Hi,
I am playing with different options to get better sound out of my HTPC
Everything is onbard an hdmi equipped Asus m/b, I am generally satisfied by the video output but the soundis a big no-no; horrible static through hdmi (a major flaw of this board)
For now, I have installed a dedicated sound card (I had laying around) with optical audio out to my receiver, its ok but only a temporary solution as far as i'm concerned

I could replace the m/b altogether with another hdmi equipped without any reported issues, but while looking for computer components deals, I might have came across a simpler solution
If I install a dedicated video card with hdmi connection, I might get decent sound of it, as opposed to sound from my flawed m/b

So my question is: If I just pop-in this hdmi fitted video card in there, should I get any sound out of it "automatically"?
I mean, is the videocard pci-e connection to m/b sufficient to grab the audio from the computer, or do I need some sort of additionnal connection to do that?

Hopefully my question makes sense to you

My setup:
TV: Samsung plasma 59" pn59d550, DVR: Cisco 8642HD, HTPC: Acer Aspire E1-570,
Peachtree audio DAC-iT, Logitech Harmony 650 remote, Logitech MediaBoard Pro Bluetooth k/b
Receiver: Harman Kardon HK 3490, Speakers: Mission m34i + Mission MS10 sub, Nexus 7 2nd gen

Yes, a modern video card has audio on the HDMI output. You do have to choose the video cards audio output in "Play back devices" in Windows 7.

OK, then, the next question is:
could those horrible statics I was getting with the m/b's hdmi ouput come out just the same out of the separate video card as well?

Do I need to try it to know for sure; it would suck to buy & install it & endup back at square one, as the store should replace an opened packaged "doa" but I doubt they would refund

For now, I have optical out from a SB X-Fi & sound output is clean

I've never gotten any static or noise from the HDMI output of the various AMD video cards I've had. I currently have an Asus motherboard. My advice is to get a AMD HD7xxx series card.

All is well, sound coming through hdmi, I coudn't get a hd7xxx as it required pci x 3.0, and my lowly board only supports 2.0
Still very happy to have this working the way I want to, so thanks for your help
