I have written some sound playing program which uses the new sound manager.
However there seem to be some major differences between the mac ][ version, and
the plus version. For instance, when playing snd format one resources
I open a new channel with SndNewChannel - passing all the resource initialization variables, then call SndPlay (which works). However to dispose of the channel
I call SndDisposeChannel - here is the problem. On a mac ][ this is ok - works with no problems, on a plus - it bombs (deleting SndDisposeChannel stops the bomb). Does anyone know if SndPlay destroys the channel itself? (which would be a 
prblem when playing async - like I am). The code looks something like:

	SndChannelPtr	*chan;

	SndNewChannnel(&chan , ....);
	SndPlay(chan, TRUE); 		/* play asycronously */
	while (stillplaying...) loop
	/* when finished */
	SndDisposeChannel(chan, FALSE);		/* works on ][/ bombs on + */


Any comments or suggestions would be great. 
	Thanks,
