I've had the same problem it's been driving me crazy.

Here's what worked for me edit the alsa options

If I run alsamixer I don't see any mic channels. (Press F4 for capture)


sudo nano /etc/modprobe.d/alsa-base.conf

add the following line at the end

options snd-hda-intel model=laptop

Another post said restart alsa with sudo alsa force-reload. This does not work. Restart the laptop completely.

After restarting run alsamixeragain. This time F4 yields


Notice that Mic B is selected for capture. Change that to Mic F


That's it now the regular sound control should show mic input.

I've opened a terminal and type alsamixer. This will open the alsamixer in the terminal. Hit the 'F4'-key it showed me the 'capture' device settings. Then the 4th item displayed as Mic, I changed this to 'Internal Mic' (click array down/up key to change).

Once done, I checked in 'system-settings' --> sound --> hardware and I saw the missing lights appearing. Did a test with 'sound record' and this was working.

Hope this helps

Be sure that your audio profile is set to "Analog stereo duplex" in the System settings -> Sound configurations. This solved for me, because it was configured for "analog stereo output" only. You might want to change your audio profile only when you're going to use an HDMI output, for example.
