Mute button and volume on Apple TV not working
I have tried two remotes and the mute/volume buttons don't do anything. I've also tried setting up the custom in volume control, any ideas?
Apple TV 4K, tvOS 15
Question marked as
The remote controls the volume on the TV or audio system directly – not through the Apple TV box*. The remote uses IR for this (unlike bluetooth for the navigation command), so there should be a line-of-sight to the IR receptor of the TV or audio system.
Also verify the remote settings for controlling the intended device.
