I have a strix raid dlx sound card. In hindsight, it looks like I should have went with an external solution, but I have it now so that's that. It seems to have a lot of background noise when the gpu is under a high load. I'm nearly sure, that when I had the same sound card in a asrock z77 gaming 6 motherboard there was no buzzing or anything like that (I remember I tested it when I bought it and was impressed at how there is no background noise). Now it's running in a msi x99 gaming 7, psu is evga 850w g2, gpu is 1080ti fe. Any ideas? Any fixes or should I try to sell it? The onboard sound works fine, but after spending quite a bit of money on the sound card I would like to use it. Also, it's much louder than the onboard sound.
