Acer Laptop Combo Mic/Headphone Jack Issue

Hi All,

Hoping I can get some help here. I think I'm missing something stupid. I have an ACER laptop (Timeline M5) running arch. I use ALSA without pulseaudio. My computer's inbuilt mic is recognized OK. THe computer has one of those 1/8" inch combo jack's (3 connections) for headphone + mic like an android phone. When I plug it in ALSA routes the sound perfectly. The mic howerver is not used. Here's some system info.

aplay -l

In /etc/modprobe.d/alsa-base.conf I have tried:
options snd-hda-intel model=laptop-dmic

As well as models alc271-dmic  and acer

with no change. Basically the internal mic stays on which is workable but there's alot of noise from the fan I'd love to get my headset used. Fiddled around in alsamixer with all of the channels. There's never a channel showing external mic or anything like that.

Any help would be appreciated!
