Thanks for the help. I may try some of those tips.

I turned off the KDE sound system in the KDE control panel and now sound
works fine, mostly. Except that only one sound source can use the sound
card at a time.

Of course, my finding has been, on every Red Hat/KDE system I've run, is
that artsd (the KDE "sound system") is really slow and laggy. Running
sound apps *without* it, now, and sound actually syncs up with my
on-screen action. Running artsd makes all sound lag a moment or two
behind the screen events associated with the sound. such as, click on
"stop" or "play" in XMMS, or watch a MM Flash movie or play frozen-bubble.
 Without artsd, the sound is crisp and on-track. WIHT artsd, the sound is
behind the visual. That, IMO, is sucky.

So my choices are: Play multiple sound sources but have them be laggy and
sucky or play one sound source at a time? Or are those my only choices?
