Hi, when I connect Sonos arc with a couple of years old Samsung tv, tv says a device supporting atmos connected. however, from there on the source basically changes between tv speakers and arc in about two seconds intervals. Sound never comes out from arc but tc speaker instead. So no output even for a a few second when the settings says source is Sonos arc. Using Sonos supplied cable and tested million times if the eARC connections are loose. They seem not to be loose, also have tried with three different HDMI cables. Also done all cables and equipment off for 10 minutes but no cure. What should I do next. Sonon Arc works properly when using with my another (tiny) Samsung tv so Arc itself is no faulty. Could the eARC port in the television be faulty?
