G751 Sound Crackling Thread (The one thread to rule them all)

[Mousepad]

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 username : spcust password : hwwk758z
What this means is that you need to do this in regedit : Using : [HKEY_CURRENT_USER\Software\Realtek\Audio\RtkNGUI64 \PowerMgnt]
"Enabled"=dword:00000000

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!
/EDIT

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.

Didn't work on My G751JT win 8.1. ( but I have used old driver)
I think that marshall doesn't read these posts.

To Asus,

After purchasing a new G751 laptop within 24 hours I started getting the crackling noises which appear to be random more or less. The sound comes from the left lower speaker area. They respond to me when I click on something usually. However even when I startup the laptop they also randomly popup.

During normal computer usage I get the popping about once every 30 seconds or when I click on a youtube link I always hear it.

I updated the latest Realtek drivers [ dated 22/10/2015] as of now. This only made the crackling noise more frequent. I was using the pre-installed Realtek drivers before this, dating from June.

This is very bothersome. Because even when I mute the sound. The popping doesn't end. I didn't expect to have such problems on a premium machine.

@ Jarinha ... What was your findings???

didnt work on my laptop. I believe mine is caused by bad shipping or packaging. my sister bought my laptop without issues and ship it via dhl. i received and checked, and theres this popping sound while playing any music from the subwoofer. Another probable reason is static problem. the very first time I touch my laptop out of the box, it gives me some kind of a static.

update from my laptop crackling problem:

I have crackling problem whenever I play any thing that produce sound on my laptop subwoofer and I have done everything from different website but I failed and still has crackling issue. I messaged asus and recommend to visit my local asus service center.

PROBLEM SOLVED! First they replace the subwoofer speaker under my laptop but still has crackling popping issue. they order another laptop motherboard and replace my older motherboard. POPPING SOUND IS GONE!

Even the driver fix only fixes realtek power management issue but it doesn't take away the crackling sound. It only reduces the amount of times that it happens to once in the beginning of windows. It likely does make sense now to see that there likely is some kind of defect in the hardware given sound still crackles upon "opening" the sound.

[ghunter323]

go to your asus service center and replace your motherboard while warranty is still there. my laptop is under warranty and I pay nothing for the fix and replacement

[ReeveJ]

I'm still not convinced that its a hardware problem. Why would removing the driver and using the default Windows one fix the issue?

I'd like to try this new driver, but is it official? How come the only one I can find elsewhere is the February, 2015 release?
