I just got a new graphics card for a media center I built with an HDMI port on it. Of course the only way to get sound through this HDMI port is to connect the SPDIF cable from the motherboard to the card. Problem is I don't have an SPDIF cable on my motherboard.
My question is would it be possible to purchase or make a cable that goes from my Line Out in the back of the PC to the SPDIF in on my graphics card so I can use HDMI for video and sound?
Yeah, and even the sound card method you need to make sure that you have the proper header and cable to connect to the graphics input.
It's still a good idea to add it, since it wasn't there before, but unfortunately we get stuck with these situations.
It would be nice if someone like Auzentech had a card similar to the HomeTheatre in a PCI version (don't think it would be half-height though).
You can look for an audio card with an electrical SPDIF output, which are a little rare in findint the appropriate jack to jack for the graphics card input, but for now you might need to connect the strereo out to either a line-in on your TV or a seperate speaker setup. Kinda sucks, I know.
