[SOLVED] Built-in microphone is not picked up anymore by pipewire

Since about a week my laptop's built-in microphone doesn't work anymore. It doesn't show up in pw-record

> pw-record --list-targets
Available targets ("*" denotes default): 

It seems to be recognized by alsa, though:

# dmesg

I tried downgrading from version 0.3.37 to the following versions

pipewire-1:0.3.36-1-x86_64
pipewire-media-session-1:0.3.36-1-x86_64
gst-plugin-pipewire-1:0.3.36-1-x86_64
pipewire-pulse-1:0.3.36-1-x86_64
alsa-card-profiles-1:0.3.36-1-x86_64.pkg.tar.zst 

With version 0.3.38 of those packages it's not fixed.

I also tried downgrading the kernel from 5.14.8 to 5.14.6:

linux-5.14.6.arch1-1-x86_64
linux-firmware-20210818.c46b8c3-1-any
linux-headers-5.14.6.arch1-1-x86_64

I also used alsa-info.sh script for more debug info. I also have the script's output from before it happened:
Good: http://alsa-project.org/db/?f=869dbc954 … 20a7a5d963
Bad: http://alsa-project.org/db/?f=08c306cd5 … 3666e7eda7

I'm using default configurations for pulseaudio and pipewire

The selected profile is wrong, check the configuration tab in pavucontrol or run

pactl set-card-profile alsa_card.pci-0000_00_1f.3 output:analog-stereo+input:analog-stereo

Re: [SOLVED] Built-in microphone is not picked up anymore by pipewire

Thank you, that works! In pavucontrol it was called "Analog stereo duplex", which didn't seem to me like anything with a mircrophone. Is it just that I'm not a native speaker or is that an incorrect name? I would expect it to be called: "Analog Stereo Output + Analog mono input" or something.

"duplex" bascially means both directions at the same time:
