Man I have searched all over and since Tom's Hardware is the best place to go for answers, I figured I could ask y'all.
I just bought a new HP with a N-Alvorix-RS880-uATX (Alvorix) motherboard. I put in a Gigabyte 9500gt video card in with HDMI output. There is a connection for the sound for the HDMI, but I cannot figure out where to connect it. The plug has 2 separate plug ins that connect to an individual pin each. The sound chip is an integrated ALC888S-VD. I'm not sure how to word this, but it has a pin/chip number 11h with the specs:
Name : SPDIF-OUT2_HDMI
Port : NC
Location : Rear
Device : Speaker
Conn. Type : 1/8" Jack
Color : Black
The location in the diagram for the sound chip shows that this is in location #2, which is the second spot on the bottom (in drawing).
Anyway, I don't know how much of that is relevant, but where can I plug these 2 pin plugs at to get sound for my HDMI? Right now, I have to run an RCA cord from my puter's audio jack to my surround sound system. The biggest problem with this is I have to plug and unplug everytime I want to use it.
It's difficult when we can't see decent images of the board or find a detailed manual. I'm guessing here, but it looks like there are two 2-pin outs on your board just below and to the right of the SATA connection ports. Look on your motherboard to see if either of these are labeled S/PDIF.
Hey thanks for the reply! There is nothing that says s/pdif on the board. Those are jumper pins to reset the BIOS and that kind of thing. I don't know if it's OK to put a link here, but it is from hp's site so it is safe. Mods can remove it if they want, but here is the best info I can find on this motherboard.
Ok. I'm a moron. I saw it and it just didn't register. You cannot use the HDMI audio functionality with that motherboard and that graphics card. It only has one S/PDIF output and that is on the board's rear I/O panel.
Try it with a graphics card that does not require a connection to the motherboard.
OK, cool, I was afraid of that. Unfortunately, I already had this card and don't have much scratch to buy another. Maybe I can rig up a 3.5mm wire somehow. I think that spdif output plug is an optical, isn't it?
The best way to go about it would be to buy yourself a good sound card and connect it's SPDIF out to that card
Make sure if you buy a sound card it has the SPDIF header on the PCB also and not only the Back IO panel.
They're pretty cheap so you can go in for it.
