Windows 7: No sound through HDMI?

Ok I don't have any sound coming through my HDMI



I have the SPDIF hooked up from the mobo to one of my two graphics cards.

I have 2 Asus Nvidia 9800GT

The HDMI is going to a 46" Samsung 750

Technically I have the HDMI and SPDIF set up through the card that is in PCIx16 #2

Does it have to be hooked up through PCI #1?

Suggestions on how to get this to work?

Thanks.

HDMI has its own sound on most if not all video cards.
That is what I have read at least.
SPDIF would go direct to the TV wouldn't it?
TV and moboard manual might or should tell you how to set it up.

HDMI on my Asus you run it straight to TV or monitor with speakers.
I haven't tried it but my video card instructions say to do it that way.
It has its own Nvidia sound card built in.

Hope that helps and sorry if it doesn't.

The SPDIF is internal and goes from mobo to graphics card per nvidia SPDIF instructions. (there is a special SPDIF port on mobo)

The only thing goin from computer to tv is HDMI (which does both video and sound)

Tv has built in speakers.

I switched everything to PCI #1 and still no dice.

The SPDIF port on the other card was different from the first card I tried even though they are the same card which is weird.

Do I have to enable sound through HDMI somewhere in Windows 7?

I should note that under sound in the control panel, there is no HDMI icon?

Just Digital Output and Speakers?

Why isn't it showing HDMI?

And mods please move this to sound. Thanks.

When you right click on the volume icon, and select playback device, do you see the HDMI device?
If so, you need to select it.

Not on the Nvidia 8xxx and up (8xxx, 9xxx, most of the GT/GTS/GTX 2xx) series cards that, for those you have to do the following,

Guide: 8800GT/9800GT/9800GTX Sound over HDMI (Now including Creative cards) - Overclock.net - Overclocking.net

A few of the low end G and GT 2xx cards do have a built in sound card like the 4xx seties and up (there was even a rare OEM version of the 7600 called the 7650 GT that had built in audio and a HDMI port).

Seeing as you have a TB card listed for sound you have the onboard audio enabled and the drivers for it installed if you are connecting to the motherboard header?

No that's what I was referring to. HDMI isn't showing up at all in playback devices?

Did you connect the SPDIF cable to the motherboard header or the one on the sound card?

If the motherboard, is the onboard audio enabled and the driver for it installed?

I'm using mobo SPDIF

I guess I don't know if the inboard audio is enabled and the drivers are installed? How can i tell?

For some reason I remember having to disable the onboard to make my turtle beach card work, but I could be wrong.
