Hi there is am new to android boxes and kodi but am stuck with pcm input on my Yamaha amp. I have looked through the forums and tried the pass through. I have hdmi to tv then spdif to amp. The TV pumps out full surround when watching terrestrial. Last night I tried hdmi straight to the amp but still just pcm. I have tried xmbc, and other apps but no surround. Any ideas? I tried a 5.1 channel test on Google and had output through front 3 speakers but not rear.
