Apple

Hello,

I've been thinking if there's a way to control my speakers input source with the apple TV remote. I currently have a set od Edifier R2000DB speakers and they are decent enough but their remote is quite shite. Ive managed to teach the remote volume control but is it possible to teach it signals for sound source selection? Or to cycle through optical and RCA inputs (I have my tv and turntable conncted to those speakers and I'd love to be able to switch between the optical and Line1 sources).

Any help would be appreciated!
