Morning all . Can anyone help.
I have a Sonos arc connected to my lg c1 via the arc hdmi. A Panasonic uhd player via hdmi and ps5 in other HDMI. TV streams Atmos from say Disney no problem and atmos films on the player again no problem. However when I put an older film in. Like say the other day was watching the 4k of death becomes her. I was only getting stereo pcm. I have tried looking through endless threads on here and changed various settings but still only get pcm. Surely my older films should at least be able to do 5.1 . Anybody got any help at all
