Hi!

Intel desktop machine:

00:1b.0 Audio device: Intel Corporation NM10/ICH7 Family High
Definition Audio Controller (rev 01)

Sound worked ok in both in previous kernel versions.

Any ideas?

Thanks,
									Pavel

How broken?  Did you get any error messages?

If the behavior depends on the application (e.g. ALSA vs OSS), I'd
suspect rather a device permission problem at first.  There are no
significant changes between 3.19 and 4.0-rc3 regarding HD-audio.

I get some funny, faint, rhytmic noises where audio should
be... Actually, I somehow suspect something is wrong with time during
video playback.

My system contains pulseaudio, so it is more complex than ALSA vs OSS
:-(.

Audio seems to work ok on thinkpad x60 with very very similar config.

Did you try audio playback without video on chromium?

OK, that was missing information :)
Then there should be any difference in the kernel driver side -- it's
only a single PA process who accesses the sound device in the very
same manner no matter what clients are used (after all it's the
purpose of PA).

OK, then another thing I would check is to try different sample rates
(e.g. via playing WAV files over PA).

Yes. Does not work, either; I tried
http://www.thenakedscientists.com/HTML/podcasts/ .

Like this?

pavel@amd:/usr/share$ pacat ./sounds/alsa/Front_Right.wav
pavel@amd:/usr/share$ pacat --rate=48000 ./sounds/alsa/Front_Right.wav
pavel@amd:/usr/share$ pacat --rate=44100 ./sounds/alsa/Front_Right.wav
pavel@amd:/usr/share$ pacat --rate=32000 ./sounds/alsa/Front_Right.wav
pavel@amd:/usr/share$ pacat --rate=16000 ./sounds/alsa/Front_Right.wav
pavel@amd:/usr/share$ pacat --rate=8000 ./sounds/alsa/Front_Right.wav

This seems to have behaved as expected.

Thanks,

Hmm.  You might see a difference when comparing
/proc/asound/card*/pcm0p/sub0/* files between working and broken
cases (while playing something).

Other than that, I have no idea.  A bisection would be needed, I'm
afraid.

:-(.

To make it more fun, it now appeared on x60... it looks like it has
something to do with starting browser early after boot.

Restarting the browser seems to fix it.
