Ok, I have an interesting problem. I just did a fresh install of 10.04 LTS and every format of video that I attempt to play (either online or downloaded) plays for a little bit then makes a buzz/cracking sound and fast forwards or crashes that window. The sound goes out after that also, fixable only by rebooting. Then it will do it again.
Is there something that I missed?
I would ask my cat to fix it, but he doesn't have opposable thumbs!
