I've installed Ubuntu 14.04 64-bit, and very new to Linux. My sound worked initially. But when trying to install new drivers from Realtek, for some reason my sound has not worked since. I don't even know how that is possible, because all I did was download a package that appeared to need compiling before I could execute the installer. Regardless of what cause the failure, I need help in getting my sound back. I've installed Steam and one game(Portal) to see how it functions as well as streaming games. Portal ran without issues other than not having sound. I knew I had sound so checked back with online vids where I had sound. So somewhere along the way my sound drivers quit working. I'm also having other issues: I can't get flash installed on Ubuntu 64-bit. Is there another software I should install instead of Adobe? Do all downloads require compiling before they can be executed? I've never compiled a project before, so this is all new and confusing to me. But I can learn, I just need to know if it is necessary first. Am I wasting my time with Ubuntu? Should I consider another distribution instead?
