For years been looking up answers why my SL one left surround sound keeps disconnecting. Did all the troubling shooting, unplug, reset, move the speakers closer, get a WiFi boosters. I may figured out a partial solution. I haven’t added the Apple Music account and haven’t lost the speaker since. So reboot the system and don’t add the Apple Music.
Surround sound disconnecting
Not sure I understand this, but if it works for you….
Generally speaking, surround speakers connect to a ‘hidden’ 5Ghz signal emitted by the Sonos soundbar. While this signal can’t be seen in your controller, or in your router’s reports, it is susceptible wifi interference. They don’t, once set up, connect directly to your WiFi signal, no matter how many ‘boosters’ you use.
It’s always a good idea to reboot a system, including a router. Electronics can get hit by various issues that can get cleared by reloading the OS, which happens when you unplug the device.
I’m a tad confused about your ‘workaround’.

There have been issues mentioned when streaming Apple Music lossless. Could you have been streaming Apple Music with the surrounds set to full for music when the assumed discount occurred?
Welp I guess it didn’t work. But it lasted until the latest update. Now having the same issue with my left SL dropping off again.
Boosters and extenders are often a problem for Sonos, best to go to a mesh setup instead.
What do the signal strengths look like for each Sonos?
Are you on S1 or S2 software?
Are you using any wired Sonos / Sonosnet?
If so have you verified that you have not selected "disable wifi" and turned off the radio essential for proper surround operation?
Not sure how you don't have the signal strength then, well unless you are on a really old release of the App. Update to the latest App and firmware, power down all Sonos, reboot router and controller and power up your Sonos. Once that is done you will see the signal strength screen I copied/pasted from my current S2 app.

If it isn't there you may have something VERY wrong, I checked on a gen 1 Play 5, I don't have a One SL powered up to check it on so I could be wrong.
Physically swap the units. Does the issue belong to the location or the unit?
