Internal microphone not working on Dell precision 7530

ru flag

Problem: Internal microphone does not work

Question: How do I get the microphone to work?

Setup:

  • Model: Dell Precision 7530
  • OS: Ubuntu 22.04
  • Kernel verion: 5.17.0-1025-oem (recently switched from non-oem)

I already tried:

  • Selecting Stereo duplex in Pavucontrol
  • Unmuting in Pavucontrol
  • Checking microphone levels in Alsamixer (Though there are only "headset" and "headphone" options and none for an integrated microphone)
  • Reinstalling alsamixer and pulseaudio
  • blacklisting "snd_hda_intel" in /etc/modprobe.d/alsa-base.conf
  • Installing SOF firmware and topology binaries
  • Testing external mic on headphones with a 3.5mm jack and on a usb webcam (both worked out of the box)
  • Checking other answers

(Hopefully) relevant info:

After further digging around I figured it out.

My laptop does not have an internal microphone at all.

It may come as a surprise, but apparently not every laptop does have an internal microphone.

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.
