Built in Microphone Detected but not Detecting Sound? (Same for bluetooth mics) - turning mic gain up does return electric noise feedback but no actual sound capture

Initially, both sound and microphone was not working, I fixed sound by editing alsa-base.conf and have been trying similar for the mic. 3.5mm headset microphone works fine but the built in mic and bluetooth microphone do not.

I’m pretty sure the actual built in microphone is fine - but have not tested as installed Manjaro over WIndows as soon as I updated the BIOS lol…

Pulse detects ‘built in microphone’. Alsa shows - one capture device. There is also an ‘Internal Mic Boost’ and ‘Rear Mic Boost’ for some reason? Is it all just wired up wrong?

To get the microphone to appear as an input device in Alsa and Pulseaudio I added pulse/default.pa

load-module module-alsa-source device=hw:0,0
# the line above should be somewhere before the line below
.ifexists module-udev-detect.so

Using Kubuntu; it detected and used “Smart Sound Technology Audio Controller”. Which mad the internal system mic work. How to get such drivers for Manjaro??

If the internal digital microphone array works on Kubuntu, you probably need to install pulseaudio-git from AUR

pamac build pulseaudio-git

that will replace Pulseaudio v13.0 with the development version v13.99, including bug fixes for sof-firmware
