[alsa-devel] [PATCH 0/8] ASoC: TWL4030: DAPM implementation for outputs (playback)
by Peter Ujfalusi 09 Dec '08

09 Dec '08

Hello, This series of patches adds DAPM implementation for all outputs found on TWL. The design allows one to configure all outputs independently from each other, since the internal routing of TWL actually treats them individually. The pre-DAC routings can be configured in the board specific files of needed. I have sent a patch which has added this to the codec driver. Based on the output routing selections all the corresponding DAC and analog PGA on the chain will be powered on. --- Peter Ujfalusi (8): ASoC: TWL4030: Correct DAPM_DAC with power control ASoC: TWL4030: Add Analog PGA control switch to DAPM ASoC: TWL4030: Add DAPM event handler for output MUX selection ASoC: TWL4030: DAPM mapping of the Earpiece output ASoC: TWL4030: DAPM mapping of the PreDriv outputs ASoC: TWL4030: DAPM mapping of the Headset outputs ASoC: TWL4030: DAPM mapping of the Carkit outputs ASoC: TWL4030: DAPM mapping of the Handsfree outputs sound/soc/codecs/twl4030.c | 248 +++++++++++++++++++++++++++++++++++++++++++- 1 files changed, 243 insertions(+), 5 deletions(-)

[alsa-devel] ASoC: hook for codec control updates and clock controls
by Daniel Mack 08 Dec '08

08 Dec '08

Hi, Codecs like the tlv320aic3x family have soft volume controls to smoothly drive up and down mixer elements in order to prevent clicks and pops. In fact, most of the controls on this chip are implemented as such. For the mixers to work, however, the I2S input clock is needed which is currently only true when the DAC/ACD elements are active but not when the chip is just operating as an analog mixer. To allow this functionality, the I2S clock must be present for a short period after each volume control update to the codec and disabled again after some milliseconds. It should, however, not be enabled if it's already running and of course, it must not be disabled if the ADC/DAC is still running. Adding a hook to struct snd_soc_codec which is called from snd_soc_update_bits() isn't a big deal, but the problem is the abstraction layers in this case - for good reasons, the cpu_dai is not accessible from the codec dai. Or did I miss a link? Is there a sane way to address this problem? Thanks and best regards, Daniel

[alsa-devel] [patch] alsa-utils check if __USE_BSD is defined before compiling "BSD functions"
by Hans-Christian Egtvedt 08 Dec '08

08 Dec '08

Hi, Another bug/issue I tripped over when compiling alsa-utils in an environment using uClibc to supply the C library functions. Here I have enabled some old BSD style functions. The attached patch will honor them if they are enabled. Without this patch I get a redefined error during compile. -- Best regards, Hans-Christian Egtvedt

[alsa-devel] HDA: CLFE DAC on ALC889 (Acer Aspire 8930G)
by Hector Martin 07 Dec '08

07 Dec '08

I've been trying to get ALSA working with this laptop. So far the attached patch adds rear support to the existing 4930g model, and tries to add CLFE support. However, I haven't been able to get CLFE to work. I don't seem to get any audio through DACs/mixers other than the first two (front and rear). I can assign the CLFE output (pin 0x16) to the front or rear DAC and hear the front audio through the CLFE speakers. I can also force the front DAC (0x02) or rear DAC (0x03) to use the CLFE stream and hear it through the front or rear speakers, so the audio is getting to the codec. But either DACs 0x04 and 0x05 aren't working, or their associated mixers (0x0e and 0x0f) aren't passing through the audio, or the OUT pins don't like selections above 1. I've checked that they're unmuted and that the volumes are turned up on both. I've also tried the 0x25->0x26 DAC/mixer auxiliary pathway, which doesn't work either. Here's what the relevant NIDs correspond to: 0x02 - (normally) Front DAC 0x03 - (normally) Rear DAC 0x04 - (normally) CLFE DAC 0x05 - (presumably) side DAC (no side speakers) 0x0c - (normally) Front mixer 0x0d - (normally) Rear mixer 0x0e - (normally) CLFE mixer 0x0f - (presumably) side mixer 0x14 - Front speakers pin 0x15 - Headphones pin (also EAPD for speaker amp) 0x16 - CLFE speakers pin 0x1b - Rear speakers pin Here's what the codec graph looks like: http://marcansoft.com/transf/codec.png Any ideas? I'm pretty stumped here. Are there any other magic bits to enable the remaining DACs or mixers? -- Hector Martin (hector(a)marcansoft.com) Public Key: http://www.marcansoft.com/marcan.asc

Re: [alsa-devel] [Swfdec] Can't use Mozilla plugin or play video with 0.8.2 / 0.9.2
by Benjamin Otte 07 Dec '08

07 Dec '08

I think I know what this is. But I spent the best part of my breakfast wondering about it. I think using Pulse Audio might work around this problem, but I think it's a driver, configuration issue on the ALSA side or a misunderstanding of the API on my part, which is why I'm sending this to the ALSA list. So here's the problem: Swfdec uses ALSA in non-blocking mode and polls its file descriptor(s). Whenever the audio queue becomes empty enough that it's useful to render more audio, the file descriptor wakes up from the poll. This setting is apparently configurable using various hw params, however, Swfdec does not configure it and has been relying on the fact that the sound device picks proper defaults, thinking that a sound card with a small buffer will likely want to wake up more often than something like Pulse Audio's new design, which keeps a 2+ second buffer for the audio. It seems though that your sound card wakes up roughly whenever a new sample can be rendered, which is 44100 times per second (or more, as from your profile it looks like ALSA resamples the audio). This causes the whole rendering code inside Swfdec to run for every sample, which is so much overhead that it kills all your performance. My question to you ALSA people now is: Who's responsible for ensuring that the number of wakeups is sane? Should I do some configuring of the audio device and if so, what kind of configuration, or should ALSA be able to pick reasonable defaults for me?

The timing of capture and playback isn't synchronized, so you'll get often noisy outputs. I've worked on this driver yesterday, just did some clean up works. Hopefully I'll be able to fix the issue sometime later... thanks, Takashi

[alsa-devel] [PATCH] ASoC: Add support for OMAP3 Pandora
by Grazvydas Ignotas 04 Dec '08

04 Dec '08

This patch adds basic support for OMAP3 Pandora. Signed-off-by: Grazvydas Ignotas <notasas(a)gmail.com> --- I'm not sure if splitting DAPM and widgets was good idea, I can adjust if needed. The map is also not quite right, it says headphone jack is connected to TWL4030 codec OUTL and OUTR, but that is not really the case. It is connected to external DAC, and DAC is connected to OMAP. However DAC uses clock from TWL4030, so TWL needs to be active. I've basically done that connection to get event callback, where I can switch DAC and headphone amp on/off. sound/soc/omap/Kconfig | 8 + sound/soc/omap/Makefile | 2 + sound/soc/omap/omap3pandora.c | 293 +++++++++++++++++++++++++++++++++++++++++ 3 files changed, 303 insertions(+), 0 deletions(-) create mode 100644 sound/soc/omap/omap3pandora.c diff --git a/sound/soc/omap/Kconfig b/sound/soc/omap/Kconfig index da39f27..a7b1d77 100644 --- a/sound/soc/omap/Kconfig +++ b/sound/soc/omap/Kconfig @@ -46,3 +46,11 @@ config SND_OMAP_SOC_SDP3430 help Say Y if you want to add support for SoC audio on Texas Instruments SDP3430. + +config SND_OMAP_SOC_OMAP3_PANDORA + tristate "SoC Audio support for OMAP3 Pandora" + depends on TWL4030_CORE && SND_OMAP_SOC && MACH_OMAP3_PANDORA + select SND_OMAP_SOC_MCBSP + select SND_SOC_TWL4030 + help + Say Y if you want to add support for SoC audio on the OMAP3 Pandora. diff --git a/sound/soc/omap/Makefile b/sound/soc/omap/Makefile index 29cf3a8..76fedd9 100644 --- a/sound/soc/omap/Makefile +++ b/sound/soc/omap/Makefile @@ -11,9 +11,11 @@ snd-soc-osk5912-objs := osk5912.o snd-soc-overo-objs := overo.o snd-soc-omap2evm-objs := omap2evm.o snd-soc-sdp3430-objs := sdp3430.o +snd-soc-omap3pandora-objs := omap3pandora.o obj-$(CONFIG_SND_OMAP_SOC_N810) += snd-soc-n810.o obj-$(CONFIG_SND_OMAP_SOC_OSK5912) += snd-soc-osk5912.o obj-$(CONFIG_SND_OMAP_SOC_OVERO) += snd-soc-overo.o obj-$(CONFIG_MACH_OMAP2EVM) += snd-soc-omap2evm.o obj-$(CONFIG_SND_OMAP_SOC_SDP3430) += snd-soc-sdp3430.o +obj-$(CONFIG_SND_OMAP_SOC_OMAP3_PANDORA) += snd-soc-omap3pandora.o diff --git a/sound/soc/omap/omap3pandora.c b/sound/soc/omap/omap3pandora.c new file mode 100644 index 0000000..4f92877 --- /dev/null +++ b/sound/soc/omap/omap3pandora.c @@ -0,0 +1,293 @@ +/* + * omap3pandora.c -- SoC audio for Pandora Handheld Console + * + * Author: Gražvydas Ignotas <notasas(a)gmail.com> + * + * 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] question for the all-knowing - firewire audio hardware
by S. Aguinaga 04 Dec '08

04 Dec '08

Hello! I have a couple of machines connected to FireWire Motu devices (running OS X). We want to develop some new apps on linux and the only info I've found is: http://www.olafchrist.de/ieee1394/index.php, but its rather old and single device specific. Are there any other solutions available? Or are there other devices (firewire) that are supported by the ALSA project? Any info on this will be great!! // Sal

[alsa-devel] [PATCH] ALSA: Reduce stall detection timeout in riptide.c

Reduce the command timeout to 0.5sec. Should be enough to allow a working command interface but removes a RCU stall and slow resume on some revisions where the AC97 revision detection stalls in resume.

I'm not sure what this > means, however. Are these drivers, a kernel ... how do I try them? It's a linux kernel git tree. Ask other Ubuntu guys how to build your kernel. Or, use the alsa-driver snapshot tarball in the ftp directory above. You can install it just like the normal alsa-driver release tarball. Takashi

[alsa-devel] [PATCH] tlv320aic3x: headset/button press support
by Daniel Mack 03 Dec '08

03 Dec '08

Hi, This patch adds a function to setup headset and button press detection modes. Also, aic3x_headset_detected() returns the value from the current state's register rather than the interrupt cause flag so it works without an interrupt as well. Best regards, Daniel

[alsa-devel] [PATCH] ASoC: TWL4030: Add input selection and gain controls
by Grazvydas Ignotas 03 Dec '08

03 Dec '08

The TWL4030 codec device has two ADCs. Both of them can have several inputs routed to them, but TRM says that only one source can be selected for every ADC, even though every source has a dedicated bit in the registers. This patch adds input source controls. It modifies default register values to have no inputs selected and ADCs disabled. When some input is selected, control handlers enable apropriate input amplifier and ADC. If a microphone is selected, bias power is automatically enabled. When some input is deselected, unused chip parts are disabled. Microphone and line input recording tested on OMAP3 pandora board. Signed-off-by: Grazvydas Ignotas <notasas(a)gmail.com> --- Compared to my previous patch, I've changed "Microphone Boost" name to "Input Boost Volume", as it affects line inputs too. I thought that hiding this control for line-in was not a good idea, as it might still be useful for weak sources. "Capture" was also changed to "Input", as inputs can be also routed to outputs, not only recorded. sound/soc/codecs/twl4030.c | 177 +++++++++++++++++++++++++++++++++++++++++++- sound/soc/codecs/twl4030.h | 16 ++++ 2 files changed, 190 insertions(+), 3 deletions(-) diff --git a/sound/soc/codecs/twl4030.c b/sound/soc/codecs/twl4030.c index ffd5120..3c9fdf2 100644 --- a/sound/soc/codecs/twl4030.c +++ b/sound/soc/codecs/twl4030.c @@ -46,9 +46,9 @@ static const u8 twl4030_reg[TWL4030_CACHEREGNUM] = { 0xc3, /* REG_OPTION (0x2) */ 0x00, /* REG_UNKNOWN (0x3) */ 0x00, /* REG_MICBIAS_CTL (0x4) */ - 0x24, /* REG_ANAMICL (0x5) */ - 0x04, /* REG_ANAMICR (0x6) */ - 0x0a, /* REG_AVADC_CTL (0x7) */ + 0x20, /* REG_ANAMICL (0x5) */ + 0x00, /* REG_ANAMICR (0x6) */ + 0x00, /* REG_AVADC_CTL (0x7) */ 0x00, /* REG_ADCMICSEL (0x8) */ 0x00, /* REG_DIGMIXING (0x9) */ 0x0c, /* REG_ATXL1PGA (0xA) */ @@ -347,6 +347,162 @@ static int snd_soc_put_volsw_r2_twl4030(struct snd_kcontrol *kcontrol, return err;

[alsa-devel] [PATCH] ASoC: TWL4030: Add capture source selection and mic gain control
by Grazvydas Ignotas 02 Dec '08

02 Dec '08

The TWL4030 codec device has two ADCs. Both of them can have several inputs routed to them, but TRM says that only one source can be selected for every ADC, even though every source has a dedicated bit in the registers. This patch adds controls for capture source controls. When a microphone is selected, handlers automatically enable bias power (disable when deselected). The patch also adds microphone gain control. Microphone and line input recording tested on OMAP3 pandora board.

[alsa-devel] ASoC: TWL4030 codec: Multiple DAC nameing
by Peter Ujfalusi 02 Dec '08

02 Dec '08

Hello, Now I have some working prototype for the TWL4030 codec DAPM playback routing. But before I send the patches I want to clear out something: Since the TWL has four DACs and I want to map all of them, what would be the correct SND_SOC_DAPM_DAC naming for them? At the moment I have these: /* DACs */ SND_SOC_DAPM_DAC("DACR1", "Right Front Playback", TWL4030_REG_AVDAC_CTL, 0, 0), SND_SOC_DAPM_DAC("DACL1", "Left Front Playback", TWL4030_REG_AVDAC_CTL, 1, 0), SND_SOC_DAPM_DAC("DACR2", "Right Rear Playback", TWL4030_REG_AVDAC_CTL, 2, 0), SND_SOC_DAPM_DAC("DACL2", "Left Rear Playback", TWL4030_REG_AVDAC_CTL, 3, 0), Are these are OK, or should I just use "Right Playback" for both DACR1 and DACR2? Btw: the 'dynamic' routing and switching now works (no user visible power control for the DACs and APGAs) in a way, that if the output is configured to take the audio from one of the DAC, than the corresponding chain (APGA, DAC) will be powered on only. Thanks, Péter

[alsa-devel] (SoC) Does i.MX27's SSI work as I2S clock master?
by ngc＠drvlabo.jp 01 Dec '08

01 Dec '08

Hello, lists. Now I'm porting WM8728 driver with i.MX27ADS, based on Freescale's BSP kernel(2.6.22) and refering to ALSA SoC git repository. I'm connecting the WM8728 to the SSI2 controller via SSI-3 signal set. Then, my ADS board has altered: i.MX27 WM8728 --------------------- SSI3_CLK BCLKIN SSI3_FS LRCIN SSI3_TXDAT DIN TOUT/SSI2_MCLK MCLK Of course, I added some codes to configure GPIO pins as appropriate into board specific sources. Then, I'm trying to play sounds via WM8728 and have not hear any sounds yet. I checked SSI-3 signal set with an oscilloscope, no clock signal appears on SSI3_CLK. I tried the various SSI setting, I2S normal, I2S master, asychronous/synchronous, normal mode/network mode, ... But, I can't see clock signal, yet. I want to know an example setting to act i.MX' SSI as I2S clock master. Regards, -------------- NOGUCHI Hiroshi ngc(a)drvlabo.jp

[alsa-devel] Help with Creative's X-Fi drivers
by James Pearson 01 Dec '08

01 Dec '08

I know the ALSA team don't support Creative's X-Fi drivers, but maybe someone could help with this issue: I've managed to 'backport' Creative's recently GPL'd drivers to run on a CentOS4 kernel with ALSA 1.0.15 - the changes to the code were minor, but one thing I'm not sure about is, in ctpcm.c it has: static int ct_pcm_timer_stop(struct ct_atc_pcm *apcm) { unsigned long flags; CTDPF("%s is called\n", __func__); spin_lock_irqsave(&apcm->timer_lock, flags); apcm->stop_timer = 1; del_timer(&apcm->timer); spin_unlock_irqrestore(&apcm->timer_lock, flags); try_to_del_timer_sync(&apcm->timer); return 0; } The CentOS4/RHEL4 2.6.9 kernel doesn't have try_to_del_timer_sync() - so, should I replace it with del_timer() or del_timer_sync() ? I'm currently using del_timer_sync() - and the driver works (I get sound out the head phone jack) - is this OK? Thanks James Pearson

[alsa-devel] Restore state around suspend/resume
by Dan Nicholson 01 Dec '08

01 Dec '08

Hi, Currently, suspending the computer via pm-suspend (as done from HAL), causes the ALSA state to be stored and restored via alsactl. Here's what the hook looks like: http://cgit.freedesktop.org/pm-utils/tree/pm/sleep.d/65alsa Is this still necessary on recent kernels? Is there a list of drivers which properly maintain state across suspend/resume? We're trying to cut down on the amount of work done in userspace which slows down suspend cycles. Thanks. -- Dan -- To unsubscribe from this list: send the line "unsubscribe alsa-devel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

Hi, can you enable the sound debug options: CONFIG_SND_VERBOSE_PRINTK=y CONFIG_SND_DEBUG=y CONFIG_SND_DEBUG_VERSOSE=y (be warned it generates lots of log entries) and search for "send cmd ...failed" you will also find some "send cmd" lines containing timing statistics. Then try to reduce the timeoutvalue in sound/pci/riptide/riptide.c CMDIF_TIMEOUT to something near mintime/maxtime (it defaults to 5 sec [500000*10us]) If the error is hard to reproduce you might want to try this: --- a/sound/pci/riptide/riptide.c +++ b/sound/pci/riptide/riptide.c @@ -945,8 +945,8 @@ static int sendcmd(struct cmdif *cif, u32 flags, u32 cmd, u32 parm, errout: cif->errcnt++; spin_unlock_irqrestore(&cif->lock, irqflags); - snd_printdd - ("send cmd %d hw: 0x%x flag: 0x%x cmd: 0x%x parm: 0x%x ret: 0x%x 0x%x CMDE: %d DATF: %d failed %d\n", + snd_printk(KERN_ERR + "send cmd %d hw: 0x%x flag: 0x%x cmd: 0x%x parm: 0x%x ret: 0x%x 0x%x CMDE: %d DATF: %d failed %d\n", cif->cmdcnt, (int)((void *)&(cmdport->stat) - (void *)hwport), flags, cmd, parm, ret ? ret->retlongs[0] : 0, ret ? ret->retlongs[1] : 0, IS_CMDE(cmdport), IS_DATF(cmdport), and disable the SND_DEBUG stuff (less log spam but you see which commands are failing and together with the reduced CMDIF_TIMEOUT you also see which commands are stalling) Peter Am Freitag, den 28.11.2008, 07:48 +0100 schrieb Eric Sesterhenn: > Hi, > > Sometimes during bootup on this box i get a warning that resume took too long > (I have suspend testing enabled).

[alsa-devel] HDA Analyzer
by Jaroslav Kysela 28 Nov '08

28 Nov '08

Hi HDA developers, I am trying to write a small tool for control and analyze HDA codecs (something like more powerful GUI brother for Takashi's hda-verb). For rapid development, I chose python and pygtk2 gtk bindings. At this time, only basic things are implemented and not all widget types are supported in detail, but routing and volume control is implemented. If you are interested to check this preview and send me ideas to make this tool better, the code is available at URL bellow (or in alsa.git repo - see www.alsa-project.org). http://git.alsa-project.org/?p=alsa.git;a=tree;f=hda-analyzer Planned features: - support all widget types in detail - allow assign custom names to nodes for better orientation - raw verb r/w ops - save a text output of codec configuration for driver developers (maybe some diff) - run aplay or speaker-test directly from GUI - run arecord directly from GUI with some simple scope to analyze input - sysfs support for actual HDA driver Jaroslav ----- Jaroslav Kysela <perex(a)perex.cz> Linux Kernel Sound Maintainer ALSA Project, Red Hat, Inc.

[alsa-devel] simplest volume control possible
by John Kacur 28 Nov '08

28 Nov '08

I'm looking at the dapm.txt documentation, and I'm looking at the code in codecs like wm8753.c, and I'm thinking that all of this is tremendous overkill for the very simple codec I have. Basically I don't care about power, the thing can be powered on all the time. I put a one pulse on a gpio for volume up and a zero pulse on a gpio for volume down, 0 - 63 pulses though. Question, then, what would be an appropriate widget to use?

[alsa-devel] [PATCHv2 0/1] OMAP_TWL4030 SoC Audio driver.
by Stanley.Miao 27 Nov '08

27 Nov '08

Changes from v1: 1, change the name from omap-general to omap_twl4030. 2, proune off board related defines. 3, add a extended interface omap_twl4030_specific_init() to support some board specific features. If some board specific features are added into a board, for example, omap3evm board. we can create a new file omap3evm.c and define a funciton omap_twl4030_specific_init() in it, and select SND_OMAP_TWL4030_SPECIFIC in config SND_OMAP_SOC_OMAP3EVM.

This should all be one ASoC device, especially given that the fact that all the paths use the TWL4030 somehow. Have a look at how, eg, the neo1973 driver handles the bluetooth. For now there's not *particularly* sane support for multiple codecs. Does the DAC have any software control? If not it should be fairly straightforward to handle.

[alsa-devel] Alsa Driver Development - General Concepts
by karl＠lil-voodoo.co.uk 27 Nov '08

27 Nov '08

Hi, I've got a couple of audio/midi devices knocking around that I'd quite like to add ALSA support for (for use in Linux sequencers/DAWs) so I've been reading up on Linux device drivers and Alsa driver development. I do have a programming background but unfortunately, I'm a little confused on a couple of points and I was hoping someone wouldn't mind helping me out. I'm kind of basing my thoughts on the idea that I have a USB device which is not recognised by the kernel and does not expose a known midi interface (so requires a completely new Alsa driver?). The goal would be for this device to be usable in Linux midi sequencers. - How does the Alsa driver communicate with the hardware? Would I need to write a Kernel driver (e.g. a character device) for the Alsa driver to talk to? - Would my Alsa driver basically create a card instance and then a RawMidi component? I'm assuming the use of RawMidi would then allow applications to recognise the Alsa driver as a seemingly ordinary midi port??? Then implement _input_trigger() and _output_trigger() to exchange data with the application, whilst passing data to/from the kernel driver to talk to the hardware? Sorry if I'm way off base. I'm trying to get in on this thing to help spread some extra Linux love in music world. Many thanks.

Hi, is it possible to include Creative driver into alsa drivers package, so it will be available right after kernel installation without additional compiling? Besides, you can react faster to kernel changes and make driver compatible with latest kernels when necessary, if you include it.

[alsa-devel] floating point exception triggered by speaker-test on pc-speaker
by Alexander E. Patrakov 26 Nov '08

26 Nov '08

Hello, I have hit a strange bug. To reproduce: 1. Build snd-pcsp.ko. 2. alsamixer -c pcsp, set the base frequency to 37286 Hz 3. $ speaker-test -r 22050 -P 4 -D plughw:pcsp speaker-test 1.0.18 Playback device is plughw:pcsp Stream parameters are 22050Hz, S16_LE, 1 channels Using 16 octaves of pink noise Rate set to 22050Hz (requested 22050Hz) Buffer size range from 37 to 38756 Period size range from 18 to 19379 Using max buffer size 38756 Periods = 4 was set period_size = 0 was set buffer_size = 38756 0 - Front Left Floating point exception I.e., as you see, period size somehow became 0. While debugging this with printfs, I noticed that the interval for periods in snd_pcm_hw_param_set_near() starts with 4, but doesn't include it (i.e., is open). Also, I found that snd_interval_refine_first() and snd_interval_refine_last(), when given an open interval, refine it to something like (n n+1). This is obviously wrong, as there are no integer points in this interval. Changing i->max++ and i->min-- there to adjust the value by 2 did eliminate the floating point exception, but replaced it with "Unable to set nperiods 4 for playback: Invalid argument". So there must be something else also wrong, but I can't pinpoint it and give you a ready-made patch :( -- Alexander E. Patrakov

[alsa-devel] Query for running OSS application on ALSA
by Saxena, Anshuman 26 Nov '08

26 Nov '08

Hi, I have been using OSS drivers and applications. Now I have moved to ALSA SoC framework supported in the kernel. I have got the same OSS application running on this ALSA SoC framework but I have the following observation: When I run the OSS application to playback some audio through ALSA SoC framework, and I send CTRL+C signal to terminate the application, I see a delay of around 3-4 sec before the application really close. I traced and found out that it takes lot of time in snd_pcm_drain in pcm_native.c . But if I run some ALSA application, I do not see this delay in terminating the application. Is there some known issue with OSS emulation of ALSA SoC framework? I feel that some buffers are being drained out to the audio codec and hence this time is consumed. Is their some configuration for the buffer size? Can I directly stop the data transfer to codec and discard the remaining data? Your help is highly appreciated. Thanks and Regards, Anshuman

Hi All ... I am running Fedora 9 with 2.6.27.4 kernel. I have download and instaled ALSA 1.0.18. Card is EUROTECH INC CATALYST with Intel ATOM processor and Intel System Controler Hub US15W. Attached is output from alsa-info.sh and /proc/asound/card0. I have run bunch of different voice test but no sound on either output on this card. I have compile alsa library pcm test and run on this board no sound. I have activated and added some dignostic to hda controler code

I've been trying to check out the latest alsa-driver source to do some work on it. I followed the instructions at: http://www.alsa-project.org/main/index.php/GIT_Server#Occasional_Developers But when I cd alsa-drivers and gitcompile, it fails: make[1]: Entering directory `/homedirs/kamilner/Development/Workspace/alsa/alsa-driver/acore' copying file alsa-kernel/core/init.c patching file init.c Hunk #2 succeeded at 280 (offset 3 lines).

[alsa-devel] via82xx: unreliable audio, strange mixer behavior
by Forest Bond 25 Nov '08

25 Nov '08

Hi, I'm using snd-via82xx on an Ubuntu 8.04 system. alsa-info.sh output is here: http://www.alsa-project.org/db/?f=1c3d5570e7b57d4d2f79b964a323dd7b4efd7e78 Here are the symptoms: Audio goes away after a semi-random interval. Sometimes it returns after `modprobe -r snd-via82xx' followed by `modprobe snd-via82xx', but sometimes it seems to take a full reboot. This looks similar to: https://bugtrack.alsa-project.org/alsa-bug/view.php?id=3D3194 Some folks think that this kind of issue is triggered by audio volume being above a certain level. I'm not entirely sure if this is true, but I think it is. One time, I apparently triggered the issue by unplugging and replugging the audio cable from the mainboard during playback. Audio can be heard even when the PCM volume level is 0 (as told by alsamixer). The volume does get louder when I turn up that mixer control, but it never goes away entirely when I turn the volume to zero. Mute works as expected. This issue is impacting a significant project for me and my company. I'm willing to spend as much time as it takes to debug, and I'm fairly technical. I can also offer a bounty of some sort, if that interests anyone. Can anyone offer any input? Thanks, Forest -- Forest Bond http://www.alittletooquiet.net http://www.pytagsfs.org

[alsa-devel] [topic/asoc][PATCH 0/2] ASoC: OMAP: Add support for mono audio links in McBSP DAI (take #2)
by Jarkko Nikula 25 Nov '08

25 Nov '08

Hi Second version adding support for mono audio links in OMAP McBSP DAI. At this time, the channels_min is defined to 1 in omap-mcbsp.c and no hacks in machine drivers wanting to use mono link are required. If channel restrictions are required, then machine driver can use snd_pcm_hw_constraint_minmax. Now only N810 machine driver is affected since all other OMAP machine drivers are using TWL4030 or TLV320AIC23 codecs which all claim to support only 2 channels so the link remains always stereo even playing mono audio. -- Jarkko

[alsa-devel] [PATCH 0/9] ASoC: TWL4030: Add mixer controls for outputs
by Peter Ujfalusi 25 Nov '08

25 Nov '08

Hello, I have tried to clean up the changes that I have at the momnent. After the series you will have 'ultimate' control on how the audio is routed to the outputs of TWL. One can select the possible inputs (for the output) on all cahnnels. Also I have added gain (volume) controls, wherever it is possible, but they are working for both channels in case of stereo outputs. I tried to name the controls to match with the output's name, so you can easily tell which pin(s) the control will touch. The capture part is not touched, yet. I have not included the changes regarding to the SND_SOC_DAPM_OUTPUT() things. So you have one (actually two) outputs and you can use the mixer interface to select where the audio actually routed. The next step is to make correct dapm mapping for the TWL, but that will take some time. Please comment, if I'm doing something that I should not. --- Peter Ujfalusi (9): ASoC: TWL4030: Change the Master volume control to TLV ASoC: TWL4030: Add CGAIN volume control ASoC: TWL4030: Add helper function for mux handling.

[alsa-devel] Infrasonic Quartet
by Vedran Miletić 25 Nov '08

25 Nov '08

Auzen started to distribute one cool new Envy24HT-S card, and it looks really interesting to me. Specs are awesome, and it also has word clock on card! http://www.auzentech.com/site/products/infra_quartet.php http://www.infra-sonic.com/site/p_PCI_quartet.php http://www.newegg.com/Product/Product.aspx?Item=N82E16829156007 According to envy24.svobodno.com, it has: Infrasonic Quartet 0x3030 0x4953 Envy24HT-S - supported by ALSA AK4620B (ADC / DAC) - not sure, probably not supported? AK4112 - not sure either? However it has Xilinx on card in similar way as ESI Juli@ does, so it's probably not a standard Envy24HT-S card. Any ideas if this card could be supported? -- Vedran Miletić

[alsa-devel] [topic/asoc][RFC 0/1] ASoC: OMAP: Add support for mono link configuration to McBSP DAI
by Jarkko Nikula 25 Nov '08

25 Nov '08

Hi I'm trying to cover also pure mono codecs like bluetooth audio with McBSP DAI driver. Protocol part is trivial like patch here but interfacing with machine driver is somewhat question mark. With this patch, machine driver needs to "hack" with cpu_dai in its init function: cpu_dai->playback.channels_min = 1; cpu_dai->playback.channels_max = 1; cpu_dai->capture.channels_min = 1; cpu_dai->capture.channels_max = 1; Another idea is to introduce new omap_mcbsp_dai_mono[] array in omap-mcbsp.c and initialize those with modified builder macro, e.g: -#define OMAP_MCBSP_DAI_BUILDER(link_id) \ +#define OMAP_MCBSP_DAI_BUILDER(link_id, min_ch, max_ch) \ { \ .name = "omap-mcbsp-dai-"#link_id, \ .id = (link_id), \ .type = SND_SOC_DAI_I2S, \ .playback = { \ - .channels_min = 2, \ - .channels_max = 2, \ + .channels_min = (min_ch), \ + .channels_max = (max_ch), \ ... struct snd_soc_dai omap_mcbsp_dai[] = { - OMAP_MCBSP_DAI_BUILDER(0), - OMAP_MCBSP_DAI_BUILDER(1), + OMAP_MCBSP_DAI_BUILDER(0, 2, 2), + OMAP_MCBSP_DAI_BUILDER(1, 2, 2), #if NUM_LINKS >= 3 ... and +struct snd_soc_dai omap_mcbsp_dai_mono[] = { + OMAP_MCBSP_DAI_BUILDER(0, 1, 1), + OMAP_MCBSP_DAI_BUILDER(1, 1, 1), +#if NUM_LINKS >= 3 ... but this looks a bit overkill if typical configuration has only one such a mono link and might confuse if a machine driver still needs to reference those arrays using sequential array index like: .cpu_dai = &omap_mcbsp_dai[0], and .cpu_dai = &omap_mcbsp_dai_mono[1], sequential since if I like that cpu_dai->id is also sequential for links. Opinnions or better ideas :-) -- Jarkko

Without a model option all snd modules were loaded, but no card was detected. Using the option model=medion, resulted in the card being detected, but problems with alsamixer as below. model=mitac gives same results as below. <quote from Graeme's reply on user list> [graeme@flintstone ~]$ amixer ALSA lib simple_none.c:1491:(simple_add1) helem (MIXER,'Headphone Playback Switch',0,2,0) appears twice or more amixer: Mixer default load error: Invalid argument [graeme@flintstone ~]$ alsamixer ALSA lib simple_none.c:1491:(simple_add1) helem (MIXER,'Headphone Playback Switch',0,2,0) appears twice or more alsamixer: function snd_mixer_load failed: Invalid argument <end quote> Then I searched through the changelog, found the bug report about the codec conflicts, and suggested probe_mask=1, which has got the sound working. I think I've gone about as far as I can now, which is why I'm posting this to the devel list. Nigel.

[alsa-devel] Advice requested for developing C01U support via snd-usb-audio
by Keith A. Milner 24 Nov '08

24 Nov '08

Hi, New to this mailing list so please go easy on me. I've been reading through the Alsa docs, wiki, and still not sure of the best approach, so looking for advice from the experts. I'm looking to develop support for the Samson C01U USB studio microphone. http://www.samsontech.com/products/productpage.cfm?prodID=1810 This currently does work via the snd-usb-audio alsa driver, but not in a way that is particularly usable (to the extent that many users have been reporting it as "not working". I thought I might attempt to remedy this. The problem is that, internally, the device contains two digitally controlled amplifiers. Both of these gain controls are exposed via the USB interface (and, hence, by snd-usb-audio) and you can even access the audio stream which is output from each amp. The problem is the raw gain controls are not meant to be accessed directly in this way. The output of one of the amps is fed into the input of the other. With the Windows and Mac OSX drivers, only one gain control is presented. When this is is altered, the driver adjusts the gain of both amplifiers in order to get the correct output level but with minimum noise. In effect, there is a "virtual gain control" which is used to adjust the real gain controls in a predefined way. By careful "twiddling" of the controls it's possible to get the microphone working properly, but it is, quite frankly, a very poor way to handle the problem and is really beyond what should be expected of most users. I would like to do something about this if I can. My aim is to develop something which presents a single gain control to users which controls the internal amp gains in a sensible way. The question is, what is the best way to approach this? Looking at it, I believe there are three possible approaches. In order of my preference they are: 1) Develop at alsa driver level to get a driver which presents a single mixer control to users 2) Develop a new plugin for alsa which can be patched in via asoundrc to provide a generic "Virtual gain control" 3) Provide a user-space tool, a bit like envy24control, which provides this capability My question to the alsa-devel community is which path should I take? As I said my preference is to do something at the driver level simply because it would be most transparent to users and applications: it would simply work. It may also require less code. If this is the correct path to take, this then presents some sub-options (again in order of preference): a) Patch the existing snd-usb-audio driver with some vendor-specific code for this devices (and others which will be similar, like the C03U) b) Fork the snd-usb-driver into a new vendor-specific version and modify as before I prefer a) again because it is transparent to the users, whilst b) will require modprobe or udev configuration, but there may be reasons why it is undesirable to "bloat" the code of snd-usb-audio with vendor-specific tweaks. Bear in mind at this stage I haven't even looked at any of the code yet. Once I do I'm sure to have more questions. But at the moment my question is simply: which is the best way to approach this to be compatible with the aims and philosophy of Alsa? Many thanks, -- Keith A. Milner

[alsa-devel] [PATCH] Added Realtek ALC888 model entry for the Acer Aspire 4930G laptop
by Petry Vincent 24 Nov '08

24 Nov '08

Hello, I would like to contribute a patch that adds a model entry for the Acer Aspire 4930G laptop. Its chipset is a Realtek ALC888S-VC. The new model is based on the "acer" model and fixes the following bugs missing features: - https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4223 Reversed stereo (invalid report, please close it) - https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4224 Headphone jack sense - https://bugtrack.alsa-project.org/alsa-bug/view.php?id=4225 Internal mic - channel mode (it was missing from the base acer model) The model name is "acer-aspire-4930g" but could be renamed to something more general, if necessary. See attached patch file. It has been made against alsa-driver-1.0.18a. Thanks, Vincent Petry

[alsa-devel] Suggestion: Jack nodes detection
by Vincent Petry 24 Nov '08

24 Nov '08

Hi, I have noticed that from one model to another in ALC888 (maybe others as well), the nodes for Int speakers, HP out, are not always the same. But in the current driver model in patch_realtek.c we always hard-code the node numbers, for example 0x14 for int speakers, 0x15 for hp out, etc. It would be good to have it this way: 1. Add a spec attribute that contains the output nids in a given order or a map, like this for my laptop: alc888_acer_aspire_jack_nids = { {0x14, NID_INT_SPEAKER}, {0x15, NID_HP_OUT}, {0x18, NID_MIC_IN}, {0x1a, NID_LINE_IN}, {} }; For another laptop, that has built-in subwoofer: alc888_fujitsu_xa2530_jack_nids = { { {0x14, NID_INT_SPEAKER}, {0x15, NID_INT_SPEAKER}, // subwoofer, also considered as int speaker for the jack sense muting {0x17, NID_LINE_OUT}, // this is also side {0x18, NID_MIC_IN}, {0x1a, NID_LINE_IN}, {} }; This way we could then use a function to access the NID number of each one of them, for example get_jack_nid(..., NID_INT_SPEAKER). 2. Once this is implemented, we could add a detection routine that would build the above map automatically, based on the spec info returned by the codec. 3. Then I think we should add some special "detection" model that has no hard-coded values that anyone could use by default, if no suitable model def exists. How about this idea? Is someone already working on it? Thanks, Vincent Petry

[alsa-devel] Problem: different volumes for different jacks in ALC888
by Vincent Petry 22 Nov '08

22 Nov '08

Hi, We have designed a new model for the following laptop: Amilo Xa3530 from Fujitsu Siemens (see bug report 0004240 for alsa-info). The chipset is Realtek ALC888. When using channel mode with 6ch or 8ch, the mic-in jack (0x18) is converted to an output (PIN_OUT 0x40). The problem is that the CLFE channel (0x0e) on the mic-in jack (0x18) is not loud enough. When reassigning the CLFE (0x0e) to the line-out jack (0x17), the volume is at a normal level. But in the codec there is no volume difference between the connection paths from mic-in and side path. I saw that the Mic-in also has a VREF value, but changing it doesn't affect the volume. AFAIK the VREF value only affects Has someone met this kind of issue before? Thanks, Vincent Petry

I've taken some time to fix some autotools nitpicks and some generic optimisations, I hope they can be useful: git://git.flameeyes.eu/others/alsa/alsa-lib.git flameeyes Diego E. 'Flameeyes' Pettenò (5): Don't use AC_CANONICAL_SYSTEM, only use AC_CANONICAL_HOST. Add the attributes.m4 macro file from xine/lscube. Check for --no-undefined linker flag and use it. Make sure that python libraries are passed through LIBADD. Make some static tables and strings constants. git://git.flameeyes.eu/others/alsa/alsa-plugins.git flameeyes Diego E. 'Flameeyes' Pettenò (6): Add the attributes.m4 macro file from xine/lscube. Check for --no-undefined linker flag and use it. Cleanup flags in maemo/Makefile.am [RFC] Don't use pow() for calculating a power of 2, use shift instead. Make some static tables and strings constants.

[alsa-devel] Alsa "short read" questions
by Pierre Vanhoucke 21 Nov '08

21 Nov '08

Hi All, Is there anybody out there who can help me to answer the following questions: I have converted an application called Linrad ( http://www.nitehawk.com/sm5bsz/linuxdsp/linrad.htm ) from OSS to ALSA. Linrad is a remarkable DSP application used worldwide by many radio-hams. I am facing hereby a problem with a "short read" : An ALSA device is opened in blocking mode: ********************************************* err=snd_pcm_open(&rx_ad_handle, rx_sndin_plughw_pcm_name, SND_PCM_STREAM_CAPTURE, 0); ********************************************* When I subsequently read the device with following statement I sometimes get a "short read": ******************************************** err=snd_pcm_readi(rx_ad_handle,rxin_isho, rxad.block_frames); if((unsigned int)err != rxad.block_frames) { if(err == -EPIPE) // EPIPE, try recovery { err= snd_pcm_recover(rx_ad_handle, err, 0); if(err < 0)lirerr(1108); // recovery failed } else { if(err < 0) { lirerr(1113); // catch all } else { lirerr(1116); // short read } } } } ************************************************** Here are my questions: 1. How is it possible to get a "short read" in blocking mode ? I would think that in blocking mode the control is only returned after the read is completed. 2. What are the possible causes for a "short read" ? 3. What can be done to avoid a "short read" ? 4. How am I supposed to recover from a "short read"? Best regards, Pierre Vanhoucke/ ON5GN

Hi Shane, Apply this patch and run "echo speakers f > /proc/asound/card0/eld\#3". That will make the ELD "speakers" field right. Thanks, Fengguang --- support writing to the ELD proc file Allow users to fix quicks of ELD ROMs by writing new values to the ELD proc interface. The format is one or more lines of "name hex_value".

This typically compresses by a factor of between two and three, allowing a disc to contain 80 minutes of both 2-channel and 5.1-channel sound. > > > The speakers 0 line is a bit confusing, not sure if that's > > > > Yes it's unexpected.

Takashi, I'd suggest to support writing to the ELD proc interface to alter the internal ELD struct. This could let users debug/fix quicks conveniently.

Hi alsa devels, Thanks for your suggestions. Here is the patch for the register default values. The defaults are chosen for minimal gain settings of the input and output devices of the CODEC. If asked for i can send the details of each register. I will format and send the other patches soon.

[alsa-devel] [PATCH 1/2] ALSA: ASoC: ssm2602, wm8903: Fix priv substreams refs
by Karl Beldan 20 Nov '08

20 Nov '08

ssm2602.c and wm8903.c read: "The DAI has shared clocks so if we already have a playback or capture going then constrain this substream to match it." Let ssm2602.c handle this the same way as wm8903.c and highlight possible race pitfall in both files. This fixes subsequent failures of snd_pcm_hw_constraints_complete after closure of a stream. NOTE: - The ssm2602 allows pairs of non-matching PB/REC rates. - This is a fix for less evil: The logic is flawed (e.g. the slave might startup before the master's rate and sample_bits are set).

[alsa-devel] Creative X-Fi Xtreme Audio (CA0110 chip)
by Manuel C. 20 Nov '08

20 Nov '08

Hi, I want to bring to your attention the Creative X-Fi Xtreme Audio card with CA0110 chip, it is also bundled with some MSI motherboards. CA0110 web page: http://www.creative.com/oem/products/chips/CA0110.asp >From that web page: "CA0110 is a PCI Express audio chip using the CA0111 audio mode or High Definition Audio mode. [...] CA0106 mode - Same as original CA0111." So it should be a PCI Express version of the CA0111 chip (and CA0111 could be similar to the CA0106 chip). The CA0110 chip isn't even listed in the Creative products matrix on the wiki. Is a CA0110 driver under development? Thank you.

[alsa-devel] Alsa "short read"
by Pierre Vanhoucke 20 Nov '08

20 Nov '08

Hi all, Is there anybody out there who can help me to answer the following questions: I have converted an application called Linrad ( http://www.nitehawk.com/sm5bsz/linuxdsp/linrad.htm ) from OSS to ALSA. Linrad is a remarkable DSP application used worldwide by many radio-hams. I am facing hereby a problem with a "short read" : An ALSA device is opened in blocking mode: ********************************************* err=snd_pcm_open(&rx_ad_handle, rx_sndin_plughw_pcm_name, SND_PCM_STREAM_CAPTURE, 0); ********************************************* When I subsequently read the device with following statement I sometimes get a "short read": ******************************************** err=snd_pcm_readi(rx_ad_handle,rxin_isho, rxad.block_frames); if((unsigned int)err != rxad.block_frames) { if(err == -EPIPE) // EPIPE, try recovery { err= snd_pcm_recover(rx_ad_handle, err, 0); if(err < 0)lirerr(1108); // recovery failed } else { if(err < 0) { lirerr(1113); // catch all } else { lirerr(1116); // short read } } } } ************************************************** Here are my questions: 1. How is it possible to get a "short read" in blocking mode ? I would think that in blocking mode the control is only returned after the read is completed. 2. What are the possible causes for a "short read" ? 3. What can be done to avoid a "short read" ? 4. How am I supposed to recover from a "short read"? Best regards, Pierre Vanhoucke/ ON5GN

[alsa-devel] PCM3008 ALSA Soc driver and Lyrtech SFFSDR board audio support (v2)
by Hugo Villeneuve 19 Nov '08

19 Nov '08

Reworked and splitted patch based on Mark Brown comments. Mark, thank-you for your comments. I implemented almost all of your suggestions, except for the de-emphasis control because I don't really know how I can export (and test) that interface. Like you said, maybe we or someone else can do it later. Hugo Villeneuve

[alsa-devel] Old OMAP mailing list
by Mark Brown 19 Nov '08

19 Nov '08

Please don't CC any ASoC patches to the linux-omap-open-source list - my understanding is that it should no longer be used, having been replaced by linux-omap(a)vger.kernel.org. Any posts CCed to it result in backscatter like this: On Tue, Nov 18, 2008 at 07:57:55AM -0600, linux-omap-open-source-owner(a)linux.omap.com wrote: > You are not allowed to post to this mailing list, and your message has > been automatically rejected. If you think that your messages are > being rejected in error, contact the mailing list owner at > linux-omap-open-source-owner(a)linux.omap.com. which seems a bit hostile. It'd be nice if this bounce mentioned the new list, FWIW.

The xorg git tree only contains the audio output enabling patches, but not yet ELD transferring patches. (the ELD data flow is monitor => video driver => audio driver) I called for the Xorg ELD enabling patches from Ma Ling just after replying to your email. He should send the patches soon. > population.

The ELDV(i.e. ELD Valid) is true, but the video driver obviously has no ELD data prepared for us. Thanks, Fengguang

[alsa-devel] Listing up to 8 PCM devices
by Gregoire ETIENNE 19 Nov '08

19 Nov '08

Hi, I'm currently writting a driver with up to 8 pcm devices, so I turned on "Dynamic device file minor numbers" option. But when I try to list devices through aplay or a record (which are calling ioctl with cmd SNDRV_CTL_IOCTL_PCM_NEXT_DEVICE) I can only list devices from 0 to 7. This is due to this code : linux/sound/core/pcm.c l.64 ------------------------------ case SNDRV_CTL_IOCTL_PCM_NEXT_DEVICE: { int device; if (get_user(device, (int __user *)arg)) return -EFAULT; mutex_lock(&register_mutex); device = device < 0 ? 0 : device + 1; while (device < SNDRV_PCM_DEVICES) { if (snd_pcm_search(card, device)) break; device++; } if (device == SNDRV_PCM_DEVICES) device = -1; mutex_unlock(&register_mutex); if (put_user(device, (int __user *)arg)) return -EFAULT; return 0; } ------------------------------ because SNDRV_PCM_DEVICES is defined to 8 and do not change even if I selected "Dynamic device file minor numbers" option. Is there anything I missed ?

[alsa-devel] [PATCH 0/4] multi-channel HDMI audio support
by Wu Fengguang 19 Nov '08

19 Nov '08

Hi Takashi, This patchset attempts to support multi-channel HDMI audio. It contains two basic operations: - setup the CA(channel-allocation) byte in the audio infoframe - setup the converter channel to HDMI slot mapping Please read patch 3 for more detailed descriptions: [PATCH 1/4] hda: make standalone hdmi_fill_audio_infoframe() [PATCH 2/4] hda: make global snd_print_channel_allocation() [PATCH 3/4] hda: HDMI channel allocations for audio infoframe [PATCH 4/4] hda: HDMI channel mapping cleanups The current implementation only does minimal works that ensure multi-channel audio playing out. However the wrong speakers may be selected. We could elaborate the framework/policy if it proves to be a problem. Thank you, Fengguang --

[alsa-devel] HDA-emu v0.0.3
by Takashi Iwai 18 Nov '08

18 Nov '08

Hi, right now I updated hda-emu to version 0.0.3. hda-emu is a HD-audio emulation program that is hopefully useful for testing and debugging HD-audio drivers. This version contains a simple PCM test in addition to handling of control elements. The latest package is found at ftp://ftp.kernel.org/pub/linux/kernel/people/tiwai/misc/hda-emu-0.0.3.tar.gz The git tree is git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/hda-emu.git Any fixes, improvements and feedbacks are appreciated thanks, Takashi

[alsa-devel] [PATCH 0/4] [RFC] multi-channel HDMI audio support
by Wu Fengguang 18 Nov '08

18 Nov '08

Hi all, This patchset attempts to support multi-channel HDMI audio. It contains two basic operations: - setup the CA(channel-allcation) byte in the audio infoframe - setup the converter channel to HDMI slot mapping Please check the last two patches for the detailed descriptions: [PATCH 1/4] hda: make standalone hdmi_fill_audio_infoframe() [PATCH 2/4] hda: make global snd_print_channel_allocation() [PATCH 3/4] hda: HDMI channel allocations for audio infoframe [PATCH 4/4] hda: HDMI channel mapping cleanups The current implementation only does minimal works that can ensure the multi-channel audio playing out. However the wrong speakers may be choosed, and I really need more information/knowledge/instructions from you to get it right. Thank you, Fengguang --

[alsa-devel] Jack insertion
by naveen krishna ch 18 Nov '08

18 Nov '08

Hello Alsa Devels I am working on a OMAP3 + TWL4030 combination for audio (alsa soc) I could develop the ASOC drivers with limited kcontorls and DAPM widgets for the setup. Now my issue is is there any work regarding the Headset JACK insertion/detection. Earlier there was a proposal for a jack insertion layer. Can anyone suggest me in this regard. Thank You, (: Naveen Krishna Ch :)

Dear member of the alsa time, I am not sure if this is the email addres in which it is possible to talk about a problem with the Alsa plugins, but it is the unique address that I have found. I am writing to tell you about the compatibility of the alsa plugins. There are lots of users (like me) who have the Lexicon lambda soundcard and the lexicon alpha soundcard, but alsa plugins only support the Lexicon Omega!, and it is impossible to connect our soundcards to the computer. I think that it is a problem for the Ubuntu Studio, Musix or Studio64 users, who use this devices to record and play midi songs, and I think that linux can be better than windows making audio. I would be grateful if alsa team could help us with this problem somehow. I look forward to your response. Thank you for your attention. Your faithfully, Fernando. Sorry for my bad English, I am Spanish. _________________________________________________________________ Los más de lo más, Especial Rankings http://events.es.msn.com/dinero/listas/default.aspx

Hi folks (probably Clemens). Would it be possible to to introduce a module-option variable to snd-usb-audio, so that it is possible to switch minimum period from outside usbaudio.c /* set the period time minimum 1ms */ /* FIXME: high-speed mode allows 125us minimum period, but many parts * in the current code assume the 1ms period. */ snd_pcm_hw_constraint_minmax(runtime, SNDRV_PCM_HW_PARAM_PERIOD_TIME, 1000 * MIN_PACKS_URB, /*(nrpacks * MAX_URBS) * 1000*/ UINT_MAX); With 125us my EMU USB 0404 and also my PCM2707 devices do sound better.

Do these beep widgets have the mute amp bits? If not, we'd likely need to add mute switches as well (otherwise it gets too annoying) controlling on software. Check patch_sigmatel.c in the latest master branch or topic/fix/hda branch of sound git tree: git://git.kernel.org/pub/scm/linux/kernel/tiwai/sound-2.6.git Another concern is that I don't want to add the digital beep control unconditionally. On many devices, the beep is implemented in the old good analog way. We'd need to add the check of analog/digital beep in a new spec field and in the preset table not to duplicate beep controls on these. thanks, Takashi > --- > sound/pci/hda/hda_beep.h | 2 +- > sound/pci/hda/patch_realtek.c | 62 +++++++++++++++++++++++++++++++++++++++++ > 2 files changed, 63 insertions(+), 1 deletions(-) > > diff --git a/sound/pci/hda/hda_beep.h b/sound/pci/hda/hda_beep.h > index de4036e..b483779 100644 > --- a/sound/pci/hda/hda_beep.h > +++ b/sound/pci/hda/hda_beep.h > @@ -38,7 +38,7 @@ struct hda_beep { > int snd_hda_attach_beep_device(struct hda_codec *codec, int nid); > void snd_hda_detach_beep_device(struct hda_codec *codec); > #else > -#define snd_hda_attach_beep_device(...) > +#define snd_hda_attach_beep_device(...) 0 > #define snd_hda_detach_beep_device(...) > #endif > #endif > diff --git a/sound/pci/hda/patch_realtek.c b/sound/pci/hda/patch_realtek.c > index a378c01..d586600 100644 > --- a/sound/pci/hda/patch_realtek.c > +++ b/sound/pci/hda/patch_realtek.c > @@ -31,6 +31,7 @@ > #include "hda_codec.h" > #include "hda_local.h" > #include "hda_patch.h" > +#include "hda_beep.h" > > #define ALC880_FRONT_EVENT 0x01 > #define ALC880_DCVOL_EVENT 0x02 > @@ -2788,6 +2789,7 @@ static void alc_free(struct hda_codec *codec) > kfree(spec->kctl_alloc); > } > kfree(spec); > + snd_hda_detach_beep_device(codec); > codec->spec = NULL; /* to be sure */ > } > > @@ -3960,6 +3962,12 @@ static int patch_alc880(struct hda_codec *codec) > } > } > > + err = snd_hda_attach_beep_device(codec, 0x1); > + if (err < 0) { > + alc_free(codec); > + return err; > + } > + > if (board_config != ALC880_AUTO) > setup_preset(spec, &alc880_presets[board_config]); > > @@ -5558,6 +5566,12 @@ static int patch_alc260(struct hda_codec *codec) > } > } > > + err = snd_hda_attach_beep_device(codec, 0x1); > + if (err < 0) { > + alc_free(codec); > + return err; > + } > + > if (board_config != ALC260_AUTO) > setup_preset(spec, &alc260_presets[board_config]); > > @@ -6811,6 +6825,12 @@ static int patch_alc882(struct hda_codec *codec) > } > } > > + err = snd_hda_attach_beep_device(codec, 0x1); > + if (err < 0) { > + alc_free(codec); > + return err; > + } > + > if (board_config != ALC882_AUTO) > setup_preset(spec, &alc882_presets[board_config]); > > @@ -8916,6 +8936,12 @@ static int patch_alc883(struct hda_codec *codec) > } > } > > + err = snd_hda_attach_beep_device(codec, 0x1); > + if (err < 0) { > + alc_free(codec); > + return err; > + } > + > if (board_config != ALC883_AUTO) > setup_preset(spec, &alc883_presets[board_config]); > > @@ -10739,6 +10765,12 @@ static int patch_alc262(struct hda_codec *codec) > } > } > > + err = snd_hda_attach_beep_device(codec, 0x1); > + if (err < 0) { > + alc_free(codec); > + return err; > + } > + > if (board_config != ALC262_AUTO) > setup_preset(spec, &alc262_presets[board_config]); > > @@ -11752,6 +11784,12 @@ static int patch_alc268(struct hda_codec *codec) > } > } > > + err = snd_hda_attach_beep_device(codec, 0x1); > + if (err < 0) { > + alc_free(codec); > + return err; > + } > + > if (board_config != ALC268_AUTO) > setup_preset(spec, &alc268_presets[board_config]); > > @@ -12458,6 +12496,12 @@ static int patch_alc269(struct hda_codec *codec) > } > } > > + err = snd_hda_attach_beep_device(codec, 0x1); > + if (err < 0) { > + alc_free(codec); > + return err; > + } > + > if (board_config != ALC269_AUTO) > setup_preset(spec, &alc269_presets[board_config]); > > @@ -13624,6 +13668,12 @@ static int patch_alc861(struct hda_codec *codec) > } > } > > + err = snd_hda_attach_beep_device(codec, 0x23); > + if (err < 0) { > + alc_free(codec); > + return err; > + } > + > if (board_config != ALC861_AUTO) > setup_preset(spec, &alc861_presets[board_config]); > > @@ -14578,6 +14628,12 @@ static int patch_alc861vd(struct hda_codec *codec) > } > } > > + err = snd_hda_attach_beep_device(codec, 0x23); > + if (err < 0) { > + alc_free(codec); > + return err; > + } > + > if (board_config != ALC861VD_AUTO) > setup_preset(spec, &alc861vd_presets[board_config]); > > @@ -16412,6 +16468,12 @@ static int patch_alc662(struct hda_codec *codec) > } > } > > + err = snd_hda_attach_beep_device(codec, 0x1); > + if (err < 0) { > + alc_free(codec); > + return err; > + } > + > if (board_config != ALC662_AUTO) > setup_preset(spec, &alc662_presets[board_config]); > > -- > 1.5.6.5 > > -- > To unsubscribe from this list: send the line "unsubscribe linux-kernel" in > the body of a message to majordomo(a)vger.kernel.org > More majordomo info at http://vger.kernel.org/majordomo-info.html > Please read the FAQ at http://www.tux.org/lkml/ >

[alsa-devel] possible problem in s3c24xx-pcm.c in git-devel branch
by christian pellegrin 17 Nov '08

17 Nov '08

Hi, during the porting the uda134x driver to the git devel branch of ALSA SOC I noticed a possible problem in s3c24xx-pcm.c. s3c24xx_pcm_enqueue gained a new parameter that specifies the maximum number of periods that can be enqueued. In s3c24xx_pcm_prepare, which is called on play/capture start, this is limited to 1. Unfortunately on the 2410 the result of this change is that the DMA is stopped because the autoload of the next DMA descriptor doesn't work. I copied a log at the end of this email. Look for DMT==00 after the irq signaling the end of the first period and the subsequent fail of DMA loading since the channel is stopped. Now I fixed with: --- a/sound/soc/s3c24xx/s3c24xx-pcm.c +++ b/sound/soc/s3c24xx/s3c24xx-pcm.c @@ -253,7 +253,7 @@ static int s3c24xx_pcm_prepare(struct snd_pcm_substream *substream) prtd->dma_pos = prtd->dma_start; /* enqueue dma buffers */ - s3c24xx_pcm_enqueue(substream, 1); + s3c24xx_pcm_enqueue(substream, 2); return ret; } but this really could be "playing with DMA" since I'm not sure why there is a 1 (since min_period is 2 I would guess 2 is the right value). Anyway with this change play and capture work well. # /opt/arm/alsa/bin/aplay /mp3z/prova.wav s3c24xx-pcm: Entered s3c24xx_pcm_open s3c24xx_uda134x_startup 0 31250, 132031, 66015, 44010, 33007, 26406,

17 Nov '08

Reorder HDMI audio enabling sequence so that 1) the sink knows about the coming audio stream 2) unmute 3) start transferring audio samples The theory is that in the path A=>B=>C, we first make C ready, and then enable B, and lastly allow A to send audio samples.

> It seems that there are two problems: > - the SPDIF output PID for you board is 0x10 instead of 0x06 You are right about this, it works with the patch you provided, with one caveat: ALC1200 uses ALC883 patch, so instead of changing ALC882_DIGOUT_NID, I changed ALC883_DIGOUT_NID. How did you find out that it's 0x10 instead of 0x06? Has documentation on ALC1200 become available? > - codec#1 is not probed properly I was responsible for the confusion with the missing codec. I set probe_mask=1 parameter (as suggested in some forum as a troubleshooting option for ALC1200) without trying to understand what it does. The probing actually seems to work correctly.

[alsa-devel] ALC883 recording broken
by Dmitry Nezhevenko 16 Nov '08

16 Nov '08

Hi. I'm trying to get sound recording work on my MSI M673 laptop. Currently I'm running 2.6.27 kernel with in-kernel alsa. It looks like something going really wrong. I've connected headphones to laptop, unmuted mic and configured it's gain to maximum. After this I've tried to change "Mic boost" value. First of all, "Mic boost" under "Capture" view of alsamixer don't work at all (I can't hear any changes). "Mic boost" under "Playback" works (at least I can hear less noise with 0%, more noise with 33%, more with 67%. and, that's strange, but less with 100%. (100% looks like same as 33%). I've tried all model=xxx variants for my ALC883 codec but with no success. arecord just records silence. (Mic was unmuted and Mic boost is set to maximum). Also just after modprobing snd_hda_intel with model=acer-aspire some led in headphones jack lights.. I don't know what does this means. Ubuntu 7.10 with 2.6.22 kernel and alsa 1.0.14 works a bit different. Recording works with model=acer-aspire but playback is broken (just silence). It really looks like some codec misconfiguration (probably it tries to record from incorrect line or something like this). I've found one thread at LKML (http://lkml.org/lkml/2008/6/9/331) about this codec. And it refers to some hda-verb utility that should be able to adjust some codec settings. Is there any manual available? Or any other suggestions, what I should try to debug this? I'm attaching alsa-info.sh output -- WBR, Dmitry

Yes, there's physical HDMI port on the card, which, according to the documentation, supports both video and audio. However, there's also "SPDIF OUT Mode Setting" in the BIOS allowing to choose between "HDMI Output" or "SPDIF Output", suggesting that only one can be used at a time. The description is not terribly clear though. >> Will it help to enable SND_VERBOSE_PRINTK and SND_DEBUG? > Sure it could help, and be sure to use the latest sound-2.6 git tree :-) Ok, I've done this.

[alsa-devel] xfi fatality pro gamer
by Dmitri Seletski 15 Nov '08

15 Nov '08

Hello boys and girls. I have a card (actually 3 of them, hda-intel, that doesn't work properly, usb-audio, that doesn't work properly and xfi fatality gamer pro, which you guessed by now doesn't work properly). I may test things from any of those cards if you have any interest. I know my fatality card is rather new on the market(not exactly, but...) and not very well supported. I would like to test it if you need more testers. I have got driver released on 6th of November 2008. I tryed OSS with it, it sucked badly, but at least proved that card is in working conditions. With this driver that creative released i am getting my sound applications failed miserably. I know it's crap, so instead of complaining I decided to do something about it this time. I can provide dmesg output. Anyway, let me know if you need a guinea pig(I know how to load a distro from live cd, worst case scenario, chrootig or something). Restecpa me brothers and sistas.

[alsa-devel] [PATCH RESEND 0/3] ALSA SOC driver for s3c24xx with uda134x
by christian pellegrin 15 Nov '08

15 Nov '08

This patch adds support for the UDA134X codec and a sound card definition for one of these UDAs connected to the s3c24xx. It is *heavily* based on the one made by Zoltan Devai but: 1 since the UDA is the only use of the L3 protocol I can find I just embedded a stripped-down L3 bit-banging algorithm from the original RMK work. It is really small. 2 the driver has the possibility to specify the pins used by codec via platform data so it can work on SMDK2410, SMDK2440 or any custom design. 3 it tries to guess the right clock source and divider so it is not tied to a particular crystal used. 4 it fixes some bugs. -- Christian Pellegrin, see http://www.evolware.org/chri/ "Real Programmers don't play tennis, or any other sport which requires you to change clothes. Mountain climbing is OK, and Real Programmers wear their climbing boots to work in case a mountain should suddenly spring up in the middle of the computer room."

[alsa-devel] How does usbaudio synchronize on playback?
by John Crowley 15 Nov '08

15 Nov '08

All: How is the playback data in usbaudio.c synchronized between the application writing data to the runtime->dma_area buffer and the prepare_playback_urb function copying this into URBs? To start, a series of no-data URBs are sent out. The completion routine for each URB then calls prepare_playback_urb, which copies more data into the URB, and this URB is then passed to the USB system to be sent to the device. prepare_playback_urb copies data from the runtime->dma_area to the urb->transfer_buffer area. It maintains subs->hwptr_done to record what data has been copied, and wraps at runtime->buffer_size since this is a circular buffer. It also recognizes when runtime->period_size has been exceeded and invokes snd_pcm_period_elapsed to tell the application that more playback data is needed. What I don't understand is how does prepare_playback_urb ensure that more playback data has actually been written into the buffer? In our case, we are streaming audio over a WAN, so we increased the number of URBs to 16, with up to 32 packets per URB, to get a lot of data going on-the-fly over a high latency link. The problem is that we are getting erroneous data, and suspect that it is caused by this synchronization issue. When the initial no-data URBs are completed, the prepare_playback_urb logic copies a lot of data from the buffer into new URBs -- but apparently no playback data has been written into the buffer yet by the application. If we insert logic to arbitrarily slow down the prepare_playback_urb logic, then the data appears to be correct. But this is a (very) weak solution. We also tried to save the runtime->control->appl_ptr value in order to calculate how much new application data is available, but discovered that appl_ptr is evidently not being updated (always zero). (running 2.6.23 kernel). Are we missing a key concept? Is there a way to reliably determine how much data the application has actually written into the buffer? Thanks for your help ...

[alsa-devel] Using period events
by Bankim Bhavsar 14 Nov '08

14 Nov '08

Hi, I used async notification mechanism provided by alsa-lib. Since they use signals I ran into all sorts of issues. I should have read this post before http://mailman.alsa-project.org/pipermail/alsa-devel/2008-May/008030.html Definitely not the way to go ahead. I second the argument to remove that feature from alsa-lib altogether. We need a mechanism wherein the alsa subsystem notifies a polling thread that a "period" of sound bytes has been completed. Using snd_pcm_sw_params_set_period_event() will suffice? I took a cursory look at the alsa-lib and it seems a timer is used for this purpose. Is this well supported on majority of sound cards out there (alsa version 1.0.17+)? I want to make sure before I use this alternative approach. Thanks, Bankim.

Got, a SD card, and with help of pciehp it works almost perfectly in both slots. Almost, due to the fact that R/O switch is ignored.

[alsa-devel] problem with snd_hda_intel and ALC889a
by G.Bitzer 14 Nov '08

14 Nov '08

Hi All, I have a problem I think caused by ALSA. But first the facts. My box runs Gentoo Linux, kernel 2.6.25-gentoo-r7, amd64, on a Gigabyte board with the following sound hardware (excerpt from lspci -vv): 00:14.2 Audio device: ATI Technologies Inc SB600 Azalia Subsystem: Giga-byte Technology Device a002 Control: I/O- Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- DisINTx- Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=slow >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 32, Cache Line Size: 4 bytes Interrupt: pin ? routed to IRQ 16 Region 0: Memory at fe024000 (64-bit, non-prefetchable) [size=16K] Capabilities: [50] Power Management version 2 Flags: PMEClk- DSI- D1- D2- AuxCurrent=55mA PME(D0+,D1-,D2-,D3hot+,D3cold+) There is a AMD 790X chipset on the board, and a ALC889a codec. According to 'grep Code /proc/asound/card0/codec\#3' a 'Codec: Realtek ALC885' is detected. All software is self compiled, as usual with Gentoo. I can play .ogg or .mp3 files with audacious, no problem so far, also viewing/listening to .wmv files or YouTube works. But when pcm sounds are played from some games i constantly get dropouts and errors like snd_pcm_writei failed: Broken pipe preparing audio device for output snd_pcm_writei failed: Broken pipe preparing audio device for output ... or snd_pcm_writei failed: Resource temporarily unavailable snd_pcm_writei failed: Resource temporarily unavailable snd_pcm_writei failed: Resource temporarily unavailable snd_pcm_writei failed: Resource temporarily unavailable snd_pcm_writei short write: 987 out of 1024 snd_pcm_writei failed: Resource temporarily unavailable snd_pcm_writei failed: Resource temporarily unavailable idAudioHardwareALSA::Write: 1024 frames overflowed and dropped snd_pcm_writei short write: 1242 out of 2048 snd_pcm_writei failed: Resource temporarily unavailable idAudioHardwareALSA::Write: 1024 frames overflowed and dropped snd_pcm_writei failed: Resource temporarily unavailable snd_pcm_writei failed: Resource temporarily unavailable After disabling 'Aggressive power-saving on HD-audio SND_HDA_POWER_SAVE' and 'AC97 Power-Saving Mode SND_AC97_POWER_SAVE' I got less dropouts, but they were still noticable. Last but not least, my alsa is media-libs/alsa-lib-1.0.16 media-sound/alsa-headers-1.0.16 media-sound/alsa-utils-1.0.16 This are the newest ones marked as stable in portage. What can I do ? Are there any parameters for the kernel modules, to get good pcm sound ? Thanks in advance PS: I can send a report of alsa-info.sh, if this is helps

[alsa-devel] [PATCH RESEND 0/2] ALSA SOC driver for uda134x codec
by Christian Pellegrin 14 Nov '08

14 Nov '08

This patch adds support for the UDA1341 codec. It is *heavily* based on the one made by Zoltan Devai but: since the UDA is the only use of the L3 protocol I can find I just embedded a stripped-down L3 bit-banging algorithm from the original RMK work. It is really small.

[alsa-devel] [PATCH] ASoC: Fix for master playback/capture volume range for TWL4030 codec
by Peter Ujfalusi 14 Nov '08

14 Nov '08

FGAIN for playback is in range of 0-0x3f, while for capture GAIN it is in the range of 0-0x1f. The original value of 128 (0x7f) would modify the CGAIN also for playback.

[alsa-devel] Regression on alsa-driver-1.0.18a on HDA for Dell Inspiron 1521
by Manuel Naranjo 14 Nov '08

14 Nov '08

Hello guys, I just upgraded my alsa from 1.0.16 to 1.0.18a (actually I tried 1.0.18 for some days, and got lots of kernel crashes, which apparently 1.0.18a fixes). Thing is that when I try to use my headphones with 1.0.18a they don't work. I'm attaching alsa-info.sh outputs for both 1.0.16 and 1.0.18a too see if this helps. Headphones detection works pretty well, when ever I plug the jack internal speakers stop working but nothing is coming from the jack. I can hear an static sounds, so it seems like the headphones are getting the bias current, but not the signal itself. Please let me know how can I help you to debug this problem. Regards, Manuel

[alsa-devel] snd_pcm_ops
by John Kacur 14 Nov '08

14 Nov '08

As a newcomer to alsa, I have a few more probably simple questions. I noticed in the SOC drivers, that when the struct snd_pcm_ops is filled in, .copy is omitted, for example in file s3c24xx-pcm.c, you see the following initialization. static struct snd_pcm_ops s3c24xx_pcm_ops = { .open = s3c24xx_pcm_open, .close = s3c24xx_pcm_close, .ioctl = snd_pcm_lib_ioctl, .hw_params = s3c24xx_pcm_hw_params, .hw_free = s3c24xx_pcm_hw_free, .prepare = s3c24xx_pcm_prepare, .trigger = s3c24xx_pcm_trigger, .pointer = s3c24xx_pcm_pointer, .mmap = s3c24xx_pcm_mmap, }; How is this supposed to work if somewhere down the line substream->ops->copy is called? Thanks in advance for any pointers.

This suggests to me that the comment in the driver > source about synchronising playback to capture has some relevance ... Indeed. The driver would have to send the data at the exact speed of the device's internal clock, and the only way to determine that clock's speed is to capture data. So far I haven't found the time to rewrite the driver to support this synchronization mechanism. Best regards, Clemens

[alsa-devel] [RFC][PATCH] ELD routines and proc interface
by Wu Fengguang 14 Nov '08

14 Nov '08

Create hda_eld.c for ELD routines and proc interface. ELD handling routines can be shared by all HDMI codecs, and they are large enough to make a standalone source file. Some notes on the code: - Shall we show an empty file if the ELD content is not valid? Well it's not that simple. There could be partially populated ELD, and there may be malformed ELD provided by buggy drivers/monitors. So I tend to expose ELD as it is. - hdmi_show_eld() and hdmi_print_eld_info() are somehow duplicated The plan is to shrink hdmi_show_eld()/hdmi_show_short_audio_desc(), and to show a compact message at monitor hotplug and driver initialization time. - The ELD retrieval routines rely on the Intel HDA interface, others are/could be universal and independent ones. - The ELD proc interface code could be moved to hda_proc.c if necessary. - How do we name the proc file? If there are going to be two HDMI pins per codec, then the current naming scheme (eld#<codec no>) will fail. - The ELD proc file content is designed to be easy for scripts and human reading. Its lines all have the pattern: <item_name>\t[\t]*<item_value> where <item_name> is a keyword in c language, while <item_value> could be any contents, including white spaces. <item_value> could also be a null value.

[alsa-devel] [PATCH] ASoC: Fix for master playback/capture volume range for TWL4030 codec
by Peter Ujfalusi 14 Nov '08

FGAIN for playback/capture is in range of 0-0x3f. The original value of 128 (0x7f) would also modify the CGAIN, which gives undesired results. Separate control for CGAIN?

It's not in alsa-plugins/pulse, because if you send it 24-bit anything, it won't recognize that format and error out with a different message (rather than just throwing error back at aplay). Things fall down before pcm_pulse.c ever evaluates the sample format. 2. It's not in alsa-lib/pcm/pcm_plug.c, because plug intelligently works with other (non-pulse) devices: Works: aplay --device=plug:hw:0 LPCM_48khz_ST_24bit.wav and aplay --device=plug:dmix:0 LPCM_48khz_ST_24bit.wav In theory, these statements should be both true: My hw doesn't support S24_3LE, but plug converts it for me. My pulse doesn't support S24_3LE, but plug converts it for me. But there is one more layer between plug and the actual pulse plugin code: ioplug! It's non-trivial to figure out the guts of functions such as snd_pcm_ioplug_hw_refine when you have refine math going on. The refine code goes through a lot of contortions trying to get ioplug to accept a conversion, but no joy.... it appears pcm_extplug.c, the "External Filter Plugin SDK" is unhappy. So basically, the problem occurs before alsa-plugins/pulse even gets a chance to detect and deal with the problem. pcm_ioplug.c does something similar to what pcm_plug.c does with refines, just more cryptically. Since it was developed so long ago, it may not have been tested with S24_3LE, or with S24 at all. One possible ugliness is that there is no cmpxchg instruction for 24-bit values, so you'd have to do something else for synchronization. Maybe that's why it's not supported? It sounds like pulse (or any ioplug-user, in general) is not going to support S24_3LE until someone really digs in and finds out why this is erroring out. Keep in mind that there are two code paths that both hit the same problem, namely plug:pulse and pulse alone. The error returned is different, and it seems simpler to figure out why you get an error with plain pulse, rather than complicating things with plug.

Creative released a driver today.... I am hasitating to install it.. the last one was so crappy and I just installed my gentoo new ;-) But it looks really like the SOURCE, so maybe it will help to pimp the ALSA driver (would rather see an implementation in alsa then an driver from Creative) http://forums.creative.com/creativelabs/board/message?board.id=soundblaster… http://support.creative.com/downloads/download.aspx?nDownloadId=10792 Kind regards Bjoern

[alsa-devel] Asus P5QL-EM motherboard (ALC1200 codec) - no sound through S/PDIF
by Andrei Tanas 13 Nov '08

13 Nov '08

Hello, I can't get the S/PDIF out to work on P5QL-EM motherboard. First of all, it doesn't detect the board configuration correctly, the motherboard has an HDMI output and an S/PDIF header (I have a TV connected to one and an amplifier to the other, in case one output will "go live"). aplay -L normally only shows th HDMI port, however if I add this options snd-hda-intel model=6stack-dig probe_mask=1 to /etc/modprobe.d/alsa-base, it will show both. Problem is, there seems to be no signal coming out of any of the two digital ports (they are not muted in mixer) in either PCM or AC3 pass-through mode. I compiled the "alsa-kernel" hoping that the latest commits related to ALC1200 would help, but it hasn't helped. Here's the output of alsa-info.sh: http://www.alsa-project.org/db/?f=b62b56c5ce0aa383fef1be0f55b87b4e27e8ab63 Again, it's running "alsa-kernel", checked in just 12 hours ago. Let me know what I can do to help, I am a developer but Alsa is not my territory. Thanks

[alsa-devel] Git branches with Gentoo fixes
by flameeyes＠gmail.com 13 Nov '08

13 Nov '08

Hi all, Since I have just had to fix (again) an --as-needed issues on alsa-tools on the Gentoo ebuild, I've decided to clone the git repo and see to try pushing (again, I'm sure I tried before) the Gentoo-specific patches. You can find two git branches for alsa-tools and alsa-utils at these addresses: git://git.flameeyes.eu/others/alsa/alsa-tools.git git://git.flameeyes.eu/others/alsa/alsa-utils.git For the patches coming from users, the proper Author setting was done so that they are reported coming from the correct contributor.

[alsa-devel] [topic/asoc][PATCH] ASoC: OMAP: Add more supported sample rates into McBSP DAI driver
by Jarkko Nikula 13 Nov '08

13 Nov '08

Originally it was put too tight limits to support only 44.1 kHz and 48 kHz sample rates in McBSP DAI driver. Extend it now to 8 kHz - 96 kHz. With 96 kHz and 2*16 bits, bit clock is 3.072 MHz < 3.125 MHz (I2S max?). Tested on Nokia N810 with TVL320AIC33 from rates 8 - 96 kHz and on Texas Instruments Beagle with TWL4030 from rates 8 - 48 kHz.

[alsa-devel] 2.6.28-rc2-mm1 - sound semi-busted on Dell Latitude D820

Sometime between -mmotm1017 and -rc2-mm1, something odd happened to the sound subsystem. On my Dell Latitude D820, audio works OK if it's sitting there standalone, or in its docking station. However, when I plug in headphones, it goes silent. Sorry for not having any more detail, but I've not had a chance to bisect this down to a specific commit. I did run alsa-info for the two kernels, here's a diff between them. I also attached a copy of the full output for working -mmotm1017.

Hello, We can now enjoy music on HDMI monitors that are attached to Intel G35/G45 chipsets with the following X.org intel driver patches [PATCH 1/3] introduce i830_hdmi_priv.has_hdmi_sink [PATCH 2/3] enable Intel G45 integrated HDMI audio output [PATCH 3/3] enable Intel G35 SDVO HDMI audio output _and_ the corresponding ALSA patch posted at http://mailman.alsa-project.org/pipermail/alsa-devel/2008-November/012158.h… The patches are tested OK on Intel DG45ID board, HP 2230s notebook and ASUS P5E-VM board. Since the HDMI audio requires both audio and video driver support to function well, I'd like to provide an overview here. 1) driver components: A) ALSA: audio driver (the above link) B) Xorg: audio output enabling (this patchset) C) Xorg: EDID/ELD information (patches to be submitted by Ma Ling) 2) summary of the feature sets: - basic 2-channel audio: (A) is required, (B) is mostly required, (C) is not needed - 2+ multichannel audio: not tested yet; in theory we need (C) to get HDMI monitor's speaker allocation configuration; there are also bandwidth constraints that should be coordinated between audio/video drivers in the future. - non-LPCM audio: not tested yet; need more work in ALSA code. 3) summary of the work flow: - basic audio output: (A) and (B) - ALSA HDMI driver: enable pin out and unmute - ALSA HDMI driver: fill audio infoframe and enable its transmission - Xorg intel driver: enable audio output - ELD info for advanced audio capabilities: (A) and (C) - Xorg xserver: get/parse/store EDID extensions - Xorg xserver: transform EDID into ELD - Xorg intel driver: feed ELD to hardware - Xorg intel driver: set ELD-Valid flag to inform audio driver of new ELD - ALSA HDMI driver: response to unsolicited response triggered by ELDV - ALSA HDMI driver: get ELD from hardware - ALSA HDMI driver: parse and show ELD info - ALSA HDMI driver: update hardware capabilities/constraints according to ELD (TBD) That describes my understandings of HDMI audio, comments and discussions are warmly welcome.

[alsa-devel] maximum tolerable sampling frequency difference for a driver
by chri 12 Nov '08

12 Nov '08

Let's say that the driver cannot set the exact sampling frequency asked via hwparms but something near (because of the granularity of the result of the clock division). What is the maximum difference that should be accepted (in Hz or in %)? I guess that there are 2 factors playing a role: 1) if the frequency is too different then the upper layers report a undeflow/overflow 2) the sound just doesn't sound good (just a bit too presto or too adagio) So what difference should be accepted instead of returning -EINVAL? Thanks, -- Christian Pellegrin, see http://www.evolware.org/chri/ "Real Programmers don't play tennis, or any other sport which requires you to change clothes. Mountain climbing is OK, and Real Programmers wear their climbing boots to work in case a mountain should suddenly spring up in the middle of the computer room."

[alsa-devel] to get the detail information of a codec
by Wayne 12 Nov '08

12 Nov '08

Hi all, Now I'm writing a program which can list some capabilities of my codec, such as what rates and formats my codec supports. By typing 'cat /proc/asound/card0/codec#0', you can see the detail of your card. I want to write a program which can show these information by alsa-lib. However, I couldn't find a function in alsa-lib which can tell me the formats and rates. Is there a way to get this detail? By the way, my card is intel-hda and the codec is alc268. Another question is I've seen the word "element" in many function, such as snd_ctl_event_elem_get_device. What "element" means in alsa world? I couldn't find any artile mentioning it!!! Thanks all!!!
