I have a new arc bar all hooked up but when I turn my tv on after a few hours it defaults to speaker then the arc comes in about 5 min later
plus , with my cable box plugged into the tv the Sonas app says that I have an hdmi interference issue .
i then have to disconnect the cable box hdmi then the sonas plays then I can hook back up the box
Do I always need the app up and running when I use the bar ?
