Yes, I've noticed this, however it seems to happen only on MOD files in 
XMMS, and low bitrate 32 or 22khz sample rate mp3's. I've yet to notice 
it on high bitrate mp3's and ogg, MOD's often have harsher stereo 
seperation and would make it more noticable. However I always used to 
notice when the OSS driver was flipping channels on any song, and when 
someone made a crappy CD rip... The mikmod plugin is mixing at 44.1khz 
so you'd think it wouldn't be any different once it hits the driver than 
a 44.1 mp3...

I've never noticied it in anything but XMMS but then I end up listening 
to very little stereo in Xine. I've used little else since switching to 
the ALSA driver. Haven't fired up any games in a while either... One 
interesting  note is trying to play UO on Wine on the old OSS drivers 
would always lock my machine solid on the OSS drivers as soon as Wine's 
directsound subsystem fired up. Cute trick...

I still need pull the latest CVS and see if the latest patches broke 
anything on my card. (Vortex2)
