Good time of the day, Camaleón.
Thank You for Your time and answer, again.

May this is the reason?

Probably, says about connector only?

May one for modem, another - sound card?

Actually, I never saw it. :o) - Only on desktops - w/o any problems.

Hmm. On desktops I see exactly word microphone or mic - do not remember
correctly. Then alsa mixer has appropriate handle w/ which I can change
its gain. - Here, on laptop, I miss all this.
> How are you testing your microphone?
Eventually, knocking on microphone gives no any sound in speakers.
Whereas on desktops - it does.
The microphone is working - tested on desktops.

Done, restarted w/
# /etc/init.d/alsa-utils restart
correct? - But nothing.

OK, thank You! :o) - It inspired me!

Wow! Great spirit! Thank You for Your help! - No matter what will be
