	I have been writing a program in Turbo Pascal, and wanted very much
to incorporate Digitized Sound in it. I bought the Audio Digitizer from
MacNifty (Impulse), and also got their programmer's stuff. It said that you
could use it in your programs to play digitized (SoundCap) files.
	This is true, but I have two problems. The first, and most annoying
problem that I have encountered is that the source code does not do a "back
door" trick on the Sound Manager to elliminate the annoying click that is
produced with every call to StartSound. Apple Computer's Tech Note 19
describes a way to get around this, but I have not been able to get it to
work. I have also been having many troubles keeping StartSound calls from
giving me System Errors (especially ID=02 [Address Error]). 
	Does anybody have a piece of source code floating around that does
this successfully? Or, maybe just some helpful suggestions or comments.

Thanks,

Rob Johnston
