This is annoying!
I can't get the 5.1 sound working propperly under Linux.
The first release of the nVidia "official" drivers (nvaudio) used to support only stereo.
So I installed ALSA.
It works... but the problem is that the center channel jumps from time to time to another speaker. It seems pretty aleatory, although it has a "preference" for the rear left speaker. Unmuting/Muting the channels and "playing" with the alsamixer magically solves the problem... for a couple of minutes
Yesterday I decided to give the new nVidia drivers a try.
Now, the 5.1 sound does work, but with the same problem as regards the center channel. It jumps arround all the time!!!
Besides, nVidia doesn't provide us with any mixer to "fix" the problem.
Can anyone tell me how to avoid this?
Is there a workarround for this?
I have this problem playing DVDs, both with Xine and MPlayer.
Thanks for your help!
