Windows 7: Dolby Control Center 'No audio endpoints found'

Im on a Toshiba Qosmio X305 with Windows 7 im having problems with Dolby Control Center not starting im currently using Realtek HD Audio R2.15 but it comes up with 'No audio endpoints found' im just about to switch to R2.17 to see if that works i had Windows Vista previously on this laptop and dolby control center worked so it must be something to do with drivers for something in windows 7. Does anyone know how i can fix this problem?

Thanks.

UPDATE: Install R2.17 works now sorry guys guess this will be good for other people that has this same problem to know that its fixed in R2.17

Dolby control center worked for awhile on windows 7 x64 but now doesn't. It aborts with an error message when starting.
