this is dmix.  dmix is hosed for a lot of people currently.  On my
laptop, it can do any of the following after a short time (say, 5 min)
of music playing:

a) scramble the sound completely (similar to what you just said)
b) stop playing, use no CPU
c) stop playing, use 100% CPU

Other people I've polled on this using FC3 and FC4 test releases have
had the same issues - though not necessarily all three.

I've discussed this with some people directly on IRC.  I've discussed
this with some people at GUADEC as well, but I can't figure out if FC4
is going to ship with dmix turned on by default.  I don't really know
for sure either who is "responsible" at redhat for this part of the
stack - though I have some likely suspects I maybe should target :)

Anyway, here is a strong warning against it - it is just not ready yet
for a lot of drivers.  Stuff needs to be fixed first, and clueful people
need to look at the problem.
