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.

I have ASUS ROG G751JY should I try this drivers?

I wouldn't bother. Apparently our problem is still yet to be fixed. It's also been said the newer drivers actually make the problem worse. I sort of doubt that, but I'm not updating until someone reports a fix.

I'll be the guinea pig 🙂 installing

update: don't notice any difference the problem remains, I don't find it worst it's the same...

I don't know why we have to have a new, universal thread on this, but anyway, I have the crackling speaker problem, and the crackle that plays before and after a sound. I raised a support ticket with Asus on that issue, the dropped keystroke issue, and booting into a black screen issue. Asus contacted me back and said to take the laptop into a service center. From what I've read, people often get their laptops back worse (roughly opened and re-assembled etc) than when they take them in, so I'm not keen at all.

Hi there. I don't know of I'm in the right place for that but I have a sound issue. Just before playing .mp3 or .avi for example, I can hear a little sound like the audio card is going out sleep mode or something like that. The 2nd issue is that sometimes I can hear the popping Windows sound spam.
My question is : I saw a post from hmscott I think explaining that it can be solve by putting these values in pwrmngt regedit "65536, 1, 1, 0".
Am I correct with that ?
NB: driver version is .7443 (latest actually)

Yes, your first problem is very likely the one described here. The second seems like an issue with Windows.

Navigate in Regedit to 'Computer\HKEY_CURRENT_USER\Software\Realtek\Audio\RtkNGUI64\PowerMgnt,' right-click 'Enabled,' click 'Modify...' then replace the value '1' with '0' and restart your computer. Better yet, hold down the power button until the system shuts down and keep holding the button until the battery light (below the touchpad) flickers off then on again. This will reset your computer's CPU cycle. Boot up the system again and your problem may be solved. Note however this fix has seemed to work mostly for people with other computer models and not for those of us posting in this thread (including myself).

I tried to put Enabled to 0 but the sound is still here. I did a hard shutdown with power button like you said. I have a G751JY. Is that normal that it didn't help ?
Actually I got these values :
10
0
0
0

Actually guys, the setting of 1 is correct. It is an Enable to Disable Realtek power management while on AC, and it has defaulted to the desired setting for a long time. 🙂

Setting it to 0 reverses this, and turns on Power Management while plugged in... so I would restore the original default setting back to 1.

The symptom when it was defaulting to 0, allowing Power Management on for AC and Battery, was that after sound stopped - about 30 seconds later there would be a pop as power saving kicked in and then random crackling noises as the amp was "turned off" and no longer under positive control.

What you guys are hearing, a noise at the open and close of the audio access for apps isn't related.

hmscott, thanks for explanation. Do you still recommend to set values on 65536,1,1,0 in regedit like you did in an other thread ?

Additional question : Is it OK to set ROG AudioWizard to OFF or I should completely uninstall it ? Actual driver is .7443.

I keep audiowizard on with the multimedia setting as well as maxxvolume/leveler as I think that sounds better but YMMV.

I called Asus and the guy said they are not aware of this problem and to RMA. 10-15 business day turnaround on that here it seems. I think I was talking to a customer service rep and so it is the same response as we got when filing technical inquiries that don't seem to reach the right people so that our issue can be seen. I'm not too keen on RMA'ing for what seems to be a driver issue. Most of us with this issue only seem to have this one issue. Was there anyone else who has other issues along with this one that is sending theirs and that way they can figure it out off of that machine that needs to go anyway?
When I tried to escalate to an engineer or supervisor through the technical inquiry a few days ago this was their response: After consulting related department in TW, up till now, they still have no schedule for next update but we will transfer customers' wishes to them for further development.

I'm going to see what Albert has to say and if he has anything on his end.
