Well, one thing for sure, you're trashing the channel before the sound ever
has a chance...

You need to delay the last line until the sound is done...

Either create a sound channel at startup for use throughout the program, or
register the channel and its start time somewhere and periodically check:

 time has elapsed from start time so the sound has started AND
 that the channel is not busy
