No.  I don't use esound, artsd, or any other sound daemon.  Just straight
mpg123 (built without esound).  It mostly works fine, except under heavy
loads (buildworld or huge port builds), or when text is scrolling in
certain apps (interrupt problems?), in which case it either slows down,
breaks up, or both.

So, I think the problem runs a bit deeper than suggested.  Sure, a sound
daemon will impact performance, but the problem exists even without.
