    Can't open Linux Audio Configuration.

    So I installed Ubuntu Studio yesterday, this is my first time ever using Linux. I'm completely new to it. Usually I'm a pretty fast learner and I figure things out nicely, but this one's got me. When I try to open Linux Audio Configuration, an error pops up saying:

    "JACK can only be configured with a loaded and stopped studio. Please create a new studio or load and stop an existing one."

    The main reason I'm even worrying about getting into the Audio Config is that my Microphone isn't being detected or working on any of the sound recording software I've installed. When I try to look up help on Google, most of what I find isn't very clear or doesn't pertain to exactly what I need help with.

    So if anybody could help with either of my issues, it would be greatly appreciated. Google isn't doing it for me. Hopefully I'm posting this in the right area.

    Re: Can't open Linux Audio Configuration.

    jackd and its gui, qjackctl, are first things to deal with.

    http://en.wikipedia.org/wiki/Qjackctl

    The 4th and 8th links at the wiki will help
    with screenshots and configuration tips. Details of your
    setup will help.

    Having a constant audio source at your mic,
    will help you hear when it is connected in qjackctl.

    Press Start in qjackctl, to start jackd.
    Press 'Connect' on the lower left of the qjackctl.
    interface, in the tabbed panel that opens, in the
    Audio tab, The mic should be labeled System, on the left,
    and the soundchip will also labeled System, but on the right.
    Select each one with the mouse, then press the 'Connect' button
    on this panel, not the one on the main screen.

    There is a widget by System to click and expand the view,
    and name what is there under the hood, capture, playback,
    and other gear and software you add will also have the widget.


    some commands to use in a terminal, type one in, press enter,
    read the output. Items in brackets will be the soundchip

    cat /proc/asound/cards and

    arecord -l

    aplay -l

    aconnect -i

    aconnect -o

    these will show how linux IDs your sound chip and connections.

    There are many youtube videos showing qjackctl with
    ardour, hydrogen, zynaddsubfx, rakarrack, and in the
    sidebar lists.
    Cheers

    Re: Can't open Linux Audio Configuration.

    Some of what you said did help, and to be honest I'm not sure how to find my setup on Linux. I know the headset I'm trying to use is USB, it's a Turtle Beach X12 headset. Maybe some of what came out of the terminal will show you what you need to know to sort things out a little bit, I'm not sure what to do with all of this information...:

    Code:
    chaos@chaos-Inspiron-1545:~$ cat /proc/asound/cards 
     0 [Intel          ]: HDA-Intel - HDA Intel
                          HDA Intel at 0xf6afc000 irq 47
    chaos@chaos-Inspiron-1545:~$ arecord -l

        1 'Announce        '
    client 14: 'Midi Through' [type=kernel]
        0 'Midi Through Port-0'
    chaos@chaos-Inspiron-1545:~$ aconnect -o
    client 14: 'Midi Through' [type=kernel]
        0 'Midi Through Port-0'
    chaos@chaos-Inspiron-1545:~$
    Yet, my Sound Recorder and Audacity still aren't picking up my mic. I'm not sure what's wrong with Sound Recorder, it seems to be acting buggy right now, I really don't know. But Audacity just isn't recording anything when I hit record. I'm really lost in all this right now and I want nothing more than for it to be fixed :\

    Sorry I'm so new to this, I really hate feeling like I'm a nuisance. If there's anything you guys need me to show you from my terminal, just tell me what to type in and I'll copy/paste the results.

    EDIT:

    I changed some settings in Audacity to make it capture and playback from the right sources. Got that working. As for the Sound Recorder, I'm really not sure what's wrong with it. I'll play around with it and come back if I get any results.

    Re: Can't open Linux Audio Configuration.

    Well, so far, I've fixed all that I care to. However I still have trouble figuring out how to get Screen Recorder working. I need something that can record my screen and my system audio and maybe record my voice (if not I can use Audacity or Screen Recorder if it'll work), but other than that, I think I've done all I need to be done. Thank you for the help. If there's anything else you can recommend to me to set a new Linux user on the right path, it'll be greatly appreciated. Thanks again!

    Re: Can't open Linux Audio Configuration.

    timemachine is a good recorder app, route your final audio
    to it, and your souncard, for monitoring. The files can
    be played with vlc, and imported/edited/exported with
    audacity.

    There are many active forums, so most google queries will
    provide results. man pages are a common documentation in some
    distros, for many commands

    man lsmod

    will document using the lsmod command, regarding the
    listing of kernel modules. linux has a lot of 'shorthand'

    ls for list, mod for modules in this case of lsmod.

    http://linux.die.net/man/1/jackd

    this is an internet based man page, for jackd

    From your command output, in the brackets, is seen HDA Intel
    this is your motherboard sound chip

    Click Setup on the main qjackctl gui. The entries in the qjackctl setup panel

    Input device >
    Output device >

    (click the > widgets to see the dropdown list that contains
    what your kernel has discovered, should include HDA Intel
    or similar)
    The other one in brackets, STAC92xx Analog, can go to google,
    and many pages of topics will be there, to pick up tips,
    and become aware of the (sometimes weird) jargon.

    Glad things are working
