[alsa-devel] Bug report: Sound skipping/stuttering every 5-20 minutes
by darknessdescends＠tutanota.com 16 May '16

16 May '16

My sound skips/stutters for about half a second (certainly no more than 1 second) on average every 5-20 minutes. I initially had no sound on this computer with Ubuntu 14.04, which is probably because Ubuntu 14.04 has an outdated version of Alsa. I then tested with a live disc of Ubuntu 16.04 (before official release date), which did give me sound. At this point, I installed the the latest version of Alsa onto Ubuntu 14.04 from here (because 16.04 wasn't officially released at the time and I didn't want to take chances with an unstable system): https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS Sound immediately worked with the latest version of Alsa's driver (March 24, 2016 at the time) on Ubuntu 14.04. However, it came with a cost: this stuttering problem. I then retested with the live disc of Ubuntu 16.04 (this time after the official release date), which also produced sound but with the exact same stuttering problem. I found that on Ubuntu 14.04, the stuttering problem remains unfixed since the March 24, 2016 release of the Alsa daily driver until at least the version I have installed in this bug report. These facts strongly suggest an Alsa problem: 1. The problem does not occur at all on Windows, thus ruling out the possibility of a hardware problem. 2. I had no sound at all before installing the Alsa daily drivers, but did have stuttering sound after installing them. 3. The problem persists on Ubuntu 16.04, which suggests the problem is specific to the driver rather than the operating system. 4. The problem occurs whether playing a locally stored media file with a media player installed on my computer or watching an online video, thus ruling out the possibility that the problem is due to a single browser or plugin issue. 5. Is my hardware too new? Probably not. Here are the results of running "grep "Codec:" /proc/asound/card*/codec*": /proc/asound/card0/codec#0:Codec: Realtek ALC891 /proc/asound/card1/codec#0:Codec: Nvidia Generic The fact that my card is identified by vendor and chip name rather than ID as specified at https://wiki.ubuntu.com/Audio/HDAGeneric suggests that my hardware is supported. By the way, I'm using the Realtek, not the Nvidia HDMI. I've tried disabling all unnecessary channels under alsamixer, but that didn't fix the problem. I tried all 3 potential fixes at https://wiki.ubuntu.com/Audio/PositionReporting, but none worked either. I commented my /etc/modprobe.d/alsa-base.conf and /etc/pulse/default.pa files appropriately to show what I tried (I know at least alsa-base.conf is uploaded). I really appreciate the effort you developers put in to supporting sound on Linux. I hope my bug report will help fix this problem for a lot of users on Skylake systems. More information and attached files can be found here (I filed a bug report with Ubuntu before I found out about Alsa's developer mailing list): https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1580744

[alsa-devel] Porting WM8904 codec to new board - trying to get ALSA aplay going
by Nounou Dadoun 16 May '16

16 May '16

Not sure whether this should go to the dev or users list (or somewhere in between) so I'll start off trying both. I'm trying to port a wm8904 audio driver/codec to a new board and the new board uses a device tree configuration which is new to both me and our project. The target arm board uses a linux 3-10 kernel, I have the wm8904 on the i2c bus and configured the Sound in the device tree to use an i2s controller. The codec and platform driver are modprobed on startup. I've made a lot of progress, I (finally!) have the codec loading/modprobed properly and the platform driver probed and successful (up to a point), so I have in the serial log: [ 6.766524] snd_soc_card_avigilon sound.3: wm8904-hifi <-> 6000a000.i2s mapping ok And at the console: # aplay -l **** List of PLAYBACK Hardware Devices **** card 0: AVIGILONWM8904 [AVIGILON-WM8904], device 0: WM8904-STREAM wm8904-hifi-0 [] Subdevices: 1/1 Subdevice #0: subdevice #0 # ls /proc/asound/ AVIGILONWM8904 card0 cards devices pcm timers version # cat /proc/asound/cards 0 [AVIGILONWM8904 ]: AVIGILON-WM8904 - AVIGILON-WM8904 AVIGILON-WM8904 But when I try to play a wave file, I get (no sound and): # aplay -v audiocheck.net_sin_220Hz_0dBFS_10s.wav Playing WAVE 'audiocheck.net_sin_220Hz_0dBFS_10s.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Mono aplay: set_params:1297: Unable to install hw params: ACCESS: RW_INTERLEAVED FORMAT: S16_LE SUBFORMAT: STD SAMPLE_BITS: 16 FRAME_BITS: 16 CHANNELS: 1 RATE: 44100 PERIOD_TIME: (46439 46440) PERIOD_SIZE: 2048 PERIOD_BYTES: 4096 PERIODS: 11 BUFFER_TIME: (510839 510840) BUFFER_SIZE: 22528 BUFFER_BYTES: 45056 TICK_TIME: 0 # But (encouragingly) when I try this, I get my trace statement from the platform driver: [ 3794.140675] Calling avigilon_board_startup in the serial log. >From the canonical/generic platform driver file, the soc_snd_probe probe routine seems to be doing a bunch of dai link configuration and other stuff (including reading values out of the device tree) which I'm not currently doing in my equivalent probe routine. (And which I haven't been able to find any documentation for.) So a few questions: Am I correct in assuming that the " Unable to install hw params " error indicates that something is missing at the board probe level? Any suggestions about what's necessary to get it going? Is there any documentation about what the board probe should be doing to set up the hardware for playback properly? Is the board startup routine required to do anything? (It didn't in the non-device tree implementation which I'm taking it from.) Any other useful hints or pointers? Is there a question which I should be asking which I'm not? Thanks in advance for any assistance which you might be able to provide, my progress to date has involved a lot of trial and error and has been much slower than I would like! ...

[alsa-devel] ALSA Device Driver Programming
by Fredrick Cantabery 16 May '16

16 May '16

First off, let me state that I hope that I am not inappropriately infringing upon anyone's time and hope this post is proper for the audience. Language Acoustics is a startup loudspeaker company who is trying to trying to develop an ALSA compliant sound card driver to support various hardware devices in Linux on an x86 based platform. The sound devices will be multi-channel with both analog and digital inputs and outputs. This has proven to be a difficult hurdle for us and we are reaching out to you to see if you might know someone who might be able to assist in the development effort. We view this as a freelance opportunity for someone but could be interested in other alternative partnerships if someone has interest. Experience in sample rate conversion and the JACK audio connection kit would be highly desirable as well. Thank you for time and consideration. Rick Cantabery Owner, Language Acoustics

[alsa-devel] ADAU1761 default register value problem
by Ricard Wanderlof 16 May '16

16 May '16

Hi Lars, A while ago I posted a question to the list regarding the default values set up for the ADAU1761 (and similar CODECs), but I didn't get a response. I really need to try and figure out a way forward here though so I'll bring this up again. The problem I have is that the driver assumes that the CODEC has been initialized with the default register settings when the system boots. However, if the system has not been power cycled but just rebooted, this is not necessarily the case, as the CODEC has no external reset pin but derives its reset signal internally from the power level. Furthermore, if the system upon reboot tries to set a register value to one of the default settings (for example as the result of a hw_params() call), then the regcache mechanism will disregard the write as it assumes the default value is already set, which is not necessarily the case. As I see it the solution to this problem is simply not to assume anything about the register settings, so that the first write to a given register always takes effect. I can work on a patch to accomplish this, however, since so much work apparently has been laid down in getting the default values into the driver in the first place, I'm assuming there's something more to the story that I'm missing, so I'd like to get a better grip on this before I dive in. /Ricard -- Ricard Wolf Wanderlöf ricardw(at)axis.com Axis Communications AB, Lund, Sweden www.axis.com Phone +46 46 272 2016 Fax +46 46 13 61 30

[alsa-devel] [PATCH v3] ASoC: MAX9860: new driver
by Peter Rosin 16 May '16

16 May '16

This is a driver for the MAX9860 Mono Audio Voice Codec. https://datasheets.maximintegrated.com/en/ds/MAX9860.pdf This driver does not support sidetone since the DVST register field is backwards with the mute near the maximum level instead of the minimum.

[alsa-devel] ERROR messages when PROBE_DEFER ?
by Ricard Wanderlof 16 May '16

16 May '16

In sound/soc/soc-core.c:snd_bind_dai_link() (and a couple of other places), there are a number of dev_err printouts followed by return -EPROBE_DEFER. Should these really be ERROR messages, as a probe deferral is not an error? Admittedly, if there really is a problem, it's nice to get some information about it, so perhaps the error level should be relaxed somewhat? A case in point would be a SOC machine driver which needs a GPIO which is not loaded until after the kernel has booted. /Ricard -- Ricard Wolf Wanderlöf ricardw(at)axis.com Axis Communications AB, Lund, Sweden www.axis.com Phone +46 46 272 2016 Fax +46 46 13 61 30
