    edirol ua25 set up audio in/out

    Hello,
    i'm trying to set up edirol UA25 to play guitar with Rakarrack on ubuntu 12.04
    in the set up window of qjackctrl I selected (I think so) the correct options: i've seen a correct one in the forum
    in the audio set up of linux I choose UA25 for in and out

    but

    in the connection window of Qjackctrl I can't see UA25, but only system and rakarack for in and out
    in the system input ther are two mycrophone icons

    the problem is that rackarack captures the audio, not from edirol in, but from pc mic.
    and the same is for the output., it comes from pc speaker.

    I tryed to change usb port to connect edirol, but nothing changed

    any idea?
    thanks

    Give
    Code:
    aplay -l
    You didn't select right card for JACK. It will always be "system" in qjackctl, thats just how JACK names audio ports from soundcards.

    Before starting jack, make sure to choose the correct device. You do this from: Qjackctl -> Setup -> Interface.

    By choosing the right audio device, I meant choosing the right audio card, in your case the Edirol UA25.

    Once you have chosen the correct device, just start jack.

    Yes, hw1 should be your device. No need to define input device, leave it on default. Just choose interface.

    Re: edirol ua25 set up audio in/out

    Ah, yes. I missed this. Do not set input and output separately - set those to "default".
    Just use "interface" for choosing your card.
