You can disable it in KDE's control centre/Sound and Multimedia/Sound system. 
Just uncheck the "Enable the sound system" box, then apply.

Most soundcards are not capable of multiple audio streams, and the aRts sound 
server is a prime candidate for causing problems, as it grabs the soundcard, 
then other sound apps won't work.

The last thing you want is having multiple problems preventing the sound from 
working.

You might also check.
cat /proc/asound/cards   to see if the card is actually showing up as card0.
