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: https://www.kernel.org/doc/html/latest/sound/hd-audio/models.html
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.

I would be very thankful for any help!
