Re: what would cause QTSetComponentProperty to fail with a kAudioUnitErr_InvalidPropertyValue err?



Can you explain a bit more about what you mean? If you plug-in is currently not exposing any AudioDevices, then the Sequence Grabber won't see anything. If you plug-in is exposing an AudioDevice without any AudioStreams, then I imagine that most apps would ignore your device.

If it's something else, you'll need to get into more detail about what you are doing and what you expect to see happen.

My audio plug-in should be selectable without having live audio streams (or a device connected) though, right?
