My setup is as follows:
Sony Bravia 65"
Beam connected to TV via HDMI ARC. Ethernet form beam connected to router
Yamaha in ceiling speakers for L+R Rears connected to Sonos Amp
Sonos Amp connected via Ethernet to router
Beam works fine through TV but rear surrounds do not play from tv. If I use the volume buttons on the Sonos amp I can here the confirmation "blips" coming from the rear surrounds but it only turns up the beam. I feel like I'm missing a simple step with getting the audio from TV to go to Amp. Do I need to run HDMI from Amp to TV?

Ethernet from beam to router was bad. Pulled out the network cable tester to confirm and then made a new cable
Fire TV was set to optical out. Switched it to Dolby Digital over HDMI.
Thanks for everyone’s help!
