While using Ubuntu 10.04 my system worked perfectly, now that I've upgraded via the Upgrade Manager, there is no sound on my system. My computer is very Ubuntu friendly, as I've never had this problem with any other version of Ubuntu. What can I do? If I need to reinstall 10.04, or roll back to 10.04, how do I do that? If I can fix by reinstalling 10.10 how do I do that. I dual boot with Windows 7 Pro and Ubuntu 10.10.
