    HD Graphics 4600 HDMI 5.1 Sound Output to TV.


      So I have a home theater setup basically I am trying to pass 5.1 surround sound from my pc to my receiver.


      My setup is:

      [PC]===HDMI=== [TV] ===OPTICAL===[RECEIVER] === [Speakers]


      PC info:

      Asus n550jv

      Windows 8.1 64-bit

      Intel Core i7-4700HQ

      8GB RAM

      Intel HD Graphics 4600

      NVIDIA GeForce 750M


      TV info: Vizio E420i-b0 Smart TV


      Receiver info: Sony STR-K750P


      The problem I am having is my PC will only recognize the HDMI connection with stereo sound.[pic]


      My first thought was that the tv could only accept signal in 2 channels.

      I did some research on my specific model and discovered that it DOES indeed support full surround HDMI pass-through. I confirmed this by talking to a vizio customer support rep who tried to help me with my problem. She said that it was a problem with my display driver(Intel Display Audio), leading me here.

      How do I get my pc to recognize my sound system?
