I have 4 Sonos One speakers setup in a group and I am using Google Assistant and Pandora to play music. I say "Hey, Google, Turn up the volume" and the speaker that seems to be closest to me increases but none of the other speakers in the group increases.
I would like to have the entire group of speakers volume increase with GA voice control not just one speaker. I can't seem to find a way to make this work and change the volume all speaker in a group with a single command . I constantly need to go to my Sonos App and use the volume sliders to re-sync the volume levels so they are all the same again. The other option would be to go to all 4 rooms separately and have GA increase the volume separately.
