Here's an update:
As Phonon allows one AudioPath to be used for several MediaProducers the 
channel selection in AudioPath is ambiguous. Also technically the information 
about the available channels comes from the media data. (If you were to look 
for the channel selection, which class would you look at first?)

I'm thinking of the following now:
class AbstractMediaProducer {
	AudioChannels availableAudioChannels();
	selectAudioChannel( AudioChannel, AudioPath* = 0 );
	VideoChannels availableVideoChannels();
	selectVideoChannel( VideoChannel, VideoPath* = 0 );
