Apple TV not playing sounds through TV speakers when disconnected from HomePod mini.
My 2020 Apple TV 4K is connected to a Polaroid TV. About a week ago the sound stopped working through the TV speakers. When I tried connecting to my HomePod mini the sound would come out of both the HomePod and the TV speakers, and would go fully mute again when I disconnect from the HomePod. The HomePod is in another room so I don't want to use it for the TV. The sound also woks through my AirPods Pro.
I have tried unplugging the HDMI cable, restarting both the TV and Apple TV, and checking all sound setting on both TV and Apple TV.
Thank you for any help!
