sorry, I can send you my Alienware service tag: Alienware M17x BDPSD12 , Dell supports are crap, the latest driver for Audio is wrong with MaxxAudio!
It must be Dolby Digital Plus Home Theatre version Dolby Digital Plus 126.96.36.199 or 188.8.131.52 (I use 184.108.40.206)
Attach the edited setting info file here.
Before I used very simple way to install Dolby Digital Plus Home Theatre with latest drivers, simply copy the folder of DS1 into the drivers folder, but now even if I do that does not install it, I should install Dolby Digital Plus Home Theatre after driver!
This driver series doesn't work with your legacy Fermi GPU. Go to R390 series
