Playbase not playing TV audio at all, suddenly

Situation:  My playbase is not playing any audio from the TV.

 

My TV is a Vizio P Series.  

 

Playbase will play audio direct from Spotify, for instance, when I select this media source in the app.  It is apparently not detecting anything over the optical audio cable.

 

I have  Roke Premeire connected to Vizio TV via HDMI, and optical audio from TV to Playbase.

 

I have power cycled everything in the chain, no affect.  Sonos app stays on the Spotify test track and doesn’t auto-detect optical audio.

 

Roku is set for Dolby Digital.  Vizio TV is also set for Dolby Digital for the Digital Output and Analog Output is Fixed.  TV speakers are “off”.  

 

I have unplugged the optical cable from the playbase and verified a red light, then re-seated it.  

 

Nothing is working. There seems to be no customer service anymore at Sonos (I have another question I emailed weeks ago and no response) so I’m grasping at straws, here.  

 

The app doesn’t seem to have a way to verify Optical Audio coming in (I had thought it would auto-detect, but apparently not).  

 

I can provide any other information.  This is extremely frustrating.  It was working literally hours ago, I did nothing to the system but turn it on again and suddenly it doesn’t work at all.

 

EDIT: Diagnostic number is 2018600420

Another odd behavior is the Playbase is not detected “Volume Up” commands from my remote suddenly, but it is detecting “Volume Down”.  It is not detecting “mute”.

 

Manually I can set volume up and down (and hear the tones when I push the buttons) but the app keeps the input stuck on Spotify and won’t Auto Detect the TV audio input.

 

I’ve verified my cable on both sides.
