    [12.04] jackd not working, ubuntu

    Hello,
    im quite a new user to ubuntu and I have some problems that I'd appreciate any help for.

    I'm trying to make audio work in rosegarden, and therefor installed jackd and qjackctll. That however does of course not just work on its own! However, after reading and searching a bit I'm still confused to exactly what these applications do or how they're supposed to be managed.

    I tried method 1 solution from this post, without installing ubuntu studio, but it didn't do any difference.

    This error text is produced in qjackctl when trying to start:
    Code:
    Cannot connect to server socket err = No such file or directory
    Cannot connect to server request channel
    jack server is not running or cannot be started
    12:16:33.408 ALSA connection graph change.

    Does it give anyone any idea?

    EDIT: are the correct interface, input device and output device selected in qjackctl? if you have one sound card (default) should work.

    The first thing you should do is start qjackctl, press the triangle style "start" button to start the jack server.

    Did jack start correctly? ok, after this open up rosegarden. Now go back to qjackctl and open the "connect" window and see if Rosegarden shows up at all. The next steps depend on how you want to use Rosegarden.

    If you DON'T see rosegarden in the "connect" window then go into rosegardens settings and see if there is an option for where to route input/ output. It should be sending output to Jack (there may be 2 jack options), or ALSA.

    Thx for your reply AstroLlama, but now it seems to be magically working for some reason!

    I guess the install from the other repositories needed a reboot.

    Over. out. and.
