You would need to unbond the surrounds/Sub from the Ray, to then bond them to your laptop Ray - which is a bit of hassle (to say the least) - However, have you tried grouping the two Ray (rooms) instead (assuming they are running within the same Sonos Household) and adjusting the Music Audio playback to ‘Full’ and adjusting their ‘TV level’ and ‘TV Dialog Sync’ slider controls in the Ray’s room settings, depending on the type of audio (Music/TV audio) you are listening to? 

I think perhaps playing around with the TV/surround audio settings in the Ray’s room settings in the Sonos App might perhaps work for you, particularly with ‘grouped’ stereo music playback.

I would just have a play with the available Sonos tools and see what you can achieve through ‘grouping’ the two Rays together.

Good idea. I’ll try this-- grouping the two Ray rooms (that are actually a single room) together. This solution means that both Rays would be operating at the same time rather than one at a time each with the Surrounds.  But maybe having both Rays running simultaneously will sound OK. I suppose the question is whether there will be noticeable latency coming across as echo between the two Ray sound bars. Thanks for the creative solution.

@Ken_Griffiths This solution works super well. No issue with latency. Although both Rays are operating together-- along with the Surrounds/Sub-- everything sounds great. Many thanks.
