My current setup:
Motherboard: Asus A7N266-VM (Nforce chipset)
Distro: Slackware 8.1 (tried on RH 8.0 as well, same results)

Self compiled alsa-0.9.0rc7
xine-lib-1.0.0beta6
xine-ui-0.9.18 or my own gui flxine

I have tried several differnt xine-lib versions, from cvs to any of the
1.0 releases, all with the exact same results.

Current mixer setting:
http://www.newtsplace.com/~newt/amixer.txt

I have the mixer setup for all analog outputs, with the Line-in as the
rears, and the Mic as the Center/Lfe outputs.

The problem:
This problem is really perplexing me, in xine, when playing any 5.1
encoded stream the 5.1 channel output 'walks' meaning that the channel
locations are not constant. Sometimes the sound is comming out correctly
from all channels, other times after skipping to another point in the
stream, for example, the channels will be misaligned, the center/lfe
output may be coming out the rear, the rears out the center/lfe, sometimes
the center appears to be downmixed through the front. The only way to get
the channels proper again is to keep skipping through the stream (keeps
re-initializing audio output) until things line up again. I don't think
this is a xine problem, as it happens with both the oss, and alsa drivers,
and I get NONE of these errors with my SBLive! 5.1, using the alsa
drivers, or the emu10k1 driver set.

I have also tested with the exact same result using a test 6 channel ac3
file, with ac3_extract on a vob piped to ac3dec. The channel choice seems
random, at best... :(

Help!

Any ideas!?!
