Sonos Connect automatically switching to line-in (turntable) even when it is not selected as source

I've been using my connect along with a turntable on the line-in for years, but recently switched out to a new Denon AVR (AVRX3500H). I have the Connect wired via Toslink to the AVR Media Player input and the pre-out on the AVR to the "input" on the Connect. Same wiring scheme I had with my old AVR, which worked flawlessly by the way.

The issue is that every time I open the Sonos App and try to play from a music service like Spotify for example, it starts to play briefly, but then automatically switches to line-in as the source and the music stops. I can hit play again and it finally starts playing and continues, but as soon as I try to switch tracks or change the source it happens again. I've tried changing the auto-play groupings as well as the line-level impedance, but no luck. Not sure what I'm doing wrong here. Everything is up to date and I've tried searching through the forums and via Google with no luck finding users with a similar issue. Any thoughts or advice here is greatly appreciated.

You're spot on regarding the old setup (if I remember correctly!).

Couple questions though regarding this statement:
(2) TT -> AVR ZONE2 -> CONNECT Line-In -> CONNECT Line-Out -> AVR -> AVR speakers

I don't think I fully follow this. If I'm reading this correctly, does this mean I lose other music source ability?

You're saying connect the TT to Zone 2 Pre Out? Then Connect IN to Connect Out? How does the signal from other sources make it's path to AVR? Via OPT 2?

You don't need to change any physical connections now that you have it working.

First, I should say that I'm not necessarily recommending this approach. Second, I don't have a representative Denon AVR, so I can't test whether my advice is correct.

Caveats over, these are the required configuration steps:

(1) AVR: Switch on ZONE2 and select the source you want to listen to (e.g., TT)
(2) Sonos: Select Living Room Line-In as the source for the Living Room zone
(3) AVR: Main zone, select the Sonos CONNECT as the input source

This sets up the path I was describing. Of course, if you want to listen to something streamed via Sonos (e.g., Spotify), you only need step (3).

This is what I was missing!
(3) AVR: Main zone, select the Sonos CONNECT as the input source

I'm going to try this later today, but I'm betting that's what I wasn't doing!

Thank you again so very much for your help! I'll let you know later today.

That doesn't work. I think because in order to hear the TT through the AVR, I have to have the AVR selected to PHONO source (using AVR's phono preamp).

If I'm listening to other sources like Spotify for example, I change the input on the AVR to CD and I'm good. When I change the Input on the AVR to CD when I'm on line-in, there's nothing there because the TT is connected to PHONO.

Make sense? See why I'm struggling?

It's not a HUGE deal, but it would obviously be nice to be able to control the volume from the app on the main living room zone versus having to pick up the Denon remote or use HEOS.

I still can't help but think there's something I'm missing.

/edit

Also in case it matters, when I goto Sonos settings for line-in source name on the App, the box is empty and there is a blue ! to the right of the empty box. This has been happening. Not sure what's up there.
