Ran into some breakage today on Ubuntu.
The last time I ran Ubuntu, I had installed Virtualbox and I noticed it had done something to my sound.
Today when I started up, no sound. The volume control applet displayed "muted". Double-clicking on it gave the following message:
"No volume control GStreamer plugins and/or devices found."
Clicking on it once had earlier said that my sound card wasn’t configured. Bugger. And now I barely have anything on my System > Administration menu.
UPDATE: I figured out the problem! When I used Ubuntu’s "users-admin" program to try and move my account into the vboxusers group yesterday, that actually took away all my user’s permissions, except the permission to use "sudo". Doing "gksudo users-admin" and turning all the checkboxes on solved the problem - you see, that program allows you to deny access to the sound card to a particular user, and that’s what it was doing.
Unfortunately, it’s close to impossible to notify Innotech themselves and put that useful information onto their FAQ page. At some point in time I’ll have to check Launchpad and file a bug report against users-admin for that - that’s a terrible bug!
