Realtek, Windows 7 64RTM Crackle/static/popping

My sound crackling and popping goes away once I run the GPUZ application.
It is still good after I quit GPUZ. Whatever it does, I have no clue...!!
However, the latency checker continues to give short red lines.
I thought this piece of information might be of use to anyone who is troubleshooting this powermizer issue.

Holy crap, GPU-Z (run once) has solved my problem! Weird. Signed up to post this. Thanks zandorvh.

I have been having this same problem as well. Can't seem to get rid of it, turning Loudness Equalization off in the sound manager seems to help alot. The popping also seems to decrease by a huge amount (its still noticeable just not as loud) If I have a flash video paused on firefox. I honestly think that this is more a windows Issue than anything, seeing as how I get it on my SB Audigy card as well. I just wish I could figure out what exactly is causing it. Any help or ideas on this matter at all is appreciated, but judging by the length of this page I'm not expecting any miracle fixes right now.

I just bought a new HP desktop about a week and a half ago at Best Buy and had the same problem as so many others. The sound would be fine for about an hour and then the static sounds would start. After about two hours I'd have to re-boot. I called HP three times and two times got idiots who didn't speak English. The other time I got someone who did speak English, but he was as clueless as the others. I finally called up Best Buy today and it turns out they have a 14 day no questions asked return policy, so I reformatted the HD and took it over there and exchanged it for a cheaper e-machines that had everything I wanted on it. Surprisingly, my last computer was an e-machines and I got over four good years of constant use out of it. I've been running a web radio on this new one for about nine hours straight now and have not heard a single pop. So if you have a brand new machine and have this problem just take it back to where you got it as soon as you can. It's not worth the trouble to try to fix it.

I have the popping sound driving me nuts on an Acer 7736g. Just brought it over xmas so i sent it back only to be replaced with a new laptop with the same problem.

Dillema... return laptop and ask for full £600 refund because i am not putting up with this for that money or !!!!!!!!!

Just signed up to this forum as i was looking for a solution and didnt realise how wide spread with fault is.

At least i know now it's not me.

I installed the latest drivers from NVidia (195.62) and the sound problem is permanently gone. (No need for GPU-Z)
Yet the DPCLatency still seems to be on the higher end...

Still no joy here.
The sound crackles and stutters when the CPU is busy. That is, when I open a Web page, or start a program, I hear pops and garbled sound if I’m playing music. The problem only happens after the system has been running for a while. A reboot fixes the problem, but then it eventually comes back. This isn't a driver problem (for me), because I have the same cracking sound after trying the onboard sound card AND using different USB sound cards. The problem occurs in any music player (in Windows Media Player, or Winamp).

Here's what I've tried:

Installed the latest drivers.
Tried using 2 different external sound cards.
Installed the Codec lite pack .
Disabled speaker effects (enhancements).
Reset the BIOS to the factory default settings.
Flashed the system BIOS
Twiddled with every imaginable setting in the Sound panel in Windows 7
Turned off Aero to use a basic theme
uninstalled any energy saving software by asus or any software that is made by asus

After trying everything else posted here my solution was to use the latest version of PowerMiser switch. It worked and I no longer have any problems with sound. I hope this helps somebody else.
