My ARC has worked perfectly, then most recently along with many others, it stopped connecting to my TV. It is also effecting the rest of my Sonos “rooms” because when I unplug the arc everything works.
spent over 4 hours on back to back days with Sonos and troubleshooting. That is literally a day of work.
Now they sent a refurbished replacement which had the same issue prior to being refurbished. Can’t have a conversation with anyone about this, just emails back and forth every couple days.
