Comment 1 Andrea Chiavazza 2005-01-31 21:36:39 UTC
sound is still broken in the latest testing kernel.
To summarize:

WORKING
kernel-2.6.9-1.681_FC3.i686
kernel-2.6.9-1.724_FC3.i686

NOT WORKING
kernel-2.6.10-1.737_FC3.i686
kernel-2.6.10-1.753_FC3.i686
kernel-2.6.10-1.741_FC3.i686


Comment 2 Andrea Chiavazza 2005-02-07 19:00:39 UTC
Looks like there is a way to fix sound on the kernels marked above 
as "not working" as it´s been reported on the net by someone.
The fix consists in muting "headphone jack sense" "line jack sense" 
mixers setting via any mixer setting programs like "volume 
control", "alsa mixer" and similar.
Theese setting were apparently introduced in 2.6.10 and are meant to 
mute speakers when headphones or line-in jacks are plugged in.
I'm still not convinced that the actual behaviour is normal but I´m 
going to close this bug anyway becouse the sound IS working after 
all. Someone that understand well how theese "jack sense" things are 
supposed to behave will possibly report a new bug on the issue.
