@Mark_225
I can confirm what you described. But imo that is made by design and a feature to set an average volume when using tv audio swap. To keep the same level wouldn’t make sense, because for Ace and the soundbar the same level sound quite different. And to keep the levels separately for both might be a technical problem. Not sure at all, but for me the current solution works fine.
It resets the sound too loud on both devices for me - but I can see why my request probably isn’t achievable, particularly when I’m not using the app to swap the sound. -Mark
I'm experiencing this issue as well: it doesn't matter which level the Beam or the ARC is on when switching. Somehow there is, exactly as you describe, some kind of predetermined volume level that kicks in. Can't seem to find a setting either to change the behavior.
Pls @SONOS : fix this by either maintain the level that is used in the speaker or let us adjust the predetermined volume in a setting for the ACE headphones.
