There are two Kernel sound driver systems OSS is the old one and ALSA is 
the new one.  So if you have the 2.6.x Kernel, you are probably using 
ALSA.  You do have an issue however, that is how do you have an app use 
the sound driver directly without going through aRts.

In the Control Center, go to:

	Sound & Multimedia -> Sound System

On the "General" tab at the bottom of the page you should find a check 
box: "Auto-suspend if idle after".  Check this box and set it to "1 
seconds" [sic].  NOTE: there is a bug in this so DO NOT set it to "0 
seconds" as this is the same as not checking the box.

Now as long as you don't try to use an app with aRts and an app direct 
at the same time, things should work.

Yes, the output of aRts probably goes through ALSA.

If you set the above in the CC, it should work.
