    I need help for config & using Ardour with audio please

    Hi everybody,
    I'm new user and I was working on macintosh with logig audio.
    I'm musician, not informatician, and it seams to be difficult to set the configuration in midi and audio.

    I got en EDIROL UA-20 that seams to be recognize on the system.
    Code:
    cat /proc/asound/cards
    0 [NVidia         ]: HDA-Intel - HDA NVidia
                          HDA NVidia at 0xdbef8000 irq 22
     1 [UA20           ]: USB-Audio - UA-20
                          EDIROL UA-20 at usb-0000:00:02.0-1, full speed
    Code:
    cat /proc/asound/modules
     0 snd_hda_intel
     1 snd_usb_audio
    Code:
    aplay -l

      Sous-périphériques: 0/1
      Sous-périphérique #0: subdevice #0
    When I try to test the audio input&output with Audacity it works like it :
    (JackCtl is stopped) , I choose ALSA, output UA20 UsbAudio hw1 & input UA20 UsbAudio line0 hw1
    Then I can play and record sounds incoming the UA20
    Happy !

    Now when I want to do the same with Ardour, I choose in the menu "Audio/midi setup"
    System : Jack
    Pilote : ALSA
    Device : UA20
    But there's no sound even if I start JackCtl
    I can see the view-meters in Ardour but there's no sound coming out the UA20

    Do I miss anything ?
    Someone could help me ?

    You're probably missing making all the relevant connections. I'd recommend avoiding letting Ardour start up JACK for you; that limits what you can do.

    So, configure JACK using QJackCTL - since this is a USB soundcard, you'll need to specify a value of 3 for Periods/Buffer. If you're wanting MIDI as-well, then select the ALSA Sequencer in QJackCTL. Once you get JACK started with QJackCTL, and not throwing lots of XRuns, start Patchage. This is your digital Patchbay, and you'll see all the available connections in there.

    That's the point at which you start Ardour. Personally, I go through the more-detailed settings in there and uncheck all the options for automatic connections (I do have 300W RMS per-channel hooked up to an Edirol DA2496... A feedback loop upsets the neighbours streets away).

    Coming from a Mac background, you might-well find KXStudio a little easier to get going. I find the session management and whatnot a little lacking in Ubuntu Studio - but I prefer its desktop to the KDE one in KXStudio and hack the pair into an unholy alliance.
