Low audio quality, no microphone detected from combo jack, Acer Nitro V 16

Hello y’all, this is my first post in the forum.

I set up yesterday my new Acer Nitro V 16 ANV16-41 with Endeavour. After fixing some BIOS issues I’ve noticed that the audio quality is bad, (not the case when using the same headphones on my old Windows laptop). I’ve also noticed that when plugging in the headphones, the audio gets detected and switches accordingly but not the microphone (it keeps using the internal one). Any guidance on how to solve it? I’ve searched stuff online but I’m not sure what to do, already tried some stuff (and reverted the changes when it didn’t work)
