Ubuntu Multimedia :: Failed To Connect To JACK Audio Server?

Jun 24, 2010

Im a composer and I loaded up on some excellent applications for music creation and notation- so excited..
I start with Rosegarden. Failed to connect to JACK audio server. Try my other applications, same problem.
Basically the JACK audio server just WILL NOT RUN (correctly). I can sudo it and press start, but still it wont "play with" the applications! Heres the error message from JACK (I also get related errors when I try to do ANYTHING involving music creation):

error JACK Audio Connection Kit
-overall operation failed
-unable to connect to server
Here is the "fatal error" from MusE
"Failed to Find Jack Audio Server"
This is the JACK output:

Ubuntu Multimedia :: Jack And "Muse Failed To Find A Jack Audio Server"

Jun 27, 2011

I've got an Acer Aspire 5101 with Natty on it and everything works so far, but I can't start Muse. It says: "Muse failed to find a jack audio server". At the bottom it also says: "...if Jack was started check if it was started as the same user as Muse". This might be the issue. But how can I check this? BTW: Jackd has been installed and I am a Member of the Audio Group.

I am new to Ubuntu and don't know how to fix this. I got this Notebook for free, because my Brother wanted to dispose it as it didn't worked properly after he reinstalled xp. Only the dvd-drive is broken, the rest is in really good condition for such an old thing. After a lot of trial and error I could finally install Natty from USB.

Ubuntu Multimedia :: Jack Can't Connect To Audio Server?

Nov 21, 2010

I try it for the first time. Befor I changed to linux I used MS Windows 7. There I worked much with SonyVegas for video and Adobe Auditon for music. Yesterday I searched for alternatives under Linux for Audition. And I found much. The screen shots says, that they look similar to Auditon. I downloaded them and installed them. But they doesn't work. One of them say they can't connect to Jack. Some of them say nothing, and so they don't record my line in/microphone input. After a few seconds I of search, I knew that all of these programs uses jack for Audio. I installed it, but the situation wasn't better. Then I found a wiki, and try that: first start jack, than start the program. So I do. But there i get a few error messages: At first I should copy to lines to the file lines.conf. I do it. Then I should be member of the audio group. I do that.

Ubuntu Multimedia :: Forward Audio To Windows Using JACK

Nov 1, 2010

Does anyone have any experience of forwarding audio from Ubuntu to Windows 7 x64 via JACK? I'm struggling to find any useful documentation. I've tried to accomplish the same using a Pulseaudio server, which is better documented but the windows binaries are years old and as far as I can tell can't be made to work without disabling IPv6. Any other ways to forward audio would also be welcome. Bandwidth isn't really an issue as it's VM to VM on the same machine.

Ubuntu Multimedia :: Jack Stops All Audio For The Duration Of Its Run

Mar 9, 2011

I have had no problems whatsoever with audio in ubuntu 10.10. Both input and output have worked great, but alas now there's a problem.

I recently installed ardour2 with jack (using apt-get) but for some reason, anytime I start ardour2 (which starts jack implicitly) all audio stops on the whole computer. That is my computer goes silent. As soon as I exit ardour2 audio resumes.

Also, although this will probably resolve itself when I resolve the other problem, when exporting a project to audio file from ardour2 it exports silence for the entire duration, even when ardour2 is exited and audio has resumed.

I'm no linux novice, so I'm not afraid of command line solutions (I prefer them actually) however I know nothing about jack or audio editing in linux whatsoever, so if you could be very specific about jack terminology that would be great.

Ubuntu Multimedia :: Getting Jack To Recognize Audio From Microphone

Jun 4, 2011

I have had success with operating JACK, but I am still learning... I can get audio through my microphone into ubuntu and can record into audacity without a problem, however, I do not know how to get JACK to recognize the audio from the microphone (through the normal mic jack)... any ideas how I may accomplish this so I don't need to do all kinds of file conversions and imports to set down a vocal track with the tracks I record (via USB) through JACK?

Ubuntu Multimedia :: 9.10 Not Playing Mp3, Not Sending Sound Through Audio Jack?

Jan 3, 2010

I upgraded to Ubuntu 9.10 recently to find that my computer will not play mp3 files in Rythmbox, Amarok, or Kaffeine media players. All of the FLAC files I have ripped from CDs work, but no mp3 files work. I have downloaded and installed the ubuntu restricted codecs from Synaptic as well as the codecs prompted by Rythmbox rebooted, and still no result.Like I said, the .FLACs play fine.On another note, no sound is being transmitted to my earbuds. The only sound will come from the laptop speakers.

Ubuntu Multimedia :: Can't Get Sound From M-Audio Firewire Solo (using FFADO And JACK)?

Jul 20, 2010

I'm a complete Linux newbie - only installed it yesterday, and have spent hours trying to get my M-Audio Firewire Solo sound card to work. I can hear nothing at all. I know nothing of Linux, but am willing to learn. While I learn though, it would be nice to listen to a little Hall & Oates. I've got to the stage where the error messages I'm receiving don't bring up any results on Google. Here's what things look like (watch out, big pic):

Those sample rate errors appear in the terminal when I start ffado-mixer. I'm running JACK with everything set as I think it's supposed to be, except that 'Realtime' is unchecked.If I start JACK running with 'Realtime' checked, it tries to launch and fails, saying "JACK is running in realtime mode, but you are not allowed to use realtime scheduling. After applying these changes, please re-login in order for them to take effect". I don't know what more it wants me to do - i've already added

@audio � rtprio 100
@audio - nice -10
@audio � memlock unlimited

to /etc/security/limits.conf, and selected the 2.6.31-11-rt kernel on GRUB bootup. I'm a member of 'audio' and 'disk' groups like'm supposed to be. Have I not got the connections right in JACK? Have I got some sample rate settings wrong somewhere?I'm not even bothered about low latency with the realtime kernel right now, I just want to hear some sound

Fedora :: Using Jack In F12 - Unable To Connect To Server

I'm trying to record video of a game I am playing. I am using gtk-recordmydesktop but it records the audio from my mic. This is obviously not what I want.

Ubuntu Multimedia :: JACK SERVER - Unable To Run

Jun 25, 2010

JACK will not run ( eg. the server just won't go! ) When running Rosegarden I can not access the Qsynth/Fluidsynth.In the Rosegarden "manage MIDI devices" menu it now shows ONLY one "General Midi Device" -thats all, and I do not know where to/how to get access to qsynth/fluidsynth to use soundfontsIn manage midi devices I ONLY get the option of "general midi"and then its only through "14:0 Midi through port 0 (duplex)" and no
other channels are available or offered!If I import one of the devices that come with rosegarden ( like Aleisis ) there is no sound.

Also if anyone knows: (& if I can fix the above) how do I set Rosegarden to use a software synth like ZynAddSubFX on the track/channel? External softsynths do not show up, so how do I assign the channel to use them>

Ps: Rosegarden did not install with the help files, even a complete removal and reinstall does not fix this- hats why I may be asking questions which could possibly be in the Rosegarden manual ( but NOT anywhere online that I've found in 3 days of searching- and I'm a research assistant for cognitive sciences- eg: good at researching! )

Here's the JACK output:

First the error:

COULD NOT CONNECT TO JACK SERVER AS CLIENT
-Overall operation failed
-Unable to connect to server

Heres the message window output:

Ubuntu :: Distorted Sound When Plug In Audio Jack

Mar 15, 2010

I am running Karmic (9.10) on an MSI U120 Wind. I dislike netbook-remix but that is beside the point.

Last night I made the biggest mistake of my life which is causing a loss of still counting hours. I decided to do an update, due to having enough bandwidth, and security updates to download.

So it finished, and I went to sleep.

This morning I went to plug in my speakers to the audio jack so I can listen to music loud, and it was all distorted. I changed al 8 or 9 volume controls and nothing. I unplugged the wire from the audio jack, and the sound is perfect on my netbook's speakers.

I have tried different wires, speakers, editing config files, removing and purging related packages, and nothing works...

I have been google-ing for hours and everyone seems to have the same problem, but all of the supposed fixes do not work for me...

Here is a pastebin of my Alsa info : [URL]

I fear switching back to winblowz..

Ubuntu :: Audio Inputs And Jack-sense Cease To Working After A While?

Oct 19, 2010

both audio inputs (I use the integrated mic on my notebook) and jack-sense (integrated speakers/headphones) work properly, as they should. But after some time (from few minutes up to several hours) both of them cease to work simultaneously. After that the mic input levels turning gray and speakers don't work at all (when headphones were connected at that moment) or speakers don't mute when I connect my headphones (if headphones were not connected then). After I reboot, everything is okay again for some time, but then it happens again. Setting mixer levels manually with alsamixer doesn't help at all. I also tried different snd-hda-intel model settings in alsa.conf, but that just made things messed up, so I stayed with auto setting. This way everything (inputs/outputs/sense) works as should until it simply stops working.

It's maverick, ALC268, ATI Azalia (Intel HDA), alsa 1.0.23, but I had this problem with karmic and lucid as well when I tried them. Now I want to switch from Win7, but this is the only thing keeping me from it.
