System doesn't detect any microphone

Hi,
I have just finished installing Arch on a nine year old desktop pc and everything is working wonderfully except for one thing: the microphone. The pc doesn't have a built-in microphone so I can't rely on that. However, my headphones do have a built-in mic but the system won't detect it. The headphones work correctly though. I have GNOME and when I go into the settings my headphones show up in the "Output" tab but nothing shows up in the "Input" tab. The headphones' mic worked under Ubuntu so the headphones are not the problem I suppose.

I followed the ArchWiki guide to try and resolve the problem. Specifically, I did

$ arecord --duration=5 --format=dat test-mic.wav
$ aplay test-mic.wav

This recorded the output of the headphones.

Also, I tried pluggin in a webcam with a built-in mic. Again, the webcam is detected:

$ dmesg | tail

but no sign of its microphone.

Can anyone help me?
I'm new to this forum so I hope I haven't posted this in the wrong section.
Thanks in advance.

EDIT: I think I found the problem. Being the pc a bit old, I don't think the headphone jack supports both audio and mic. Is there any way to confirm this?
