Sound Card/GPU/MOBO Problem?

[Marts]

Hey guys, I made an account here specifically for this topic, and was reccomended to come here by a friend who said everyone is really helpful.

Basically, I have an ASUS D2X audio card installed in my PC. Until last week sometime, the sound and microphone were all working flawlessly (Logitech G430). I bought a new graphics card last week (STRIX 970) and since then, whenever I enter and start playing a game, there's a real audible buzz on any recording, or any time I speak. I've witnessed it myself through mic monitoring. This isn't my video, but it's exacltly what it's like: https://www.youtube.com/watch?v=i0zuD0c0SRQ.
I've made a video myself, with the speakers plugged into the D2X and the microphone into the motherboard. This was the result: https://www.youtube.com/watch?v=w42RcLp0a94. It's not as bad as the buzz, but the audio quality takes a heck of a hit.

 

I'm really hoping not to get rid of my D2X, despite various people telling me to do so, as I've tried the G430 USB card, and integrated audio and it's just nowhere near the same, for games or music.
I assume it is a problem with the PCI lanes in my motherboard, but I'm not sure. If so, would a new motherboard fix this? I was looking at getting one anyway so I could have more SATA ports avaliable.

Any help would be immensely appreciated!

It could be that you have some EMI going on between the two cards. I would take your graphics card out, and see if that fixes it. I'm assuming that you have the D2X in the x1 PCI slot, and the graphics card in the first x16 slot. If taking it out works, you know that it has something to do with your graphics card, so you could try putting it back into the second x16 slot (assuming your mobo will let you) and see if that keeps the buzz away. Otherwise you might have to try making a custom EMI shield. If that doesn't fix it, your PSU might be introducing some noise when your graphics card draws power for some reason, but I would sincerely doubt that. What cooler are you using? I know that I used to have a phantex (the big two tower design) and with my dual 670s, it caused my sound card to rub on the cooler, so I would always put some paper/thin cardboard between the two, to keep it from shorting, which may also be what's happening.

Cooler for what? CPU? If so, then I'm using the stock one (I know, I know).

This is why we always recommend external solutions over soundcards. Outside of what TeenGeek suggested there's not much you can try to fix the issue.

I'm about to order a new set of headphones, and a modmic. That should fix the problem, right?

I think the "dumb one" meant external audio card

I'd look into an external DAC/amp.

No, the problem is the soundcard picking up EMI from inside the computer. Any headphone plugged into the soundcard will have the same issue as your current headphone. To fix your problem, buy an external DAC/Amp unit (USB soundcard).

@ShearMe is right on this one, A couple of ones that you could get are the Audioquest Dragonfly, or the Schiit Fulla, or one of Fiio's portable Amp/DACs, as they have USB connections. Anything along those lines would work just fine.

Or even a SMSL SD793-II to avoid potential ground loops

That does look like a pretty nice amp, especially for the price...
