Trying to solve a NO SOUND issue in Unity on 14.04. Sound Settings now unstable

Question

If I focus on 'Analogue Output built-in audio' in Sound Settings the dialogue becomes unstable - very rapidly toggling between 'Analogue Output built-in audio' and 'Headphones built-in audio' but 'Digital Output (S/PDIF) built-in audio' is stable and available but there is no sound from any source. I have tried several un/reinstalls however still no sound and the toggling persists.
