My lounge is at one end of the house and kitchen/dining room at the other—there is no wall separating these two spaces. Due to the the 5.1 nature of sonos systems (I can’t make one big group) I have two separate speaker groups. Two sonos Ones in the dining room and a beam and two sonos Ones in the lounge. What suprises is me is there is no easy way to simply match the volume of these two groups. They don’t even default to the same volume when connected. I have long thought this feature would simply appear its need being immediately apparent to anyone in this situation, which I suspect is a lot of people. But it hasn’t so I’m raising it here.
Different speaker models have a different audio output at the same volume number.
A volume limit set on a device can also impact on the audio output at any given volume number.
Therefore, a method to quickly sync all rooms to the same volume number wouldn’t necessarily mean the rooms are all playing at the same volume, so whilst it may benefit some, others would want the sync based on actual volume dB output.
Thanks for the technical insight. I think all of what you say would need to be taken into consideration. However I would say these are UX challenges to solve and are not insurmountable.
Take device output; In use case I’m describing both speaker groups are playing from the same source device so we can assume the output of the device is the same. The sync capability would only appear in this situation.
Your second point: Different speakers output different db is a good one. Indeed this is the case with my setup. However these db outputs are known entities to Sonos. So its a communication challenge not a technical one.
Let’s break it down. When two speaker groups are “volume synced” we need to communicate to the user that despite the volume numbers being different (between speaker groups) these correspond to the same db. One approach could be the show in parenthesis the db of both speaker groups at a specific volume level so that the user can see they are indeed matched. For example: vol 17 (35db).
I think it could actually be really cool to know the decibel being outputted at a specific volume. Which would be a secondary benefit of this feature.

What do mean by “Due to the the 5.1 nature of sonos systems (I can’t make one big group)...”
Click the speaker iCon in the now playing screen and select “Everywhere”. See Picture
Although, it won’t resolve your one click feature request.

Substitute ‘group’ for ‘room’.
They simply mean they can’t have all their speakers in the “Lounge”.

Thanks for the reply….but this still doesn’t make sense to me regarding the OP’s statement that I quoted. OH...well!
Now I have to go create a topic regarding the computer app.

Thanks for responding
Appreciate both your responses on this forum!
No doubt your post will be marked as a feature request when seen by a mod.
The option to create saved Groups is available when users have 3 or more rooms in the Sonos app.

One possible addition to this menu would be for user to also select a default volume number for each room in the saved group, which would then be applied when the saved group is chosen in the app.
Hi
