Good Morning, I recently installed a 75 Sharp Android TV and connected my Sharp sound bar through the ARC HDMI. When hooked up this way the volume panel continues to pop up every 2 to 3 minutes. I have attempted to hook up through optical audio cable as well and tried 2 other HDMI 2.0 cables and get the same effect. When hooking up through Bluetooth or using the TV speakers this does not happen. Any assistance would be appreciated.
Seems like I am getting a little closer lol. I turned CEC off and the volume pop up disappears but it reverts to Tv speakers with no way of removing. I had a Logitech harmony 1100 remote connected to the soundbar at one point but that is long packed up. Any other suggestions would be greatly appreciated. Is there maybe a way to upgrade the soundbar firmware?
