Phonon control or selection of Left or right channels or both

Hello,

I've just searched this list and the trolltech list on if Phonon allows you to control Left or Right audio channels and there is no mention of this, so before I go building a custom WAV playing device using the example: qmusicplayer .... I humbly ask for a straight answer on said capability. Is is possible, or should I be looking at something new?

BTW:

The blog post by Garet: http://labs.qt.nokia.com/2010/05/10/...-qtmultimedia/ titled:
Low-level audio processing with QtMultimedia
mentions the QAudioFormat::setChannels() ... but is this for generating audio 'data' and not for selecting the physical audio channel of a given audio device?

I am using this in Mac OS, and the 'capabilities' example only returns: "Internal Speakers" for what is call
