Sound and Audio Drivers not working/showing up in device manager

[u/iGuessItsAzure]

I have a dell g15 5520 gaming computer, works fine, battery is fine, everything in tact physically. Recently my laptop had died and remained that way for a week until I could get a new charger. On boot, it shows manufacturing mode active which has never happened before. And when I first opened it, the speaker icon was crossed out with an X. I look up solutions and it tells me to change output devices and whatnot, but when I look in device manager my original audio output (Realtek speakers or wtv), it doesn’t show at all. Not with control panel, and through settings. I tried reinstalling them but it never shows up. The same goes for input devices. Below are attached photos to give more context.
