Ubuntu Multimedia :: Rakarrack And Jack Just Will Not Work
Sep 30, 2010
I have everything installed and Jack working fine. I'm in the user group and have realtime enabled and running. My problem is that I can't get my input (the guitar) through rakarrack and out. This is how it is set up:
Guitar is plugged in directly through the Input jack on the sound card (I have tried with the front input, rear, front mic, and rear mic inputs)
I have kde mixer set to allow pass-through of the sound from the input source (I can hear the guitar in my speakers, un-amplified directly from the source). The problem is that I cant get this source into rakarrack with jack to save my life. I have tried all sorts of combinations both physically with the audio jacks and in jack audio. Is that Jack isn't detecting the right input source with alsa or something?

I noticed that any CPU load, while using Rakarrack guitar effects, causes the sound to distort and it generates loads of noise. This actually happens when using anything while running Jack audio. If I'm recording, I get tons of noise on the recorded track when I play it back (and live when monitoring) because any CPU usage seems to interfere with the signals. It even does it live in the playthrough (monnitor).
I realized it had to do with CPU usage when I noticed a pattern with the noise correlating to the plasma CPU monitor widget I had running originally. The noise refreshed when the monitor did. Since then, I noticed that anything that puts a slight load on the system will cause this disruption (even moving a window around, or anything in the background processes).
Anyone who is experienced with Jack audio, and possibly rakarrack as well, know the cause to this? I figured loading a low resource WM and eliminating unneeded processes can help but it doesn't since the recording program itself, while recording, is enough to cause this problem. (I know this because playing the guitar in Rakarrack, without recording and just using Jack to run the sound to the speakers, doesn't have constant noise but when recording, there is a constant noise)

Can't get jack to work. Installed from synaptic (running ubuntu 10.10, 64bit).

I'm trying to compile Rakarrack at my PC, following those instructions.
[URL]
When I try to run "./configure" it says file not found.
I did run a bunch of sudo apt-get install for all of the dependencies, but didn't check if they were all there.
That's what comes out when I run ./autogen.sh
Code:

I have a Dell Studio 1535 and can't seem to get recording from the mic jack to work. I was wondering if anyone has got it to work or not on Ubuntu 8.10 64 bit. I fiddled with the settings in System->Preferences->Sound and in Volume Control: HDA Intel (Alsa mixer), as well as the settings in the semi-CLI program alsamixer, but it doesn't matter what I do. I have failed to get it to record from the mic jack. It will only record from my internal mics, and I don't want that at all.

now half of the speakers plug is stuck in the back of my PC. cant get it out, because it's very deep. i decided to use the front jack for sound but it wont work.already tried alsa mixer and upgraded my kernel.i think the problem is that i need to somehow kill the jack in the back of PC because its still alive and sending signals to that half-dead jack

I have tried every forum that exists, but I have been sadly frustrated in setting up this netbook's headphone jack and internal microphone to work. Basically the speakers work fine, but as soon as I plug in headphones nothing happens, then I unplug the headphones and the speakers work fine. I tried adding the following two lines to the /etc/modprob.d/alsa-base.conf options snd-hda-intel position_fix=1 model=3stack options snd-hda-intel model=dell-vostro enable=1 index=0 one of the other forums told me to do this, but no luck.Also I tried this too: [URL]...

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.

whenever I try and start it, it spits this at me: p, li { white-space: pre-wrap; } Could not connect to JACK server as client. - Overall operation failed. - Unable to connect to server. Please check the messages window for more info.its all greek to me I fiddled with some basic settings, but to no avail, I'm running a dell dimension 9150 with a stock soundcard. To be honest, I don't know what Jack is, but it opens when I open DJplay, so I'm guessing its like Asio4all when running deckadance?

I am having trouble getting the audio to work on this computer (ACER 5570-4765 with PCM Audigy ZS 2) running Ubuntu Studio 10.10. I can get JACK to run without errors but I am not sure if settings are correct. For now I would just like to listen to music using Audacious but I would eventually like to record guitar using Rakarrack (I have this installed but I am having zero luck with this as well).
Here are a few lines from the JACK message screen.
19:13:18.734 JACK is starting...

I have HP Pavilion laptop with two jack outs for audio and both of them work if only one is plugged in. If both of jacks are used, then in only one headphones set there is a sound. I would like to have sound on both of them, so for example two people can listen the same thing on their own headphones.
I'm working on Ubuntu 10.04 and my sound card is:

For starters; although I am comfortable with Ubuntu, I don't really understand these midi and jack things,Ok,so I got a midi controller keyboard which I want to connect to my ubuntu pc to start making some music (play piano and possibly try to make some songs). I don't know if my sound card supports midi, but I got a Roland midi-to-usb converter. I connected it to my pc and downloaded Jack Control. When I fire up Jack control my normal music (using audacious) stops (don't know if this is normal). On the window that appears I hit start which results in an error, which I will paste below:
Code:

I'm using a fedora install mainly for audio work and have everything working well out of the box. My setup is simple:
-Direct cable from Guitar 1/4" > Sound Card input>Rakarrack Guitar Effects>Ardour>System Out
(Occasionally I put a synth/plugin like Zynaddsubfx or jackrack before or after rakarrack depending on what sound I'm going for)
-Jack for all audio transport with synthesizers
I have real time support with Jack and all other programs except Rakarrack. When I launch Rakarrack in the terminal, I get this message:
Code:
rakarrack 0.6.1 - Copyright (c) Josep Andreu - Ryan Billing - Douglas McClendon - Arnout Engelen
Try 'rakarrack --help' for command-line options.
Cannot lock down memory area (Cannot allocate memory)
Cannot use real-time scheduling (RR/15)(1: Operation not permitted)
AcquireRealTime error
However, running rakarrack in root does not display this output, and I assume it has no problem getting real-time scheduling in that case. I did some google searches but the only similar issues that I find are that people can't get RT support in jack except in my instance, I do have RT scheduling with jack, but for some reason I can't get it in rakarrack unless I'm root.
[Edit] I actually have to run jackd and rakarrack in root to get rakarrack to use real time scheduling. But, it isn't necessary for any other jack compatible program that I know of. I'm actually not getting any real time scheduling with any jack application, even though Jack is reporting to be running in Real Time. However, running everything in root fixes the issue even though I would prefer to not have to run as root.

I have an ESI Gigaport HD USB external soundcard which I'd like to use via Jack with my Thinkpad T40 running Ubuntu 9.04.This is the card, it has no inputs and 8 x outputs:

The card is autodetected on plug in. I can see the 8 x outputs in the Jack connection window but I can't run any sound to it. Anything I connect to it on any of the 8 channels is silent.

I had Ubuntu 10.4 installed and JACK was working excellent. I noticed that gnome was a little more than what I needed so I installed the xubuntu-desktop package. After that install JACK no longer works... I run the command jackd -d alsa and I get a bus error. I did a new install from an xubuntu iso and same error.

Why do this? Two reasons:
1) Many of us use JACK for low-latency audio work, but it's annoying to have to turn it on or off to have to allow regular Ubuntu applications to work. It's even more annoying that both can't normally work together -- either JACK or PulseAudio must take control of the sound control. This method allow JACK to do, and PulseAudio just routes to JACK.
2) JACK is kinda super awesome. By routing PulseAudio through it, your regular Ubuntu sound application suddenly get super powers. Pretty easy to do! (Well, we count our blessings in Linux...)
1. DYNAMICALLY You need the PulseAudio utilities and JACK sink:
Code:
sudo aptitude install pulseaudio-utils pulseaudio-module-jack And then run this to get PulseAudio connected to JACK: Code:pactl load-module module-jack-sink pactl load-module module-jack-source Now, go to Ubuntu's sound preferences, and you'll see "Jack sink" in the output tab. If you use JACK Control, you can create a script for the above and have it set up in "Execute script after Startup". Then, PulseAudio will automatically load the JACK sink when you start JACK.
2. BY DEFAULT Edit /etc/pulse/default.pa, and add these lines:
Code:load-module module-jack-source load-module module-jack-sink You can test it without rebooting by restarting PulseAudio. In Ubuntu, PulseAudio is started in the user session, not as a system daemon. To restart it:
Code:
pulseaudio --kill
pulseaudio --start

I can not get sound to exit from my headphone jack, whenever I plug it in, no sounds come out. Notebook model is Acer 3820TG. By the way, I've tried adding the line for HDA Intel with udo gedit /etc/modprobe.d/alsa-base.conf

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:

I have a little issue.
I have netbook Asus EEE PC 1001PX (he's got only one jack for headphone and mic, i dont' know how this could work... but anyway)
I have no sound from headphone, from speakers is ok.
I've already edit /etc/modprobe.d/alsa-base.conf and insert the options snd-hda-intel model=asus at the bottom, still nothing.
I've try also to uninstal linux-backports-wireless... and still nothing.
Card: Intel HDA.

Jack runs, but I can't get sound to play through it. Another thing that happens is when I launch jack, all audio in the system, whether its connected to jack or not, goes off. There are no errors or anything in the messages window. And I checked to see if it was connected to the correct interface. I have a mac mini and I run ppc lucid lynx. The system does detect my hardware, and its not muted. All I want to do is use MusE. Is there maybe anyway to run MusE without jack?

I finally ditched PulseAudio and set up my system with a realtime kernel. I'm redirecting ALSA over JACK. The good: - Awesome, I can get <5ms latency without any xruns! (although 23.2 msec as described below is just fine for me) The bad: - I'm a long-time linux audio user, but have got some minor issues which spoil the fun.
1. Without pulseaudio, the indicator applet refuses to show a volume control applet. The old gnome-volume-control-applet (the one with tooltip!) loads but doesn't show in the gnome-panel. Although I can set the volume with envy24control, it's not quite as practical as using the scrollwheel! Any way to fix this?
2. When I launching any application (such as a terminal) from the gnome-panel, a new JACK connection is created, but not cleaned up after closing the application. As a result, the QJackCtl connection list is flooded with alsa-jack.jackP.8528.xx connections (where 8528 is the process ID of gnome-panel). The jack_lsp command line program shows the same (added spaces after every : to get around the smiley filter):
