I have a Hisense U6H Google TV and am unable to change the audio output. The only option that isnt greyed out is the standard output. I cannot select ARC. My setup is as follows: TV>ARC-HDMI adapter>External speakers. I'm thinking that the adapter might be the issue. The TV is automatically directing all audio to the ARC connection except from certain apps (mainly Kodi). Anyone have any ideas?
Are files you are playing with Kodi surround sound. Do you have passthrough enabled?
