Earphone mic doesn't work on Ubuntu 21.10

My laptop (Lenovo IdeaPad 330) has a fresh install of Ubuntu 21.10. During normal and regular use just after installation, the earphone mic was being recognised and it was functioning well. Then some time later, maybe a few weeks, the earphone mic wasn't being recognised. Pavucontrol says it is unplugged. I don't know if this is because of some update, because whenever I plug in my earphones, it brings up this prompt, which I didn't see previously.

(Please read the question till the end before flagging it as duplicate. Thank you!)

I click on Headset, thinking it will allow the mic to be used, but it simply doesn't. PulseAudio Volume Control still says "Headset Microphone (unplugged)". Clicking on Headphones doesn't help either.

Checking for microphone options under settings doesn't even list the external microphone

These are the details about my sound card and chip

I'm not sure about what to do and the other questions on AskUbuntu do not match mine (they are about internal microphone or about driver issues but I do not think this is a driver problem because the external mic was working previously with no issues - but I may be wrong) or do not have any answers.

Please help.

This issue can be resolved by following these steps:

  1. Find out your machine's codecs with cat /proc/asound/card*/codec* | grep Codec
  2. In my case I saw Codec: Realtek ALC236 Codec: Intel Kabylake HDMI.
  3. Go to www.kernel.org and lookup your codec. In my case it was Realtek ALC23x
  4. I chose dell-headset-multi as the other codec options did not work for me.
  5. Add the line options snd-hda-intel model=dell-headset-multi in the alsa-base.conf file by opening the file with the command sudo gedit /etc/modprobe.d/alsa-base.conf and edit it.
  6. Save and close the file. Reboot your system for the changes to take effect.

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.
