This motherboard dont have SPDIF internal output. So i cant send digital audio via HDMI. But if i connect PC audio Out and TV audio IN(RGB/DVI), then
i hear only silence. I connect my laptop via VGA, and headphones out to TV audioIN (with same audio cable), sound works fine.
So i guess, if connection is DVI-HDMI, then TV automaticaly switch to analog audio. Maybe is a way to make it switch to analog with HDMI-HDMI ?
OK, sorry to belabor this point, but I'm looking at your motherboard manual, and it DOES show SPDIF IN/OUT on the rear panel. Now granted, the manual covers three variations of your motherboard (basic/ultra/pro), but the manual specifically points out what features are/aren't available on each model. The manual does not exclude SPDIF from any/all of the models, so it should be there on your motherboard.
See here: http://download.gigabyte.ru/manual/m...a%29-sli_e.pdf
Go to page 22 of 88. It's a diagram of the back panel. You'll see the SPDIF IN/OUT connectors there.
However, that's only part of the answer. Your problem is that I don't see actual SPDIF pins
on the motherboard; just the actual RCA-type jacks on the back. So, in order for you to use SPDIF through your video card, you would need an adapter cable.
Take a look at this "CA-1" cable here...it's RCA (male) on one end, and a 2-pin connector on the other end:http://www.htomega.com/cables.html
This looks to me what you would need. You would connect the RCA male end to the SPDIF OUT on the back of your PC and then (carefully) thread the other end of the cable inside your computer case and connect the 2-pin connector to your video card's input.
Now, I can't tell if the 2-pin connector is exactly the same size as the connector you would need to fit the video card, but I'm going to assume you have the original SPDIF cable that came with the video card. You should be able to make a "Do it yourself" cable with the proper connector (connecting to the correct wires, of course) from the cable you already have. But who knows? Maybe the connector that comes with the CA-1 cable I linked to would fit the video card just fine.
Anyway, the bottom line is that your motherboard should
already have SPDIF capability, if the manual I'm looking at is accurate.
Edit: After typing all of that, I saw that you did say you didn't have "internal" SPDIF, so I guess you already know about the external SPDIF. What I would do is write to the people who make the adapter cable (HT Omega) at email@example.com
. Explain to them that you have a 9800GT video card, and while this cable was made for their own products, maybe they could tell you before you bought it whether the 2-pin connector side would fit into your video card ok.
