In the meantime, what you need to do is to manipulate the callbacks from the render thread - the AUGraph has a add/remove notify call and you can do this from there. There's an example implementation of this in the code we provide for OpenAL (openal.org) which uses a lock free message queue to do this.

One other thing you could do with the matrix mixer is to just connect everything up and then use the MM's enable/disable parameter - this has the effect of the MMixer NOT calling that input if the input is disabled (and also when you disable an input it will fade out that input to avoid glitches).

Thanks very much Bill! I opted to try the latter, and it works beautifully.

Chris
