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 and distorted. 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 disabling onboard sound in bios and increasing the PCI Latency in bios (to 96) I've tried searching for malware etc, i did find some and my computer is clean now. My hardware: MB: Asrock P43Twins1600 CPU: Intel E7300 GPU: Raden HD 4830 Soundcard: SB Audigy OS: Windows 7 32bit Anyone got any advice? Should i buy new hardware to fix this? Any help would be appreciated.
