I tried hooking up the android box to my other receiver just to 100% rule out my pioneer receiver wasn't somehow preventing the surround on the android box. It's definitely the android box that is the root of the problem.
When I watch a movie in kodi with the working android box you can check the "audio stream" and it says 5.1 or 7.1 channel"
When I check with the android box that isn't working it says "2 channel (default)".
Somehow this android box is stuck in 2 channel audio mode
There are even kodi specific settings for the audio. I changed them to allow 5.1 but it didn't make a difference.
I couldn't get this box to communicate with my Sony receiver so I was forced to hook it up directly to the tv. Don't know if that's a related issue or something all together different.
