I'm having a hard time getting sound to pass through the matrix mixer.
I'm basing what I'm doing on the MatrixMixerTest example app and
everything seems to be wired up OK - I'm definitely getting my synths
pulled on, but no sound.
There seems to be a variety of different places where levels need to
be set and I'm setting them all I think. Here's what I've got:
set the input level for each channel on each input bus:
kMatrixMixerParam_Volume, kAudioUnitScope_Input
enable each input bus
kMatrixMixerParam_Enable, kAudioUnitScope_Input
set the level of each intersection within the matrix
kMatrixMixerParam_Volume, kAudioUnitScope_Global
Some more explication on addressing these intersections would be
good.
set the level of each output channel on each output bus
kMatrixMixerParam_Volume, kAudioUnitScope_Output
set the global level of the mixer
kMatrixMixerParam_Volume, kAudioUnitScope_Global, 0xFFFFFFFF
Enable each output bus
kMatrixMixerParam_Enable, kAudioUnitScope_Output
That all looks OK. Buses are enabled by default so you shouldn't have
to specifically enable them.
how about silent bits? sending any in? getting any out?
