Pop_OS defaults to headphones when headphones are not connected, it should switch to built-in laptop speakers by default

All of a sudden, my laptop decided to detect headphones when no headphones are connected. I have tried using pavucontrol which shows speakers (unavailable). Even though moving the volume makes the sound come out of the built-in speakers (suggesting that the speakers do work!,right?) Though the headphones still remain mistakenly connected. I also tried using hdajackretask as suggested in the post here though it seemed confusing and I am not sure how to read the output from

/proc/asound/card*/codec\#*

But this is what I got https://pastebin.com/Z117DbR6 However doing grep -i jack gives me

I think it says HDMI, because I use the thunderbolt jack in my laptop to connect to my monitor. (Though I am not sure, because the port it connects to in the monitor is a DisplayPort specifically) Any help would be greatly appreciated. I am new to linux, minor troubleshoots are fine for me, however this time I am not sure if this is even a hardware issue or not.
