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.

Is anyone with a g751 NOT having this sound crackle issue?

[lazybuoy]

I returned my laptop. I will wait for asus to issue a proper fix. Or I'll go with another brand. I have always been a fan of asus. Three asus laptops within the family so this is definitely a blow to their company's reputation.

To be fair, this crackle is the only issue that I have with mine. The laptop is generally great. Our issue is also a driver problem, so there's not much point in returning the unit unless you have one of the documented hardware problems. To illustrate my point: uninstall the driver (RealtekHD Audio) and restart Windows. The default driver will install automatically. Listen close. No crackle. Assuming that you aren't experiencing any other problems, I would only recommend returning the unit if you plan to purchase another model or brand.

Yes, that was the only issue left to solve for my laptop too before I returned it. I really didn't want to let it go. But I've read a lot of forums on realtek drivers and even some windows 7 users still suffer from "crackling sounds" on their PC's cuz of realtek. They didn't solve anything for some people. In the end, it was up to the individuals to solve their own sound issues. One of the guys even resorted to using an old realtek driver to solve his crackle problem in windows 7 and in doing so, helped others with the same issue/similar PC's. Being that we basically tried everything to solve the issue ourselves, I wouldn't count on realtek to issue a driver to solve this. In other words, I wouldn't gamble $2000 (the cost of the laptop) on it. How hard is it for Asus to come online and take responsibility for the sound issue? Not very hard. Why should consumers settle for a defective laptop brand new straight out of the box? Within an hour of using my brand new G751, I was already on the forums trying to fix the sound. Absurd. :mad: (and I understand some people have been waiting months for an official fix, yet no word from Asus)

Windows 7 lol

Just to keep this thread going my response from Asus support email was factory reset or RMA. I'd do a factory reset if I knew it would definitely fix the issue.

Factory reset as in reinstalling the Asus Windows image that came with computer? If so, don't bother as it won't work. I've tried it and I think others have too to no avail.

I also have gotten the same response from customer service and tried the factory reset. It does not solve the problem and isn't worth the extra work.

I've got a ticket open with customer service right now where I'm trying to convince them that it's a driver issue. Probably they will suggest RMA again. As I've said before through, RMA is will not solve the problem and you really don't want anybody poking around in your system unless it's really necessary. I suggest that we all contact technical support at the same time because most of what I get from them is that 'we're not familiar with this problem' (i.e. 'sorry, doesn't exist - did you try installing the latest drivers?').

On a side note, their demo model g751jm also had the crackle sound.

Is this issue not still happening to everyone? I see the sticky with a supposed fix on the main forum page, is that not a full fix?

I haven't used my built in speakers enough yet to notice it
