I also did a quick test with beta 3 on my MiniMXIII II. Audio bluetooth works!
Thank you very much for your effort!
kszaq, with the temp-sensor-disabled builds there does seem to be a bug (maybe not a bug, but different to the normal build) when using the kodi start-up animation, whereby a 'ghost image' of the last frame of the animation is displayed momentarily before the animation starts.
I have not seen this issue with the normal build, is there some cache that is not being cleared in the crippled builds?
nvm: I've now seen it on the normal builds as well. (Maybe more to do with the animation itself)
