HDMI cord from graphics card to monitor does not have sound

So I finally built the computer that many of the awesome people on here helped me with, and I am currently writing this on it! However, I do not seem to have any sound. The HDMI cable connects from my GTX-780 straight to my ASUS monitor. I was told HDMI carries sound as well as visuals, so I am wondering if I have to install drivers or something. Any help would be greatly appreciated! Thanks.

  1. You definitely need to install the motherboard CD drivers and the latest driver downloaded from Nvidia.com
    Then you need to go into sound properties and make the HDMI output the default sound device.
  2. Can you provide the model and brand of the 780? Like EVGA, ASUS, MSI, etc? The 780 is relatively new and the reference design (idk why a manufacturer would remove a feature) most likely supports it.
  3. ASUS sorry

    I'm downloading the latest driver from Nvidia Geforce right now.

    It appears that their 780 in fact does support audio through HDMI, so the problem most likely is that the software isn't set to use HDMI as default.

    To fix this problem, navigate to Control Panel > Hardware and Sound > Sound [This will bring up a pop up window] then find something like "Digital Display audio" or "HDMI Audio out" or something like that. Right click and select "Set as Default Device", and you're done!

    If an HDMI audio device doesn't appear to be there, try right clicking in a blank space in the audio device window and selecting "Show Disabled Devices", then find it and set it as default.

    If it still isn't there, it is possible that the card isn't detecting an audio capable HDMI device, try going back to where you set it as default and selecting "Show Disconnected Devices". If you can see an HDMI audio device then, then the problem is either
    A. Your graphics card/The HDMI out port,
    B. The HDMI cable,
    or C, the Monitor's speakers/connection.

    If this solved please don't forget to set as best answer! Thanks!

    It just says not plugged in, yet it is.
  7. Then the problem is one of the 3 things I listed. I would start by getting an exchange on the cable (if you can) and also confirming that the cable can carry an audio signal.
