No TV subwoofer output through ATV 4K
Using 2 latest version HomePods and Airplay 2 subwoofer. Works great watching content from my latest version ATV 4K. However, when watching content from my TV (with the ATV 4K connected to the eARC input on the TV and settings set to allow TV sound through the ATV 4K) only the HomePods play sound with no sound from the subwoofer. Why? Am I missing a setting or is this not possible?
