Tests with Amlogic's player:
DD+ 7.1 -> DD+ 7.1
Tests with Kodi:
TrueHD 7.1 -> MCH PCM 7.1*
Atmos 7.1 -> MCH PCM 7.1*

This is interesting. I have been told by Minix/Amlogic that the SoC doesn't support more than 6 channel PCM (only 3 stereo I2S channels) and they cannot enable multichannel LPCM due to Dolby licensing restrictions. Even on OpenELEC it doesn't do anything more than 2.0 PCM.

Since you are getting 8 channel LPCM from Dolby TrueHD tracks, if you install Kodi 16 beta, you should get the same from DTS-HD Master Audio 7.1 tracks also.
