Thanks,
Ive worked around this myself, by writing my own non blocking sound driver.
It works like this:
One function Play_Sound (UInt8 num beeps) which sets up some static data
Then a Do_Sound function which is called every 100ms on nilEvents, which
processes the static data.
Hence I can queue up 3 beeps, then on the first do_sound I can beep, on the
second do nothing, third beep etc,
creating a beep - 100ms gap - beep.
This can be expanded to be more complex, but its fine for me.
The only real problem comes if you want to call Do_Sound at a higher speed
as if another message is being processed you get delayed, also you can get
the odd nilEvent for no apparent reason, but it seems to work fine so far.
