VLC have the option to choose the output (44k1 vs. 48k) but I couldn't hear 
any difference.

Well I have this with both AOpen AX59Pro (VIA MVP3) and EPoX 8KTA+ (VIA 
KT133A) and with both SB and EPoX's on board soundchip. And moreover I get it 
not only with BSD but with Windows as well (eg. Deus Ex in the scenes with 
speach). So I'm not entirely convinced it's a driver-issue.

But if it were, is SB Live (EMU101) better supported with pcm than the 
cheaper SB PCI XX?

You got aRts working with xmms??? Please mail me a binary!! I haven't been 
able to get it working here!
