No audio input in firefox on ALSA

[uis246]

Audio playback works fine, as in I can watch videos without major issues, but audio capture does not work. All websites for testing microphone show silence.

One of potential clues is alsa_enumerate_devices, where channel count and samplerate are obtained for playback, while filling out device structure for recording(CUBEB_DEVICE_TYPE_INPUT).

WASAPI backend input enumeration writes number of channels of capture device instead of playback.
