Sounds more like buggy code/libraries/etc. than buggy sound card, imho. I've got an SB Live! Player 5.1 and I
can't say I've noticed anything sounding bad b/c it's played at 44.1khz. Perhaps I should test it vs a good
software upsampler. Still, we're talking lossily compressed audio here, at low bit rates. Most of the damage
done to the sound would happen at compression, not while playing back.

Wouldn't it just suffice to rip and play at 44.1khz? If it's the soundcard, surely it should be noticable
then as well.
