Here is a list of platforms who's microphones won't work on OpenBSD:
https://thesofproject.github.io/latest/platforms/index.html#supported-platforms

Microphones in many modern Laptops don't work. Thanks to intel smart sound technology (Intel SST),
microphones now need a firmware (https://github.com/thesofproject/sof) and nobody has written a
driver for OpenBSD yet.

You can use a headset on the headset port and the microphone there should work. It's only the
builtin mic that won't do anything (even though all toggles in mixerctl / sndioctl appear operational).

Fun part reg SOF: it doesn't build with clang, see FAQ:
https://thesofproject.github.io/latest/introduction/index.html

So - I don't think we'll see mic support for these platforms anytime soon.
