I have just installed the latest version and I have no sound. I tried all solutions I could find on the web, including drivers from the sound dev repository, running alsamixer, etc, but nothing helps. Would someone please help? I am new to ubuntu, I have no idea where to look. Microphone works, and it seems to recognize my laptop's on-board sound.
