Hey,
I think I found the culprit. First of all, it seems that AULab expects
the same number of input and output channels. In my case, I need an
8-channel output and thus also need to declare 8 inputs.
AUPannerBase::GetChannelLayoutTags, however, only declares three
possible input tags: mono, stereo, and B-format. Overriding
GetChannelLayoutTags and adding kAudioChannelLayoutTag_AudioUnit_8
seems to do it.
It's still rather annoying that AULab expects the same number of input
and output channels. Is there no way to simulate an 1 --> 8 channel
situation?
