21:09:31.650 JACK is starting...
21:09:31.650 /usr/bin/jackd -R -dalsa -dhw:0 -r48000 -p1024 -n2

But the program (Pure Data) where I need it for gives this error:
Code:
audio I/O error history:
seconds ago	error type
     3.39	A/D/A sync
     8.15	unknown
    19.46	A/D/A sync
    41.26	A/D/A sync
    46.98	A/D/A sync
    55.71	A/D/A sync
    60.68	A/D/A sync
    60.69	unknown
    80.14	unknown
    80.14	unknown
error: JACK error: zombified - calling shutdown handler
Probably something wrong with Pure Data, so I will also post it on that form. Thanks for the help.
