Allow selection of output device #3
Description
Right now the audio output is limited to the default multimedia output device at the time of instantiation of the instantiation of the stream (when a song starts). Handled in MusicManager.PlaySong(...)
It would instead be preferred to use the MMDeviceEnumerator to populate a menu with a checklist of available audio output devices. The default would be selected (by default). Changing it while the song is playing should transfer the ouput to the newly selected device with minimal interruption. Will need to subscribe to events indicating when devices are added, removed, and disabled.
