Fedora stopped detecting internal laptop microphone

Hi,

A few months ago, still with F36, one of the kernel updates has led to my system stop detecting my internal microphone (Lenovo G500), which previously had worked for years with previous versions. I never managed to solve this issue, and unfortunately now that the problem still persists with F37 I am considering switching from using Fedora.

Symptoms/things I’ve tried:

  1. The microphone doesn’t show up in input devices at all, and using pavu it shows up as “unplugged”.
  2. In alsamixer I am able to choose “HDA Intel PCH” and a microphone appears there but choosing it, unmuting it or playing with the intensity does nothing.
  3. I’ve tried different settings for /etc/modprobe.d/snd-hda-intel.conf that appear on the internet, the most common being “options snd-hda-intel enable_msi=1” but also “probe_mask=1” etc.
  4. “wpctl status” gives the following relevant results:
        73. PulseAudio Volume Control                                   
             46. monitor_FR     
             48. input_FL        < CX20757 Analog:capture_FL	[active]
             62. input_FR        < CX20757 Analog:capture_FR	[active]
             78. monitor_FL

Any ideas for how to get my microphone working again would be greatly appreciated!
