[SOLVED] PulseAudio detects headphone but not it's external mic

Hi, I'm using headphones in my laptop and sound is working great, but recently I realize (using OBS) that the mic is not detected and the input used is from the laptop's mic. In Windows both inputs are present (headphone's mic and laptop's mic) and working great. I have pulseaudio-alsa installed. Also, inside alsamixer the volumes of "Headphone" and "Speaker" changes when I plug/unplug the headphones (as expected). I've also installed pavucontrol but the only mic that appears is the one from the laptop.

I'll leave some info that might be useful:

Re: [SOLVED] PulseAudio detects headphone but not it's external mic

Which laptop exactly? This is more often up to ALSA detection rather than pulse, try changing your snd-hda-intel line to

options snd-hda-intel index=1,0 model=auto,dell-headset-multi

check https://www.kernel.org/doc/html/latest/ … xxx-models for some other possible models (e.g. headset-mic and headset-mode or so) note that all of these will only apply on reboots/kernel module reloads

This actually works! My laptop is a Huawei so I was trying other models with no success, but the dell-headset-multi worked. Thanks a lot!

Re: [SOLVED] PulseAudio detects headphone but not it's external mic

This can also depend on how you tried to apply the parameter, the auto leading the model line is important so that the HDMI is configured with it's defaults but the headset-multi adjustment is tried for the actual onboard chip.
