Microphone not working on kernel 5.5.9

English Hardware

Hey,
I have a HP zbook with kernel-stable 5.5.9. Was able to make the sound work after finding https://superuser.com/questions/1509312/sound-stopped-working-after-upgrading-to-linux-5-4-intel-hd-audio. Unfortunately, the mic is still not working. In the sound settings I have nothing there. I get the following output

arecord -l                                               
**** List of CAPTURE Hardware Devices ****
card 0: PCH [HDA Intel PCH], device 0: ALC215 Analog [ALC215 Analog]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

Any ideas on how I can make the mic work?

Muted, perhaps?

Nope, no input device in the sound settings
