The -fn
argument is'nt the best choice to use jack_capture, better use
it like that:
jack_capture --channels 2 --port system:playback* output.wav
Thanks for the sugestion, but it doesn't seem to
help. jack_capture
doesn't crash, doesn't create output.wav, just sleeps (strace doesn't
show much activity after the initial setup) until killed.
Seems like your jack isn't working properly, but in case
not I would be very interested in getting it fixed.
Which version of jack are you using?
jackd --version
In case you are using 109, it would be a good idea to up- or down-grade
immediately.

This is exactly the same as just writing "jack_capture". :-)
Also, can you post the console output from jack_capture when you run it?
And what does strace say? Thanks.

jackd version 0.116.1 tmpdir /dev/shm protocol 24
Also, can you post the console output from
jack_capture when you run it?
It doesn't produce any visible output.
And what does strace say? Thanks.
I put it here: http://www.math.bme.hu/~asimon/jcstrace.tgz
It's the result of
strace -o strace -f -ff ./jack_capture
Thanks for looking at it!

Can you try this one:
http://heim.ifi.uio.no/~ksvalast/jack_capture.c.gz
?
I've just added lots of "fprintf(stderr,"<n>");" during
init.
I wonder where things stop.
Hmm, this doesn't tell me anything. Seems like it only
try to start jack, but I'm not sure.

Andras Simon:
That's just buffer init. Weird! Perhaps you
are running out of memory? Can you try
./jack_capture -B 0.1
?
Also, what machine do you have? (/proc/cpu) There's some atomic
operations going on in the buffer init, maybe they are locking up.
