Hi Tuviah.
I don't find any complete documentation for Hardware Plugin. Only the core audio mail list help me to understand the process.
Are you suggesting that SampleHardwarePlugin will mirror the output sent
to it as an output device when acting as an input device?
Something like this. If you set your Hardware Plugin as the general audio output in Audio/Midi Setup, your instance in each app will be able to hold the stream.
I use PortAudio in my Hardware Plugin to reflect this stream into an other device.
But maybe i'm wrong.

Hi Alex,
Is there any documentation you can find for the HPBase classes and/or core audio cfplugin drivers in general?
Are you suggesting that SampleHardwarePlugin will mirror the output sent to it as an output device when acting as an input device?

I'm currently working on SampleHardwarePlugin too.
I'm not sure but to get the strems from application who instantiate your plugin you need to set your device as a output device (or input) of your application. You can also set it as your system output/input.
Just don't forget to overload the CanBeDefaultDevice() in SHP_Plugin class and returning true.
I'm looking at SampleHardwarePlugin as an example of how to write a user mode audio driver. It displays as a device in all the applications I need to target for my virtual audio device, but doesn't actually deliver any streams? Would anyone on this list have any sample code or projects they can point me to which are more complete?
best,
Tuviah
