Headset mic not working, Acer Aspire E5-473-58v9, Ubuntu 20.04

je flag

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/alsa-base.conf by adding

options snd-hda-intel model=alc255-acer

Afterward, 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,dell-e7x 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!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
