I have suddenly lost all sound from my Dell XPS M2010, I think this happened directly after an update that I carried out on my Logitech Quikcam. I have uninstalled Quickcam and tried and then reinstalled Quickcam and tried but still no sound. I have tried the Playback controls and it is currently playing back via the Digital Output Device (S/PDIF).
Yep - this I run into every start up, or every awake session from Standby - the problem is that the default sound device changes - I've gone through the control panel, and put a shortcut to the Sound mechanism in my taskbar - then when it changes, I just modify back to the Speakers/Headphones setting - I usually have to change stations on Pandora, or skip to a new Youtube, but it all works our very quickly.

Yes have restarted the machine still no sound unfortunately.
since you uninstalled the program, have you restarted your computer?
this issue is possible caused by the sound driver is locked into use by the webcam and other resources/players cannot access it.
