Okay, Im sure this question has been asked before but i cant seem to find a fix/answer at all only somebody saying to set a volume limit (which wont work in this case and ill explain why later on)

My Setup: 2 Sonos One speakers either side of our sofa and 2 sonos in-ceiling speakers connected directly to the sonos amp which is connected to my Samsung 75” smart TV using ARC-HDMI

Volume levels for following scenario:  1/10 is really quite  and 10/10 is really loud

Scenario: Watching TV volume at 5/10 everything is fine. Turn tv off and cook dinner. Ask Alexa to play a song on Spotify on the Sonos ONE (have grouped them so they also play through the ceiling speakers). Volume is now 10/10 and neighbour can hear my music just as well as I can. Volume is so loud it almost punctures your ear drums. Turn the volume down to 5/10 to listen to music during dinner. After dinner you turn the TV on to watch a film and the volume is 1/10 and you cant hear a thing so you turn it up to 5/10 again and next time you switch to Spotify its 10/10 again and your neighbours banging the door down for the 5th time that day.

There just has to be something/someway to stabilise the volume between sources and not have to resort to manually turning the volume down pre-emptively.

If i set a volume limit all is well and good until i then want to watch TV as the volume limit is then set to low to hear the TV (yet Spotify is perfectly fine volume).
