your statement of facts, above, is correct. However, there's an easy work
around. If you read the snd into a array, then you can alter its volume
etc by manipulating the values. The following is copied from HELP SND:
you can use ResEdit to copy snd
resources (e.g. from the System file) into individual files (one file
per snd), which you can access with MATLAB's READSND and WRITESND
commands. You can get ResEdit from Apple's web site:

US/Macintosh/Utilities/ResEdit_2.1.3.sea.hqx>
Does that do the trick for you?
