I don't think I've disabled anything.

It might have worked with Windows 8, but I had installed Arch soon after
obtaining the laptop.
Second. When I plug in these headphones, I can't use the internal
microphone on this laptop, it mutes. (AFAICT) These headphones do not have a microphone built in, they're just an ordinary pair of headphones. However, I was given a workaround in #alsa on freenode. In order to use the laptop's internal microphone with my headphones plugged in, I have to do : sudo hda-verb /dev/snd/hwC1D0 0x22 SET_CONNECT_SEL 6 — it works, but it isn't really ideal.

Do you mean disable jack detection cannot work around this jack detection fault ?
Using hda-emu, the driver seem select internal mic when jack detection is disabled on startup
How about disable jack detect using hint jack_detect=0 ?

you have to select mic jack using capture source and manually mute the
