[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.
