Hi All,
It looks like 'kAudioDevicePropertPlayThru' is not available, since play through
does not seem to be available through the SoundManager Carbon API or CoreAudio.
(Thanks for the info on this) In the meantime, I thought I would try to get
software playthrough working (has anybody tried this)?
To get software playthrough , I assume I would need an AudioDevice that supports
both input and output channels. On my system I get 2 audio devices, both called
"Built-in audio controller". One AudioDevice supports input channels and the
other supports output channels, but neither supports both.
My understanding is that to use software playthrough, I would need to use a
device that had both input and output channels and then copy the data from the
input to the output buffers in the IOProc. I'm not really sure if the problem
I'm having is just the system/OS configuration I have or if other people are
seeing this as well. Are other people getting 2 devices like this?
I am running on a Blue and White G3 (Yosemite) with OS 10.0.4.
Any info, guidance or corrections to my assumptions is greatly appreciated.
Thank you,
