In the sound settings, check what device is selected in 'Play sound through'. It should be 'Built-in Audio' and nothing like 'HDMI sound', etc.

If it is, change the default output device to 'Built-in Audio' and restart.

This url ( describes the same problem i am having ; though my left speaker isn't working. I have also tried with a live cd 'try ubuntu without install' option; the same problem persists. Just want to make sure if this is a hardware issue or is it related to ubuntu so that i can contact the h/w vendor or try reinstalling the OS. – Ankit Jul 15 '12 at 11:12
