SPDIF input for audio over HDMI?

I want to have the ability to directly hook my computer up to the TV over HDMI.

My video card has the ability to do this by way of an SPDIF input cable. The problem is, I can’t seem to find the appropriate output on my motherboard (using onboard sound).

It’s only 2 wires… one being a ground.

any ideas on how to get this working? I image that any audio source would work… can anyone verify that? So, instead of using the specific SPDIF out, can I just use headphone out as long as the ground is attached to the appropriate place?

ideas? I don’t have room for a 3rd party PCI card

Or if you want to look at the manual, the mobo is a DFI Bloodiron p35 T2RL. I looked through the manual like 3 times looking for something on this but didn’t see anything.

You want something like this

Only you obviously don’t want to spend 300 dollars…

Maybe monoprice has a similar device for 30 bucks…

thanks for the heads up justin. That looks like it would work, but my video card is supposed to support it OOTB

it has a port on it like this

I just need an audio out source from the mobo to hook it up to, so audio is carried over the HDMI cable as well as video (only video is being sent at the moment)

dvi to HDMI

S/PDIF is used for Audio signals BTW not video…

no, I’m running HDMI from my video card already. The 2 wire cable from that picture I posted is a SPDIF connector that enables it to carry audio over the HDMI cable along with the video signal, the problem is that I cannot find a side by side 2 pin audio out on my motherboard.

Either I’m missing it or don’t have one in which case I’m wondering if I can just use the headphone pins on the motherboard to do the same thing. As long as I know which the ground is, but I don’t want to damage anything either

ok so basically you don’t have a SPDIF on your mobo?

7

more or less

it has coax and optical out, just cant find an aux output on the mobo anywhere

I don’t know how to do it but your post is confusing…

You are trying to find an internal spdif connection from your motherboard to your videocard so it can be combined onto the hdmi out from your video card?

yup

edit: yeah, looking back that isn’t very clear

10

I’m not entirely sure though…can you go 1/8" out of the soundcard to RCA into the TV?

11

you are going to end up in a pool of solder

12

no :\ TV wont accept 2 audio in sources. If I switch to RCA or S-Video, it should work fine though, but would really prefer HDMI

you are going to end up in a pool of solder

yeah, you’re probably right. Have you ever done this before? I have an ice cold beer with your name on it if you know how to get it working, neighbor :smiley:

What motherboard?

14

Not too sure ur gonna get hd audio through it w/ that motherboard. but you can try wiring the gfx card to the front audio header between PCIE3 and PCI1. it’ll be analog line out which may or may not work. but worth a shot. otherwise, if your good with solder, try and splice into the optical out.

pretty sure my hd sound card supports my gtx260oc… havnt looked yet. but u’ll probably just have to get a new sound card. if your onboard card sucks… your framerate takes a plunge in games
