I'll paste this text i've posted in a couple of forums.
This is really bugging me because on top of everything i'm getting a weird, rhytmic clicking sound on my daw. This is really weird because it goes away if i change from Asio to the default device, and it comes right back after a while.

My sound quality has spontaneously turned into crap within a day and i have no clue why. I have noticed that there's high frequency static when audio is played. Also there's crackling sounds. especially when i turn a volume knob, a crackling sound appears (In a youtube video for example). And also the general quality of sound seems to be lower.
I've tried tons of things to fix this. First of all, i think it's related to my MB. The problem is the same with different headphones, and it persists when i change my output from my external soundcard to my MB's integrated soundcard.
I've tried updating my drivers (GPU, CPU, MB, Chipset, Sound card, Bios) I've also tried enabling/disabling onboard sound in bios and increasing the PCI Latency in bios (to 96). Changing my audio's sample rates and bit depths hasn't helped either.
My hardware:
MB: Asrock P43Twins1600
CPU: Intel E7300
GPU: Raden HD 4830
Soundcard: SB Audigy
OS: Windows 7 32bit
Any help would be appreciated
