Hi,

Trying to migrate to git master of kernel tree I see that my sound
stopped working.
Initially I though a problem in device configuration/detection in kernel
driver is the issue, but its not. In just that pulseaudio refuses to
work with alsa device.
Since today everything is routed through pulseaudio, even alsa it looks
initially as if sound doesn't work at all.
If I were pulseaudio hater, I would think of that as a feature, but I am
not.


I attach verbose pulseaudio log.
I don't see anything very interesting there.
Kernel seems to reject the access because device is busy, but I know
that it isn't (for example I can unload snd_hda_intel freely, fuser
shows nothing on /dev/snd/* ...)

vanilla 2.6.35 works fine.

100% reproducible.

Since I know you will ask me for alsa-info.sh output I attach it.

(for long time I use power_save=0 parameter on snd_hda_intel.
I can just disable that in kernel config, but I keep it to maybe fix
issues I had with this (mostly pa crashes, which otherwise doesn't crash
at all)

I should probably do a bisection, but I am very short on time lately.

Best regards,
Maxim Levitsky
