In the ‘room’ for your Ray, there is a section for the surround speakers. In that section, there is a volume for the surround speakers versus the Ray. 

Ty Bruce it’s working. .I have a ray and 3play one.When I Connect play 1 in veranda it’s not possible to connect to ray a play 2 and play3 .Can you in a surround system mount 3play 1 ? Ty a lot for the help.

Not sure I understand, but I think you’re asking to use three PLAY:1s as surrounds, and the answer is no. The Sonos system (including the Ray) only supports (and requires) two surround speakers. 
 

The third PLAY:1 could be set up in another Sonos ‘room’, and then grouped when playing music. When playing the TV’s input on the Ray, there will be a slight delay between the Ray’s ‘room’ and any grouped  ‘rooms’.

Ty I will try it

Bruce I have 2 mini pad 4 and I want to install the Sonos app but I get the message I need to update to iOS 16 but it’s not possible on a mini pad to update to iOS 16 .I there a way I can download an older version of Sonos 2 

In a word: No.
