We have a patch in F-12 for the Intel HDA audio but nothing for intel8x0. You can work around this by adding 'powersave=0' to the module options. I guess if this isn't fixed we can change the default back to 0.

Comment 5 Eric Moret 2009-09-29 05:39:01 UTC
I put the following in /etc/rc.local which solved the problem

$ echo 0 > /sys/module/snd_ac97_codec/parameters/power_save

Let me know if I should try something else

No workaround for AC97 seems to be available. Set the default to 0 in kernel-
