Same as for FireTV4K. Try to set the PT device to RAW (it's the below sound device), then play a DTS-HD-MA file. Verify what your AVR says and post the kodi.log, please.

Here is a DTS Master HD sample playing. The receiver had no sound and it never even switched to DTS. Was on Dolby Digital+ the entire time.

Let me ask you this is it possible to play these HD audio files in PCM out of Kodi with fire TV cube. I tried to set the channels yesterday to 7.1
And fixed and turn off passthrough. My receiver showed Multichannel and I had sound playing a true HD file but there was a thumping sound in the sound track so something wasn't correct. I also noticed if I leave it set to 7.1 fixed and stop Kodi and then restart it it starts doing it immediately even though I'm not playing an audio file. Very weird.

Here is the proper link.
