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.

P.S.3 With that settings you will get ONLY ONE crackling sound... at Windows login screen just after power booting your laptop... 🙂
P.S.4 I have Rog Audio Wizard (Maxx Audio) set to Action profile at its default settings.

Nice find Sanctrum! It worked for me without changing the registry. I have enabled 1 right now so likely the registry doesn't matter in the workaround(likely because Realtek doesn't seem to care about any changes in the registry). Only thing that sucks about the workaround is when you actually want to use the microphone for Skype let's say then you have to go and undo everything.

I think this shows that all we need is for the driver to be fixed so that we can turn off the damn power save. I have zero issue with it crackling once at windows login screen (which is what it did with the workaround). So Dear Asus.....fix the Realtek drivers so we can turn off power saving!

Sactrum, nice hack forcing the audio flow to keep the amp on all the time 🙂

Mousepad, the question is, what would the driver fix look like?

How about a button to disable/enable Power Saving be brought out somewhere in the UI? Or, more directly, a button that enables the Power amp to be on all the time?

I wonder why that hasn't happened after all these years of tweaking things to stop the powersaving side effects?

Marshall, can Asus please put in this request to Realtek ??

From what I have read on forums there used to be a box you could tick in older Realtek drivers to disable power saving. So that would be the easiest solution? Otherwise maybe a way so that the registry settings changes actually work? Right now it seems, at least on mine, that no matter what I put in there that Realtek doesn't respond at all to the changes.

I fixed my crackling issue first by activating the microphone permanently and muting it, and then a couple days later by installing the newest Realtek drivers and doing the registry edit for power management. All good now.

Pisses me off that Asus hasn't responded to this yet..

This is still NOT Fixed...NOT REALLY! Again, these...adjustments...you might say merely hide the fact the issue is there...and do not really correct the problem but merely put a Band-Aid on it.

Also, if you listen really closely...and pay attention...it may need to be absolutely quiet for you to hear...but you will still hear distortion/popping...etc...

Also, many of us are having the issue of the left side speaker being slightly louder than the right.

So, in summing it all up...there really is as of yet no permanent fix...only setting adjustments and minor corrections to simply smother or mute the issues.

Sorry : (

Sanctrum uncheck listen to this device and then recheck it and when the sound card is "on" there is like white noise/shhhhh sound even on mute. It's like you can hear that the speakers are on? Do you hear it?

[Sanctrum]

Yes I can hear it... but it has very low volume.
P.S. In fact... you can hear it ALSO when the "listen to" is unchecked... but in that case it is when audio is played and just ends when crackling is heard - as audio card gets powered off.

So in case of Realtek driver... White noise = audio card powered.
I didn't have any strength now to test it using standard Windows driver.

I am working on another workaround. Keep the fingers crossed... as it looks promising but requires compatibility/stress testing that needs some time.

Make sure to send Asus an hourly bill after!! 😄
