Possible DPC lag. Sound cracking/static.

Hello, Im having an issue with sound interference. I have been getting an annoying, loud buzzing sound from my speakers on my monitor When I connect the green AV cables and continues to make the sound regardless if i mute the system. I think it may be DPC latency from what I have seen others post about.

I've tried several things such as: disabled my Mic, moved any phones that were close by away, take out power to the TV and other electronics, but still no help.

I have A VIZIO 32' M320NV. and a Viewsonic Monitor. I'm pretty sure the problem isn't either the TV or monitor because I get the same interference when I connect speakers to the PC.

My Specs for my PC are

Sabertooth x58Mobo
Intel 17 970
1 Geforce GTX 570
16gigs of DDR3 Ram

I have had this issue for a year now. ASUS does nothing for me and refers me nowhere. I have tried everything from RMAing my board, trying different drivers, disabling intel speed step, getting an independent sound card, ect. If someone could please help me figure this out, it would make my life alot easier. It is too much to hear that static come from the monitor whenever I boot something up that requires the system to work (ex) starting an online game up).

Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines belonging to a driver running in your system appear to be executing for too long. Also one or more ISR routines belonging to a driver running in your system appear to be executing for too long. At least one detected problem appears to be network related. You may have to disable wireless adapters to get better results. You might have to disable your battery device to get better results.

Ran another seemed like TCPIP.SYs NTOSKRNL.Exe ACPI.SYS ATAPORT.SYS are causing high DPC Lag. Any way I can remedy this?
 
Ive used several speakers, same thing with all the speakers.

Pretty sure this is a DPC problem. However all the application that are screwing up are associated with Microsoft.
 
Can I possibly buy a new soundcard to remedy this? I remember buying a cheap USB one, and the problem still persisted.

Sound static does NOT go away with nvidia HD audio devices uninstalled and realtek drivers disabled or uninstalled. Even with sound muted you can still hear the static.
 
If the noise persists even with your soundcard disabled and your system muted its probably a grounding problem as cinders said.

If the problem happens with other speakers aswell i would start to look for motherboard grounds, loose cables, cards.

Double check you have the correct drivers.

Hope this helps.
 
And thats the kind of sound I am getting. I am even using the a LatencyMonitor to see if there is DPC latency, and there is. Mostly from ATAPORT.sys and NDIS.SYS. I've updated all the drivers, rewired my PC as recommended, and reseated the mobo. Everything is in place, but I just cant figure out whats causing this. Could it be RAM? Ive tried different GPUs with the same results. The lag seems to subside when I do tasks such as installations and what not.
 
I had the same problem a year ago. Turned out to be the power strip I was using to plug my computer to.
 
I would give it a shot. I bought one with a built in ground. Just for computers. A Little more money but worth it.
 
What devices are located close to your computer? Many times a fan or an electric motor will broadcast a interference that can be heard on speakers.
 
It's a grounding, or electrical interference. You can try to get a insulated cable for the speaker wire, or insulate it yourself using conductive tape an wrap it around the entire cable length. You can also do what cobalt suggested, a better surge protector might help a little, also you might want to try plugging it directly into the wall for cleaner power. Also make sure the mobo is fully seated to the case using standoffs for grounding. I had the same problem with my front headphone ports, it ended up being wireless interference from a nearby wifi card, also cell phone interference is also possible. Just a few things that you might want to try.
