Hello. I built my first PC for Christmas. Everything went fine however I get the weird this distortion I didn't really mind it the beginning but it is now starting to irritate me. I sometimes listen to songs with no distortion at all and then songs with a lot. I notice the distortion the most when I close a window, change tab/window, open new tabs/windows. I don't have a sound card or dac. I connect my headphones with USB. I have tried both the top USB slots and the ones at the back of the case. And the headphones are not the problem I've tried others too. Thanks in advance.
The audio distortion sounds a but like this:
My specs:
-Z97 MSI Gaming 5
-MSI GeForce GTX 970
-8GB RAM
-Intel i7-4790K
