</span>When you say "shows input", do you mean that the microphone shows<br>
activity on the "Input Devices" tab, or that there's a stream for<br>
chrome visible on the "Recording" tab?<br>
<br>
The earlier pulseaudio log didn't show any recording streams from<br>
chrome. If you manage to get chrome to create a recording stream<br>
(you'll see it in the "Recording" tab of pavucontrol), a new log might<br>
show something, although I'm not particularly optimistic about that.<br>
<br>
To narrow down the problem further, you could try recording from the<br>
microphone at the same time when chrome is supposed to be recording<br>
from it. You can use this command:<br>
<br>
parecord --device=alsa_input.pci-0000_0<wbr>0_1b.0.analog-stereo test.wav<br>
<br>
When you play back that test.wav file, does it contain better<br>
microphone audio than what chrome produces?<br>
