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.

apt-get –purge remove pulseaudio
Hardy isn’t ready.
check that you have linux-ubuntu-modules installed for your new kernel version. hth
…
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 …

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.
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.
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.
Nice info, added to favourites.
