    Re: Sound troubleshooting

    Sound not working suddenly for movies and music, but works for chrome


    MamboJumbo,
    Ubuntu13.04
    VLC,Banshee

    Helloall,

    Iam having an issue where my sound stopped working on a new session. Ihad had a few sessions under 13.04 already and sound was fine. Now,the sound settings will crash right away if i launch it, and I willhear nothing if I launch any movie on "Movie" or VLC, samefor music on banshee. However, sound on youtube or other video siteswork fine. I have tried starting VLC first after reboot and it didnot make a difference. I also tried changing the audio engine in VLCand that did not help either (alsa, pulse, etc...)
    Ilooked online quite a bit and did not find anything similar to myissue but did find some troubleshooting clues

    I did run things such as alsamixer etc and other scripts included in this thread but it did not help.
    Trying to launch "gnome-control-center sound" in terminal gives me a
    "Segmentation fault (core dumped)"


    And here is the alsa info txt output
    !!Soundcards recognised by ALSA
    !!-----------------------------


    0 [Intel ]: HDA-Intel - HDA Intel
    HDA Intel at 0xfdff8000 irq 44
    1 [MobilePre ]: USB-Audio - MobilePre
    M Audio MobilePre at usb-0000:00:1a.7-5.4, full speed




    !!PCI Soundcards installed in the system
    !!--------------------------------------


    00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 02)
    When I first set up ubuntu, i tested every speaker of my 5.1 system via the sound settings menu. Now if i do a 5.1 system test in terminal (since my sound settings crashes) it times out.

    What should I do?
    Thanks

    @k-laminero: try resetting your pulseaudio settings:
    Code:
    rm -r ~/.pulse*; pulseaudio -k

    Thank you for your answer.
    I did try that before and here is what I get

    rm -r ~/.pulse*; pulseaudio -krm: cannot remove ‘/home/iohan/.pulse*’: No such file or directory

    I have no idea why.

    Re: Sound troubleshooting

    That probably means pulseaudio isn't starting at all. Maybe delete the configuration and try again:
    Code:
    sudo rm -r /etc/pulse
    sudo apt-get install --reinstall pulseaudio libasound2
    pulseaudio -k
    If that doesn't work, you can make a log file: https://wiki.ubuntu.com/PulseAudio/Log

    Re: Sound troubleshooting

    No sound working here at all, aplay -l finds no sound cards, alsamixer won't run at all "cannot open mixer: No such file or directory" yet it is installed.

    I had sound until there was a Kernel upgrade.. running Ringtail here. Any help would be appreciated

    Sounds like it could very well be: https://bugs.launchpad.net/ubuntu/+s...x/+bug/1169984
    Try the workaround: https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS

    I've tried that but I get:
    Code:
    Error!  The dkms.conf for this module includes a BUILD_EXCLUSIVE directive which 
    does not match this kernel/arch.  This indicates that it should not be built.
    Any other ideas?

    Re: Sound troubleshooting

    I hope I'm not repeating anybody else's problem that has already been covered....I searched and couldn't find it. Anyhow, the problem is that after a certain amount of time of playing sound my speakers stop working (but sound can still be heard through the headphones). If I put the computer to sleep or reboot the speakers work again but fail again after some time (anything from 2 seconds to 15 minutes). I have tried the following to no avail:

    1. unmuting and disabling automute in alsa mixer
    2. reloading alsa
    3. reinstalling alsa
    4. installing new kernel
    5. installing old kernel
    6. installing alsa development ppa

    None of these work. The only way to continue using sound is to insert headphones or reboot/sleep.

    Most frustrating perhaps, is the fact that I had exactly the same problem some months ago in 12.10 and then in 13.04 and both times it disappeared after some time. But now its back with a venegance. Please advise.
