[alsa-devel] HDA - enable snoop on sch
by Tobin Davis 02 Feb '08

02 Feb '08

This patch enables snoop on Intel SCH chipset, eliminating static during playback. Signed off by Tobin Davis <tdavis(a)dsl-only.net> P.S. I know this is real close to the final release, but it is critically needed for product enabling. The patch has no effect on other components, and has been tested on production desktop and laptop systems, along with Intel's Mobile Internet Device. This is the last patch needed for release.

There is already a --no-upload option, which saves the output to /tmp/alsa-info.txt but doesnt upload it. Is that sufficient ? -- Happiness is like peeing your pants.

[alsa-devel] underruns and strange code in pcm_rate.c (and patch)
by Stas Sergeev 01 Feb '08

01 Feb '08

Hi. I spent 4 week-ends debugging the constant underruns and lock-ups with the libao-based programs. Now I've finally tracked the problem to some strange code in pcm_rate.c, namely snd_pcm_rate_poll_descriptors(). I am not sure what was the reason behind altering the "avail_min" every time. Looks like some heuristic was intended, say "see what amount of fragment part was written now, and make sure that amount of free space will be available next time, after poll". Whatever, this code gives underruns. It can increase avail_min by almost period_size. libao sets avail_min==period_size, so we can end up with avail_min==period_size*2. libao sets buffer_size==stop_threshold==period_size*2. So we end up with avail_min~=stop_threshold, which gives underruns. Since I don't know how this code was indended to work, I just removed it, and everything works perfectly now (also had to patch libao to check the returned rate). The patch is attached, any comments?

It blew me away too.

What they were looking for was output from alsactl. Take a look at what it generates. Use the -f <filename> path to save a temporary file that can be appended to alsa-info.txt.

[alsa-devel] Salsa-lib add snd_pcm_get_params
by Matthieu CASTET 01 Feb '08

01 Feb '08

Hi, in 0.0.14, snd_pcm_get_params is missing. Is is not even in the stub form in pcm_macros.h. Why this function is missing ? As it is quite trivial, could it be added in pcm_macros.h or pcm_params.c. Thanks Matthieu

[alsa-devel] [PATCH/KCONFIG] - Add SUPERH depends to sound/soc/sh/Kconfig
by Kristoffer Ericson 01 Feb '08

Currently you will see an empty "SoC Audio support for SuperH" menu when building for other archs (example pxa).
