[feature request] force R&L only when playing music to a PLII receiver

I’ve been trying to work out if its possible to solve this problem – http://forum.kodi.tv/showthread.php?tid=296805
Is this possible via a DSP plugin and is there an existing plugin that will do it?

ie. send a multi-channel signal (not stereo) via hdmi which only includes 2 or 2.1 in order to fool the receiver to play pure stereo.
– and if possible do this only when playing music not video (but perhaps this part can be handled by the auto audio switcher plugin).

All because I don’t want to find my receiver remote and push the mode button a few times Smile
