Are these function really both using the same sample? If so, whenever
you trigger it from the foo() routine, on the next call to kbd_handler()
it will be turned off again by the stop_sample() call, so it will never
get a chance to play. If you need to overlap looping and triggered
versions of the same sample, it would be better to use the voice_*()
family of functions rather than the play_sample() routine.

If these samples are in fact different, I don't know what the problem
could be, but if you can narrow it down to something smallish that I can
actually compile, I will be very happy to look at it...
