JACK support is dodgy

[Toby Smithe]

Binary package hint: mscore

Taken from https://bugs.launchpad.net/ubuntu/+source/mscore/+bug/207565/comments/7:

thanks for updating the script!
On the surface it works fine/as advertised, however:
$ mscore.real
Couldn't resolve property: 2

$ mscore
/usr/bin/mscore: 28: list: not found
Using JACK for audio
Couldn't resolve property: 2
JACK ERROR: cannot complete execution of the processing graph (Resource temporarily unavailable)
JACK ERROR: zombified - calling shutdown handler
JACK SHUTDOWN

(jackd didnt shut-down, it shutdown the mscore socket)

Now I have no idea why this happens. Like I said, mscore runs fine.

thanks

I have sent an e-mail upstream to ask about this. Please see

http://sourceforge.net/mailarchive/forum.php?thread_name=2d14528f0803311346i4be080b1if22ee3714a8dce8f%40mail.gmail.com&forum_name=mscore-developer

Copying from the e-mail on the upstream list:

No idea. There is too little information. Does JACK work with other
applications?. How is JACK configured (buffer size)? What soundcard?
Some soundcards/chips/drivers are just crap and do funny things after
an underrun so i would suggest trying other frames/period or periods/buffer
settings.

Having not heard back, I'm closing this bug. Please ensure that your JACK settings are optimal before re-opening the bug, thank you.
