How to fix no audio output device on Alienware m17x r4 (7970m, windows 7)


Recommended Posts

I've had this issue a while ago on my Alienware m17x R4 with 7970m and windows 7 Ultimate x64 and I've been trying to fix this since, but I've found a solution :DIt's probably more simple then you thought it would be :PBasically, what you do is you switch to iGPU Intel HD4000 first (FN+F7),then you have to install this audio driver (A01, 4/30/12, Creative Labs CT9570, Audio_Creative_W74_5NJ7K_A01-Setup_ZPE.exe), driver from their website,Switch back into dGPU again,there you go :DHope this helps

Well, I had the same problem, searched month for a solution in the web, applied all the recommendations - tip & and tricks. No solution fixed the problem. The Soundcard issue is a on & off story for some of us.

At the end I called Dell Support. and two days later they replaced to motherboard on site. No everything is working fine.

I need to add, I have a 3 year on site support contract. And it's worth to consider that in the beginning of a every DELLienware purchase.

But for all others outside w/o a contract, Call dell and ask for the price of a refurbished Mother Board. Maybe you get a good price. The replacement of the Mobo is not rocket sience.
