So I've got a new desktop pre-built from CyberPowerPC (Like 2 weeks ago) running Windows 8.1. And so there's been Audio crackling when I'm playing music on ITunes, Spotify, Youtube, etc. But I noticed when I would run a game (BF4, BF3, GTA IV, etc. it would stop and so I did some tests and so I started playing some music (Crackly at this point) and then started up Minecraft and watched the CPU Performance and noticed that if it went above like 12-15% it would go crystal clear but as soon as I quit MC or any other game or program it would go crackly again.

Here the Specs:

Intel i7-4820k 3.7 GHz

Gigabyte X79-UP4

EVGA GTX 770 ACX 2gb

2TB SATA III 6GB/s 7200 rpm

Realtek Audio - Version & Onboard 7.1 Sound

Could be your speakers or headphones, I would get a cheap USB soundcard and see if that fixes it. If it does, you can continue using that, return the motherboard, or get a nicer internal soundcard. That will work for testing it, might even be better than onboard.

Sounds like its either the Sound Drivers or the Sound Codecs. Try installing a Codec pack such as Klite. Download the Standard Pack. Make sure you select the audio codecs during the installation. See if that helps.

For the drivers, update to the latest here.

The order I would follow (assuming you've tested the speakers, with another device, and unplugged/replugged the speaker wires leading to the sound card):

1. Update drivers, test.
If fail
2. Download Codecs, test.
If fail
3. Install another Sound card (if you have one)
4. Reinstall Windows
If fail
5. It's the Motherboard. Contact your motherboard manufacturer for warranty details (RMA).
