[alsa-devel] [PATCH] hda: slave_dig_outs code block in wrong location
by Matthew Ranostay 25 Sep '08

Removed invalid references to slave_dig_outs inside the S/PDIF IN capture switch control. Beforehand this was basically a mute switch for the S/PDIF outs as well.

[alsa-devel] How to find out which PCM handle ASCII identifier to pass to snd_pcm_open?
by Andre Kirchner 25 Sep '08

25 Sep '08

I have just started learning ALSA's api, and came accross some examples at http://equalarea.com/paul/alsa-audio.html, which pass argv[1] to snd_pcm_open. My question is which should be the values of argv[1] for the microphone, and left and right speakers devices? I'm not sure this is the right mailing list for this question, and I apologize if not :-) Thanks, Andre

[alsa-devel] [PATCH 0/4] ASoC updates
by Mark Brown 24 Sep '08

24 Sep '08

This series fixes a couple of bugs (neither of which affect 2.6.27) and introduces a new API call for marking disconnected pins, mostly as a placeholder for future development so machine drivers can start using it now and then benefit when a more substantial implementation follows. The following changes since commit 3090258fed179996ac4daecb482bad28d84cb054: Jean Delvare (1): ALSA: ASoC: Convert tlv320aic3x to a new-style i2c driver (v2) are available in the git repository at: git://opensource.wolfsonmicro.com/linux-2.6-asoc for-tiwai Mark Brown (4): ASoC: Fix inverted input PGA mute bits in WM8903 ASoC: Fix build of GTA01 audio driver ASoC: Allow machine drivers to mark pins as not connected ASoC: Use snd_soc_dapm_nc_pin() in GTA01 audio driver include/sound/soc-dapm.h | 1 + sound/soc/codecs/wm8903.c | 4 ++-- sound/soc/s3c24xx/neo1973_wm8753.c | 17 ++++++++--------- sound/soc/soc-dapm.c | 20 ++++++++++++++++++++ 4 files changed, 31 insertions(+), 11 deletions(-)

[alsa-devel] Something wrong with snd_pcm_avail_update
by Lennart Poettering 24 Sep '08

24 Sep '08

Heya! There seems to be something wrong with snd_pcm_update_avail() for mmap in recent 2.6.26 kernels: Quoting Alexander Gavrilov: <snip> Fedora 9 with kernel 2.6.26.3-29 exhibits a bug where the driver decrements its hw.ptr under certain stress conditions, or at least it appears so from debugging. It causes alsa-lib to give absurdly huge avail numbers to pulseaudio, which crashes it. This patch adds a work-around to avoid such unfriendly behavior until the bug is fixed. As this is not a real fix, it displays a message every time it is activated. </snip> https://bugzilla.redhat.com/show_bug.cgi?id=462200 (see the patch attached to that bug report) Takashi, Jaroslav, do you know anything about this?
