Ubuntu Multimedia :: Redirecting ALSA Over JACK 10.4 - 3
Sep 9, 2010
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):

I have a new install of 10.10 on a Toshiba Satellite with a dual boot of win7. I installed 10.10 and on the first night I swore the headphone jack sent sound to my external speakers (may of been plugged in during install). Then the next day I couldn't get any sound out of the jack. Sound kept coming out of my internal speakers. In win7 the jack worked normally. In Ubuntu I have checked sound preferences and my alsa mixer. There is no listing for a headphone jack (so it is not muted).

I am using Ubuntu 10.10 x64 on a Dell Studio XPS
I am unable to get JACK to make any sound from any of the applications which plug into it.
Code:

I'm at the tail end of my upgrade from Lenny to Squeeze and I think this sound issue is the last one I have.
As usual I've tried hunting for some answers but it gets very confusing when people are using KDE or PulseAudio or Ubuntu or slightly different configuration to what I have.
My config:
Debian Squeeze 2.6.32
Alsa (just because I was using that in Lenny and it was working, no other reason)
Gnome
Rhythmbox
Skype
Skype is pretty good - it has the sound configuration built in, so I say ring the speakers and it does. I say talk to the headset and it does. Rhythmbox is my music player (again just because I was using it under Lenny) however it only wants to play through the headset. I can't seem to get it to play to the speakers attached to the rear port.
Summary of some settings (transposed manually)
# aplay -l
*** List of PLAYBACK hardware devices ***
card 0: Headset (Logitech) device 0: usb audio
subdevice 0/1
card 1: Intel HDA device 0: ALC883 Analog

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.

I have recently been forced to do a hardware upgrade (my previous mobo died). Now, sounds works ok with,amarok because kde has recognized the new hardware and switched to it.
..... does not work, likely because flash uses alsa-oss which is probably not configured automatically. I have tried uninstalling and reinstalling both alsa-oss and flash, but it didn't solve the problem.

Today I tried to use padevchooser on Natty to send my laptop audio to my home media machine (which has the good speakers) using the "default server" option. Turns out padevchooser doesn't work on Unity and the threads I have seen say it is deprecated for other gui tools,
So what is the easy gui way to switch from my local pulse server to another one on my LAN, without using padevchooser, or switching off Unity? Or is this a regression?

I'm trying to update ALSA, following the instructions here: SDB:Alsa-update - openSUSE.I'm not sure how to proceed at STEP THREE. There are two sets of instructions, based on whether or not the kernel has been updated. I'm not sure if it has been. How can I make sure?

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:
22:46:06.556 Patchbay deactivated.

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:
[URL]
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

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 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.

I had sound. My sound stops working after install jack. Jack server starts well, and the jack log shows no error messages. If I run Muse, it recognizes jack and show no error messages, but I have no sound output. Where should I start investigating? I'm using Karmic.

I'm dual booting Windows 7 and Ubuntu 9.10 64bit on a new HP laptop.In Ubuntu, I'm not getting any sound from the headphone jack. I've tried a couple of different solutions but haven't had much luck. Sound works through the internal speakers in both Windows and Ubuntu. Sound through the headphone jack works only in Windows.The sound card is a IDT 92HD75B3X5.This is a fresh 9.10 install, save for the changes mentioned below.I've attempted to use the gnome-alsa fix that's mentioned in a few threads, but I don't have a "Headphone" tab to "un-mute".I've attempted to recompile the driver as mentioned in this thread
