dear lazywebs…

April 2, 2008

My sound broke. There is a good reason why my sound shouldn’t break. I upgraded Xubutnu Gutsy to Kubuntu Gutsy (apt-get install kubuntu-desktop) and then Kubuntu Hardy (apt-get update && apt-get dist-upgrade) and now my sound won’t work. I can’t see any reason why this would happen. Specs:

Under System Settings-> Sound System I have the ‘enable the sound system’ button clicked (sidenote, why is this even an *option*?)
Audio Device configured to Autodetect my audio device.
Running alsamixer in a konsole, I see that all my sound is enabled
I don’t have the mute button enable.
This is true for movies, music, etc.
When I open up kmix, instead of the slide button being blue (it is all the way up), it is grey.
When I try to play a song in Amarok, the amarok slide button is grey, instead of blue. This is the button that leads you skip to a certain section of a song, etc.
Restarting HAL doesn’t fix the issue

Any/all ideas are appreciated.

    As far as I know the command “apt-get update && apt-get dist-upgrade” is the upgrade path for debian, and not ubuntu (at least since feisty).
    Uprading ubuntu needs a few more steps that are performed either by the upadate-manager or by do-release-upgrade if you prefer command line tools.
    Please read the ubuntu wiki about upgrading:
    https://help.ubuntu.com/community/GutsyUpgrades

    Hardy brings PulseAudio to Ubuntu, and you didn’t make a proper upgrade hence your sound broke …

    Cheers

    The “sound system” is aRts – nowadays you’re better off without it, really.

    Apart from that, I don’t have any clue about your problem. nixternal is right, file a bug.

    Try Kubuntu Hardy LiveCD, will the sound work?

    Just a thought – perhaps you have a sound demon hogging your soundcard?
    Try and play something not through a kde program but using alsa directly (for example XMMS with alsa plugin) and see how it goes…

    Are you using kde3 or kde4 – on kde3 arts sometimes has an issue when it can’t have exclusivity on the sound card.

  7. Try tinkering with alsa/oss (it dipends on what you use)

    This is actually a known bug in the kernel.

    Look at Kevin Kubasik’s blog on how to fix it for now.

  9. Catch me on IRC in a couple hours. You know the drill: have your bug report’s URL handy along with the alsa-info.sh output.

  10. Nice info, added to favourites.
