Have been using the arc on my sony TV for a year. All of a sudden it won’t let TV sound come through. The TV says it’s connected to external speaker. When I unplug the hdmi it goes back to TV audio.  Then when I plug it back in it goes to external speakers but no audio will come out of arc. I can play music from Sonos app on arc but no tv. When I hit the up and down on my TV remote the arc status light does illuminate. Please help. Diagnostic number 815805473

Are you using set top boxes as the source?  This may be a HDCP  issue, when it thinks it needs to protect copyright, the audio is muted.  Can you please power down the TV, HDMI Splitter (If you have one) and any Set top boxes.  Then power on in the same order, letting them boot before moving on to the next device.
