So, I was enjoying the surprising update to Oreo. Everything seemed to be working fine. Then I tried Google Play Movies. The movies play, I can hear sound effects, the score, but no dialogue (voices). I tried the cache and program data clearing, which did not work. I factory reset the Mibox twice (trying after each reset), and it still doesn't work.
Does anyone have any ideas?
If settings sound options don't fix it, try Vudu (my favorite) or Movies Anywhere. Both will show your Google Movies.
