Sound Output Through HDMI

[ZombiePotatoSalad]

I have my GPU, a GTX 960, hooked up to my TV through a Display Port-HDMI Adapter. I have an HDMI cord running from my GPU to my LG receiver, and I'd like to use it to get 5.1 sound, or at least get stereo through all my speakers if possible (it currently only outputs through two, from the RCA cords).

After hooking everything up, I go to check my Playback Devices, it lists the usual suspects, but no HDMI. I make disconnected and disabled devices visible, and there it is, HDMI output... to my TV. Why is it detecting the DisplayPort to TV as audio (when I'm just using it for video), and not the HDMI-receiver?

Never mind, looking on the back, I saw "To TV" for the HDMI port, which was covered by a sticker. Looks like I'll just have to use Optical.

Because your TV's hdmi input accept both Video and Audio. If you are using a second hdmi port to output audio to you receiver i think you need to change screen setting to screen mirror.

Your receiver most likely has HDMI pass-through.
Connect hdmi cable from GPU to HDMI-in on receiver and connect hdmi cable from HDMI-out on receiver to your TV.
