On Dell Alienware 14x Ubuntu 12.04 sound was working. After few weeks it stopped working. I played around with the sound settings choosing between the different options. I thought it would be wise to disable sound for a while and then enable. This changes the sound settings. The ability to choose options disappears. So after disable once, it will disable forever. Is there a documented way to get sound or sound options back?
Ubuntu is a struggle.

Above "Test Sound" the select list to choose between options is gone.
