Buzzing coming from speakers. But just from one pair of speakers...

I just built an $1800 Gaming rig a few days ago. I'll spare most of the details, but I'm running an MSI Z87-G45 Gaming board, (which runs an on-board Creative Sound Blaster Cinema Sound Card), and an MSI GTX 780 Gaming Graphics Card. All inside a Corsair 750D.

The reason I only posted those specs are because I'm having an issue with my *older * Logitech Z506 5.1 speaker set up which is plugged into three of the six back audio ports. Whenever I play any kind of game, i.e. Minecraft. I get this horrible buzzing, static noise from my speakers, which is very loud if I go past 30% volume. Even if I select some text in chrome, there is this audible buzz.

I've read countless forums saying it could be the graphics card, or the fans vibrating against the case, (My case runs 5 Corsair AF120 Performance fans, but they have rubber grommets on them so I don't think it could be them) or that the sound card is bad, etc. And I've played around with all of those suggestions, fiddled around with the sound blaster setting, upping the bit quality on the realtek HD audio drivers (from say 24 bit-44100hz to 24 bit-192000hz) and nothing has worked for me.

Until I tried unplugging my speakers from the back of my motherboard and plugged in my skullcandy crushers into the back port while playing a game (minecraft). And bam, no buzz at all.Zero buzz. Then I tried the front audio port, same thing; no buzz. THEN I tried plugging in only the green plug from my speakers into that front audio port, and the buzzing was even worse! So after that, to really make sure I was right. I took an audio cable from my Logitech Z623 2.1 Speakers that I use for my Xbox One and TV, and plugged that cable into the front audio port. And again, crystal clear audio signal even cranking the Z623s up to 100% volume. (for a short time of course) I couldn't try the back ports because the cable couldn't reach and I didn't feel like dismantling my whole setup to try it, since I think the problem might be that my old speakers are going bad.

But I hope to get some info from the community just to confirm if my suspicions are true.

Hope to get some help soon!
