Fire Cube with Sonos Amp not adjusting Sonos Amp Volume

In my front room, I run the TV audio through a Fire Cube. I have two Sonos Amps connected by HDMI-eArc. One of the Amps powers a pair of front L/R main speakers and the second Sonos Amp is connected to a pair of in-ceiling rear speakers.

I have used this setup with no issues for over a year now until recently I started having issues with the Fire Cube losing internet connection sporadially. To test whether or not it was the Fire Cube or if it was something else, I swapped out a different Fire Cube from my Master Bedroom (MBR).

I took the Fire Cube from my MBR and connected it to my front room TV. Everything works fine, the sound comes on through my Sonos Amps EXCEPT now I am not able to control the volume of the Sonos Amps using the little Fire Cube remote. The volume is adjustable through the Sonos ap, but that is not ideal.

Is there some setting on the Fire Cube that I need to adjust so that I can adjust the Sonos Amps volume using the Fire Cube’s remote?

@Pools-3015 is correct. You need to reconfigure the Cube to manage other devices using CEC.

Go to Settings on your Fire TV menu.

Select Equipment Control.

Choose Manage Equipment to add or configure devices like your TV, soundbar, or audio receiver.

Follow the on-screen prompts to select your device brand and test power and volume functions.

You state “ I have two Sonos Amps connected by HDMI-eArc”. For future readers: you probably have one Amp connected by HDMI-ARC (Amp does not do eARC) for the fronts and you bonded the other Amp as surrounds (rear)?

That is correct
