Hi

thanks for the example code you sent me ; meanwhile I looked more 
closely and the problem is is fact similar to the fix I made for STE in 
commit 	f9f1a01cea427bd77b7dc47d9dc5a0849f7a0ec4 from 11/1/2020 : the 
int signal must be set to low when play stops, but it must also be set 
to high when play starts (which is not the case actually).

If not then the "active edge register" will not see the transition 
between play/stop and the interrupt will not trigger (previous falcon 
code bypassed the AER and always triggered an interrupt when play 
stopped, which is not the correct way to emulate the HW for this in the MFP)

I will send a patch for this soon to fix the issue.
