Title says it all. Occasionally but frequently I lose sound: external speakers and headphones both make no noise. I just realized that this tends to happen (perhaps only happens) after starting the computer following hibernation. Rebooting always fixes the issue... but I'd hate to tell my friends that my home Ubuntu system is less stable than the Vista one I use at work!
Any thoughts?
really don't know how to fix it permanently, but if you use alsa you can try by:
sudo alsa force-reload
Bye
This should help
D.
What release are you using?
You can also try reinstalling alsa by pasting this in the terminal
sudo aptitude --purge reinstall linux-sound-base alsa-base alsa-utils linux-image-`uname -r` linux-ubuntu-modules-`uname -r` libasound2
That was Xubuntu Intrepid.
The problem has gone away now that I've moved to Ubuntu Jaunty.
