Hello Felipe,
Thanks for your answer. I'm currently using pavucontrol, as soon as I disable
one channel from the microphone (for example the left chanel level is 0%), the
microphone will work normally. I've found on the Ubuntu an issue that looks
similar to the one I've noticed with this laptop (
https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1002978 ). Maybe the
problem is specific to this type of microphone ?
Best Regards,
Florent Mazzone

What happens if you use pavucontrol to control the microphone volume?
Could you attach the output of `pactl list sources` both when the
volume is low and after the volume is up? Also, a verbose log[1] of
the problem occurring may be useful.
