Microphone stopped working (possibly after installing pipewire)

I noticed today the mic for my Logitech PRO X SE headset wasn't showing up in discord, nor does it show up in Plasma system settings or under pavucontrol.  I recently installed pipewire, so that may have been what caused it. It shows up as card 0 under /dev/snd/by-id:

Re: Microphone stopped working (possibly after installing pipewire)

Fixed it!  Under pavucontrol in Configuration, my headset was set to "Analog Stereo Output".  Setting it to "Analog Stereo Output + Mono Input" made the mic appear again and it's working.
