sound – Headset microphone not working, Acer Aspire ES1-572, Ubuntu 20.04

When plugging in a headset via the headphone jack, my laptop sends sound to the speakers but does not pick up any sound from the microphone.

I tried to modify /etc/modprobe.d/sound-fixup.conf by adding

options snd-hda-intel position fix=1
options snd-hda-intel model=aspire-headset-mic

Afterwards I got the option to select between headset and headphones once I plug in my headset, but no sound is detected. I also tried many other settings from this list:

dell-headset-multi and dell-headset-dock gave me similar options to select from when plugging in the headset, but still without sound. All other settings seemed to not work at all.

I also tried my luck with hdajackretask, but I really can’t wrap my head around what each setting does and blindly copying things that worked for other people has not worked for me.

Alsa infromation with plugged in headset:

I would be very thankful for any help!
