Hi,
I made a few more tests, with a other usb sound card (behringer UCA202), and
I did not have any problem with rosegarden. But I still have some issues
with Pure data :(
I also tried the last patch from Adam Sampson, on my 2.6.26.3-rt3 kernel but
without any success.
I think, but I am not sure that this is an alsa-driver issue (usb-caiaq
module)
Perhaps we could directly contact the main developper of this module :
Daniel Mack daniel at caiaq.org
Cheers,

I would like to understand if it is a JACK or a driver
issue. It is
obviously not a Rosegarden problem.
I have the same problem if I run jackd with -Xseq option ("MIDI driver:
seq" in qjackctl). It starts normally, but if I try to shut it down the
process jackd enters in an " Uninterruptible sleep" state (waiting for IO?)
and I cannot kill it:
$ ps -eo pid,cmd,state | grep jackd
7997 [jackd] D
8836 grep jackd R
I posted this issue to the alsa-devel and jack-devel mailing lists too, but
no one answered me.
I will let you know any progress.
Cheers,
Marco

Well, I just tried rosegarden, and I have the
same issue : qjackctl crash,
and dmesg command output the same as you.
After that, If I try to run qjackctl again, it fails, or some times it
runs, but if I play some notes on Zynadd for exemple, the sound is totally
crappy. I have to reboot the system to solve this problem.
grrrrr

Hi,
I do not have your answer. But I just bought an Audio Kontrol1 few weeks
ago, and I got similar issues, when I run puredata. and well I thinks this
is a midi related problem. But I actually don't know if this is a kernel,
Jack, alsa or others softwares issue.
I will make more tests in the next days and will tell you.
But, if any other people have any experience about this sound Card, I
would be happy to read about It.
Cheers,
Mysth-R

Hi,
it's about one year that I'm using my Native Instruments Audio Kontrol 1
(USB2 audio/MIDI interface) only with audio applications and it has been
working well so far.
Now I'm trying to use it with Rosegarden (MIDI) and, as soon as I start
Rosegarden, JACK crashes, the process jackd becomes "uninterruptible" and
with the command dmesg I find the following new lines

I already asked to the Rosegarden and JACK people, but they couldn't
help me: it seems to be a driver related problem, as I can happily use
Rosegarden if I run JACK with the internal Intel sound card.
The program versions I'm using are: jackd 0.116.1, rosegarden 1.7.2.
Here's some other outputs:

I do not include the jackd and rosegarden outputs becouse they are quite
long, but, if you think they are useful to understand what is going on, I
can send them too.
Any ideas?
Thank you
Marco
