Hello,
After reading Mr. Stewart's excellent background posts on utilizing
AudioOutputUnits for controlling which outputs are used on a multi-channel
device, I was finally able to route audio where I wanted on two different
multi-channel devices, each with a different buffer arrangement.
The problem now is that I can no longer get audio to come out of the
'built-in audio' device. All calls to CoreAudio/AudioUnit functions seem
to return with no errors, but the callback function is not getting
called. I know this *should* work, as I can get the 'PlayAudioFileLite'
sample code to output to any of my devices (including the built-in audio)
using the Output Audio Unit.
Does anyone have any suggestions as to what would prevent the callback
function from being called, or at least how to determine programmatically
if things are not getting set up properly?
Thanks in advance.
