Hi there,
I've had a sonos arc approximately 1 month and had no issues. Nothing has changed and now tv stays muted when I try to play volume through arc. No cables have been changed, nothing has been damaged. It just decided not to work. I try to change volume and unmute with tv remote, and it just shows mute symbol. Tv will play volume when I change the output. Sonos arc will play music from phone.
Any tips would be appreciated.
