Hi
I have created a custom sAPO (based on the SwapAPO example) that handles
multichannel audio input but outputs only stereo audio. I have tried using the
IAudioProcessingObject::IsInputFormatSupportted. I return back to the calling
routine the requestedInputFormat as the supporttedInputFormat along with a
HRESULTS value of S_OK. But the system still rejects the values ( it tries for
about 8 times before finally giving up). I am not sure what else I need to set
up or send to make this work.
