Sonos Beam Gen2 increases Sony Bravia TV volume by 2 levels instead of 1

Is this just Numbers, or is there really a problem?

I don't understand your reply ​@106rallye 

What do you mean with "is this just Numbers"?

Problem description: before I used Sonos, I pressed Volume up on my remote control and the volume changed from 0 to 1. After installing Sonos, I press Volume up and the volume changes from 0 to 2. This is completely unexpected behavior and a major bug that needs to be fixed by Sonos.

What I mean is, what do you actually hear? Are the steps in volume indeed bigger than using the TV speakers? Are the steps too big? Is your complaint that you cannot get the right volume?

On other TV’s, like my Samsung, you do not see any numbers for volume when you connect a Sonos soundbar. Chances are this is a TV thing.

I have an Arc connected to a Sony and yes, the volume jumps by 2 steps each time. 
I had already read about that in some review before I buy the bar.

If you have a kind of OCD (I prefer even than odd 😅) you can adjust the volume through the app, or with the voice control (SVC)

It actually goes up by 2 levels, as displayed on the TV.

I did some more research and found bug reports back to 2020 so Sonos doesn’t care to fix for 5 years… I quote a (retired) Sonos employee:

the very basic incremental increase and decrease of volume is not yet a supported feature of the Sonos App in general. However, I will be more than happy to send this to our engineering team as a feature request in considering an option to increase or decrease the volume based on numeric increments.

Thanks,  too much effort :) I will just wait for the feature to be implemented in the next years (hopefully)
