Sudden loss of audio quality

[Random111223]

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

I didn't have a loss of audio quality, but I have an issue with crackling as well, I even sent my computer to the shop and everything. The only way we could replicate it was opening the project file(s) I was working on, and even then, nothing. It's seems to correlate with the CPU usage thingy that FL Studio has, up around 50% it starts to crackle, and it only builds as it continues to play through a song, and idles at 20-30% when all I'm doing is having the project open. I have not been able to correct or get around this issue, doing many of the same things you have.

My external Audio Interface is being shipped to me at the moment, and hopefully using it might resolve some issues. Hopefully.

All I can tell you is that it's your MB sound, which is all the guy at the computer shop could tell me; and I didn't have the money nor want to buy a new MB to fix it; hopefully just using the interface will solve it. Hopefully.

I'm sorry I can't really help you, all I can really say is that I've had a problem similar and there wasn't much of a solution anyone could find.

Oh! Actually, one shred of light we did manage to figure out with the computer guy; he thought it was the pre-amps in my built in MB sound being overheated/overloaded, that might be it. Or it could even be your soundcard, since you actually have one.
