Samsung TV switching back to PCM since few days.

I know it’s a TV setting, but since the TV hasn’t had firmware updates in a while, it makes me somewhat suspicious of a possible update to my Sonos Arc Ultra soundbar.

For the past few days, even though I have the TV set to “DD+”, it randomly switches back to “PCM” on its own. Obviously, when I play something in Atmos or DD+, it stays in PCM until I manually change the TV settings again.

It’s very annoying—every time I want to watch a new video, I have to go into the TV settings just to check if everything is correct.

The TV is a few years old, but this didn’t happen before on my Samsung MU6100.

Maybe a factory reset on the TV (Not your Sonos) would restore the way it was working?
