    MusE can't connect to jack server

    I am using Natty Narwhal. After installing the MusE package, I installed jackd1 (removing jackd2 in the process) because with jackd2, MusE would refuse to start up at all (it would just show me this little box telling me that it can't connect to jack and then commit seppuku). Now it does start, but it still can't connect to jack. Though I gotta admit I am new to MusE as well as to jack, so I may very well be doing something very wrong. New as in, I know about either since roughly an hour in which I've been trying to get the two to work together. Basically, all I know about jack is that it's some sort of audio daemon that MusE needs.

    Re: MusE can't connect to jack server

    Nvm - I actually just reinstalled QJackCtl (I removed it after it seemingly didn't work with jackd1 for some reason), and it actually works just fine now. Well, I wouldn't say fine, but at least it doesn't give me any errors right now.

    EDIT: Yeah, saying that it works was maybe a bit exaggerated. Now muse doesn't complain anymore, but in exchange the moment I start jack, no sounds work anymore (no system sounds from Ubuntu, no sounds from flashplayer, nothing). So uh... that's... pretty bad, no? If someone knew how to fix that/how to find out what's wrong and THEN fix that, I would really appreciate that. (Everything goes back to normal only if I stop the server AND exit QJackCtl - pretty weird, I'd have thought stopping the server would be enough).

    allo HKei!

    so... you can't read and search?

    the 10th treads bellow yours...

    anyway,

    the moment I start jack, no sounds work anymore (no system sounds from Ubuntu, no sounds from flashplayer, nothing). So uh... that's... pretty bad, no?
    everything's fine and work as expected!

    just follow this: http://ubuntuforums.org/showthread.p...5#post11176545

    Re: MusE can't connect to jack server

    I searched for the muse thing, and I searched stuff about jack too, but I didn't know anything about PulseAudio. It's not like that kind of information is just shoved into your brain the moment you install Ubuntu :O

    Now the sound output works again, but MusE doesn't work anymore...

    allo again HKei!

    I won't judge you in any way, I was just passing a comment!

    welcome to the community!

    we all pass by the same road, learning! it's a good thing!

    unfortunately I can't help with Muse! I'm not familiar with it 'cause I dont use it!

    someone will pass by and help you, be patient!
