Optical supports 5.1.
You’d need to get an external ARC/eARC device to take the signal from your devices feeding the TV, and supply the extra channels to your Sonos. Or, purchase a newer TV that supports ARC/eARC. Fortunately, right now, there isn’t that much Atmos content, but that continues to change over time.
Do you have HDMI-ARC?
EDIT: Or use a “box” as Airgetiam suggests.

I didn't realize that was an option,I'll look into it, thanks.
There is the HD Fury Arcana, the Feintech VAX04101k, and the OREI HDA-935. You can also order from those links from the companies directly, or check your local retailers for availability. Amazon may carry some, depending on location. At this point, there may be more manufacturers, I haven’t been keeping track.
Thanks for the tips, I have decided to switch the TVs around in my house to accommodate for this, I'm happy so far!👍
