I have multiple Sonos speakers in my living room, but if i change the volume by GA voice it only changes the volume on the one that is 'listing'. This is really annoying and removes the use of voice commands for sonos. It's quicker with the app then changing the volume for every individual speaker by voice...
Did i miss something?
These would be perfect:
'Volume to 30 percent'
'Group volume to 30 percent'
'All Groups/Speakers volume to 30 percent'
