Hello,

I recently installed FreeBSD on my laptop (X1 Carbon 4th gen). The hardware
support is not terrible, but I am having issues higher up in the stack. One
of the problems I've encountered is that I cannot get my microphone working
in Firefox, even though it works in native applications and in Chromium.

"Doesn't work" means that:
- Firefox thinks I have a "default" microphone and asks for permission when
I try to use it.
- Websites that test microphone by recording and playing it back either get
silence or complain about being unable to find the microphone.
- https://test.webrtc.org/ reports:
  Audio capture
  [ OK ] Audio track created using device=default
  [ FAILED ] No active input channels detected. Microphone is most likely
muted or broken, please check if muted in the sound settings or physically
on the device. Then rerun the test.
- It works in Chromium: I can hear myself when I record and re-play on a
mic testing website.
- I do not have PulseAudio installed and I believe my Firefox is using Alsa
emulation.
- As Chromium seems to be compiled without PulseAudio, I tried recompiling
Firefox with PULSEAUDIO: off. No change.
- This is probably useless, but: My webcam works in Firefox.
