Newb question - can't connect to JACK.

[StaggerLee]

I have successfully set up JSampler and it works fine when ALSA is selected as the audio output, but I would like to route it into Ardour via JACK and whenever I attempt to set the output to JACK I get a "broken pipe" error. I'm guessing this has something to do with my audio configuration but I can't figure it out. Do I need to change Jack's settings somehow to allow this to work? Any help is appreciated!

Hi StaggerLee,
A little more information about your system will be helpful. Which distribution of Linux are you running (and which version), plus which version of jack are you using? Which version of LinuxSampler are you using (i.e did you download the Debian DEBs or did you compile from the CVS code?). And is jackd running when you try to connect?

Thanks ggoodesa, I'm using Ubuntu Hardy 8.04 with jackd 0.116.2 and qjackctl 0.3.4. Linuxsampler is 0.5.1 (Ithink I just downloaded the deb's - can't remember for sure). Jackd is running, here is the ouput of my terminal when I try to create an audio out to jack, maybe this will help:

StaggerLee,
the 5.1 version is quite old now compared to the work that's been done since then. You would be better served installing LinuxSampler from source, via CVS, the urls for which can be found on the downloads page of the website. The broken pipe issue was fixed in later builds.

Alex.

p.s. If you go down this route, ensure you've removed all the previous stuff first.

I finally found the time to revisit this problem from a few months ago, I removed all the existing packages and installed everything from source. I ended up getting the same "segmentation fault" error and tried uninstalling everything and downloading all the new Hardy debs - still no luck. Please help! Here's the output of my terminal:
