I don't know if this has been answered before but here's the situation:
I am trying to play H264/AAC 6 channel movies with openelec 4.0 (gotham) beta 3. I get only 2 channels through my chinese HDMI/optical splitter as the TV doesnot support passthrough.
Pi -> HDMI optical splitter -> TV (video) - Yamaha amp optical cable (audio)
This works fine for passthrough formats like AC3 and DTS but not for AAC as I get only 2 channels. I have tried every possible combination. The Yamaha amp is an old model and does not have HDMI inputs. If I set HDMI out at 2.0 channels in xmbc and try to transcode to 5.1, I still get 2 channels. Most probably because 6 channels LPCM is being output from the HDMI and the splitter does not know how to feed that into the optical link or the amp does not support multichannel PCM.
Is there any way I can transcode the AAC 5.1 into AC3 and then give it to the splitter? Maybe do an upmix of stereo? How?
