Audio gets bad static when XMP enabled

I'm running:

5600x
B550I Aorus Pro AX
2 x 8gb Ripjaw V, 3600mhz CL16 (I believe this kit specifically)
Corsair SF600 PSU

I'm been tinkering / running benchmarks / fooling around after upgrading my CPU, GPU, and motherboard over the past week or so, and have left XMP disabled for a while out of pure laziness. This evening I decided to go back and enable the XMP settings for my RAM, and then I noticed that the audio being passed through to my display (via displayport) and sent to my headphones (via Logitech's proprietary dongle for G933s, I believe) had quite a bit of static. I tried updating my sound drivers through Gigabyte's website, and that didn't remedy the issue.

Then I thought that perhaps it was the XMP settings for something, and when I went back to turn that off mostly resolved to my ears. Anyone have any idea why, or what part in particular is causing the issue? I think I'm outside of the Microcenter return window for the motherboard, but this sounds more like a warranty issue and not a simple return.

Any tests I should run?

EDIT: Oh, and I should add that when I enable XMP on this system it causes my Cinebench R23 scores to go lower. Basically I was getting the best scores on a clean install (with just the stock cooler) with PBO enabled and XMP turned off.

Stock, I get 10879 MC / 1533 SC.

PBO enabled, I get 11510 MC / 1542 SC.

XMP enabled, I get 10689 MC / 1533 SC.

PBO + XMP enabled, I get 11350 MC / 1532 SC.

That's why I've been leaving XMP off for a while.

Perhaps that issue is related to the audio distortion? Doesn't seem right to me given how much Ryzen loves fast RAM. Maybe the RAM just sucks?
