As you requested:
    $ cat ~/.jackdrc 
    /usr/bin/jackd -v -P20 -dalsa -dhw:0 -r48000 -p1024 -n2 -Xseq
I tried a few other combinations but it just doesn't work.

I see the line
    Jack: jack_client_open PortAudio
in the program output about 20 lines before it shuts jack. This is a similar
symptom I observed when I built fluidsynth with portaudio support (Lots of
XRUNS leading jackd to shutdown or crash after 2-3 seconds). For this reason,
we disabled the fluidsynth's portaudio support in the Fedora package. Over the
time I saw a couple other people from other distros report the same issue.

Similarly, I disabled the portaudio support of jackbeat. There is no very easy
way to do it. I hacked on the source. After that, I compiled and, guess what,
jackbeat works properly. This is really strange. With the unhacked jackbeat,
even when I use the -c Jack option, it still tries to interact with portaudio.
I wonder why this happens.

I understand that you don't want this package to be in Fedora yet. Maybe you
can ask upstream to make portaudio and pulseaudio support optional for this
software, and then we can compile it for jack only.


Otherwise the package is in perfect condition, normally I would just go ahead
and sponsor you. :(

Let me know when you submit another package. I will be busy for the next couple
months, but I will definitely make some time. And I appreciate your offer for
helping with Audio production packages. I really need it.
