System switching from sonos port (Bedroom) back to sonos amp (Living Room) without prompting

Sorry, that is just too hard to read.

Why did you not  use the forum default font?

Well...thank U for taking the time to respond…..

​@Stanley_4 has a point.  Why would you purposefully post in a difficult to read font color when you are looking for people to help?  Then double down with a sarcastic reply when someone points out that your post is difficult to read?

Thank You...I will retype so everyone can read….

SONOS STERO SYSTEM SETUP: Sonos system is currently displaying correctly in brown app on computer and correctly on black app on phone…

BEDROOM SYSTEM 2

Sonos Port > Fulode EQ > smsl power amp > chartwell passive spkr: velodyne powered sub

SPECTRUM INTNET…LENOVO, SONOS AMP, PORT ALL ETHERNET HARDWIRED

ISSUE: set to living room..all good…set to bedroom, drifts back to living room….any change in source when set on bedroom, drifts back to living room…both EQ’s on all the time…

Can you specify what you mean by ‘drift back to’, please?

I’m not sure if these are separate systems, or just different rooms in the same system.

I think ‘black app’ means both are S2, though, as that’s the color of my app on both iPhone and iPad.
 

drifting=returns to system 1….2 separate systems...one sonos amp….one sonos port...thanks...

Are the two Fulode EQ you list, the same device? Is the Sonos Amp set to Autoplay Line-in?

Still not clear on what “returns to system 1” means. What returns to system 1? I think you need to be more specific in your descriptions. It’s kind of difficult to figure out what you’re talking about.

I still don’t know if this is two rooms in one system, or two different systems. 

Seems that you are using the Amp and Port as audio streamers in their respective rooms (setup). If you are somehow starting separate streams of the same audio on each device from the same source and then grouping them together therein lies your issue. You should start stream on either the Amp or Port and then group in the other.
