GTX280 audio over HDMI

[mkln]

Hi,

I've just today thought about using the DVI-HDMI adapter and S/PDIF cable on my GTX280 and for some reason I cannot get the audio working. I have attached the audio cable from the S/PDIF out on my mobo to the audio port on the GTX280...is there something else I have missed? (I have tried both ports on the back of the vid card)

Does having both ports occupied have anything to do with it?

Any help on this issue is greatly appreciated.

Thanks in advance

You need to change the audio output in your audio cards software, to output via SPDIF.

Here is the setting

That is the only SPDIF that is displayed and it is only to my Z5500 via SPDIF through the rear of the mobo

Try reversing the plug on the motherboard. What board are you using? At work I test on 680i boards, and I've never had to change any audio setting for it to work.

Maybe he has analog PC speakers plugged into the rear and it's autosensing?

Take a look at my thread and let me know if it helps:

I had to change the SPDIF setting in my motherboard BIOS to HDMI
Once I did this a Monitor pic appeared in the audio devices area -- this is what you will want to use.

Thanks for the replies.

it turns out, or it at least seems that way, that I had to turn on an option in the BIOS for PLUG and PLAY...weird.

Thanks again
