I have verified PulseAudio and everything seems to be working fine.

Using pavucontrol shows all inputs work fine and input monitoring bars
jump when talking.

Still Firefox 94.0_2,2 does not record any sounds from any sound input
even though inputs are listed.

Quick fix is to switch FF backed to OSS there mic works fine:

about:config / media.cubeb.backend = oss
