The computer’s sound just didn’t work. And earlier today I actually dropped the computer – for the first time, I should add. I also recently updated to the second Ubuntu 10.04 ???beta, and I started to panic—what was broken, what was wrong? I checked through the configurations and the drivers, tried out two different headphones and one external loudspeaker, googled around. I then tried rebooting the computer, and whoopsidoopsi it worked. Sometimes I just wish I’d start tackling every problem with rebooting.
