I had a related (?) problem with my ThinkPad R52.
00:1e.2 Multimedia audio controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller (rev 03)
Sound seems to be played from apps POV, but no noise out of headphone / speakers.
The "KMix solution" worked - no further changes on module params etc needed.
Just uncheck (!) "Headphone Jack" AND "Line Jack Sense" under "Switches" Tab in KMixer.
Maybe this helps someone - are there equivalent options for Gnome?
