What were you trying to do?
Play sound in Matlab using the following commands from within Matlab:
>> load handel
>> soundsc(y)
What's wrong:
On Linux, only a loud, screeching sound is produced; on a Sun, it
plays.
I verified that sound will play correctly on the machine in question (xmms
plays mp3's properly).
Interestingly, when this is run on a Linux machine and displayed on a Sun, the
sound plays OK. I contacted the Mathworks and they supplied this less than
satisfying reply-

I'm not convinced that this gets us off the hook on possible Linux sound
misconfiguration. Could someone please take a look at it? Please cc any reply
to asanka who reported the problem to me.
What should have happened:
Should have heard Handel.
