Title: Message
Hello,
I am trying to
programmatically create an aggregate device, and for the most part, it
works. Sometimes, however, the coreaudio API calls succeed, but in the
audio-midi tab, the aggregate device has 0 inputs and 0 outputs. I would
like to be able to detect this, delete the aggregate audio device, and try
again. However, I cannot detect this condition myself. Hallab cannot
detect it either, for it displays the correct (non-zero) number of input
and output channels. When I try to use the
kAudioDevicePropertyStreamConfiguration property and count the number of
channels, I always get the correct number.
So, can anyone tell
me how else I can count the number of available inputs and outputs? The
audio/midi properties tab gets it right, and I would like to be able to do the
same.
Philip Lukidis
