Apple tv app has no sound when streaming on Android TV to Soundbar using HDMI CEC
I have had this issue on the Android TV (android version 11) where some Movie titles will play without sound from the Apple TV app. I have found a solution that works for me but if this is a problem Apple can fix with an update it would be appreciated. The HDMI CEC needs to be refreshed when Apple TV app starts.
This audio issue seems to be for HDMI CEC via ARC to Soundbar using HDMI lead (4K-8K compatible HDMI Cable)
Most Movie Titles in Apple TV app do play fine but I have encountered a few titles that do not. I have noticed other viewers have similar issue that pinpoints to an Apple problem or a particular Movie title problem.
The following Movie titles never play first go with Audio in the same scenario every other Movie is played in. I have read in the discussions here some people claimed refunds on the Movie titles. I do not want to claim a refund but would seek to see the problem resolved. I have included steps taken to reproduce this problem and apply a solution that works for me.
- Edge of Tomorrow (Dolby Vision) no sound, app shuts down, TV restarts or a combination of these events with no sound.
Steps taken to resolve loss of Audio in Movie Now Playing in Apple TV app
- Turned HDMI CEC OFF, Movie has sound via the TV Speakers.
- Turned CEC back on during Movie playback, Audio works I now have sound in that Movie via the Soundbar.
Stopped playback moved on to The Fifth Element (HD) to see if Audio now works.
- The Fifth Element (HD) no sound
- Turned HDMI CEC OFF, Movie has sound via the TV Speakers.
- Turned CEC back on during Movie playback, Audio works I now have sound in that Movie via the Soundbar.
TV is a 2021 TCL 65C727 it is compatible with HDR10+, Dolby Vision, Dolby Atmos among other things
I can play any Apple Movie using the PlayStation 4 Pro on this TV in HDR, Dolby Vision, Dolby Atmos etc with no Audio problem. I can play anything on the TCL outside of the Apple TV app no Audio Problem.
Issue is with the Apple TV app on this device
TV Software is up to date, Apple TV app is current.
Final Test, restarted TV to then watch both these Movie titles again to check for Audio issue they both played with TV Audio but not with HDMI CEC Audio.
Steps taken to resolve loss of Audio in Movie Now Playing in Apple TV app AGAIN.
- Turned HDMI CEC back on during Movie playback, Audio works I now have sound in that Movie via the Soundbar.
Just in case, one last test after turning HDMI CEC back on
restarted TV to then watch these Movie titles again only TV Audio would play sound. I disabled the HDMI CEC again and I then turned HDMI CEC back on during Movie playback, Audio works I now have sound in that Movie via the Soundbar.
sorry for all the BOLD face type it was better than a SAD FACE I hope this can help someone else get some better sound without thinking they need to disable Dolby Sound.
It is my opinion Apple could do an update to have permission to restart HDMI-CEC when their app opens on the Android TV.
