The sound is gone

[David J Bush]

Under Kubuntu 7.10 my sound worked fine. Now that I upgraded to 8.04, I hear nothing from my speakers. After doing the upgrade, I used aptitude to upgrade nearly all my upgradable packages. The only package I did not upgrade was devscripts which doesn't seem to have anything to do with sound.


david@Achernar:~$ sudo lshw -C sound

Any advice or suggestions are welcome. Thanks!

Open up your backports and do a dist-upgrade.

Under "Software sources" I selected everything:

The "important security updates" checkbox was uncheckable. I hope this is what you mean by "open up the backports."

I upgraded all the packages under aptitude, and rebooted.

I should add that my machine is amd dual core 64 bit, but I am running 32 bit Intel Linux on it.

Open up your volume control and make sure that alsa doesn't have it muted by default.


...and hi from a David A. Bush :)

Try:
sudo apt-get install linux-backports-modules-generic
Reboot
Try lshw -C sound again.

[David J Bush]

I did as you describe.

The sound is not muted. It's also still not there. I appreciate your help!

[David J Bush]

No sarcasm was intended. I do appreciate the help, even though the problem has not yet been resolved. I hope we can continue to track down the bug. Thanks.
