Hey guys,
I'm working on my App, which is pushing Audio out in multiple channels. Got that working with my old 2 Channel Interface and for testing purposes I always used the default output unit setting for the HAL unit, and configured in Audio/MIDI Setup the default to my interface.
Today I got a Focusrite Interface with 20 Output Channels, configured the Interface to be in DAW Mode (for people familiar with MixControl)
So, I tested my program and saw the output node is only accepting 2 channels when I print out the graph.
The Focusrite is set in Audio/MIDI setup to be the default output device so it should be 20?
If I print out my Streamformat for Input I get 18 channelsPerFrame (which is correct). But the output Node only wants 2 channelsPerFrame.
Any tips? Next thing would be to move away from default output unit and specify which output should be used. Are there any restrictions to kAudioUnitSubType_DefaultOutput?
Thanks
Benjamin
