I’ve seen this question/issue raised several times and I want to add my vote for this enhancement to the Sonos One. It is really a nuisance not being able to control the volume of the Alexa / Google Assistance separately from the volume of the music.
Control for Alexa / Google Assistance Volume Independently from Music Volume

Thanks for your suggestion. I’ve sent your comments on to our development team for consideration 
Hi! I'm also having this "problem" with my new Sonos Arc. When I watch TV I happen to turn down the volume considerably while watching and when I turn off the TV the volume remains low. In this way, when I use Google assistant, with the TV off, the volume is too low and sometimes you can't get it up directly from the soundbar because your hands are busy and I can't hear the assistant's voice. This problem makes the built-in assistant function practically useless. Is there a fix for this problem?
