Hi all,
I have an Asus M6R laptop (http://www.fi.muni.cz/~kas/m6r/) with ATI IXP
integrated sound card. Under 2.6.8.1 I was able to use the sound card
after software suspend (just had to restore mixer settings using alsactl).
With 2.6.9 the sound card does not work after suspend/restore: No output no
matter how I change mixer settings, and the playback is not timed properly
(e.g. when mplayer tries to synchronize audio and video stream, the video
goes too fast using all CPU time and no output to speakers/phones.
I will do a binary search over 2.6.9-pre patches, but I want to ask
whether this problem looks familiar to anybody.
Thanks,
-Yenya

Are there any changes in the sound module?

Yes, the difference is between 2.6.9-rc1 (works) and -rc2 (does not
work). Removing the snd-atiixp module after resume and inserting it
back again helps, but this means killing every app which uses audio
interface (so you cannot keep mplayer running over suspend/resume cycle,
and gnome-settings-daemon keeps /dev/mixer opened all the time too).
I have tried to add printk() to
linux/sound/pci/atiixp.c:snd_atiixp_suspend() and _resume(), but I cannot
see it in dmesg(8) output after resume. Maybe those functions are not
called at all in 2.6.9-rc2 and newer.

Is there any difference between -rc1 and -rc2 snd-atiixp?
