It would be useful to have a manual test or an example that allows creating and deleting multiple audio sources and sinks for any available audio device.

An idea would be for example a qml application that has two columns, one for sources and one for sinks. The user can add sources and sinks for any available device and remove them whenever. The source operation can be verified with a simple visual showing signal strength for each source. For sinks the user would be able to play a sound to a specific sink.
