I've had to reset my ARC and I use my 2 SL1’s for surrounds.
I have a feeling it used to say ARC + Surround …. ?
any help would be appreciated 👍

Any time you see a ? on those screens, that means the Sonos system is having an issue connecting to and using the speakers designated as a ? and they’re most likely not working.
