Thank you. The result of this is:

1)
mixer(1) is now showing a line 'monitor' in addition and as recording source:

# mixer
Mixer vol      is currently set to  83:83
Mixer pcm      is currently set to  78:78
Mixer mic      is currently set to  87:87
Mixer mix      is currently set to  81:81
Mixer rec      is currently set to  65:65
Mixer igain    is currently set to  78:78
Mixer ogain    is currently set to  65:65
Mixer monitor  is currently set to  87:87
Recording source: mix, monitor

2)
in Skype I can only choos between /dev/dsp and /dev/dsp0 and /dev/mixer1
does not exist anymore;

3)
recording still works only from jack, not from build-in mic;

4)
if I set 'mixer =rec monitor' it does not even record from the jack;

I even checked the BIOS if there is something to disable the mic, but it
isn't.

Thanks for your help in any case. Btw: If this does matter, it is with
kernel r214444.
