I would like to play a sound asyncronously.  I have Inside Mac V in my lap
and have written the following code using TC 4.0.  Two things are wrong.
First, control is not returned to the program immediately (i.e. not played
asynchronously).  Second, the SndDisposeChannel call causes a bomb.
Here's the code:

#include <SoundMgr.h>

void CSoundPane::DoClick(Point hitPt, short modifierKeys, long when)

{
	Handle	theSound;
	SndChannelPtr	chan;
	
	theSound = GetResource('snd ', 2214);
	chan = NULL;
	SndNewChannel(&chan, sampledSynth, initSRate22k, NULL);
	SndPlay(chan, theSound, TRUE);

	/* Drawing stuff */

	SndDisposeChannel(chan, FALSE);
	ReleaseResource(theSound);
}

Thanks in advance,
