Do try mic2.
I'm surprised you don't get a ton of feedback through the speakers.

you could have a index issue in /etc/modprobe.d/sound.conf.

Yeah your using a different distro than me.
Furthermore the index issue is usually if you have 2 sound devices. 1 onboard 1 usb(like your cam). This usually applies to usb headsets.

Not 100% sure but I think alsa-base.conf is the equivalent.

Yeah alsa-base.conf is it:

Does any of that help? It's gibberish to me

That file should not need editing as you only have your onboard sound device and no usb sound devices.
If there is a way to stop pulse audio temporarily(for testing)
Or if available updated alsa(try building from source perhaps)
I am not too familiar with pulse audio and I'm running out of ideas.

Well thanks a lot for all your help, I might just have to go mic-less for now

You can order your modules as kind of shown above.

options <module> index=0 Would make it your card #0 / primary
options <module> index=1 Would make it card 1
...

It gets a bit tricky if you have two cards. Especially if both have the same driver / manufacturer / model / chipset / same same same...

It could be a plugin power issue. Not all soundcards provide the little bit of voltage needed to run electret type mics. If that's the case you might need a battery box to bridge that gap and provide power. Or put some other device in the middle like a Zoom H2. I've got a giant squid mini mono and a battery box(9V). And I've got an ATM75 headset mic too. Runs on phantom power, or a single AA battery.

If you can run say your CD player into the mic port at a very low level (volume 1-10, so about 0.5). And that records, then you know it's the mic / plugin power thing. If it works in windows on that same hardware, you can probably rule that out now. According to configuration it looks fine. But you don't appear to have any signal coming into the mic port. Which is odd since many devices at least have some self noise when nothing is plugged in. So sox's stat should show values above 0.000000 IMO.

$ lspci -v | grep -i "audio"
$ lspci -n -s ##:##.#
(where the ## stuff is the first 7 chars of the other result. For the device you're interested in)

You might also check if your headset mic has an on/off switch.

It must be getting late. If you're hearing it through the speakers, then plugin power isn't your issue. Although putting a cd player into that port might help debug things since it's a relatively hot and constant signal where you mic might be set too low to notice without amping in post. sox's stat would likely be > 0.000000 if that was the issue, but still some mics provide VERY weak signals. Weak enough to require a microphone preamp (pre-soundcard) to be of use. Again, since you are hearing it through the speakers, not likely your issue either.
