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.

They asked me for proof that the problem is still occurring, what do you guys think is the best method to show our problem?

High quality microphone, high quality video put on youtube, where you can clearly see exactly when the problem is occuring and what laptop model it is. It's best for the camere to be stable.

By the way, the bug occurs even if you mute the speakers! The subwoofer will make a distict noise, before, and after playing the recording, all while the sound is muted by windows. Just start playing something and see(hear) for yourself!

This is really the best way to showcase the problem. You don't even have to play anything. Just open up the volume and click on the slider that you move up and down. Seriously mute or no mute click on the slider without moving it and you will get the noise.

Also I hear there is a thread 18 pages long with a lot of users complaining about said problem and describing it in detail along with multiple videos. You may want to find that thread and link it. Might be hard to find though given even Asus has yet to find it and they are the ones that host it.

Everytime time I use the word forums they answer "we're not responsible for information on the forums..." it's like they don't even want to hear us.

I have installed these drivers ftp://ftp3.realtek.com.tw/Realtek/GeneralRelease/7624_PG435_Win10_Win8.1_Win8_Win7_WHQL.zip username : spcust password : hwwk758z

I then went to realtek power management and put it to enable 0. When I restarted I had volume at 0 and I clicked on volume slider and it crackled but stayed on and hasn't crackled since. It seems that the first sound it plays when you go to windows turns on the sound and now it stays on but you can hear a like constant chhh or shhhh if you put your ear up to the upper left side of computer.

Thus, it seems that we were correct that the drivers were to blame. It's still noteworthy that to turn the sound "on" it has to crackle once and then it keeps a chhhh/shhhh sound the whole time. Anyone know why it makes this sound? It's not really a bother like the crackling was as you can only hear this chhh/sshhhh if you put your ear to it but just curious as to why it would even make this noise?? The noise only starts after it crackles that one time.

EDIT - I have updated the first post with the info regarding this driver and the regedit changes needed. Please try out this driver and let us know if it resolves it for you.

HA!

It's probably the same issue I have during developing the service that was the workaround for the problem.

here: https://rog.asus.com/forum/showthread.php?60761-G751-Sound-Crackling-Thread-(The-one-thread-to-rule-...
cite: "Issue2. Somehow some looping routines introduced SEVERE white noise when MAXX Audio was enabled.
Again, testing and revising the looping routines and preparing better 48kHz silent WAVE files. FIXED"

So maybe they just do the same as me half a year ago... developed a service but they put 44kHz silence wave file... instead of 48kHz that is fixing the problem??? I wonder... 🙂

The results are the same for me.

One more thing, if you can't see the registry location you will need to run C:\Program Files\Realtek\Audio\HDA\RtkNGUI64.exe at least once to get the registry entries showned in the registry. or else they won't be there.
