>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.
