Hi all,
I apologize if there is an obvious answer to this question, but
after half an hour of scrounging around I haven't found anything.
Currently I have a program that uses CoreAudio (OpenAComponent(),
AudioUnitSetProperty(), AudioOutputUnitStart(), etc) to play back a
mono stream of audio. The program works fine, but currently it
outputs the mono audio to both the left and right speaker of my Mac.
What I'd like to be able to is tell it to output the mono audio to
only the left speaker, or only the right speaker.
Use kAudioUnitProperty_AudioChannelLayout + input scope to tell the
audio unit that your source is Left or Right.

What's the best way to do this? Do I need to change my program to
output a stereo stream, and make half of the stereo stream always be
silent? Or is there a more clever/efficient way?
Thanks,
Jeremy
