[sorry for the late interrupt - I'm just back from a vacation]

Could you postpone reverting for a while?
I guess this possible regression is limited only to a certain type of
ac97 codec chip.  The patch applied there was a fix for many codec
chips.

Which codec chip are you using specifically?  Please check
/proc/asound/card0/codec97#0/* file(s).
Also, run "alsactl -f somefile store" and attach the generated file to
see whether any mixer status inconsistency exists.


Thanks,

Takashi
