I have a Sonos Arc and Sub in my living room that’s primarily delegated to TV use, but occasionally I’ll AirPlay audio. The AirPlay volume defaults to the last volume setting from the TV, which is too low, so I crank the volume. Later when I return to TV the volume is way too loud for the TV and blasts the whole house without warning.
It would be great if the Arc could remember separate volume setting for the HDMI input vs AirPlay and recall them when the relevant input is active.
