i have:

evga 750i ftw.
evga 9800gx2
samsung 2693hm

if i used dvi, no problems.
if i use hdmi, i get random noise. i can't make any sense of it.
 
Which cable did you buy?
How long is the cable?
Does the same thing happen using both gfx ports?
Have you tried another cable?
Does the cable operate ok on other machines?
 
If DVI is an option always use DVI. Nvidia's HDMI support is not that great right now, but probably because they see it as I do -- a non feature for PC users. Use separate cables for audio and video, and boom, no more problem.
 
I have used ATI's HDMi adapter and connected DVI >HDMI Adapter > HDMI cable > TV.

With the HDMI adapter I found text was fuzzy and the picture in general had extra noise. Audio was well transferred (no clicks or pops) to the TV, but the visuals were degraded enough over 1080p that it was very noticeable and no tweaking on sharpness with the TV could repair this.

I bring this up as it is not just an nVidia problem. Using a straight DVI to HDMI cable produced no visible signal corruption with ATI HD 3870/3870x2 for me.

Import, have you tried a DVI > HDMI cable, and switched from port 1 to 2 at all? Sometimes the first port works better, sometimes not. I used the Samsung 2493HM HDMI input with DVI > HDMI with no issues as well, and it's the same electronics. Using the aforementioned method with the ATI card produced some noise and signal corruption, worse on port 1 vs. port 2.

No noise over DVI because DVI doesn't carry audio. Noise over HDMI because HDMI does carry audio.

If you don't need the display to receive audio, go with DVI.
 
rofl, i meant noise, as in actual sound.
sorry, im retarted.
 
The 9800GX2 doesnt support audio via HDMI but as HDMI audio is digital only, no signal should give no sound at all so I dont think that is the cause.
This makes me think that your monitor is using another audio input when using HDMI.
Try selecting a different audio input on your monitor when using HDMI (if possible).
 
no dice.

all i have plugged in is the hdmi cable and the power. the sound still persists. its just a crackling/popping over the speakers.
nothing in the options.
 
Plug the PC and monitor onto a 2 or 4 way adapter so they are both running off the same wall socket.
Try different mains sockets.
Its possible there is an earth/grounding problem.

If not, lets look at the NVidia card.
Can you try it on a friends HDMI setup or can you get a similar NVidia card to test?
 
i got it.
i had to run the little 2 wire plug from the 9800gx2 to the spdif pins on the motherboard.
apparently no single doesn't equal no sound.

and now, i can have sound from the monitor AND the razer barracudas. awesome. that is exactly what i wanted.
