No sound using JACK

I don't have any sound output when using Rosegarden. My soundcard is a SB Live! and working properly. Snd-seq and realtime (gid=92, group audio) is loaded, and jackd starts fine. I also have Rosegarden set to autoload a soundfont for my card, and start jack.
I'm at a loss here.

It works fine as root, but that's worthless.
when you say "it" do you mean qjackctl?
when you say "works fine" do you mean that it sounds?
i don't have any qjackctl locale, so it should work after all.
check your soundcard volume and that you are using alsa.
make sure you use udev and that your user is added to audio group
TIP: use kernel26mm and realtime module. You'll get the same performance as if you where root.

  • Can't record sound using the jack in/out on macbook pro 13 os x

    hi
    i bought a new macbook pro 13' intel core i5 4gb with the latest os x version 10.8.2. mainly for sound and video editing
    yesterday i tried to record sound using garage band and through the mini jack port. once i connected an mp3 player to the mini jack port, the sound prefrences window recognized it as headphones and not as input jack as it did on my friend's same mac with leopard os on it.
    it seems like no matter what i try to do (changing instument set up on garage band, restarting the computer with the jack in or out etc...) nothing worked
    i bought this mac just so i wouldn't have to deal with these kind of problems....suppose to be a very user friendly os and hardwear.
    very dissapointing. please if any one has a clue what can be done?

    i'm aware of my other audio interface options, but i would expact this machine to have the basic options every 20 year old pc has, a simple plug and play difault to get audio into my computer. i bought it at b and h in NY and in their specs it says that it's a 'combo kack' - meaning both in and out analog audio ports. after cheaking mac's site it says only headphones.
    also tryied to connect a digidesign mini mbox2, through the usb port, and i had to unplug it, shut down the mbp, restart it again etc.. and it also doesn't always work propely and makes all kinds of digital error sounds.
    although in this case i can't that the mbox is not damaged.
    over all it's very dissapointing. it's my first mac and i figured it would be a much more idiot proof, user freindly work tool.
    if you got any other tips i'd appreciate that
    thanx alot for the focusrite link

  • [SOLVED] No sound from JACK

    I recently set up jack2-dbus, and I haven't been able to get any sound output. Looking at qjackctl's connection's interface sheds some light on the issue. It looks like system is not a writable client. As of now, running any program which uses jack sends output to the PulseAudio Jack Source, which doesn't seem to be playing any audio. Is pulseaudio at fault here?

    Strange. I just restarted my computer today and now everything is working. The system entry appears in qjackctl's connections menu. Not sure what I did to fix it, but it seems like everything is in order.

  • Sound Input Jack

    I use my sound input jack to digitize music from my stereo and also for a microphone for voice recognition software. Switching the lines requires crawling behind my desk, and I'd like a more convenient solution. I've searched for an extention cord that would accommodate the extra-long, 4-conductor microphone plug (as well as the standard plug from the stereo) so I can switch the cords from my seat, but I can't find one. Can anyone suggest a retail source? Or can I use a microphone with a USB connection?
    Many thanks!

    Try a Griffin iMic.

  • I am unable to get sound using apogee jam with my guitar. I can see input levels but no sound. What step am I missing?

    I am unable to get any sound using apogee jam with my guitar in logic pro 9. I am using Macbook pro.

    I think I have done something wrong. I used my Apogee Jam on a guitar project with several audio tracks in Logic Pro 9. And while the Apogee Jam still was connected, I switched to another project with only instrument tracks (synths). I forgot to change the "Built In Input". After I did this, my guitar sounds like crap when I try to use Apogee Jam in the same guitar project, or also if I create a new project. I use Guitar Rig 5 (Native Instruments) as my guitar plug-in. But the guitar sounds strange even if I don´t assign Guitar Rig.
    Can somebody help me?

  • No sound using stereo mixer with speaker balance s...

    No sound using stereo mixer with speaker balance set between approx 95-100% of max to the right
    Setup: good quality functional soundcard, fine when audio not routed via Skype, mixer enabled, Skype mic / audio auto disabled, issue present when tested using a variety of different systems, latest version of Skype was used on all machines being tested
    Issue: When the speaker balance is set approx 95% to 100% to the right speaker channel using the Windows audio control no sound is generated. The issue is absent when audio is not routed via Skype. This would seem to be a Skype bug and would like to report the issue as a bug. Has anyone else encoutered this issue? Is there a resolution?

    Yes, I restarted my computer yesterday and this morning all my sounds is controlled by the left/right blance percentage. 

  • No sound using optic SP

    Hi,
    I have successfully installed the creative X-FI Xtreame on my PC. However i have problems hearing sound using the following configuration:
    I am connecting an optic SPDIF cable to SPDIF out connection at the back of an HD DVD (Neo Neo) the other side of the cable is connected to the optic in connection at the creative panel.
    I am using a 2. speaker system (which I am not sure if they are digital or analogue, although i am pretty sure they are analogue) and they are connected to "line out" connection at the creative sound card at the back of the PC.
    When I play a DVD movie I cannot hear any sound.
    When i tried the same using the AUX input it was ok.
    Can you please help?
    Regards,
    Marcio

  • No sound using internal speakers, but I have sound using headphones

    I just finished installing archlinux with GNOME3 on a laptop, everything were perfect until I detected a problem: I only have sound using headphones, the internal speakers of the computer doesn't work. I followed the official wiki step by step and I never had this problem using other linux distributions.
    Any idea?

    I'm having the very same issue. Each time I boot computer I have to unmute the speaker in order to have sound. Only the headphones are unmuted by default. From what I understand alsa-store and alsa-restore are supposed to run automatically on boot and shutdown only (normally they appear in inactive/dead state).
    I have tried to run 'alsactl store', but this won't help.
    The whole thing start happening only recently (late December). I have arch on this laptop for over 3 years and it was fine as far as I remember.
    EDIT:
    I have just found that this issue is due to pulseaudio 2.1 -> 3.0 upgrade. After downgrading to 2.1 it works as expected.
    EDIT2:
    Maybe you will find that useful, a temporary "fix". I have added to startup applications (in my case in gnome-session-properties):
    amixer -c 0 sset Speaker Playback 95%
    which just simply sets the speaker volume to 95% each time I log in.

  • API indicator about sound using by the Flash Player

    Is it possible to add an API indicator which will inform about sound using by the Flash Player?
    I mean situation from web browsers where you mostly has few tabs opened and don't know which one is playing the sound. It would be great if Flash Player instance could inform about playing sound. Some kind of API, dynamic HTML tag (playingsound=TRUE/FALSE) or something like this which can give an opportunity to browser to react on. The best example is ofcourse Chrome which has own implementation of Flash Player and adds small speaker icon on tab which is playing the sound.
    The main reason of this thread is issue 486262 – Provide visual indicator as to which tab is causing sound from Mozilla Firefox Development but it can be global feature and helpfull for every browser and other applications using FP.

    Could you do me a favor and post a screenshot of this box that is appearing?
    How do I capture and post a screenshot or video?

  • Cracking sound using Chrome

    I recently bought a Macbook Air and I am experiencing a weird behaviour. When playing videos on YouTube (or others) and music from Grooveshark and others using Chrome (latest version 29) there is a cracking sound. It seems like speakers are broken, like an old tv. But if I play the same videos or sound using Safari, Opera or Firefox there is no cracking sound.
    Any ideas?
    Thank you

    Considering many other problems reported with Chrome, Chrome and Mac OS's seem to have a bad fit.  The solution is not to use Chrome.

  • How to use 5.1 sound using mini jack output ?

    Hi there,
    I have an iMac 27" core i5, and I would like to plug my Dolby 5.1 6-speakers-system (including sub) to it. How can I do else than using the mini-jack output which produce only stereo 2.1 sound ?
    NB : my speaker system uses 3 mini jacks (green, pink and black) for rear speakers, front speakers and center/subwoofer.
    Thank you for you answers and proposals.
    Best regards,
    Pierre Goffart

    thanks again but perhaps i didnt explain clearly enough. I dont want to have simultaneous optical input and output, other wise there wouldnt be a problem. The speakers i have are 5. computer speakers. The computer is connected to them via 3*3.5mm jacks from the sound card to the sub, the other sattelite speakers are connected by audio rca to the sub. My speakers have no optical-in on them, hence having to to re-route the sound through a sound card (if it would work). Essentialy using the sound card as an amp or as a big optical to 3*3.5mm jack adaptor.
