Lux is using Java, so:
lsof | grep java

If you had kernel 2.6.33, you could just look at the owner_pid field in
in /proc/asound/card0/pcm0p/sub0/status.


If you tell all programs (including mpd) to use the ALSA device "default"
instead of hw:something, sharing should work.
(I don't know how to configure the sound output of the Java VM.)

If you only have one sound hardware device you do not need to do any
manipulation. The problem primarily arises if you have a USB sound
device (which includes a webcam with built in microphone) and that
is plugged in at boot time, and that becomes the first sound device
for some reason.

Are you frightened of breaking something?

Yes that is fine.

So you are running XFCE (whatever happened to Windowmaker) and are
running the XFCE sound mixing system.

Out of your sound card in particular? Which one do you have btw?

That is a bit strange, but with what are you playing the music?

It may be using the OSS devices depending on what interface it
is configure/programmed to use.

When you run mpd, does it always or ever show as using the /dev/snd/pcmC*
devices?
