No sound through HDMI, radeon hd 6770


So i built a new computer today. I do not have a normal monitor. I'm using my TV as my display. 32" LED tv. I cannot get sound at all. When i go to control panel->sound->manage devices i see my video card there says something like AMD HDMI sound or something. but it doesn't have a green checkmark. I've been searchin all day and cant't find an answer. I'm using a Radeon HD6770 Says it supports sound. this is taken straight from their website for this card.
Integrated HD audio controller

Output protected high bit rate 7.1 channel surround sound over HDMI or DisplayPort with no additional cables required
Supports AC-3, AAC, Dolby TrueHD and DTS Master Audio formats

  1. Try this out:

    right click on your sound volume control (i'm assuming you have windows 7) and select playback devices.

    Under playback devices, you should be able to right click on your audio output (there might be a couple, one might say HDMI or digital output) and select set as default.

    Basically try one of them until you can hear sound.
  2. Tried doesn't work. there are 4 options

    amd high definition audio device
    not plugged in

    high def audio device
    not plugged in

    Digital Audio (s/PDIF)
    high def audio device

    Digital audio (S/PDIF)
    high def audio device

    the AMD HDMI Output is what im wanting but it says not plugged in.

    the two that say ready dont give me sound.
  3. try disabling/enabling it.. the amd hdmi audio output...
  4. tried, didn't work. Even tried disableing everything and only leaving the AMD HDMI out enabled and still nothing. I checked to make sure the driver was installed and it is. says the device is working properly. But still no sound.
  5. BTW im using a DVI to HDMI cord. Should i use an HDMI to HDMI cord? and if so how? i tried and I watched it boot up but it never got to the Windows sign in screen
  6. NVM figured it out. this is now Solved.

    Just needed to use Hdmi to Hdmi. when i originally did it the i didn't have it plugged in snugly. THanks for the help everyone!
