Sorry I should’ve explained better. I want to control the sub volume separately, and was advised the only way to do this would be to move sub to another room using app. However each time i remove sub and reconnect it defaults back to the same room
A sub cannot be its own room. It must be bonded to other speaker(s). You can control the Sub output from Settings > Room Settings > (room w/ Sub) > Advanced Audio > Sub Settings.
