I would use vchans to multiplex the sound card.

Eg sysctl hw.snd.pcm0.vchans=4

Then tell artsd to use /dev/dsp0.3 and your other programs will use /dev/dsp0
(which is linked to dsp0.0).

If you have other 'long standing' sound apps (eg an mp3 player) you should tell
them to use dsp0.2 etc..

(BTW 4 is just an arbitary number I pulled out of my hat)
