Does your au pass the auvalidation process and correctly report these
channel capabilities?
% auval -v ...
There's a readme for auval in /Developer/Examples/CoreAudio

Hi,
Still struggling with this, sorry - I know it's been covered
before, and I have tried the archived and docs. It doesn't help
that I'm also new to C++.
After trawling the archives I've come up with the following to
publish config info about my AU:
UInt32 AUStub::SupportedNumChannels ( const AUChannelInfo** outInfo )
{
static AUChannelInfo config[] = { {1, 1}, {1, 2}, {2, 2} };
if (outInfo != NULL)
{
*outInfo = config;
}
// return number of configs
return 3;
}
This is getting called OK, but the AU still isn't showing up as a
mono->stereo component in AULab. I know I need to override
AUEffectBase::ProcessBufferLists() as well to get anything to
actually work, but shouldn't the AU at least show up in the list
without this (even if it fails to function correctly)?
What else do I need to do just to get my AU to show up as a mono-
>stereo component?
Any help appreciated. I was getting along fine but this issue has
really bogged me down.
