Hi Giancarla,

I don't believe that moving to another sound library will help. I think Jenn's Idea to use a thread is the only way to have this happen seamlessly. You could also fork() an instance for the audio section.  As he points out make sure you start the thread using the multimedia library before any calls to xforms. The 2 threads can talk to each other though simple variables or sockets or pipes or maybe smoke signals. I have done this with success with the xine library.

Looking into it further i removed support for gorilla audio. It didn't work on a timeout callback either, too jittery.

Thanks, ill look into the timeout method and let you know if that fixes it. If not i will have to switch to a different audio library...

Im adding gorilla audio to my app and have tried using the idle callback

frame to smooth it out?

Idle callbacks are indeed only invoked if there's lots of time.
And there's no callback for "frames" (I guess this is a screen
refresh - the lbrary doesn't even know about them).

Unless you can put the audio handling into a separate thread
(which might be the cleanest solution, just make sure that
you don't do anything graphics-related from within that
thread!) I'd try it with a timeout - they have a much higher
priority.
