The mic works ok. However, we use tools for work such as hangouts and bigbluebutton for teleconferencing and there, the microphone still doesn't works. The web apps can access che mic, but no sound is coming out of them. I can see some activity on the sound cards related to the mic, but no volume adjusting solves the problem. kern.audio.record is properl set to 1. I made some attempts with various mixerctl settings, but nothing changes. I confirm is bot an hardware problem, it seems it's related to how firefox handle the sndio back-end for hangouts et simila. -- Andrea
