, to which I write the data from OCaml. Depending on the way this buffer is set up -- I was thinking of using a linked list to contain all the single packets -- I would have to keep track what part of the usage of this buffer to be able to synchronise anything to the sound. Not the best choice I as far as I can see. 2. read/write: So far this seems the best choice. This way I could probably rewrite the asynchronous callback method on the OCaml side. For this however I would have to figure out after each polling, how much data can be written. I had a look at the API documentation and it seems ALSA provides function to get this information. However when I had a look at the example sine-wave generator [2], those functions were only used by the mmap method. So the question would be if this information could still be provided when using the read/write method. 3. mmap: During the research I did for this project I found some posts on the portaudio list, that said this method could not be used with all soundcards. Also I would have to figure out if the memory layout of the data passed from the OCaml side is at all compatible to this method. If it is incompatible the use of mmap does not seem to make sense at all. So far this are the points I have gathered to help me make a choice. As you can see I already have a clear preference, but at this point I am still not quite sure. I also found some links that hinted at other issues that would have to be taken into consideration. For example I found some concerns about differences in lattency between these three methods. So what is your opinion on this. Do you think reintroducing the async. callback on the OCaml side would be a good idea, or would you rather use the second buffer that is accesible from the OCaml side. As I said, I haven't done any real sound development, so I am really new to this. Thanks for your help, Till [1] OCaml is a functional language developed by Inria. http://caml.inria.fr/ [2] http://www.alsa-project.org/alsa-doc/alsa-lib/_2test_2pcm_8c-example.html
