>When you say "shows input", do you mean that the microphone shows activity on the "Input Devices" tab, or that there's a stream for chrome visible on the "Recording" tab? Both. Mic shows activity on "input Devices" tab, and Chrome appears as a stream on "Recording" tab. By the way, Chrome also appears as a stream on "Playback" tab. Both streams dissapear if I close Chrome. >The earlier pulseaudio log didn't show any recording streams from chrome. If you manage to get chrome to create a recording stream (you'll see it in the "Recording" tab of pavucontrol), a new log might show something, although I'm not particularly optimistic about that. Funny. As I told you, saw a stream in pavucontrol "input Devices" tab while running Chorme with no logging, but now that am logging, no recording stream appears. And BigBlueButton gives no cracking echo for my voice, as a matter of fact no echo at all. Pure silence. You will find new log as an attachment. >To narrow down the problem further, you could try recording from the microphone at the same time when chrome is supposed to be recording from it. You can use this command: parecord --device=alsa_input.pci-0000_00_1b.0.analog-stereo test.wav When you play back that test.wav file, does it contain better microphone audio than what chrome produces? Not better at all. It contains the same cracking noise that chrome produces. Maybe even worst, because the signal (cracking voice noise) to noise (ambient noise) ratio appears worst than the signal-to-noise ratio from "live experience" (while running Chrome). Thank you very much for your help. 2017-02-16 21:15 GMT-03:00 Fatima Castiglione Maldonado å?? < castiglionemaldonado at gmail.com>: > >When you say "shows input", do you mean that the microphone shows > activity on the "Input Devices" tab, or that there's a stream for > chrome visible on the "Recording" tab? > > Both.
