Yes, I see;

I tried the above already (following a hint) and as well
in device.hints(4); the result is, that /dev/dsp1 disappears, as well
/dev/mixer1; and in /dev/mixer0 there is another recording source
Mixer vol is currently set to 93:93
Mixer pcm is currently set to 88:88
Mixer mic is currently set to 70:70
Mixer mix is currently set to 81:81
Mixer rec is currently set to 70:70
Mixer igain is currently set to 78:78
Mixer ogain is currently set to 65:65
Mixer monitor is currently set to 74:74
Recording source: mix, monitor
but the internal mic does not record (even if jack is unpluged), only
jack records (if pluged, of course);
if I set
# mixer =rec monitor
Recording source: monitor
the jack as well stops recording;

will try now sequence number "15"...
