Just a whish for next fsuipc : 
*Maybe the next FSUIPC could intercept the ATC Wav data stream before being mix with other wav file and direct it to second sound card. (Like intercepting variables).   :D  
*Or just new variables/offset of "what ATC Wav File would be played", then play that ATC Wav file(s) to other sound card, or just new variable/offset of the ATC file name "being played" so we can play it seperately with external program (--> decompress the "big" ATC sound file fist of course - read MSFS SDK).  8)  
*Or a patch so ATC Wav is/can be played on second sound card  :lol:  
So we can hear ATC voices on headset like the real thing.  8)  
Forget esound and epic card because not many of us have that (epic) card.  :(  
Thanks
