Update: I went through some of the code and started to replace some of
the lines that caused errors with the latest alsa-driver git blobs.
These fixed some of the errors, but not all of them. However, after
giving up, installing pulseaudio, giving up on that, rebooting a few
times, updating a few times, giving up on that, and then forgetting
about it, the microphone magically started working.
