please note that here multi-channels doesn't mean the multiple
playbacks at the same time, but a pcm stream accepts channels more
than 2.
for example, you can play a wav file with 4 or 6 channels via aplay,
or playing ac3 via ac3dec with -4 or -6 option.
anyhow, it's nonsense unless you have rear and center/lfe jacks...

this problem should be on ac97 chip.
possibly there are some filters active on it.
is 3d sound switch enabled?  well, then it should affect also pcm..
hmm... or maybe a hardware problem?
do you have another soundcard to test?
