    AUDIO: Youtube/Audacious output disappears after starting Ardour or Qtractor

    Hi all, I'm just trying to get familiar with Ubuntu Studio in the hope of contributing something to the project, but even the basics are giving me a headache at the moment!

    Here's the scenario: I find a YouTube video on an audio app I want to learn (Ardour, Qtractor, etc), then start the app, and find that audio on the YouTube video has stopped working. However, if I leave the video playing, and start the app, I get an error message. Here's the error message Qtractor gives me:
    "The audio/MIDI engine could not be started. Make sure the JACK audio server (jackd) and/or the ALSA Sequencer kernel module (snd-seq-midi) are up and running and then restart the session."
    Once I get audio working in Ardour or Qtractor, I then can't hear any in video (online or native files) or listen to ogg/mp3s via Audacious.

    I've tried searching for a solution but the closest I got was this, and a solution isn't really offered:
    http://ubuntuforums.org/showthread.php?t=2118762

    I also found this thread;
    http://ubuntuforums.org/showthread.php?t=1418391
    ...but the solutions offered make me nervous, as there is not mention of the type of specialist audio software used in Ubuntu Studio. I'm worried that reinstalling pulseaudio/libasound2 and/or hacking audio conf files will only end badly for Ardour/Qtractor and the other apps I have installed such as Renoise and energyXT. Audio on Linux seems a bit of a minefield right now, takes me back to the bad old days of pro-audio on Windows (yes, there is such a thing!). I want to get to grips with this and understand how the bits of the jigsaw all fit together. Maybe then there's a slim chance that one day I'll actually be able to contribute something back...

    I'm running Ubuntu Studio 12.10 64bit on a Toshiba P850-321 using onboard Realtek ALC280Q-GR audio hardware (I haven't even started trying to get this lot working with my UCA202 yet!!).

    Any help and guidance with this very gratefully received!!

    Hi,

    Not sure if the pages on Ubuntu Studio in the NewDocs link in my signature will be of any help.

    Cheers -

    Thanks BlinkinCat! I'm just having a look now (my handicap being that I probably don't know the right terms to search by). Looks like a fantastic resource anyway, though - I've bookmarked and will be working my way through the docs....

    Wow, there's a lot of info in those docs, BlinkingCat! OK, can't spend any more hours on this tonight, need to sleep and get up for work tomorrow... will have to try to pick this up again as and when I get chance, hopefully this week. Sigh - ah well... every time I think I might be about to start understanding how audio works on Linux, I just end up realising the ever-increasing enormity of the task.

    You don't know how pleased I am that NewDocs has been of benefit to you,

    Hope you get it all sorted out.

    Understand that Ubuntu Studio is for production work and if you are trying to produce a sound track using Ardour and watch a video at the same time--that will be problematic. It's not that you can't do it, it's just that the Studio setup is not designed for that use case. It would be better to have a laptop playing the tutorial that you want to watch and have the desktop running Studio with the application that you want to learn. Because of the real-time nature of sound editing, you can't have two sound apps running at the same time. (You can, but you may not get sound out of one of them.)

    Of course, you will quickly discover this after reading a few pages of NewDocs.

    Download video and play it in JACK aware video player. (e.g. VLC)

    Hi tgalati, thanks for your response. I do fully understand the purpose of Ubuntu Studio (I installed it because I recognise its advantages and potential), but the simple fact is that watching a video online whilst running pro audio software is something that 'creative humans' can do in both Windows and OSX. I've managed to move the rest of my work and play into Linux 100%, the only area where I can't quite replicate my workflow yet is in audio production - that's why I want to get involved in the Ubuntu Studio project. It's a fantastic distro and I do genuinely love it, but much as it pains me to say so, I don't yet feel that it's a credible alternative to using Windows or Mac for most pro audio tasks. (I don't think it's that far off though, and it's catching up fast!) I'm aware of some who are managing just fine though, of course.

    The desktop/laptop combo is one I've considered, but not possible right now as I'm 'confined to quarters' recovering from surgery, so I'm limited to laptop only. Even so, it's a workaround rather than a solution - I'd like to see (and when my skills have improved, hopefully contribute towards) a forward-looking solution that enables pro audio and std audio to get along. There are any number of scenarios where this would be of benefit. I produced library and commissioned audio, and to replicate my Windows workflow I need to be able to quickly learn how to use new and unfamiliar tools on the fly, with online video tutorials aften being an ideal means of doing so. I then close down YouTube and get down to the real work.

    To take it to extremes, imagine Ophir Kutiel (Kutiman) attempting to produce the ThruYou series using the tools available in Ubuntu Studio, or any other Linux distro. Possible? Certainly, but the workflow would undoubtably be haphazard and frustrating. Please, please understand that I'm not slating Ubuntu Studio, I'm a huge fan and an advocate, even after a relatively short time using it. However, I do feel I need to point out that being able to replicate a task that other operating systems can handle without much difficulty may be advantageous in Ubuntu Studio/Dream Studio/any other Linux distro as well - to the audio pro as much as the amateur/beginner. Just food for thought...

    Maybe I'm also the fool who doesn't accept a situation as it currently is, and wants to strive for a better way It doesn't exactly make for an easy life, I know!

    Nice solution - I hadn't even thought of that. Thanks jejeman!

    UPDATE: I'm really finding this feature very useful, for Ubuntu Studio and for my vanilla Ubuntu installation too (I have Ubuntu 12.04 installed alongside multibooting with Win7 as an environment to learn about development/programming languages, bash etc, and tinker under the Ubuntu hood without risk of stuffing up my Ubuntu Studio installation). Thanks for this, it makes the wiki a lot easier to navigate - great work.
