PS5 - Surround Sound 5.1 Linear PCM - NOT WORKING FOR MONTHS

@teeeeewwwwww I feel like mine wasn't that bad up until recently but a dead speaker caused me to upgrade my system a bit and now I'm noticing a massive dead zone of audio. My back speakers will kick on for a hot second if I have it set to 7.1 (though I don't have the setup to support that) and not at all if I have it set to the correct 5.1. Plug in my headset and it works absolutely fine but I hate playing with my headset on for hours at a time.
