UN55MU8000F keeps changing ARC audio output from Digital to PCM.
IN the last week the TV, UN55MU8000F, started getting loud and soft and loud again. I went looking and saw that it was sending PCM from the TV to the Denon Receiver. Dolby sounds fine and then the volume gets real low and I see PCM is lit up on my receiver.
I get it back to Dolby and sounds fine again.
My Firmware is 1280.
I looked on the site for the firmware and could only find 1270.3.
I am on auto updates, so 1280 got put on there by Auto Update.
Was there a rollback that I am unaware of? I have not tired installing the one on the site, because I do not know if it would cause any errors.
