Both should work. The more modern form is
	-vm sound=OSS -vm display=X11

I had to get a *very* fresh version of the ALSA kernel drivers (as in "from 
CVS") (and rebuild the kernel, of course) to get my motherboard's mixer to 
set up the microphone input right (I have an Intel D865PERLX motherboard).

But I assume that you've got your system working so that both the KDE apps and 
the OSS apps (like sox/play/rec) work.

Have you made sure that the OSS emulation modules are loaded?

I think ideally someone would write a Squeak ALSA sound plugin.

I'm running a Debian unstable/testing system:

kde 3.1.2 
alsa 1.0.3-1
arts 1.2.1-1

I tell artsd to use ALSA, and to release the sound hardware after 10 seconds. 
In the KDE control panel, this would be "Auto-suspend if idle after 10 
seconds".

I run Squeak using the aoss wrapper:

$ cat ~/bin/squeak
#!/bin/sh
aoss /usr/local/bin/squeak -vm display=X11 -vm sound=OSS -nomixer -xshm 
-display :0 -swapbtn "$@" &

For me, sound output works either with or without the aoss wrapper, though.

I do have a Swiki running, and I make sure that it doesn't hog the sound:

/usr/local/bin/squeak -vm-sound-null -vm-display-null squeak.image &
