EDIT - These drivers seem to allow us to disable Realtek power management ftp://ftp3.realtek.com.tw/Realtek/GeneralRelease/7624_PG435_Win10_Win8.1_Win8_Win7_WHQL.zip

What this means is that you need to do this in regedit : Using : [HKEY_CURRENT_USER\Software\Realtek\Audio\RtkNGUI64 \PowerMgnt]
Make sure to restart after you change regedit. What all of this will do is when you turn on your laptop the first sound in windows will still produce a crackle as the sound turns on but then the sound stays on and doesn't constantly crackle every time there is a sound. There is still a shhh/chhh noise if you press your ear to the upper left part of the laptop. However, this noise isn't as noticeable as the crackling was and you have to actually press your ear against it to hear it.
Credit goes to X7007 for trying out these drivers first. Good job!
We seem to be spread out on too many threads with this issue and some people aren't even aware of other threads where this issue gets talked about so I figured a more centralized thread where we can see how many people still have this issue is warranted. If you still have this issue and the Regedit fix doesn't work for you please just make a small post here.
Video of the issue - https://www.youtube.com/watch?v=a0q5Fa-lZr4 https://www.youtube.com/watch?v=j0KjGZNRur4
When making a video of the issue it is harder to hear than in reality. I don't have to put my ear next to the computer like I put the camera to hear the crackle. That's not how I computer. I just go to youtube.com and before I even click a video or play audio it crackles. Every. Time. It prematurely crackles. Putting the volume on mute doesn't make it go away. Making the volume louder or quieter doesn't either likely because it crackles before the audio even starts playing. It anticipates the audio. Another easy way to hear the crackle is to go into the Realtek application with the volume on mute and click on the speakers and they do their test but as you click on them they crackle and when the 2 second test is over they crackle again. You can also open up a video and it will crackle. Open up a video and close it right after is also fun for double the crackle. Almost like something turning on and off except I doubt you are supposed to hear it. My HP HDX18 never made this noise. Another thing to note is that this crackling issue has threads for other laptop manufacturers so we all think given the evidence that this is driver based. If I uninstall the Realtek drivers the issue goes away but then the sound sucks and I'm not really getting what I paid for!
One last thing to mention is that I am currently talking to CL-Albert about this issue so hopefully we can come to some conclusion. His test unit makes the crackle very minimally to the point where to hear it he has to put his ear to the laptop. So it is different than ours.
