I have a brand new LG TV. And a brand new Beam. It’s hooked up through the ARC port on my TV. And the audio continually goes in and out. One sec, everything is fine. The next sec, the dialog is muffled and you can barely make it out. This happens whether I’m watching stuff through my cable box. Or streaming from apps on the TV.

The first thing to try in this situation would normally to be to follow
However, as you reported a flashing red light from the Beam (not to be confused with a flashing orange light), I recommend you get in touch with our technical support team, who have tools at their disposal that will allow them to give you advice specific to your Sonos system.
