For me, it works OK most of the time. Longer audio files (ogg/mp3) usually
play without issues, and under rarely and not-understood circumstances some
sort of slight audio distortion (like static in a radio) appears, but it's
just a matter of pausing-unpausing xmms to recover.
For shorter audio samples (lots of different types of wave files) that I use
as notification (IM messages and other events I like to be notified) it's
another story: not so rarely the audio is distorted, and the distortion is
not always the same. Some distortions I can name are: pitch, volume,
clipping and truncating. These are always played with sox (sox-12.18.2).
This happens both with emu10k1 and emu10kx1 (from ports), but I found that
with standard emu10k1 it happens less often for the music (which usually is
playing as long as my machine is on).
I can test the driver to hunt this bug as long as instructions on what to do
are given :)
