Description of problem: I discovered a very strange bug where there a two sockets used for sound. For instance, I have a couple of loudspeakers connected to the rear socket and they work fine, the sound is perfect. If I plug the headphones (for instance) into the front socket, the rear sound gets off (as it has to), but the sound from the headphones is really bad. But if I unplug it a little (as if only one channel is used) the sound is fine again (even if not perfect). When completely plugged-in, the sound is again quite good only if I unbalance a little right and left, or better if one is off (using the master settings). It seems to be still a stereo sound (not sure, by the way), and well balanced Version-Release number of selected component (if applicable): alsa-lib-1.0.12-2.fc6 alsa-utils-1.0.12-3.fc6 How reproducible: Always I have two different PCs, with different sound cards, different loud speakers, different headphones and the effect is the same. Steps to Reproduce: 1. Use fron and rear sockets at the same time 2. Balance and unbalance the master settings 3. Actual results: Bad sound from front socket Expected results: Additional info: I am not sure, but this seems to occurs only recently (say 15-20 days). I update the system every day.
okay, could you please check the latest drivers / packages? (ALSA 1.0.14rc1) How-to is here: http://people.redhat.com/stransky/alsa/
Variation but possibly related If I run the sound detection or play sound and push the headphone or speaker socket ALMOST home the sound works fine out of the front or the back sockets . If I push the plug completely home so it clicks the sound stops. It is as if clicking it in makes the hardware detect it which sends some signal that confuses alsa ( box dual boots to XP which works fine ...! ) This is a white box with all Intel chip sets - the sound card is detected as 82801G ICH7 Family High Definition Audio Controller
Did the driver upgrade as per "Comment 1" and it now works
great, thanks.
