I just installed the Ubuntu Studio packages on "normal" Ubuntu, 10.04 -

I'm trying to run this on a Dell Mini 10v netbook.
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.
Just got Studio 9.10 running and the RT kernel installed. I have a Prescott P4 3.2ghz (hyperthreading) and i encountered what looks like a common freeze problem. I am guessing my cpu will not be supported in the RT kernel since it is pretty old now.I added nosmp acpi=off during boot at the Grub2 menu and it booted fine and I was able to capture some video great.
My questions is, if I remove the smp support by using the nosmp option, do I still benefit from the RT kernel or would I do just as well with the generic kernel I have installed?Eventually I will upgrade do a new system board and processor but for now I just got some life back in this one by switching to Linux
I have investigated loads and loads of options and haven't really yet come across what I need.
I wish to stream the microphone input from a PC using Lucid to another PC also using Lucid on the same network. I don't care about the quality, however, latency is really important. I hope to use it to monitor the cries of my baby daughter, so the lower the latency the better.
I have tired various options:
- FFserver and FFmpeg - latency of over 30 seconds
- VLC - couldn't get it to work with my mic and maxes out the CPU
- ssh server 'cat /dev/dsp > /dev/dsp' - latency of around 5 seconds by audio keeps breaking up with huge delays
- icecast2 and darkice - latency of around 7 seconds but no audio breakups
I've been reading on maybe using PulseAudio to stream the input, but I am not sure if it will work or not...
how to get near real-time streaming audio? As I said, it is the realtime, not the quality that is important...
is there a realtime or low-latency kernel in a repository somewhere for OpenSUSE 11.4? I know I can just compile a rt kernel, but that's a bit tedious and I'd like to avoid it if possible.

I can be granted permission, and I'm in the proper groups, but pulseaudio tells me I can't get permission.. I wanted to see if anybody else had this problem / knew of a solution / isolate whether it is a pulseaudio, policykit, whatever problem, before I post a bug upstream.

I installed ardour on my F11 box, and both jack1 (0.xx, in /usr/bin) and jack2( 1.9.5, in /usr/local/bin/). Now when I try to start ardour, it balks about being unable to start jack. On the ardour settings page, I tried changing the JACK server path field from /usr/local/bin to /usr/bin, to no avail.
On the cmdline, here's what I get when I run, manually jack1 and jack2:
JACK1:

That prompts me to think that JACK1 is fine... but still ardour won't start up.
I am a simple musician who bought a laptop that didn't have windows, nor can I afford a Windows license (being a proper poor musician and all). I have an M-Audio KeyRig 49 midi controller that I would like to get some sound out of. How might I do this? I have jack, qjackctl, qsynth, et al but forget qsynth... I can't even get jack to start! I just need to hook this thing up to a piano sample and I'll be happy as anything. I understand that system information can be useful so here goes: Running F14... here are the jack messages (btw, ctrl C does not work when trying to copy from the jack messages window, despite the contextual menu saying it should. That sucks. where do I submit a bug?)

I have already seen the Fedora Musician's Guide [URL] which is long on theory but short on practical how-to documentation. Is there a better doc I can look at? Do I need to download some special drivers to get this midi interface working? If I plug this thing in to my friend's Mac and run GarageBand, it 'just works' (though GB's piano samples are fairly horrific considering how expensive macs are.) I already own some decent soundfonts but without working jack it seems they aren't much use.
I installed the libffado from Slackbuilds.org yesterday on my -current box, and followed the instructions in the README for configuration. After I did that jack wouldn't start at all, insisting that there were no recognized drivers, even when I had the alsa driver selected (alsa is working fine, by the way... I have sound). After doing some more research I uninstalled jack and built Jack2 (1.9.6) from source with the following configure options:
Code:
./waf configure --firewire --alsa --dbus --enable-pkg-config-dbus-service-dir
Now when I try to launch jack (regardless of selected driver) I get the following message
[code]....
attempting to start Jack using the qjackctl frontend...code...
then Jack stops... how do i start Jack successfully?
I installed jack but it won't start either on real, nonrealtime, terminal or qjackctl.It starts a loop of alsa driver xruns until I stop it.
View 9 Replies View RelatedFor 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:

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.

I just realize that when I plug in my headphones in my laptop, the sound in the laptop's speakers continues to play and I have no sound on the headphones. This is the output of the 'sudo lshw -C sound' on my system:

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
[code]...
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! )

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?
View 3 Replies View RelatedI 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):

I am trying to set my computer up to do sound sequencing. I want to plug my MIDI keyboard in and record with a sequencer. Running 10.04, was following a tutorial on installing JACK, and my audio stopped working. Since then, I've gone through all guides I can find, some advising an upgrade of ALSA, some saying to use OCC. I've tried both, but nothing seems to work.
I suspect it may have something to do with libjack0. I could not install jackd because it claimed libjack0 to be the wrong version, and for some reason I couldn't upgrade. So I uninstalled libjack0, then installed jackd, which automatically included the version of libjack0 it wanted. After that, I could get the JACK server running, but the computer had no sound.
I will post whatever logs or information necessary to troubleshoot, but I don't know exactly how or what to post. If you need logs, please tell me how to get them.
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 have a Dell Vostro 320 running Ubuntu 10.10. I can get sound through the onboard speakers but when I plug headphones into the jack, the onboard speakers mute (correct behaviour), but no sound comes from the headphones (incorrect behaviour). The headphones do work with other sound sources.I have made sure all the alsa drivers are up to date and correct and the system is seeing the sound card OK according to aplay -l:
The alsamixer run from the command line or Gnome shows "Master", "PCM", "Beep" and "Capture" all normal with nothing muted. The alsa-base.conf file has the following as the last line as per various posts that seem to have a fix for this problem:options snd-hda-intel model=dell-vostro position_fix=0 enable=yes.
I'm on Ubuntu 10.04 64bit, and I've got JACK and Pulseaudio both installed, though I don't run them simultaneously. I also have LinuxSampler and Rosegarden, and I have the necessary ALSA drivers. Pulseaudio can output to my external sound card, but JACK doesn't, even if I tell it to. I've seen its full name (Guitar Rig Mobile IO) and chosen it as the output device under Settings, but to no avail. It still sends the output to the internal (and crappy) sound card.
