[alsa-devel] [PATCH 1/1] USB audio quirk for Roland VG-99 advanced mode
by pete.leigh＠gmail.com 21 Oct '12

21 Oct '12

From: Pete Leigh <pete.leigh(a)gmail.com> Without this quirk the VG-99 will work in standard mode (set under USB on System menu page 2) giving 16 bits at 44.1 Khz audio in/out but no midi, and is not recognised when set to advanced mode. After applying this, I can also use the VG-99 in advanced mode: 24 24 bits audio in/out at 44.1 Khz, and midi in/out. Sysex is so far untested. In standard mode, the device appears with ID 0x00b3, so the behaviour isn't affected by this quirk. Thanks to Clemens Ladisch for simplifying and correcting my initial attempt!

[alsa-devel] calling snd_ctl_notify from mixer ctl_put
by Ondrej Zary 21 Oct '12

21 Oct '12

Hello, I want to enable/disable some mixer controls based on state of another control (switching between limiter and AGC mode). So I (re)set the SNDRV_CTL_ELEM_ACCESS_INACTIVE flag in kctl->vd[0].access and then call snd_ctl_notify(card, SNDRV_CTL_EVENT_MASK_INFO, &kctl->id); Everyting from ctl_put() mixer callback. When changing the control value in alsamixer, it crashes with: alsamixer: simple.c:948: snd_mixer_selem_get_enum_item: Assertion `(elem)->type == SND_MIXER_ELEM_SIMPLE' failed. When the snd_ctl_notify() call is commented-out, it does not crash. There is snd_ctl_activate_id() function in sound/core/control.c (not used by any driver, btw.) which does the same, protected by card->controls_rwsem. However, it locks up on that semaphore when called from the mixer callback. Oxygen/Xonar WM8776 driver is doing the same thing - I wonder if I'm doing something wrong or if that driver crashes alsamixer too? Is there any way to do this properly? -- Ondrej Zary

[alsa-devel] [PATCH 0/9] Fixes for RME MADI cards
by Adrian Knoth 20 Oct '12

20 Oct '12

Hi! I've spent another afternoon at IOSONO to fix a series of bugs in the hdspm driver. Andre Schramm and me have tested almost all patches on a box with two PCIe MADI cards and one PCI MADI card. The DDS/Varispeed patch has only been tested on my RayDAT, the sync_in detection for AES32 has not been tested at all, though the documentation is pretty clear that the previous bit position was wrong. If there are AES(32) owners with two or more cards out there, please test and report back. The typo and the coding style patches have not been tested, since they're trivial. Cheers Adrian Knoth (9): ALSA: hdspm - Allow DDS/Varispeed to be set from userspace ALSA: hdspm - Report external rate in slave mode on PCI MADI ALSA: hdspm - Fix sync check reporting on all RME HDSPM cards ALSA: hdspm - Fix reported autosync_sample_rate ALSA: hdspm - Also report autosync_sample_rate on MADI and MADIface ALSA: hdspm - Fix sync_in reporting on RME MADI cards ALSA: hdspm - Fix sync_in detection on AES/AES32 ALSA: hdspm - Fix typo in kcontrol element on RME MADI cards ALSA: hdspm - Fix coding style in CTL_ELEM macros sound/pci/rme9652/hdspm.c | 232 ++++++++++++++++++++++++++------------------- 1 file changed, 137 insertions(+), 95 deletions(-) -- 1.7.10.4

[alsa-devel] Fwd: Support for Roland VG-99 (working code, but could use help)
by Pete Leigh 20 Oct '12

20 Oct '12

Hi, I tried posting this a couple of days ago, but no response... I'm wondering if the (text) attachment stopped people from seeing it, or if there's something else I missed? It's just a request to look over the lsusb output and new quirks-table entry included, with a view to getting this added to a release. Since the initial post, I've done more testing (I'm using a kernel based on 3.4.11-1.rt19.1.fc17.ccrma.x86_64.rt) and everything seems to work fine (including midi in, which I wasn't sure of at the time of posting) apart from one apparently cosmetic issue - the device name no longer shows up in lsusb output, though it did before applying the quirk. (?) I'll include the quirk entry as text rather than an attachment this time. If I actually need to go through the process of generating a patch and sending mail via git, as per the developer page on the alsa-project site, could someone let me know, and I'll give it a go (it's something I was hoping to avoid, I admit!) Thanks, - Pete. ---------- Forwarded message ---------- The VG-99 is a guitar processor with a usb interface which offers 2x16bit 44100 pcm in and out streams in its basic usb mode, and 2x24bit 44100 in/out + midi in the advanced mode connection mode. Basic mode works fine with usb snd driver, but the device isn't recognised when set to advanced mode (this is done under USB on page 2 of the "system" config menu) I've used the lsusb -v output (below) to guess at an addition to sound/usb/quirks-table.h to try and get this working. On initial (brief) testing, audio in/out at 24bits (as shown by jackd output) and midi (out, at least) are all working. I'll attach the quirk, and would be pleased if someone could look at it, and the lsusb output, and fix up any deficiencies (it's purely voodoo here :-D) and maybe get it or something like it into the official source... please let me know if changes need to be tested.

[root@localhost ~]# lspci |grep Mult 01:00.0 Multimedia audio controller: Xilinx Corporation RME Hammerfall DSP MADI (rev d2) 02:00.0 Multimedia audio controller: Xilinx Corporation RME Hammerfall DSP MADI (rev d2) The SyncOut of card 2:00 was plugged to the SyncIn of 1:00 and 1:00 was put to AutoSync-mode automatically upon boot. Problem is that the amixer output seems to be inconsistent and differs from the proc output as well, so I'm not sure which one to trust.

A cover letter can be a good way to *summarize* a long patch series so readers are less daunted, but any information that was needed to know in order to evaluate a patch, briefly stated, should be in the commit message that actually gets committed.

[alsa-devel] Non-interleaved with plughw
by Prasant J 19 Oct '12

19 Oct '12

Hi, My hardware supports only interleaved access and I'm recording and playing using hw:0,0. Currently I provide interleaved buffers to the device. What I read is that plughw device can convert non-interleaved buffers to interleave buffers before sending to hardware. I want to reduce complexity of my application and want to use plughw. But I'm not able to get good documentation or examples of the same. Can anyone point out to me? Regards, -Prasant

You must be doing something wrong. I'm doing 32-bit, 16-channel input at 51.2kHz on a OMAP-L138 (an ARM9 CPU at 450 MHz) under Linux and it's using no more than 25% CPU for that.

[alsa-devel] Kernel panic with SB Live (snd_emu10k1) when sharing interrupts
by John Paul Adrian Glaubitz 19 Oct '12

19 Oct '12

Hello, I have a Creative SoundBlaster Live! PCI (PCI-IDs: 1102:0002 and 1102:7002) which I recently ran into trouble with. I used the SB Live! to replace my SB128 PCI which ran fine in the configuration (ASUS P8B-C/4L, see attached output from dmesg and lspci). Once I swapped the sound cards, I booted up the machine and immediately ran into a kernel panic [1] which seems to indicate that there is a problem with interrupt sharing. I there removed the Firewire card which was placed adjacent to the SB Live and the machine ran stable again. I assume that the snd_emu10k1 driver is sometimes not handling shared interrupts properly, isn't it? I wanted to report this as a bug in the ALSA bug tracker [2], but alas the tracker is currently down. I'm attaching the output of dmesg [3] as well as lspci [4]. Will provide more information if requested. Cheers, Adrian > [1] http://users.physik.fu-berlin.de/~glaubitz/emu10k1_panic.jpg > [2] https://bugtrack.alsa-project.org/alsa-bug/ > [3] http://users.physik.fu-berlin.de/~glaubitz/dmesg_emu10k1.txt > [4] http://users.physik.fu-berlin.de/~glaubitz/lspci_emu10k1.txt

[alsa-devel] ESI drivers
by Neil Mcbennett 18 Oct '12

18 Oct '12

Hi, I am not a developer and probably shouldn't even be here, but I do have a question that is probably best answered from this forum. I've been looking at the ESI website and I notice that there is some ALSA support for a few of their cards... http://www.alsa-project.org/main/index.php/Matrix:Vendor-ESI The interface I'm most interested in isn't on this list (MaXiO 032e) I decided to call the technical support number in the UK and ask them what their position is regarding Linux. The guy I spoke to said that ESI are not going to provide an ALSA driver for these devices but they would be more than happy if someone from the ALSA community were to approach them. They would then assist in providing the necessary information. So, just wondering if anyone has already started on this or if there might be some interest in doing so? I was attracted to ESI by the fact that they have a number of PCIe interfaces which are still quite something of a rarity. Regards Neil

[alsa-devel] [PATCH v2 0/2] Convert davinci ASoC to genalloc SRAM
by Matt Porter 18 Oct '12

18 Oct '12

Changes since v1: - Rebased against uio_pruss/genalloc series v4 patches, requiring another header to be included. This series converts davinci ASoC to use genalloc and enables that support on DA850. It applies to mainline on top of the uio_pruss/genalloc series [1] which allows DaVinci to provide a gen_pool via pdata for driver use. I've tested this on the AM180x EVM. Note that prior to this, the SRAM paths in the driver were completely unused. I've only enabled ping-pong buffering on the platform I can test as it's best to allow those with DM644x and similar platforms to set the playback/capture sram size to something that's known to work for them.

How about employing autosuspend with a few ms > delay? Yes, employing the autosuspend is workable method too.o But it's a little more complicated then this patch. You have to create a thread or workqueue to do the job. What's more, I think other DMA engine may also meets the same issue as the mxs-dma, such as the imx-sdma. It's somehow a common issue to disable the clocks when no one use the DMA engine. Do you also suggest employing the autosuspend? Why not use a simple way to handle this issue? When the dma device want to use a DMA engine, it just needs to issue a DMA_START command. thanks Huang Shijie Huang Shijie

[alsa-devel] [PATCH] dma: add new DMA control commands
by Huang Shijie 18 Oct '12

18 Oct '12

From: Huang Shijie <shijie8(a)gmail.com> [1] Why add these new DMA control commands? In mx6q, the gpmi-nand driver is the only user of the APBH-DMA. The dma clock is enabled when we have successfully requested a DMA channel. So even when the gpmi-nand driver does not work, the dma clock(apbh-dma) still runs in high speed (198MHz). To save some power, it is better to disable the dma clock when the dma device, such as gpmi-nand, is not working anymore. When the dma device becomes work again, enable the dma clock again. [2] add new DMA control commands: DMA_START/DMA_END DMA_START: do some preprations to start the DMA engine, such as enable the necessary clocks. DMA_END: do some works to end the DMA engine, such as disable the necessary clocks. [3] This patch does not change any logic in i2c-mxs driver and mxs-pcm driver. But for gpmi-nand driver, we will enable the the clock only when we select the nand chip, and want to do some real jobs with the nand chip. For mxs-mmc driver, disable the dma clock in the suspend; and enable the dma clock in the resume.

[alsa-devel] Non-Interleaved access method?
by Prasant J 18 Oct '12

18 Oct '12

Hi, When the application set the access method to non-interleaved, that means that the ALSA application will deliver the non-interleaved buffers to alsa subsystem & the alsa subsystem will interleave the data before sending out the data to the hardware. Am I correct? Or non-interleaved means that the data will be sent out in non-interleaved manner itself? Regards, -Prasant

[alsa-devel] ASoC: mmap or read/write?
by Prasant J 18 Oct '12

18 Oct '12

Hi, I'm writing an alsa application for recording & playing 16 channel audio. The application is intended to run on an embedded platform & the resources are highly constrained. My application is not performing well with read/write methods. I'm considering using mmap but not able to get the right documentation or start, so I want to know whether mmap really offers any advantages or not. Does the mmap method has any advantages over read/write? Is there any thumb rule to decide when to use mmap or read/write? -Prasant

[alsa-devel] [PATCH 1/2] ARM: OMAP: Trivial driver changes to remove include plat/cpu.h
by Tony Lindgren 17 Oct '12

17 Oct '12

Drivers should not use cpu_is_omap or cpu_class_is_omap macros, they should be private to the platform init code. And we'll be removing plat/cpu.h and only have a private soc.h for the arch/arm/*omap* code. This patch is intended as preparation for the core omap changes and removes the need to include plat/cpu.h from several drivers. This is needed for the ARM common zImage support. These changes are OK to do because: - omap-rng.c and hsmmc.c don't need plat/cpu.h - omap-aes.c and omap-sham.c get the proper platform_data passed to them so they don't need extra checks in the driver - omap-dma.c and omap-pcm.c can test the arch locally as omap1 and omap2 cannot be compiled together because of conflicting compiler flags Cc: Deepak Saxena <dsaxena(a)plexity.net> Cc: Matt Mackall <mpm(a)selenic.com> Cc: Herbert Xu <herbert(a)gondor.apana.org.au> Cc: David S.

[alsa-devel] [PATCH] ASoC: codecs: da9055: DAPMise Headphone and Lineout enable controls
by Ashish Chavan 17 Oct '12

17 Oct '12

This patch DAPMises headphone and lineout output enable controls. Earlier these output enable bits were permanently turned on in probe. In da9055 codec, right outmixer is directly connected with right HP and Line out. This resulted in two side effects, (1) When you only want to use lineout, right HP (and connected charge pump) also gets enabled (2) When you only want to use stereo HP, lineout also gets enabled This patch adds three switches to select which output(s) should be enabled.

[alsa-devel] [PATCH] ALSA: hda - Always check array bounds in alc_get_line_out_pfx
by David Henningsson 17 Oct '12

17 Oct '12

Even when CONFIG_SND_DEBUG is not enabled, we don't want to return an arbitrary memory location when the channel count is larger than we expected. Cc: stable(a)kernel.org Signed-off-by: David Henningsson <david.henningsson(a)canonical.com> --- Notes: This was found while debugging an OOPS on kernel 3.2. See https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1067269 for details. The badness calculation was improved in kernel 3.4; so not sure if the same could happen in later kernels, but at least apply to kernels <= 3.3 would make sense. Also adding to current trees (3.7, 3.8) would make sense IMO, just as extra safety. sound/pci/hda/patch_realtek.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/sound/pci/hda/patch_realtek.c b/sound/pci/hda/patch_realtek.c index 2d2bb66..651822c 100644 --- a/sound/pci/hda/patch_realtek.c +++ b/sound/pci/hda/patch_realtek.c @@ -2599,8 +2599,10 @@ static const char *alc_get_line_out_pfx(struct alc_spec *spec, int ch, return "PCM"; break; } - if (snd_BUG_ON(ch >= ARRAY_SIZE(channel_name))) + if (ch >= ARRAY_SIZE(channel_name)) { + snd_BUG(); return "PCM"; + } return channel_name[ch]; } -- 1.7.9.5

[alsa-devel] [PATCH] hda-analyzer: Ignore unknown lines in proc file
by David Henningsson 17 Oct '12

17 Oct '12

With newer kernels, the proc file sometimes add more information. This makes hda-analyzer ignore such new additions by default, instead of the current behaviour (which is to crash with a stack trace). This way you can run an older hda-analyzer with a newer kernel. A recent example is the addition of "IEC Coding type" to all HDMI codecs.

Re: [alsa-devel] Silence playback during XRUN
by Babu, Ramesh 16 Oct '12

16 Oct '12

Hi I am trying to configure my application to use silence playback of ALSA in case XRUN. I am configuring the silence parameters as below: silence_threshold = 0 silence_size = boundary stop_threshold = bounday Using the above configuration I can see that ALSA sends silence during XRUN. But I am experiencing audio is jerky, when application starts sending the data after the XRUN. I noticed someone has met similar situation. http://mailman.alsa-project.org/pipermail/alsa-devel/2011-December/046894.h… Do I need to modify my silence settings? Anything that I need take care apart from the above mentioned parameters? Thanks Ramesh

From: Stephen Warren <swarren(a)nvidia.com> Remove includes of <mach/dma.h> from sound/soc; nothing from it is used. Remove include of <mach/dma.h> from mach-tegra/apbio.c; since the DMA transfers made by this file don't need flow-control with any peripheral, there's no need to set any slave ID. Once those changes are made, there are no remaining users of <mach/dma.h> so remove it. Drivers should get this information from device tree. This removal is necessary for single zImage.

[alsa-devel] A question about speaker volume control of Creative Recon3D
by Ming Chen 15 Oct '12

15 Oct '12

Hello All, Recently I looked into the hda code for Creative sound cards, based on linux-3.6-rc3. I found that for Ca0110 (X-Fi), the patch (Patch_ca0110.c) would call add_out_volume() (and add_mono_volume()) for those DACs (refer to the ca0110_build_controls() function). While for ca0132 (Recon3D), its patch (Patch_ca0132.c) does not call add_out_volume() for any DAC (refer to the ca0132_build_controls() function). If I play a wav file under Ubuntu, it can adjust the speaker volume successfully with the Recon3D card. Can somebody kindly tell me how the speaker volume been controlled for this card? Thanks, Ming

[alsa-devel] snd_ctl_elem_list
by Paul 15 Oct '12

15 Oct '12

Newbie. Trying to discover information about the audio hardware. Specifically about a USB microphone ( Audio-Technia AT2020USB ) and whether it has a volume control. Writing in Ada just to be difficult. Not having any problems with that though. After doing a malloc and a snd_ctl_elem_list I can use ctl_elem_list_count to get the number of elements. This number is non-zero ( 2 for the AT2020, 34 for the on-board Intel audio chip ). Then I can use ctl_elem_to get the number of used. That number is zero and prevents me from trying to access the element list. How can I find out information about the elements in the list? How do these elements become used? Is this even the correct path to try to discover the volume control? Thanks, Paul I

[alsa-devel] Support for Roland VG-99
by Pete Leigh 14 Oct '12

14 Oct '12

Hi, The VG-99 is a guitar processor with a usb interface which offers 2x16bit 44100 pcm in and out streams in its basic usb mode, and 2x24bit 44100 in/out + midi in the advanced mode connection mode. Basic mode works fine with usb snd driver, but the device isn't recognised when set to advanced mode (this is done under USB on page 2 of the "system" config menu) I've used the lsusb -v output (below) to guess at an addition to sound/usb/quirks-table.h to try and get this working. On initial (brief) testing, audio in/out at 24bits (as shown by jackd output) and midi (out, at least) are all working. I'll attach the quirk, and would be pleased if someone could look at it, and the lsusb output, and fix up any deficiencies (it's purely voodoo here :-D) and maybe get it or something like it into the official source... please let me know if changes need to be tested. Cheers, - Pete. Here's the lsusb output: Bus 001 Device 007: ID 0582:00b2 Roland Corp.

Hi all, the new USB DAC from Teac seems detected as 'Human Interface Device' instead of 'Audio'. Despite the fact it is based on a standard USB Audio class v2 controller (Tenor 8802).

[alsa-devel] bit depth issue for Scarlett 2i4
by Dan MacDonald 13 Oct '12

13 Oct '12

Hi ALSA devs! I recently bought a Focusrite Scarlett 2i4 which is advertised as being capable of recording at a max of 24bit/96Khz but when I run alsacap it reports it as 32bit: ./alsacap -R -d hw:1 *** Exploring configuration space of device `hw:1' for recording *** 2 channels Sampling rate 44100..96000 Hz Sample formats: S32_LE Significant bits: 32 It does seem to record OK but that output seems wrong and I'm slightly concerned about the waste of disk space when multitracking if I end up with 32bit files but only 24 of those bits per sample are actually being used. Thanks for your help! Dan

[alsa-devel] Question about rawmidi USB Tx buffer size
by Paul D. DeRocco 13 Oct '12

13 Oct '12

Simple question: how big is it? ALSA provides snd_rawmidi_status for reading the status structure from a rawmidi handle, and snd_rawmidi_status_get_avail to extract the number of bytes in the ring buffer from that structure, but what I want to know is how many bytes of space are available in the ring buffer, so that I know how many bytes I can write without blocking. Is the buffer size a fixed number for any particular driver? The only driver I'm concerned with is the USB MIDI driver, so that shouldn't be hardware dependent. -- Ciao, Paul D.

Hello, The reason for the breakage is the patch 1 got lost somewhere in the process. I also greped the whole tree for device_prep_dma_cyclic() and the second patch is the result of that. PS: I did build tested the series on ARM (OMAP), x86_32, x86_64 but not for ppc for sure.

Hi, these two patches are for fixing races at disconnection of USB audio devices. The first patch tries to close the race at open/close, and the next is for other PCM and mixer ops in usb-audio driver. It seems working as far as I've tested with Matthieu's test cases. thanks, Takashi

[alsa-devel] [RFC PATCH] ALSA: hda - Implement a poll loop for jacks as a module parameter

[alsa-devel] Arecord issue
by kartik natarajan 11 Oct '12

11 Oct '12

Hi, I am working on a 2.6.37 kernel and on a DM365 davinci board with a tlv320aic3254 audio codec (i2c control lines, i2s data transfer) I wanted to get the audio up on my board so got the alsa-lib and alsa-utils 1.0.25 compiled them and got the aplay to work fine. When I got to working on the arecord things haven't worked fine. I have traced all the calls and have reached so far; codec gets set properly davinci_pcm_trigger executes with success snd_pcm_sw_params() executes successfully. aplay calls begin_wave() aplay calls pcm_read() that invokes snd_pcm_readi() Finally my app seems to not go beyond the snd_pcm_start() Any assistance shall be highly appreciated! Thanks in advance, N.Kartik

[alsa-devel] Bug 48381 - [Regression][Bisected]Sound gets permanently muted a few minutes after booting
by Da Fox 10 Oct '12

10 Oct '12

Hi all, Since the official bug-tracker at https://bugtrack.alsa-project.org/alsa-bug/ seems to be down (and moreover this appears to be a kernel bug), I have filed a bug at the kernel's bug-tracker last week ( https://bugzilla.kernel.org/show_bug.cgi?id=48381 ). However, it seems to have gone unnoticed thus-far. Quick summary of the issue: After a while of inactivity the sound-card seems to go into a sort of power-saving mode (you can hear a faint 'pop' from the speakers). Before the sound would automatically turn back on again as soon as a program attempted to play sound. However now it seems that after resuming from the power-saving mode the driver thinks that there is always a headphone connected, even when it is not. I think this is what happens because toggling the 'Auto-Mute Mode' (setting it to 'Disabled') in alsamixer allows the speakers to produce sound again. This is all on a laptop (please see the linked bug report for more detailed hardware description). Would a developer please take a look at it? I have bisected the issue down to a commit made by David Henningsson and/or Takashi Iwai: ---8<--------- 80c8bfbe76869bfd6bdf3d260d316e7a32f318c3 is the first bad commit commit 80c8bfbe76869bfd6bdf3d260d316e7a32f318c3 Author: David Henningsson <david.henningsson(a)canonical.com> Date: Mon Jun 4 09:33:51 2012 +0200 ALSA: HDA: Create phantom jacks for fixed inputs and outputs PulseAudio sometimes have difficulties knowing that there is a "Speaker" or "Internal Mic", if they have no individual volume controls or selectors. As a result, only e g "Headphone" might be created for a laptop, but no "Speaker". To help out, create phantom jacks (that are always present, at least for now) for "Speaker", "Internal Mic" etc, in case we detect them. The naming convention is e g "Speaker Phantom Jack". In order not to pollute the /dev/input namespace with even more devices, these are added to the kcontrols only, not the input devices.

[alsa-devel] ASoC: special SPI format for that5173 driver in daisy chain mode
by Christian Schörkhuber 10 Oct '12

10 Oct '12

Hi all, I'm working on an ASoC driver for the THAT5173 microphone preamplifier which is controlled via SPI. When operating in daisy chain mode (4 amps) the desired format is a bit odd: I need to write four 16 bit spi commands (one gain setting for each amp) in a row without raising the chipselect line between commands. That is, I need to write one 64 bit SPI command that is composed of 4 different values (and 4 register addresses which are all 0). Usually I use regmap but I don't see how I can construct such a message with regmap. How can this be done (with or without regmap)? Thanks, Chris

Hm, right, the return value of snd_hda_lock_devices() isn't checked, but I don't understand how this results like above. Basically switching is protected by mutex in vga_switcheroo.c, so the whole operation in the client side should be serialized. In anyway, try the patch below cleanly, and see the spurious message error coming up at which timing. thanks, Takashi --- diff --git a/sound/pci/hda/hda_intel.c b/sound/pci/hda/hda_intel.c index 6833835..4518b05 100644 --- a/sound/pci/hda/hda_intel.c +++ b/sound/pci/hda/hda_intel.c @@ -501,6 +501,7 @@ struct azx { /* VGA-switcheroo setup */ unsigned int use_vga_switcheroo:1; + unsigned int vga_switcheroo_registered:1; unsigned int init_failed:1; /* delayed init failed */ unsigned int disabled:1; /* disabled by VGA-switcher */ @@ -1597,6 +1598,8 @@ static int DELAYED_INIT_MARK azx_codec_create(struct azx *chip, const char *mode int c, codecs, err; int max_slots; + printk(KERN_DEBUG "XXX %s: azx_codec_create entered\n", + pci_name(chip->pci)); memset(&bus_temp, 0, sizeof(bus_temp)); bus_temp.private_data = chip; bus_temp.modelname = model; @@ -1673,6 +1676,8 @@ static int DELAYED_INIT_MARK azx_codec_create(struct azx *chip, const char *mode snd_printk(KERN_ERR SFX "no codecs initialized\n"); return -ENXIO; } + printk(KERN_DEBUG "XXX %s: azx_codec_create done\n", + pci_name(chip->pci)); return 0; } @@ -2615,6 +2620,8 @@ static void azx_vs_set_state(struct pci_dev *pci, return; disabled = (state == VGA_SWITCHEROO_OFF); + printk(KERN_DEBUG "XXX %s: chip->disabled=%d, disabled=%d\n", + pci_name(chip->pci), chip->disabled, disabled); if (chip->disabled == disabled) return; @@ -2638,14 +2645,26 @@ static void azx_vs_set_state(struct pci_dev *pci, disabled ?

[alsa-devel] [PATCH] ALSA: hda - Add missing hda_gen_spec to struct via_spec
by Takashi Iwai 10 Oct '12

10 Oct '12

The commit [4b527b65 ALSA: hda - limit internal mic boost for Asus X202E] introduced the use of auto-parser code, but it forgot to add struct hda_gen_spec at the head of codec->spec which the auto-parser assumes silently.

[alsa-devel] Complex hw buffer with MMAP_COMPLEX?
by Adrian Knoth 09 Oct '12

09 Oct '12

Hi! I'm about to start working on the driver for the new RME MADI FX card with its 194 input and 196 output channels. I've noticed that the device has a rather uncommon hw buffer layout. Let's stick to the input side for the sake of simplicity: 2ch AES, interleaved 8ch MADI 001-008, interleaved 8ch MADI 009-015, interleaved [..] 8ch MADI 184-192, interleaved On the output side, there is another stereo pair for headphones. That is, we're dealing with 25 (or 26 for output) interleaved streams with two or eight channels each. How could we represent such a layout in ALSA, that is, how are we talking to userspace? Would one create subdevices and rejoin them via plughw? Or use MMAP_COMPLEX and then let every application deal with it on its own? It's certainly not a problem to special-case the MADI FX in jackd1 and jackd2, but OTOH, this would require other ALSA apps to do the same (I'm thinking of proprietary custom code). I wonder if we could afford to rearrange the buffers in the driver and expose a single non-interleaved buffer to userspace. WDYT? TIA

[alsa-devel] [PATCH v2] ALSA: ASoC: McASP: add support for 24 bit samples
by Mike Looijmans 09 Oct '12

09 Oct '12

Sorry for the lack of quoting, but I onle get the digest. These are wrong: + case SNDRV_PCM_FORMAT_U24_LE: + case SNDRV_PCM_FORMAT_S24_LE: These pack a 24-bit sample value in a 32-bit word. The codec will send 32 bits to the McASP, and you should transfer 32 bits to the user, not just 24. Hence, SNDRV_PCM_FORMAT_S24_LE must be treated just like SNDRV_PCM_FORMAT_S32_LE. I've tested that on a DA850-alike board with several TLV320AIC3256 codecs, treating them as 3-byte samples will reasult in invalid data.

[alsa-devel] [PATCH] ALSA: hda - remove "Mic Jack Mode" for headset jacks (Latitude Exx30)
by David Henningsson 09 Oct '12

09 Oct '12

Dell Latitude 5x30 and 6x30 series of machines all have a single 4-pin headset jack. Enabling line in mode for such jack is very confusing (you would only get mono input, and would have to use non-standard adapters), so remove the option by default.

If the previous patch fixed, it means that the switching occurred during the device was being probed. Maybe a better approach to register the VGA switcheroo after the proper initialization. The patch below is a revised one. Please give it a try.

[alsa-devel] [PATCH 0/5] McASP changes for more flexibility
by Daniel Mack 09 Oct '12

09 Oct '12

Hi, I've been working on the McASP driver lately to support a board on which an AM33xx SoC is connected to a CS4271 via I2S. The CPU is clock master for both LRCLK and BITCLK, but receives its master clock externally. Some changes were necessary in order to get this playing, as the driver seems to have been used with DSP_B formats only. I couldn't the pateches on any Davinci platform, so I rely on other people to test and see if they break anything. Thanks, Daniel Daniel Mack (5): ALSA: ASoC: enable 192KHz support for McASP ALSA: ASoC: McASP: add support for clock dividers ALSA: ASoC: McASP: add support for 24 bit samples ALSA: ASoC: McASP: make AHCLK direction configurable ALSA: ASoC: McASP: set format parameters in dependence of the DAI format sound/soc/davinci/davinci-evm.c | 5 +++ sound/soc/davinci/davinci-mcasp.c | 87 ++++++++++++++++++++++++++++++++++----- sound/soc/davinci/davinci-mcasp.h | 2 +- sound/soc/davinci/davinci-pcm.c | 16 ++----- 4 files changed, 86 insertions(+), 24 deletions(-) -- 1.7.11.4

[alsa-devel] [PATCH v2 1/2] ARM: imx: clk: Split SSI clock into 'ipg' and 'per'
by Fabio Estevam 09 Oct '12

09 Oct '12

Currently imx ssi driver has been using only the ipg clock as only slave mode is supported. For mx27 it is necessay to provide both 'ipg' and 'per' clocks in order to get ssi functional. This issue was found on mx27 by unselecting the mmc driver from the kernel ,which resulted on a system that could not play audio. When the mmc driver is selected the required 'per2' clock is provided and it allows the ssi to work. Add the required 'per' clock to the mx27 ssi and a dummy one for the other SoCs.

Subject: [PATCH] ASoC: fsi: don't reschedule DMA from an atomic context shdma doesn't support transfer re-scheduling or triggering from callbacks or from atomic context. The fsi driver issues DMA transfers from a tasklet context, which is a bug. To fix it convert tasklet to a work.

[alsa-devel] [PATCH 1/2] ARM: imx: clk: Split SSI clock into 'ipg' and 'per'
by Fabio Estevam 08 Oct '12

08 Oct '12

Currently imx ssi driver has been using only the ipg clock as only slave mode is supported. For mx27 it is necessay to provide both 'ipg' and 'per' clocks in order to get ssi functional. This issue was found on mx27 by unselecting the mmc driver from the kernel ,which resulted on a system that could not play audio. When the mmc driver is selected the required 'per2' clock is provided and it allows the ssi to work. Add the required 'per' clock to the mx27 ssi and a dummy one for the other SoCs.

[alsa-devel] [PATCH] pcm: support for audio timestamps
by Pierre-Louis Bossart 08 Oct '12

08 Oct '12

add new snd_pcm_status_get_audio_htstamp() routine to query the audio timestamps provided by the kernel. This change provides applications with better ways to track elapsed time. Before this patch, applications would subtract queued samples (delay) from written samples, resulting in a 1-2 sample error. Also add snd_pcm_hw_params_supports_audio_wallclock_ts() to query what the hardware supports. TODO: check protocol compatibility?

[alsa-devel] [3.6-rc7] switcheroo race with Intel HDA...
by Daniel J Blueman 08 Oct '12

08 Oct '12

On my Macbook with a discrete Nvidia GPU, there is a race between selecting the integrated GPU and putting the discrete GPU into D3 [1], reliably causing a kernel oops [2]. Introducing a delay of ~1s between the calls prevents this. When the second 'OFF' write path executes, it looks like struct azx at card->private_data hasn't yet been allocated yet [3], so there is likely some locking missing. I'm happy to perform further testing and debug of course...

[alsa-devel] Constant noise on HDA ALC275

Hi there, I've an HDA based chipset in a new Sony Vaio Z (Ivy Bridge). As sound as the system starts and the sound module are loaded, there's a constant noise (shhhhhhht) in the speakers. The noise change a bit if I toggle the mute button, but it's still there. This noise stops as sound as I plug something in the jack port. I've tried to play with HDA Analyzer¹, but I've no clue what to look for, so any hint appreciated.

[alsa-devel] [PATCH] ALSA: aloop - add locking to timer access
by Omair Mohammed Abdullah 08 Oct '12

08 Oct '12

When the loopback timer handler is running, calling del_timer() (for STOP trigger) will not wait for the handler to complete before deactivating the timer. The timer gets rescheduled in the handler as usual. Then a subsequent START trigger will try to start the timer using add_timer() with a timer pending leading to a kernel panic. Serialize the calls to add_timer() and del_timer() using a spin lock to avoid this.

[alsa-devel] [PATCH] ALSA: hda - fix indices on boost volume on Conexant
by David Henningsson 08 Oct '12

08 Oct '12

After the recent patch "ALSA: hda - use both input paths on Conexant auto parser" suddenly we can have more than one "Mic Boost", this happened on Acer Aspire One 722. Therefore we must add the possibility to put an index on this "Mic Boost" just as we do for the other "Mic Boost" earlier in the same function.

[alsa-devel] [PATCH] ALSA: hda - Fix hang caused by race during suspend.
by Dylan Reid 08 Oct '12

08 Oct '12

There was a race condition when the system suspends while hda_power_work is running in the work queue. If system suspend (snd_hda_suspend) happens after the work queue releases power_lock but before it calls hda_call_codec_suspend, codec_suspend runs with power_on=0, causing the codec to power up for register reads, and hanging when it calls cancel_delayed_work_sync from the running work queue. The call chain from the work queue will look like this: hda_power_work <<- power_on = 1, unlock, then power_on cleard by suspend hda_call_codec_suspend hda_set_power_state snd_hda_codec_read codec_exec_verb snd_hda_power_up snd_hda_power_save __snd_hda_power_up cancel_delayed_work_sync <<-- cancelling executing wq Fix this by waiting for the work queue to finish before starting suspend if suspend is not happening on the work queue.

[alsa-devel] [PATCH] ALSA: hda/realtek - Fix detection of ALC271X codec
by Herton Ronaldo Krzesinski 08 Oct '12

08 Oct '12

In commit af741c1 ("ALSA: hda/realtek - Call alc_auto_parse_customize_define() always after fixup"), alc_auto_parse_customize_define was moved after detection of ALC271X. The problem is that detection of ALC271X relies on spec->cdefine.platform_type, and it's set on alc_auto_parse_customize_define. Move the alc_auto_parse_customize_define and its required fixup setup before the block doing the ALC271X and other codec setup.

[alsa-devel] [PATCH 0/10] ALSA: Add DSP firmware loader (v3)
by Ian Minett 08 Oct '12

08 Oct '12

From: Ian Minett <ian_minett(a)creativelabs.com> Hi, thanks for the response. I've resubmitted the patch series with updates to the ones that needed altering based on the feedback. The MODULE_FIRMWARE line has been shifted to the firmware loading patch, DSP download is now guarded by the config switch and code changes that were bundled in with the previous comments patch have moved to a new patch. Also, hda_stream_format has been removed. Regarding the SCP packet endianness, the DSP image requires data to be sent as little-endian, so we may need to swizzle data being sent to the DSP before the transfer. Is there a recommended or standard way of detecting and handling the case of running on big-endian architectures? >Does the firmware on chip survive after S3?

Since commit 0998d0631001288a5974afc0b2a5f568bcdecb4d, 'device-core: Ensure drvdata = NULL when no driver is bound', the Amstrad Delta sound card no longer initializes correctly due to drvdata reset to NULL by an upper layer before the codec device, required for successful card setup, is registered.

[alsa-devel] snd_hwdep_open() as non-root user
by Rafal Powierski 04 Oct '12

04 Oct '12

Developers, I would like to access pin verb hda interface using snd_hwdep_open() function. It works fine if I run as root. I hope there is a way to configure my kubuntu so I can do it as non-root user (e.g. debugging) so far, I have been trying changing access flags for devices in /dev/snd/ directory to crwxrwxrwx no plus character. It did not change my privileges for snd_hwdep_open() - still returns –13. I assume that the device-file responsible is /dev/snd/hwC1D0, the same as parameter given to “hda-verb” program. I am developing a new hardware, using HDA codec. Please help

The patches I just sent out are only for Davinci and change the SRAM functions to genalloc in the mcasp driver. They work just fine on OMAP of course, as the code is disabled in there. Daniel

[alsa-devel] ASoC: Fix wrong include for McPDM
by Tony Lindgren 04 Oct '12

04 Oct '12

McPDM needs platt/cpu.h for omap_rev and not omap_hwmod.h. Drivers must not include omap_hwmod.h at, it will be private to mach-omap2 soon. Fix the problem before other drivers will also start including omap_hwmod.h. Note that also plat/cpu.h will be going away, so the omap_rev check needs to be replaced with mcpdm-watchdog flag from platform_data or DT. Signed-off-by: Tony Lindgren <tony(a)atomide.com> --- Can you guys please queue this as fix for -rc1? This removes and unnecessary dependency for making omap_hwmod.h local to mach-omap2.

Yes - by "later" I just meant in a subsequent patch. But you're probably right, we can also do that first. I'm looking at that right now and the problem seems that we don't have a sane way to dynamically look up gen_pools independently of the actual run-time platform. All users of gen_pools seem to know which platform they run on and access a platform-specific pool. So I don't currently see how we could implement multi-platform code, gen_pools are fine but don't solve the problem here. Would it be an idea to add a char* member to gen_pools and a function that can be used to dynamically look it up again? If a buffer with a certain name exists, we can use it and install that ping-pong buffer, otherwise we just don't. While that would be easy to do, it's a tree-wide change. Is there a better way that I miss? Daniel

[alsa-devel] [PATCH 1/2] ALSA: core: add hooks for audio timestamps
by Pierre-Louis Bossart 30 Sep '12

30 Sep '12

ALSA did not provide any direct means to infer the audio time for A/V sync and system/audio time correlations (eg. PulseAudio). Applications had to track the number of samples read/written and add/subtract the number of samples queued in the ring buffer. This accounting led to small errors, typically several samples, due to the two-step process. Computing the audio time in the kernel is more direct, as all the information is available in the same routines. Also add new .audio_wallclock routine to enable fine-grain synchronization between monotonic system time and audio hardware time. Using the wallclock, if supported in hardware, allows for a much better sub-microsecond precision and a common drift tracking for all devices sharing the same wall clock (master clock).

[alsa-devel] snd_had_intel turning off internal speakers by going to power state D3
by Jeff Robins 29 Sep '12

29 Sep '12

Hello, I have a Toshiba Satellite C655D with Mageia 2 and I have a problem where the internal speakers eventually stop producing sound, but the headphones still work. After doing a bit of research and running alsa-info (attached) I figured out that one of the parts of the sound card had gone into a D3 power state. Removing and then reloading the snd_hda_intel module fixed the problem, but then the sound would turn off again. I was able to find a post in alsa-users where someone else came up with a better solution using hda-verb to reset the power state: http://www.mail-archive.com/alsa-user@lists.sourceforge.net/msg28769.html I also found a thread in the gentoo forums where other people are having the same problem. One of them has kernel 3.5.0: http://forums.gentoo.org/viewtopic-t-932038.html?sid=2bee6543c63f2342057c71… I'm open to compiling my own alsa and helping out in any way I can. Please let me know what I can do. Mageia bug report for completeness: https://bugs.mageia.org/show_bug.cgi?id=7292 Thank you, Jeff

[alsa-devel] Problem with AC97 and WM9714 on S3C6410
by Andrey Gusakov 29 Sep '12

29 Sep '12

Hi. I'm working with mini6410 devkit/demoboard. Itry to move forward from old kernel to last samsung kernel from git. I run into interesting problem with ALSA and WM9714 codec. On kernel boot I see some activity on AC97 bus, but then BCLK and SYNC stops. As i figure out clock stops after write to WM9714 register 0x00. As I understand it's a reset comand. But it brokes all communication. No blayback or control regiter read/write posible after. And there is no reset or warm_reset commands after it. If i filter out all writes to register 0x00 in samsung AC97 driver, everything seems to work corect. But it's a dirty fix. I use dump_stack() to collect some aditional info. That what i got: Try to reset codec! (write at 0x00) [<c0014978>] (unwind_backtrace+0x0/0xf4) from [<c035caf0>] (ac97_write+0x4c/0x64) [<c035caf0>] (ac97_write+0x4c/0x64) from [<c034d00c>] (snd_soc_write+0xc/0x10) [<c034d00c>] (snd_soc_write+0xc/0x10) from [<c035355c>] (soc_widget_update_bits_locked+0x114/0x190) [<c035355c>] (soc_widget_update_bits_locked+0x114/0x190) from [<c0353830>] (dapm_seq_run_coalesced+0x114/0x16c) [<c0353830>] (dapm_seq_run_coalesced+0x114/0x16c) from [<c0353b88>] (dapm_seq_run+0x300/0x4a0) [<c0353b88>] (dapm_seq_run+0x300/0x4a0) from [<c0354be0>] (dapm_power_widgets+0x404/0x600) [<c0354be0>] (dapm_power_widgets+0x404/0x600) from [<c03577ec>] (snd_soc_dapm_new_widgets+0x2ac/0x6ac) [<c03577ec>] (snd_soc_dapm_new_widgets+0x2ac/0x6ac) from [<c034f940>] (soc_post_component_init+0x44/0x27c) [<c034f940>] (soc_post_component_init+0x44/0x27c) from [<c03513f4>] (snd_soc_register_card+0xc44/0x1a00) [<c03513f4>] (snd_soc_register_card+0xc44/0x1a00) from [<c03521e8>] (soc_probe+0x38/0x64) [<c03521e8>] (soc_probe+0x38/0x64) from [<c025f9d8>] (platform_drv_probe+0x18/0x1c) [<c025f9d8>] (platform_drv_probe+0x18/0x1c) from [<c025e518>] (driver_probe_device+0x78/0x1fc) [<c025e518>] (driver_probe_device+0x78/0x1fc) from [<c025cd9c>] (bus_for_each_drv+0x60/0x8c) [<c025cd9c>] (bus_for_each_drv+0x60/0x8c) from [<c025e810>] (device_attach+0x80/0x98) [<c025e810>] (device_attach+0x80/0x98) from [<c025d8bc>] (bus_probe_device+0x84/0xac) [<c025d8bc>] (bus_probe_device+0x84/0xac) from [<c025c6ec>] (device_add+0x5b0/0x67c) [<c025c6ec>] (device_add+0x5b0/0x67c) from [<c025ffa8>] (platform_device_add+0xf4/0x20c) [<c025ffa8>] (platform_device_add+0xf4/0x20c) from [<c060b3a4>] (mini6410_init+0x60/0xa0) [<c060b3a4>] (mini6410_init+0x60/0xa0) from [<c00085d0>] (do_one_initcall+0x34/0x178) [<c00085d0>] (do_one_initcall+0x34/0x178) from [<c05f3310>] (kernel_init+0xe0/0x1ac) [<c05f3310>] (kernel_init+0xe0/0x1ac) from [<c000f848>] (kernel_thread_exit+0x0/0x8) I'm begginer in kernel programing and have no enouth experience to figure what's happening. Can any one help with this problem? Thank you.

[alsa-devel] imx28 pcm issue
by George Stefan 29 Sep '12

29 Sep '12

Hi! I have an issues with a modem connected to the SAIF port of an imx28. I have the following configuration running on the modem: -modem is slave(but still have to fix the clock at 256 khz) -"short frame" sync. PCM data is always formatted as 16-bit uncompressed two’s complement. Also, all PCM data and frame synchronization signals are written to the PCM bus on the rising clock edge and read on the falling edge. - 16 bits liniar sample, MSB first. On the imx side i have the following configuration priv->sysclk = 512 * rate; snd_soc_dai_set_clkdiv(cpu_dai, IMX_SSP_SYS_MCLK, 32); dai_format = SND_SOC_DAIFMT_DSP_A | SND_SOC_DAIFMT_IB_NF | SND_SOC_DAIFMT_CBM_CFM; snd_soc_dai_set_sysclk(cpu_dai, IMX_SSP_SYS_CLK, priv->sysclk, SND_SOC_CLOCK_OUT); The modem has the 2 options for testing, either outputing a tone or an audio loop. My problem is that i cannot receive anything else but noise. arecord -f S16_LE -c2 -r8000 test.wav hexdump -C test.wav 00000000 52 49 46 46 24 c4 09 00 57 41 56 45 66 6d 74 20 |RIFF$...WAVEfmt | 00000010 10 00 00 00 01 00 02 00 40 1f 00 00 00 7d 00 00 |........@....}..| 00000020 04 00 10 00 64 61 74 61 00 c4 09 00 00 00 00 00 |....data........| 00000030 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 |................| * 00040f10 00 00 00 00 f0 03 00 00 00 00 00 00 00 00 00 00 |................| 00040f20 00 00 0f 00 ff ff ff ff ff ff f0 ff fc 00 00 00 |................| 00040f30 00 00 00 00 00 00 00 00 00 00 ff 01 ff ff ff ff |................| 00040f40 00 fc 03 00 00 e0 00 00 00 00 00 00 00 00 00 00 |................| 00040f50 00 00 ff 1f ff ff ff ff 00 ff ff 1f 00 f8 00 00 |................| 00040f60 00 00 00 00 00 00 00 00 03 00 ff ff ff ff ff ff |................| 00040f70 81 ff ff ff 00 00 00 00 00 00 00 00 00 00 00 00 |................| 00040f80 3f 00 ff ff ff ff 80 ff 00 00 00 00 00 00 00 00 |?...............| When i select the audio loop mode, play a wav sample, and record it at the same time, i hear noise every time i play that wav and silence between them(so something is moving out there) Do you have any suggestions on why this is happening?

[alsa-devel] Delay calculations for USB audio?
by David Henningsson 28 Sep '12

28 Sep '12

Hi, While researching some crackling audio problem, I noticed that I got these messages in my dmesg: delay: estimated 0, actual 384 delay: estimated 384, actual 768 They come at every start of playback. I want to understand this stuff, so I tried to dig a little. It looks like the endpoint is started in the prepare stage, so between prepare and trigger, silence data will be sent. First question: Isn't this messing up the delay calculations? If you fill some "urb buffer" [1] with silence, depending on the urb buffer size, delay calculation should take this into account for proper lipsync. I mean, the USB audio device would first have to play all the silence data before it could start the audio data, right? (And how big is this buffer anyway?) Second question: This also means that some of the silence packets will go through retire_playback_urb, right? Isn't this also messing with the delay calculation? (Oh, and btw, if you have an idea of the crackling/distorted USB audio, let me know. I'm using a standard Logitech USB Headset, using speaker-test -c 2 -D plughw:Headset -t sine -r 48000 I can make the problem go away using any of these options: * Booting a 3.2 kernel - I've tried 3.5, 3.6-rc7 and 3.2 * Choosing the 44100 sample rate instead of the default of 48000 * Selecting the outer USB port instead of the inner one. Yes, there are two USB ports next to each other, and this only happens on one of them. (!)) -- David Henningsson, Canonical Ltd. https://launchpad.net/~diwic [1] maybe there's a better name for it?

Also, I wonder if this shouldn't wait for the forthcoming standardized DT DMA bindings (or perhaps document custom bindings that are identical to the new standardized bindings)? Otherwise, the DMA stuff will all have to be redefined again. Apparently it's hoped the bindings will be in 3.7, or if not there, in 3.8.

[alsa-devel] [PATCH] pcm: support for audio timestamps
by Pierre-Louis Bossart 28 Sep '12

28 Sep '12

add new snd_pcm_status_get_audio_htstamp() routine to query the audio timestamps provided by the kernel. This change provides applications with better ways to track elapsed time. Before this patch, applications would subtract queued samples (delay) from written samples, resulting in a 1-2 sample error. Also add snd_pcm_hw_params_supports_audio_wallclock_ts() to query what the hardware supports. TODO: check protocol compatibility?

[alsa-devel] setup_dig_out_stream() resets the SPDIF steam causing clicks
by Laurence Darby 28 Sep '12

28 Sep '12

Hi, I'm playing audio via SPDIF, with a Realtek codec, and there's a problem that whenever audio is started, or seeking in every music player I tried, the DAC lost sync briefly, which made it 'click' when it muted and unmuted itself. I recently upgraded the DAC, and this problem only happened with the new DAC, but not the old one, I don't know (or really care) why - the old DAC had much worse problems. Here's what I did to fix this: diff -up linux-3.5.4/sound/pci/hda/hda_codec.c.orig linux-3.5.4/sound/pci/hda/hda_codec.c --- linux-3.5.4/sound/pci/hda/hda_codec.c.orig 2012-09-28 00:13:25.000000000 +0100 +++ linux-3.5.4/sound/pci/hda/hda_codec.c 2012-09-28 00:39:31.000000000 +0100 @@ -4693,9 +4693,11 @@ static void setup_dig_out_stream(struct format); } /* turn on again (if needed) */ - if (codec->spdif_status_reset && (spdif->ctls & AC_DIG1_ENABLE)) + if (codec->spdif_status_reset && (spdif->ctls & AC_DIG1_ENABLE)) { set_dig_out_convert(codec, nid, spdif->ctls & 0xff, -1); + codec->spdif_status_reset=0; + } } static void cleanup_dig_out_stream(struct hda_codec *codec, hda_nid_t nid) That makes SPDIF turn off and on just once when sound is first played (i.e. it clicks once then, then no more). In patch_realtek.c it's got this: /* FIXME: do we need this for all Realtek codec models? */ codec->spdif_status_reset = 1; If I set that to 0, then the left channel doesn't initialize and is silent, so the reset really does need to happen once (for my realtek model anyway, I don't know how to find out what that would be?) So, is the above an acceptable fix? Regards, Laurence

[alsa-devel] ASoC on today's linux-next: dma_alloc_writecombine() failing at least on OMAP platforms
by Peter Ujfalusi 27 Sep '12

27 Sep '12

Hello, I tried today's linux-next on OMAP platform and audio is not probing because dma_alloc_writecombine() fails to get the area. My linux-next from two days ago works OK and I don't see anything directly connected to OMAP which can cause this failure. Can someone try linux-next on non OMAP platform to see if dma_alloc_writecombine() works there? Meanwhile I'll try to find the reason why it fails for me. Thanks, Péter

[alsa-devel] Merging alsa-driver and alsa-kmirror to one GIT repo
by Jaroslav Kysela 26 Sep '12

26 Sep '12

Hi all, I believe, it's time to manage only one GIT repository for the alsa-driver package now. The merge has benefits mainly for the end users - bisecting may work, the correlation between kernel sources and our out-of-kernel build framework becomes more strong. I merged the alsa-driver and alsa-kmirror repos with full history. I also added some code changes to enable the "build-in" mirror tree in Makefile and gitcompile from v1.0.18 (but I don't think that it will be used). The structure of new repository is similar, but the kernel mirrored code is located in the mirror/ subdirectory. The paths are exactly same as in the Linux kernel tree, so possible patches can be applied without any path modifications. Of course, we may create a bash script to do proper and full cherry-picks between kernel and mirrored trees (comments, author, dates). New temporary repository has name alsa-driver.new: http://git.alsa-project.org/?p=alsa-driver.new.git;a=summary The another difference is that the releases are now branches not tags. It allows me to do quick fixes out of the standard development or separate the main development in the release time window (to not include some very new code). The previous branches won't contain probably any additional commits, but it's probably better to play with only one reference scheme. I think that the change from alsa-driver.git to alsa-driver.new.git should be quick. Please, report any objections or acks now. Schedule: When accepted, I will rename the original alsa-driver.git repository to alsa-driver.old.git and move alsa-driver.new.git to alsa-driver.git quickly. 1.0.26 release: This was my last big change (with the ALSA server upgrade) which blocked me to do the 1.0.26 release. I'm going to create new release after the repos switch ASAP. Jaroslav -- Jaroslav Kysela <perex(a)perex.cz> Linux Kernel Sound Maintainer ALSA Project; Red Hat, Inc.

[alsa-devel] [PATCH 1/2] ASoC: fsl_ssi: Let it understand mono
by Fabio Estevam 25 Sep '12

25 Sep '12

Currently there are two variants for the FSL SSI driver: - fsl_ssi.c is the device tree driver version for the FSL SSI driver (used by PowerPC and i.MX) - imx-ssi.c is the non device tree version that runs on some i.MX processors that are not yet converted to dt. Commit 0865a7 (ASoC: imx-ssi: Remove mono support) attempted to fix mono audio playback issue inside imx-ssi.c, which according to 104c22 (ASoC: Revert 'ASoC: imx-ssi: Remove mono support' ) caused problem on another i.MX platform. The original mono playback issue was later fixed inside the mc13783 codec driver. As the long term goal is to move other platforms to dt, then fsl_ssi needs to have the same fix for channels_min as in imx-ssi.

[alsa-devel] [PATCH] ALSA: hda - Remove ignore_misc_bit
by David Henningsson 25 Sep '12

25 Sep '12

The purpose of this flag is unclear. If the problem is that some machines have broken misc/NO_PRESENCE bits, they should be fixed by pin fixups. In addition, this causes jack detection functionality to be flawed on the M31EI, where there are two jacks without jack detection (which is properly marked as NO_PRESENCE), but due to ignore_misc_bit, these jacks are instead being reported as being present but always unplugged.

[alsa-devel] [PATCH v3 00/15] ASoC: OMAP: Convert to use dmaengine
by Peter Ujfalusi 25 Sep '12

25 Sep '12

Hello, Changes since v2: - As it has been discussed the no_wakeup parameter has been replaced with flags for the dmaengine APIs Changes since v1: - Support for pause/resume for OMAP audio via dmaengine - dmaengine: support for NO_PERIOD_WAKEUP in cyclic mode - OMAP to keep supporting NO_PERIOD_WAKEUP for audio - Other plaforms can also try to enable this mode since we have now generic interface to do so. This series will switch the OMAP audio to use dmaengine. The final patch which does the switch was based on Russell King's earlier patch. The first 10 patch is to prepare the OMAP audio drivers for a smooth change to dmaengine: - sDMA FRAME sync mode is removed and replaced with PACKET mode - dai drivers no longer need to configure sDMA sync mode - dai drivers does not need to specify the DMA word length - with the exception of the omap-hdmi driver which requires 32bit word length regardless of the audio format in use - the McPDM driver used (to my surprise) hackish way of getting the DMA channel and address - via defines from some header files After the conversion OMAP audio support should have the same features as before, no regressions expected. I have tested the series on: - BeagleBoard (audio via McBSP): - aplay/arecord.

[alsa-devel] HD Audio with 'mute light'
by Arnout Engelen 24 Sep '12

24 Sep '12

Hi, I've got a laptop with a HD Audio onboard sound card: the CX20590. It seems like this card has a sort of 'hardware mute state': the 'mute button' has a light, and when this light is on, no sound is heard, regardless of whether or not the channel is muted in the ALSA mixer. The hardware mute button switches the 'hardware mute state', and also sends a keyboard event which I can use to also update the ALSA mixer mute. This doesn't, however, work the other way around: I haven't found any way yet to manipulate the 'hardware mute state' from software. Looking with hda_analyzer, I notice this card has a 'Vendor Defined Widget'. Might this be something that could be used to manipulate the hardware mute state? I can use hda-verb but I wouldn't know how to discover which verb to use. Anything else to try? Attached is the codec info. Kind regards, Arnout

[alsa-devel] Dynamic HDMI PCM creation
by Takashi Iwai 23 Sep '12

23 Sep '12

Hi David, as we discussed at Plumbers, I tried some hack to create/delete HDMI/DP PCM stream per hotplug/unplug. Test patches are found in sound-unstable git tree topic/hdmi-dynamic-pcm branch git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-unstable.git The patches are all small and easy, but it's still in a pretty rough cut. It won't handle some cases, e.g. unplug during suspend, or such, I'm afraid. After all, it's just a test. With these patches, the PCM device appears and disappears properly upon HDMI/DP hotplug/unplug on my system. On mine, it appears as /dev/snd/pcmC0D8 as it's an Intel on-board. So far, so good. Now the problem is that PA gets confused when this happens. It can switch to HDMI/DP, but then the analog output disappears from PA's profile. You cannot switch back to analog output after that, even after you unplug HDMI/DP cable. Or, it might be my PA version... I'll check newer one. But it'd be good if you also check in your side. thanks, Takashi

[alsa-devel] [PATCH v2 00/34] i.MX multi-platform support
by Shawn Guo 22 Sep '12

22 Sep '12

Here is the second post, which should have addressed the comments that reviewers put on v1. It's available on branch below. git://git.linaro.org/people/shawnguo/linux-2.6.git imx/multi-platform-v2 And it's based on the following branches. calxeda/multi-plat arm-soc/multiplatform/platform-data arm-soc/multiplatform/smp_ops arm-soc/imx/cleanup arm-soc/imx/dt sound/for-3.7 Subsystem maintainers, I plan to send the whole series for 3.7 via arm-soc tree. Please let me know if you have problem with that. Thanks.

[alsa-devel] [PATCH v4 00/14] MFD/ASoC/Input: twl4030-audio submodule DT support
by Peter Ujfalusi 22 Sep '12

22 Sep '12

Hello, Generated on top of: git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git topic/omap Changes since v3: - Added Acked-by from Tony and Dmitry - Removed #ifdef around of_find_node_by_name() in the drivers Changed since v2: - Added commit message to patch 2 (as Tero requested it) - Fixed patch 6 (dt: Add empty...) since the previous patch caused x86_64 build to fail due to missing struct before device_node. Changes since v1: - Get the MCLK frequencey from twl-core driver (via new API) - hs_extmute_disable_level parameter has been removed - empty of_find_node_by_name() in of.h for !CONFIG_OF builds Mark: the extmute GPIO handling (when it is used) remained in the codec driver for now. I can think more on how to add support for this type of mute control. If you can point me to other codec needing this it would help on designing something which is common enough for other users. As for now I have a separate series to add GPIO controlled output amps (hp/spk). I will send that to review soon. Currently this piece of code does not work when booted with device tree since I have done it on n900 which has the GPIO numbers as defines. I need to revisit the aproach on how to do it in a dynamic way. Introl mail from v1: The following series adds DT support for the twl4030 audio submodule which provides audio codec and vibra functionality. The MFD core driver is probed via DT, it will create the needed child devices based on the provided information in the DT blob. Child drivers (vibra, ASoC codec) will parse the core's node if needed to get the needed parameters for their configuration. In the ASoC codec driver the hs_extmute callback (which was used to toggle a GPIO line) has been removed. The codec driver will receive the GPIO number (if it is needed on the platform). If the series is OK (and no objections from the maintainers), it would be good if this can go via audio. Changed files are well contained within the twl4030-audio stack so I do not expect merge issues later. The series has been tested on BeagleBoard (with the McBSP DT series, and with the upcoming DT audio support for BeagleBoard).

[alsa-devel] [PATCH 1/3] ALSA: hda - force use of SSYNC bits
by Pierre-Louis Bossart 22 Sep '12

22 Sep '12

SSYNC bits are typically used to start multiple streams synchronously. It makes sense to use them for a single stream for a more predictable startup sequence. The transfers only start once the DMA and FIFOs are ready. This results in a better correlation between timestamps and number of samples played. Credits to Kar Leong Wang for suggesting this improvement.

[alsa-devel] line-out mute on "phantom" HP jack (Via codec)
by Herton Ronaldo Krzesinski 22 Sep '12

22 Sep '12

Hi, On Via codecs reported on https://bugs.launchpad.net/bugs/1052499, while investigating the report, it can be seen that on Headphone pin the plug is not detectable (NO_PRESENCE). It could be that front panel is AC97 wiring or something else, I don't know. But it makes the jack detection handling code to add the headphone jack as "phantom", which makes snd_hda_jack_detect return headphone jack as always present (commit 80c8bfbe768 is applied/cherry-picked on the reported kernel). Thus after jacks are added, the automute code will always detect HP as present, and keep muted all line-outs. The proposed solution following this is using is_jack_detectable inside via_hp_automute to handle this, other codecs seem to use also is_jack_detectable at the moment in similar situations. Other approach could be also to not report presence on phantom jacks with HP or Line Outs. -- []'s Herton

I guess your machine has either a HDMI or a DP output, no? If it has, IEC958 is a mandatory control for the audio output over such a digital interface. "Digital" is likely the volume control created by alsa-lib, so it's no driver issue, and you can safely ignore it.

[alsa-devel] Infinite loop in snd_pcm_hw_htimestamp() for capture PCMs?
by Andrew Eikum 21 Sep '12

21 Sep '12

Hi folks, I've found some unexpected behavior in alsa-lib. The attached program uses 100% CPU in an infinite loop, when I'd expect it to return either an error or a valid htimestamp. I believe the loop occurs in <src/pcm/pcm_hw.c:snd_pcm_hw_htimestamp()>. Am I not supposed to call htimestamp() on this type of PCM? Is the PCM still in an invalid state when htimestamp() is called? Card: HDA ATI SB Chip: Realtek ALC889 Happy for any insight. Andrew

[alsa-devel] [PATCH] ASoC: wm8960: remove 'dres' field from platform data structure
by Timur Tabi 21 Sep '12

21 Sep '12

The 'dres' field (discharge resistance for headphone outputs) is no longer used in the driver, so remove it. It was used in the original version of the driver when entering standby from off, but we stopped using it when we switched from having a single startup sequence to having separate cap and capless sequences.

[alsa-devel] HD-audio runtime->delay accounting
by Takashi Iwai 21 Sep '12

21 Sep '12

Hi, recently Pierre questioned about the validity of COMBO positioning mode, and it turned out that the position reporting can be handled better if we take the difference between LPIB and DMAPOS as runtime->delay. (In short, LPIB points the position where the data fed to the codec, and DMAPOS points the data fetched to DMA.) We cooked up a test patch below and it seems working well on a few machines I've tested. I think we might have still chance to put this into 3.7, as this would be a good improvement. The patch below is a combined work of two fixes: fixing the better stream start by always using SSYNC bit, and adjusting the position and runtime->delay. Of course, the biggest question is the test coverage. David, could you check whether this doesn't break so much on (some) machines you can test? Of course, if any other people can test it, it'll be a great help, too. The patch should be applied to the latest sound.git tree master branch, but it should be applicable (and easily resolvable) for older versions. The patch extends this new mode only for recent Intel chips, just to be sure. thanks, Takashi --- diff --git a/sound/pci/hda/hda_intel.c b/sound/pci/hda/hda_intel.c index 66fefd1..b1d99d0 100644 --- a/sound/pci/hda/hda_intel.c +++ b/sound/pci/hda/hda_intel.c @@ -555,6 +555,7 @@ enum { #define AZX_DCAPS_ALIGN_BUFSIZE (1 << 22) /* buffer size alignment */ #define AZX_DCAPS_4K_BDLE_BOUNDARY (1 << 23) /* BDLE in 4k boundary */ #define AZX_DCAPS_POSFIX_COMBO (1 << 24) /* Use COMBO as default */ +#define AZX_DCAPS_COUNT_LPIB_DELAY (1 << 25) /* Take LPIB as delay */ /* quirks for ATI SB / AMD Hudson */ #define AZX_DCAPS_PRESET_ATI_SB \ @@ -2003,14 +2004,14 @@ static int azx_pcm_trigger(struct snd_pcm_substream *substream, int cmd) } spin_lock(&chip->reg_lock);

[alsa-devel] [RFC PATCH v3 0/5] snd-ice1712: Add Philips PSC724 Ultimate Edge
by Ondrej Zary 20 Sep '12

20 Sep '12

Hello, this is third attempt to add Philips PSC724 Ultimate Edge sound card support to snd-ice1712 driver. Unlike other snd-ice1712 subdrivers, the codec code is splitted into separate files, reusable by other ice1712 subdrivers. Working: all analog outputs (front, rear, center+lfe, headphone) and inputs (front mic, rear mic, line, cd, aux), mixer, headphone jack detection, suspend/resume Currently untested: SPDIF Buggy: switching AGC mode in mixer causes alsamixer to crash - looks like it does not like notifications about control activating/deactivating

[alsa-devel] [PATCH 08/29] ARM: OMAP2+: Make board-zoom.h local
by Tony Lindgren 20 Sep '12

20 Sep '12

This can be local to mach-omap2 after we rip out the messed up extmute stuff from board-zoom-peripherals.c that's all over the place and probably does not even work because of all the hardcoded GPIO numbers. I also suggest ASoC gusy remove all extmute handling from sound/soc/codecs/twl4030.c unless it's been tested to work and implemented in a saner way.

[alsa-devel] [PATCH] ALSA: hda - use both input paths on Conexant auto parser
by David Henningsson 20 Sep '12

20 Sep '12

On the Thinkpad W520 - and probably several other machines with Conexant 506x chips - the Dock Mic and Mic are connected to the same two selector nodes. This patch will make Dock Mic take one selector node and Mic take the other, when possible. Without the patch, both paths would take the first selector, leading to the normal Mic's volume being controlled by "Dock Mic Boost". (On other machines, this could instead fixup similar problems between Mic and Line In, for example.)

[alsa-devel] [PATCH 07/22] ASoC: Ux500: Initialise PCM from MSP probe rather than as a device
by Lee Jones 20 Sep '12

20 Sep '12

The PCM is a pseudo-device. It doesn't have any of it's own registers or hardware. It rather acts as a layer of abstraction for DMA transfers. Hence, instead of classifying it as a device in its own right, we call the initialisation from the MSP driver.
