I need jack support in mumble. I can write it myself but the interface is not documented at all. If you could tell which classes and methods need to be implemented.
You need to implement a subclass of AudioInput and one of AudioOutput. Have a look at the existing classes for how to do this.
Ok. The source seems clear enough. But what do I do to make it available in config? Sorry, never used Qt before.
Implement the classes and have a static AudioInputRegistrar and they'll turn up by themselves.
