Hi All, Happy New Year to you all. Recently a question was posed about playing sounds in FB^3. As it turns out I was in the middle of converting the old FBII Sound Tutor Code myself. Most of the routines were easily done but I'm having a problem with the sound loop call back routine. I can play the sound but when the call back Proc is called it freezes my computer. I've determined that the call back Proc is never reached. I suspect the call back address is incorrect but can't seem to find the solution. Yes I've changed the <LINE> statement to <PROC> and I've exhausted every possible solution I can think of. Has anyone converted this code to FB^3 or does anybody know how to go about this.
