Built-in Microphone not working on Lenovo Ideapad 5 (Kernel 5.9.8)

I just installed Arch and my laptop's built-in Mic isn't being picked up. My card is

HDA Intel PCH

or

SND_HDA_INTEL

. Heres the output for

journalctl | grep sof-audio-pci

Dmesg shows input:

HDA Intel PCH Mic as /devices/pci0000:00/0000:00:1f.3/sound/card0/input28

So my card is being recognized, but pavucontrol isn't showing it nor alsamixer.

Here is the result of

arecord --list-devices
**** List of CAPTURE Hardware Devices **** card 0: PCH [HDA Intel PCH], device 0: ALC257 Analog [ALC257 Analog]   Subdevices: 1/1   Subdevice #0: subdevice #0

Here is the full

lsmod

output: https://pastebin.com/w1tusmef



Here is the full

dmesg

output: https://pastebin.com/Hw0WcvyE



I've been searching for days, any help is appreciated.

Re: Built-in Microphone not working on Lenovo Ideapad 5 (Kernel 5.9.8)

A quick search showed that the deprecated

snd_hda_intel.dmic_detect=0

option, existing in your kernel commandline (dmesg), should have been placed at "/etc/modprobe.d".
Use the new

options snd-intel-dspcfg dsp_driver=1

option, instead.
Furthermore, the

options snd-hda-intel power_save=0

option could be used to disable automatic powersaving kicking in.
Also, try installing the "alsa-firmware" package and see if it helps any.

Re: Built-in Microphone not working on Lenovo Ideapad 5 (Kernel 5.9.8)

install sof-firmware and alsa-ucm-conf remove the modprobe/kernel commandline config both intel,dmic-detect and the relevant equivalent dspcfg setting are expected and known to break the mic.
