Question

Amazon Fire TV with AMP

I have an Amazon Fire TV stick and I would like to hear the TV audio through a Sonos AMP. I do not plan on adding a soundbar. The entire setup will consist of only the amp and a pair of sonos in-wall speakers.

I found an old article (5 years old) detailing how to extract audio using an HDMI audio extractor along with a sonos optical audio adapter, which seems rather archaic…

So I have 2 questions:

  1. Could I just connect the Fire TV to the TV and using the HDMI/ARC connect the TV to the AMP? Would I be able to adjust the Sonos volume though arc?
  2. Could I then still create a group in the Alexa app combining an echo device to the amp to stream music trough it WITHOUT using the sonos app? How would that work if I’m already watching TV and play music through Alexa at the same time?

Sigh second long post the forum has lost.

You can connect the Firestick to the TV HDMI in and the Amp to the Arc eArc output to play whatever the TV is showing.

The volume control buttons, App volume control and the TV'S remote should all controll volume.

Can't help with #2.

For #2 you could attach Fire TV to an HDMI audio extractor splitting Fire TV’s output to HDMI and stereo audio. The TV’s HDMI-ARC output would connect to AMP’s HDMI input and the extractor’s stereo audio output would connect to AMP’s Line-In. I’ve never tried this. but I expect that you could speak to Alexa and send TV or Fire TV audio to the speakers attached to AMP or, if there are other SONOS units in the system, you could select AMP’s Line-In as the input for these devices.
