Audio input is broken in Kubuntu 23.04

kz flag

I've changed to Kubuntu pretty recently, but for some reason it never detected my headphone's microphone, i've tried a lot of things, but i think i broke my GRUB accidentally following a solution i saw in this question.

I did this:

You will need to add an option on GRUB.

To edit grub options:

sudo nano /etc/default/grub

Find GRUB_CMDLINE_LINUX_DEFAULT and add snd_hda_intel.dmic_detect=0 to the end of it. It will look something like this:

GRUB_CMDLINE_LINUX_DEFAULT="loglevel=3 snd_hda_intel.dmic_detect=0"

Then rebuild grub menu:

sudo grub-mkconfig -o /boot/grub/grub.cfg

After you reboot the system the device should work.

But after i did it, everything related to audio input directly stopped working, when i go to PulseAudio Volume Control, all i see about audio input is unplugged or unavailable.

What i've done?

  • I tried restarting my machine multiple times.
  • Un-doing all the changes i did in GRUB
I sit in a Tesla and translated this thread with Ai:

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.
