Well it's not too surprising. The internal microphone is connected to
the "MIC1" control. And the external too. Whenever I plug something into
the external microphone jack, the internal one gets automatically muted.

The Line In jack is connected to LINE1 control.

Master volume seems to be controlled by LOUT1 control. By muting this, i
get absolute silence.

And the last thing i've found so far is that PCM channel is the one that
Totem media player uses to play its sound. Also, it's used by Sound
Juicer to play the CD. I wonder though - why isn't a Mute control
available for it?

That's what I tried yesterday. Switched all controls to Line Out. That's
how I found out what Mic and Line In jacks are connected to. Now these
two are set to Mic and Line In types, respectively. And everything else
is Line Out. Nothing... Same happens when everything else is set to
Headphones.

Btw, when I redirect the output to Line In, and make everything else
(HP-OUT, LINE-OUT, LINE2 and MIC2) be "Headphone" pins, I get a lot of noise 
from the speakers connected to the Line In jack. These seem to catch
some interference even from the video card (just noticed). That
electronic noise differs depending on what I see in the screen atm. Weird...

Maybe. I just though that maybe it doesn't really mute all the sound,
but just some pins?

I'm almost out of any ideas. :/ Could it be that the notebook uses
digital i/o for its internal speakers/heaphone jack or something like
this?
