Comment 32 for bug 200210

Not fixed for me with 2.6.27-2 (Intrepid alpha 5)

Card :
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02)
 Subsystem: Micro-Star International Co., Ltd. Device 7357

00:1b.0 0403: 8086:293e (rev 02)
 Subsystem: 1462:7357

Adding "options snd-hda-intel model=hippo" to /etc/modprobe.d/alsa-base works for me too, but it's just a workaround til the bug is fix.
Otherwise I had to remove and reload snd-hda-intel (after killing pulseaudio and mixer_applet2).

I also saw this in the dmesg after resuming ; I'm not sure that it is linked but it may be :
