HC Tips and Tricks
The only documented HyperCard feature related to sound that requires System 6.0.7 is the use of multiple sound channels, as in 'set the soundChannel to x'. If you try to use multiple sound channels on 6.0.5, you get no error messages. HyperCard simply plays your sounds sequentially using the single sound channel that's available instead of playing them simultaneously on multiple channels.

System 7.5.3 includes Sound Manager 3.2, which, unlike all previous versions of the Sound Manager, produces system beeps asynchronously. If you have a script that loops, and if it beeps each time through the loop, with earlier versions of the Sound Manager the script would pause while the beep sound was playing. With Sound Manager 3.2, the script does not pause for beeps -- it simply queues up beep after beep at a crazy mad pace until the exit condition of the loop is met. The Sound Manager then plays each of the beeps that were queued up, until either A) you quit HyperCard, B) you hit the restart button, C) you go mad, or D) the queue is exhausted and the beeps stop. They will eventually stop, if you wait long enough. You can alter your scripts so that they beep only every so often within loops, or so that they play some other sound and wait until the sound is done.

Use the control strip to set system volume to 0, then wait for the
beeps to flush out of the queue. The menubar will not flash as the
beeps happen. -- Rodney Tamblyn
Instead of putting your sounds into stacks as resources, try creating an object (a button, e.g.) and setting its script language to AppleScript. Then use the following script: on mouseUp tell application "Finder" open file "MyHD:MySoundFolder:MySound" end tell end mouseUp You must specify the path name, and the file(s) MySound must be system 7 snd files. This works very nicely, even plays 16-bit sound files. Of course, AppleScript stuff must be installed on the target system, etc. This approach also makes it very simple to change the sound files, simply by moving them in or out of the sound folder in the Finder.
