Felipe,
I set "Element mic boost" "volume" to "zero" instead of "0" and it works : I can increase the input volume level up to 153%.
The link resulting from alsa-info.sh script :

OK, we can report this as a kernel bug then.

Did you try setting zero instead of 0 (that is, putting the word
'zero', not the number)? That is what i saw elsewhere as a workaround
for this. Also try setting it to 'off' and 'ignore'. Note that these
are workarounds, so hopefully this can be fixed in the kernel.
Dear kernel maintainers, I'm forwarding this bug to you: Jean reports
that when the Mic Boost control is set to a value > 0, it introduces
distortions.
Jean, please run the alsa-info.sh script as documented here[1]. The
kernel maintainers will probably need this.
