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.

Hassan turning off power management is done by Loading Regedit, going to 'Computer\HKEY_CURRENT_USER\Software\Realtek\Audio\RtkNGUI64\PowerMgnt' And setting ENABLED from 0 to 1. It dosent do a thing for me unfortunately.

However, i just threw together an infinitesimally small Wav file of practically zero size and no data whatsoever in it and have this tiny little program called TinyPlay playing on a loop as an invisible background service that runs on startup and now have completely cured the pops. I would much prefer a more elegant solution tho.

Currently looking into making the windows startup sound play the wav i have, which is easy to do plus windows 10 dosent even use the startup sound as default which is handy but just trying to find if there is a way to make it loop.

You're a star. Thank you for summarising all the possible solutions into that one post, much appreciated.

Unfortunately I am not so computer literate. Are there any 'how-to' guides anywhere I could follow to try these 2 solutions?

I am happy to try a 'not-so-elegant' solution for the time being as it is quite annoying. I hardly use my laptop because of this issue.

If you could clarify exactly how to do it I'd give it a try now.

I really appreciate this!

I thought i was very clever working out this fix so quickly then today found that someone beat me to it long ago lol 😞

https://rog.asus.com/forum/showthread.php?60761-G751-Sound-Crackling-Thread-(The-one-thread-to-rule-...

Im currently looking for a way to play the sound with next to no cpu usage, the fix above works with less cpu usage them my method but it still uses approx 1% when a huge behemoth like windows 10 only uses barely .5% at idle.

However I did not test it at Win10

Hi mate, I just literally had a chance to turn on the laptop today (been sitting idle for 2 months!) and tried your solution.

I went located the PowerMgnt setting and ENABLED was already set to '1'. I decided to go the opposite way and set it to '0'. Was this the correct thing to do or should I leave it at '1' regardless?

I haven't noticed the clicking sound yet but will keep an ear out to see if it has either disappeared or at least improved.

Many Thanks,
Hassan

Albert you mentioned that you have a fresh install. I wonder if anyone has tried reformatting with a fresh install to see if that randomly fixes it?

Actually, just wanted to clarify that I still did a recovery with the ASUS image, but it was not with the original factory image and was a (slightly?) updated ASUS factory image if it matters.

If anybody can just check this issue after doing a reset/recovery with their factory image before installing anything else (anti-virus, etc.), it should probably be good enough to eliminate any software issues.
You might also want to install the latest drivers from the ASUS download site, but I didn't notice many that seemed like they would be related to this.

Since I'm running the 206 bios, we may want to compare bios versions as well and I can try to downgrade my bios version too if necessary. Thanks.

I have tried the newer one and I thought it made the issue worse. Has anyone else given it a shot?

I am running the windows install that came with the computer and I just took off the bloatware. Albert you mentioned that you have a fresh install. I wonder if anyone has tried reformatting with a fresh install to see if that randomly fixes it?

Mousepad, the new 7443 made the sound louder?, longer?, worse in what way?

Also, keep the Asus Windows build, that is what Asus uses to recreate problems - it's their OS, so why would they do a from scratch Microsoft Media install? 🙂

It is tough for Asus to recreate a problem reported from a non-Asus Windows install. Keeping everyone at the same image is important when debugging.

EDIT - I re-installed 7443 to try the Regedit fix thinking that, hey new driver maybe I can disable power management now. It didn't work. It did give me another chance with the drivers and the crackle is the same. It did crackle while I was in regedit though which was weird. I still think this comes down to the Realtek power management and for whatever reason we can't shut it off. There used to be a box you could uncheck in the software to disable it but it is not there anymore.

I really have zero idea of what you are talking about with the whole Asus Windows build? I was mentioning this because Albert said he had a new windows install so I was curious if others had the Windows that came pre-installed or a new install. I asked this to find a link between us as we seem to share a problem and yet no common link besides owning G751's but others also share that link and the crackling is minimal for them....Why is the crackling only loud for some of us? Why do other notebook manufacturers have this crackling issue but for most people the Regedit PowerMGMT fix works but for us it doesn't?

I will try to contact the repair center where I am at on Monday but unfortunately I am not in the U.S. right now so I will have to see how it goes. Will report back on what they say. Hoping they speak English!

Mousepad, the Asus Windows Build image is the Windows installed on the Computer when you take it out of the box. It is also the recovery image on the recovery partition. The F9 reset or Asus Backtracker recovery flash drive both install that same original Asus Windows Build image.

What you said suggested that you thought cl-albert had done a From Scratch Microsoft Windows Install, and he did not do that - I wouldn't expect Asus to use any other Windows install than their own.

Albert did an F9 reset to restore a "clean" version of the Asus Windows Build image onto his test laptop - so he could start with a laptop at a known good configuration.

When you said "Albert you mentioned that you have a fresh install. I wonder if anyone has tried reformatting with a fresh install to see if that randomly fixes it? "

I thought you were alluding to trying a From Scratch Microsoft Windows install yourself, and I was trying to get you to stop 🙂

A "clean install" of Windows is not a From Scratch Microsoft Windows install, that is a starting from scratch waste of time. You need to do so many things to get that from scratch Windows install to the same point as the Asus Windows Build, I was trying to save you the time of going down that path.

Also, that from scratch install will never be the same as what Asus ships, and therefore won't be re-creatable at Asus to test your problems. It may be close, but it won't be the same.

Given both you and Asus are running the exact same F9 reset "Clean" version of Asus Windows Build image, you can both be assured you are testing on the same base configuration.

Thanks for working with Albert, please keep us updated as to how it goes 🙂

cl-albert, thank you for focusing the threads to here 🙂

Also, you can try a newer Realtek driver, Version V6.0.1.7443 for Windows 8.1 x64

Glad to see everyone together in one thread!

I have ASUS ROG G751JY should I try this drivers?
