Hi

I see the same problem ; as you have the code for this demo, do you see 
what part in the code could cause this ? I think it's related to the 
sound interrupt hreq, which IIRC is not completely emulated in falcon 
mode. It's possible the change I made (which should be valid) are 
exposing some limitation in hreq emulation.
