Continue having trouble getting my laptop audio to play thru Sonos Amp 2.1 system

You have to choose  Brown is S1 and Black is S2.

Neither apps or devices will communicate across the S1/S2 divide, all devices and controllers that you want to work together MUST be on the same S? version.

It doesn’t make sense to me that the Amp could be seen in both the S1 and S2 apps. Which was why I refrained from commenting. Also, the Amp would have come with S2. He would have had to downgrade it to S1. Not something done without meaning to. I remain confused :)

Well noted…..sonos tech support did NOT point this out...but I notice extra work that I have to do….all amp set up was done on the black sonos app on my phone….except for setting up line in additionally on the laptop brown app.

The extra work is while the amp recognizes the different sources  tv, sonos library in the sonos app  (brown) on the computer, and switches all back and forth ok...I HAVE to manually adjust volume dramatically up or down on my computer task bar and/or volume in sonos brown app on computer each time I switch back and forth...otherwise sound comes out at full volume this SEEMS to be the only problem thus far…????

Thanks again for input….much appreciated..?? 

The Windows app is in maintenance mode and does not receive feature updates. That’s why it is brown, not black. Since all apps are just remotes to the system there should not be a difference in behaviour of the system depending on which app you use.

There will always be a difference in volume between different sources.
