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?

Your issue sounds like something is wrong with the Fire Cube or its settings. This is a Sonos community have you contacted support for the Fire Cube. So unless someone sees this post who has experience with a Fire Cube you may not get the assistance you need. For the record I know nothing about a Fire Cube.

It might be an issue with the TV and CEC, especially given that bedroom Firestick. Of course, I don’t use one either, but before calling Sonos, I’d be tempted to reboot the TV’s OS (and probably check for updates, first) by unplugging the TV from the wall for two minutes.

Did you reset the Amazon remote to match the new TV or is it still set to match the old one?

In the Fire TV Cube settings, select Equipment Control → Set Up Equipment Again. That will get your MBR cube set up for it’s new location & devices.

Or you could select Equipment Control → Manage Equipment → Soundbar if everything else is set up ok.
