Hi,

I've recently purchased this home theatre system and it seems to be working great with everything except for my ZBOX with Openelec/Kodi: lg-LHB755W

The zbox is connected directly via HDMI to the LG system and It seems that no matter what configuration i attempt, only the front left and right speakers are working when playing video content with 5.1 surround however funny enough, the following surround sound test file works if i open this from file manager (only with passthru enabled): http://www.lynnemusic.com/surround/www_l...d_test.ac3

I was previously running 5.0.8 and upgraded this morning with no change, the following are various configurations and tests. I've disabled the onboard analog audio in hope that would help but has made no change. I've been searching these and other forums, testing various configurations for hours and am hitting a brick wall.

The one thing that stands out is that ALSA is detecting only 2 channels from the LG system.
