How can I connect an external microphone to my Acer Swift 1 laptop ?

It has a built in mic, but I would like to connect an external one, and sometimes even a line-in cable, to capture radio broadcasts with an appropriate cable.

Ouput of different sound related commands:

My laptop has a Realtek soundcard, driver: snd-hda-codec-realtek.ko
Maybe it has some kernel option, to apply in grub, which switch the mic input.
When I open the driver binary file, I can see the string: "Headset jack set to mic-in mode"

Re: How can I connect an external microphone to my Acer Swift 1 laptop ?

Can you see your external microphone and line-in ports in pavucontrol 'Input Devices' tab for 'Built-in Audio Analog Stereo'?
If yes, you can add 'set-source-port' to /etc/pulse/system.pa (or to ~/.config/pulse/default.pa for per-user configuration) or change it with pactl in runtime.
If no, it means input ports aren't described in profile for your soundcard. In this case you can try to run alsamixer, press 'F6', select your hardware card and configure sources for 'Capture'.

Unfortunately I can't see the external microphone, only the built in mic.

Earlier I wasn't able to switch external mic neither in alsamixer utility. That's all what I can see:

You can reconfigure how the jack behaves in hdajackretask you need to stop pulseaudio and then run hdajackretask to reconfigure how the jack behaves.

Also please don't embed huge images like that directly and just link to them.
