GeForce 8400 GS - Hard Time Getting HDMI Audio

[DasFox]

I have a Gigabyte GeForce 8400GS which uses a spdif plug that I connect to my motherboard and my box has onboard Realtek HD audio.

I'm a bit new trying to understand HDMI, never really used it till now. I guess there are some cards that don't have a spdif plug that you need to connect to the motherboard and some do?

So if your card uses the spdif then you don't see a HDMI option in the sound preferences to pick? Because all I see is the Realtek HD Audio...

Also with a card that uses the spdif, where is the HDMI audio support coming from, Realtek or Nvidia driver?

I've been playing with some different drivers, some I can get some sound but it has some static and it cuts in and out, and some other drivers nothing, also I changed my HDMI cable, that didn't do anything either...

Any help would be greatly appreciated...

These are the drivers I've tried so far;

266.58
260.99
197.45
195.62

THANKS

P.S. Between ATI & Nvidia, does one offer better HDMI support?

The audio comes from the Realtek chip and driver. Just make sure the SPDIF is enabled and not muted in the Realtek drivers and/or Windows sound manager.

Well in the Realtek panel the Output Digital Audio source is checked...

Digital Out in the Volume controls is greyed out, not sure if this is what I need here...

I've tried many things and I just can't get decent audio...

Well have you tried various Realtek drivers? Other than that I can't think of any quick troubleshooting ideas.

Perhaps the card, the little cable, or the Realtek chipset is faulty.

I think the simplest solution in this case would be to replace the video card for one that has an audio chip built-in. All Radeon HD cards have it, and newer Geforce cards have it, so you won't need to use SPDIF.

Are you getting audio AT ALL or just not 5.1 surround encoded audio, i.e. are you getting a stereo feed out of the HDMI video cable?

I assume you have the HDMI cable connected to either a receiver or directly to the television?

Does your motherboard have either a coaxial SPDIF or optical TOSLINK connector onboard?
