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.
