Thanks for your answer.

I have now uninstalled the dev package, because I thought maybe this was the
problem ...

The problem is the computer is fixed with no network... :(

Now I copied some more infos:

If I start jackd with 0 out/in: kein Fehler; output in SuperCollider is
working z.b., but the input sound is totally destorted ...

if I start jack with 4 in/out:
loading driver ..
apparent rate = 44100
creating alsa driver ... hw:0|hw:0|1024|2|44100|4|4|nomon|swmeter|-|32bit
control device hw:0
configuring for 44100Hz, period = 1024 frames, buffer = 2 periods
ALSA: cannot set channel count to 4 for capture
ALSA: cannot configure capture channel
cannot load driver module alsa
19:06:31.001 JACK was stopped successfully.
19:06:33.000 Could not connect to JACK server as client.
(I have also tried differenty channels, periods, buffer-size, etc.)

in PD only:
/dev/dsp (writeonly): Device or resource busy
/dev/dsp (readonly): Device or resource busy

> How do other jack applications work ?
as mentioned supercollider works, but not the input. (but I'm not sure if
this is a problem with jack ...)
