Thanks for the tips, I tried telling aRts to use NAS. I didn't know what
you mean by control center, so I went through the menu KDE --> Sound -->
Sound System and there I marked Enable the sound system, and Enable
network sound.

Now aRts seems to run fine, and Amarok plays music. The problem is that
if I run my QT program (that uses NAS), while Amarok is playing, then I
hear no sound until I close Amarok. Only when Amarok closes I hear the
sound that was probably queued while Amarok was playing. This is already
fine for me on a practical level, although not a perfect soultion in
general.

Regarding alsa dmix, I don't know the technology, but can it solve the
principle problem of two programs using different sound servers? As I
understand it, the programs are using sound server API's and not ALSA
API's so if two sound server's can't coexist right, no fix in ALSA level
can help.
