Not getting sound from TV when connected to PC

[Ksingler]

Hey,

I'm having trouble getting sound from my HDTV when connected to my computer.

Connected through HDMI cable
TV: Vizio E470i-A0
GPU: GTS 250

Under nvidia control panel > set up digital audio > the hdmi is set to my TV.

Under the sound settings, only my speakers are shown on the "playback" tab and on "recording" tab it now shows a stereo mix that looks like a video card, it is checked.

I uninstalled and reinstalled the sound drivers.

My video works just fine. I have my monitor and TV set to duplicate these displays. When watching a video, my speakers give out sound but nothing from my TV.

I unplugged my speakers but that didn't do a thing for my TV. I changed digital output to off, dolby digital, and PCM. Also changed analog to fixed and variable. I tried all those combinations and nothing.

Any ideas?

Do you have any other hdmi cables laying around? I would try using a different hdmi cable and also check for dust in the hdmi port on your computer.

Using a different HDMI cable made no difference. Any ideas on why the TV isn't showing up in the playback tab under my sound settings?
