I have a Fire TV Cube connected by HDMI to a Sony TV. I have an ARC output from the TV connected to the Sonos ARC. I also have Verizon FIOS TV. Intermittently, the sound from the ARC will stop (go silent), while the video continues on the TV. What I discovered is that removing the power plug from the Fire TV Cube immediately restores the sound. Any idea why and how this can be remedied? Very bizarre.
