AudioQueue does not output any sound

Question

I have trouble getting sound output on my iPhone experiment and I\'m out of ideas.

Here is my callback to fill the Audio Queue buffer

void AudioOutpu         


        

Answer 1

I usually use 3 buffers. You need at least 2 because as one gets played, the other one is filled by your code. If you have only one, there's not enough time to fill the same buffer and re-enqueue it and have playback be seamless. So it probably just stops your queue because it ran out of buffers.
