View Full Version : G751J Sound Crackling Issue: How to reproduce it, and prevent it. (Yes, I fixed it)

(If there is already another fix for this - perhaps a driver update, please let me know. Otherwise, read on)

So when I first got my G751 (Christmas), I noticed various issues where the sound would start crackling, looked on these forums, and found multiple threads about this issue, with no actual fixes found. I also did a Google search, and found out that MULTIPLE laptops (like, a lot of them) for multiple brands (not just ASUS) have this issue. It is a Realtek driver issue. This issue will happen with all speakers, whether the laptop's build in speakers, headphones, or other external speakers.

So, what is the cause, how do you reproduce it, and, more importantly, how do you fix it?

There are actually 2 different issues. The first one is easy to fix:

Issue #1) The sound card turns off after a certain amount of time of not being in use, and turns back on and "cracks" when a sound is played.

How to reproduce: have no sound playing for like 10-30 seconds. Then play a sound. CRACK.

How to fix:

Sort of follow the instructions in this link. I say "sort of", because the link contains invalid information.

http://forum.notebookreview.com/threads/fix-for-realtek-sound-popping-and-or-high-pitched-tone-squeal.587521/#post7617517

The link says:

"Enabled - enables the power management. Default is 0. Set to 1 to disable and always prevent these noises."

The default is actually 1. You want to set it to 0 to prevent these noises. Here is a screenshot of my registry, which has the noises disabled correctly:

http://i.imgur.com/XbgvY4v.jpg

Also note: our machines do not use "Realtek\RAVCpl64" like the link suggests, they use "Realtek\RtkNGUI64" (or at least mine does).

So with this simple registry edit, this first crackling issue is fixed (and I guess a reboot - make sure to use restart or shift+shutdown, because a regular shutdown in Windows 8 just hibernates the machine, and does not reset the CPU cycle).

----

Issue #2) Your speakers will randomly start making constant, persisting crackling, which will progressively get worse (until it gets to the point where it is crackling like every 5 seconds), and it will continue crackling until you restart or do a shift+shutdown.

Now, for troubleshooting purposes, I am first going to mention the 2 things that I did that did NOT fix the issue. Why? Because I haven't bothered to re-enable these settings, so if you follow my fix (which will follow), and it DOESN'T work, then come back to this part and try doing these 2 things first. And let me know, so I can edit and fix this guide (and will know to never re-enable these settings myself).

1) Followed the instructions in this link to "disable all sound effects" http://corey.degrandchamp.com/2010/11/25/fixed-windows-7-sound-popping-cracking-skipping/

2) In the same Windows "playback devices" menu, I disabled all the speakers I wasn't using, as well as all the "recording devices" (since I don't use them). So my "LG TV", "Realtek Digital Output", "Microphone", and "Stereo Mix" are ALL disabled, leaving only "Speakers" enabled (I use headphones plugged into the audio slot on the laptop).

Okay, so what DID work? What was the cause of the entire issue?

This took me WEEKS to figure out folks. WEEKS. Up until then, I was literally just restarting my machine every 4-6 hours when the crackling would start, to get rid of it.

The cause? *Drumroll*

"GPU Tweak"

Yeah. That thing that tells you which video card optimus is using (intel or geforce), how much your geforce is being overclocked when in use, your fan speeds, etc? That is what causes the issue. If you just let it run in the tray like normal, nothing happens, it does its job, it switches video cards and overclocks like normal, and there are no sound issues. If you have obsessive compulsive disorder, and need to click it to make sure optimus is switching to your geforce video card properly, then BAM, the sound issues will start.

How to reproduce:

Step 1) Right-click this thing in the image below (circled in red), and click "open"

http://i.imgur.com/Uju7zAq.png

Step 2) The following screen will pop up

http://i.imgur.com/7oi2s0z.jpg

CONGRATULATIONS! You will now have sound issues until you reboot your machine.

How to fix (prevent) this issue:

Step 1) Never EVER EVER EVER click the thing in the image below:

http://i.imgur.com/Uju7zAq.png

CONGRATULATIONS! Your laptop will run perfectly fine, with no sound issues, no popping, no crackling. GPU Tweak will run in the background like it always does. You do not need to click it and check up on it. It works. Your games will run fine.

Another thing to note: I do not use the "ASUS Gaming Center". (image below)

http://i.imgur.com/YHJaGEM.png

I DO NOT know if this also triggers the sound crackling issue, as I do not use it, and therefore have not tested it. It has a similar big red ASUS window like GPU tweak does. It even contains a thing that tells you if GPU Tweak is on or off, so it MAY be connected to it. When you are troubleshooting this issue, do NOT open the gaming center. When you have fixed the issue, and are sure it is fixed, feel free to open the gaming center and see if it causes the issue as well. If it does, let me know in this thread so I can properly update this guide, and then NEVER use the gaming center in the future.

You're welcome.

Feel free to spread the word. I'm probably not going to bother looking up those countless other threads and posting this guide in them. At least not for a little while.

Also note: this is not related to the "subwoofer issue" I saw posted on the front page of the forums. Like I said, I use headphones. I have therefore never run into a "subwoofer issue".

Uptime: almost 4 days without rebooting, no sound issues :D

.........brb restarting my computer, because I just opened GPU Tweak to take those screenshots. LOL

I've installed the newest sound drivers (resolving the subwoofer issue) and modified the registry entry under 'Enabled' to '0,' but the crackle just before and after a sound is played continues. I'm certain that it's the Power Management problem, but I'm pretty much at wits end by this point- I've tried just about everything. Also yes, I have tried restarting and powering off the system several times.

Any ideas?

Any ideas?

1) Bios version is up to date ? Latest version is 305. If yes, then try older version like 304 and 303 and see if it works.
2) Chipset driver is up to date ? If not, here is the link https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=20775&lang=eng&ProdId=816.
3) Uninstall all other software like ASUS Gaming center, ASUS GameFirst, and all things you don't actually need.
4) Try also to boot the laptop from a new HDD/SSD with a clean windows install and see if the cracking is still there.
5) If you haven't had this problem form the beginning and it just started after a while, and you say that it is a PowerManagement problem then make a PowerManagement reset by restarting your laptop and when the RoG logo appears press on the power button for 5 to 10 secs until the battery led flashes, turns off and lights up again.

These are the only ideas that I've got at the moment.

ReeveJ, try setting to 1 instead of 0... 0 Disables Disable, and 1 Enables Disable. You are talking about Disabling the Power Saving mode to stop the crackle, right?

falkenjeff, that link has been a reference for years, and it is correct :)

This is true, and has been used by thousands of people over the years since the original posting:
"Enabled - enables the power management. Default is 0. Set to 1 to disable and always prevent these noises."

This is the full list, should that post disappear (NBR is having server issues right now...)

"This can be configured in the registry under HKEY_CURRENT_USER\Software\Realtek\RAVCpl64\PowerM gnt.

The settings there are as follows:
DelayTime - time in seconds of inactivity which triggers powering down the sound chipset. Default is 10.
Enabled - enables the power management. Default is 0. Set to 1 to disable and always prevent these noises.
OnlyBattery - If power management is enabled, setting this to 1 will disable power management when the laptop is plugged in. The popping noises will only be heard when the laptop is on battery power, but this helps conserve power so the battery lasts longer."

Here is how I have my G750JH set right now, I also set the Delay and OnlyBattery as precaution should the driver sense of "Enabled" be changed; at one point long ago this was all in flux, but it hasn't changed since :)

46717

I have no crackling/clicking/popping, at idle or opening/closing audio - it is inaudible if present.

Thanks for the help.

I am running the latest bios version (205). Can you flash an older version? I wasn't aware that was possible. My chipset driver is up to date and I tried reinstalling the one you posted. I'm not running any non-driver Asus software. I also have tried the hard restart like you suggested, both with 'Enabled' set to '0' and '1' under the 'PowerMgnt' key in the registry.

The crackle just before and after a sound is played persists. It's a brief crackle coming from what seems to be the left speaker for about a quarter second even while headphones are plugged in. As far as I can tell this is the exact same problem solved by the OP by editing the Power Management settings in the registry.

Is it possible there's a kind of driver conflict somewhere?

ReeveJ, crackle just before and after a sound, that's different, don't have a fix for that off hand...

You can force an old BIOS install - force using an older dated/versioned BIOS for install by using the command line option /nodate for Winflash, either on the command line or setting it in the properties:

46293

Not sure if that will help. Are you hearing the crackle in speakers, headphones, digital audio out, or all of them?

Is it the subwoofer crackling? Try turning the subwoofer level way down to see if that is it, set to 0 level, then bring up as needed to make it audible but not so high as to make offensive sound:

46294

Is it an overdriven sound like way too loud, or just a static like noise?

I'm note sure that it's a bios thing, either. Nor does it seem to be a subwoofer issue. I've tried changing the volume levels of all the speakers to no effect. In fact the speaker crackles just before and just after a sound is played even when the volume is set to '0.' It comes only from the (left?) speaker even while headphones are plugged in, but not through the actual headphone itself. Always the speaker. It's not really either an overdriven sound or static, it's just a very brief crackle (like a 'pfft' sound) which comes from the left side of the machine immediately before and after any kind of audio input. For example it'll crackle when a video file is opened and then again after it's closed. If you open a video file, set it to pause and then open another type of audio file, there'll be no crackle. You'll hear the crackle again when you close all of the audio files, however. Once again I really think that it's a Power Management issue which I'm unable to deactivate for some reason.

Try the fresh windows test. Just get an HDD/SSD from a friend and install a fresh windows with only the necessary drivers for the laptop to see if it's a software issue or a hardware one. If even with the BIOS changed and a new windows the sound still plays that may be something related to hardware. I dunno, it's pretty weird what's happening to your unit.

I just tried running in Safe Mode and there is of course no crackle. Several weeks ago I installed an older driver version and the crackle never showed up, so I'm convinced that it's not a hardware issue. It could be, but I'm pretty certain that it's a problem with the audio driver. My issue seems to be the same as the first one mentioned by the OP except that it's not being resolved by that fix.

The reg edit fixed my machine, I am on the latest bios and driver revs. Great find on the power saving settings. I keep my external speakers at a high volume level and just adjust my app / sys vol to the levels I want. The only time this bothered me or I ever even noticed it was when muted facebook vids auto played it would give a soft pop when the card came back on, this is all gone for me now.

With all the high end componentry stuffed into this thing what possible impact on battery life could this have a few minutes at best I would guess... anyhow thanks for the tip!

I just did again. It's definitely an issue with the Realtek driver, because there's absolutely no crackle/ pop while using the Windows default one.

Honestly I'm very frustrated with this thing. I even e-mailed customer support at Realtek (twice!) and have received no response for weeks.

On speaker properties are the center/subwoofer/rear sliders supposed to do anything? On mine they don't. Also when I put the internal sub to 0 I seem to get more balanced middling sound rather than the sound coming from the left. Put on the internal sub to an amount and the sound seems to come more from the left side of the computer. Why does the internal sub drown out so much of the noise on the right side?

Mousepad, the G751 Realtek balanced audio fix is in the new driver v6.0.1.7432 , if you are using that driver you shouldn't have these symptoms, those are the symptoms from before that driver version was released.

Scott, I have the 7432 drivers installed and have been trying to configure the sound settings and came across those interesting findings in speaker properties! There is just something off a lot of the time when it comes to the speakers on this machine. I guess the new driver isn't working properly for me? What are the recommended Realtek program settings as well as playback devices/speakers/properties/levels settings? I'm amazed at how much tinkering this machine needs when it comes to sound! It's really too bad as otherwise it is a great machine.

There are a few other threads documenting this issue, but it's best if we just concentrate everything here. FalkenJeff proposed some fixes which I think might work for most people.

Unfortunately I think that we just have to wait for the next audio driver and hope that it has a fix. It definitely is a driver problem, although I am a bit surprised that more people haven't come across it. If it's really driving you nuts, uninstall the Realtek software and use the Windows generic one.

MY biggest problem is that middle sounds are so very low with these new drivers. Watching movies using the speakers is pretty bad. The middle sounds like voices are so low. If you switch to 5.1 it uses the subwoofer as a speaker and the middles there are decent. So i know it has to be a driver issue. I am glad this driver fixes some of the issues but i really wish we would get another one with actual balanced sound and the crackle fix.

I definitely agree that we need to concentrate this issue to one thread so that we can get as many people that experience it together so that a fix may actually happen. I have also noticed that with headphones I get crackling issues as well so it has to be a driver issue. Brand new headphones. So far Realtek on "stereo" with nothing else ticked and ROG audio wizard on multimedia along with speaker properties internal subwoofer at 50 works best for me.

Hello people, I'm affected by the crack noise issue before and after any audio content.
To reproduce this issue it's very simple: open youtube website and wait for a banner content, which is mute as default but the audio card will make that noise. Then close youtube and after few seconds you will hear another crack noise.
I tried to edit the registry key, uninstalled a previous version of the Realtek High Definition Audio driver, installed the latest available and tried a lot of different versions of Realtek drivers but the problem is still here. In more I tried disabling all enancement effects and chanching subwoofer levels without any success.
Anyone is facing with this issue?

kalo86, what is your Realtek HD Audio Output level set to?

47488

The sound you are hearing is the noise made when the amp gets cut in, when the audio driver opens for output, and when the amp gets turned off, when the audio driver closes.

Kinda like when your Stereo separates when you switch on an Audio Preamp and then turn on the Amplifier - the thump in the speakers you hear when the amp turns on.

The idea is to turn down the Audio level so that crack/thump is reduced, why my level is set to 10, and I use the application sound level to set the sound loudness.

If the system Realtek HD Audio Output level is way up, the crack/thump is much louder.

I get the same crack in the G750, but it is much less objectionable when the level is down low. It's possible in the G751 it's worse than on the G750, but try tuning the level to see if that helps.

Also, drop the Subwoofer level down to 50% to start, then increase until you hear distortion in the subwoofer and then back off a bit. For me about 65% seems a good setting.

Please let us know how it works out for you :)

Hi hmscott, thank you for answering and for your explanation :)
I notice a little backgroud sound after I hear the first crack. Then, when I close any audio application and I hear the second crack (amp off signal) the background sound is off.
These are my audio settings:

03-14-2015, 07:22 PM
Yes, you're right. My settings are at 50 only for testing purpose but if I leave at 0 or 100 the crack sound is always the same.

Edit: I could add further information about the crack noise issue: the problem is also present when the audio is set to mute! Absurd! Every time I am going to open an audio content like banner (also the new banner in uTorret for example), YouTube videos, mp3/FLAC audio files being played with VLC or other player, I hear the crack noise. I suppose it's a driver issue.

Mousepad, some application volume controls are linked to the Windows volume, but many/most aren't. All of my media playing tools let me set the output of the app at 100% and I can then run the Windows volume level - amp level - low.

Here is Media Player Classic HD set to 100%, while Windows Sound level is set to 6%, so I don't hear the crack/thump - youtube is the same, Leawo Blue Ray Player, etc.

youtube 100% windows system sound 6%

I have the same issue Kalo. Turn all volume to 0 including the applications and the crack still happens. The volume level in application or main output doesn't matter.

Thank you Mousepad for posting your experience. I was a little bit afraid of a fault machine but I think that the G751 has an audio driver issue.
I hope Asus and Realtek solve this "little" problem, then we'll have a rock machine :)

I have the same issue Kalo. Turn all volume to 0 including the applications and the crack still happens. The volume level in application or main output doesn't matter.
Scott, I think our issue is different than what you are talking about or for whatever reason you are able to minimize it and we are not.

Mousepad, sounds like it is worse/different that I have, and I can correct it enough to not be annoying...

Ran across this little note when searching for crackling audio on Notebookreview.com:

M18x R1 speakers Popping/Crackling sound
http://forum.notebookreview.com/threads/m18x-r1-speakers-popping-crackling-sound.722925/#post-9270900

"I used to have this problem, when playing YouTube videos every now and then.you'd hear a static crackle and some distortion regardless of if you were using speakers/headphones

This sounds very weird but I had Norton internet security 2013 installed, after I removed it the audio distortions had gone. And I tested this out a few times, before installing no audio problems then after installing I start getting the static crackles.

I know it seems very far fetched, but if you have Norton internet security installed and you are running out of ideas maybe see if removing it fixes the problem? "

Here is another thread where that NIS is mentioned as causing lag / audio distortion.

I am also running Norton Security With Backup - a newer version than he mentions - NIS - so it might be related, are you running NIS/Norton?

I am running the same one you are and I uninstalled it but it didnít work. That first thread you linked had another link to an "IDT" fix in the software where a bunch of Alienware users had/have the same problem and fixed it through disabling power management. Unfortunately our control panel doesn't have that option and the regedit doesn't work. Iíve also tried deleting the whole power management folder in regedit and that doesnít work either lol.

Mousepad, it's all worth a try :)

Let's hope something comes through from Realtek to fix it.

Did you, and others, report this crackle to Asus support? As a Technical Inquiry filed here:

https://vip.asus.com

Did you try both 0 and 1 as the regedit value? Some say one works, others say the other works... weird. For me it was fixed by setting to 1 - Enabling the Disable :)

I have tried 0 and 1 and neither seems to do anything. I filed a technical inquiry a few weeks ago and got back a general RMA response. It would be nice to know directly from Asus if this is a driver issue they are willing to fix or if it is just a defect or something they don't want to fix. I have held on to it being a driver issue given the ridiculous amounts of people that have had this issue and not just on Asus laptops. I will RMA if I have to but I am holding out in case they can fix this with drivers.

Mousepad, you can resubmit the request, using the same case number, and ask to escalate to a supervisor, and then ask to escalate to an engineer - let them know about your posts and others posts here. PM cl-albert for help getting it escalated - pm MarshallR@Asus to let him know it is a remaining problem with the G751.

It may not be fixable, if it is the same sound I am hearing - maybe to a lessor degree - it is the amp engaging and disengaging - and may not be mask-able, but if it is bothering you then pursue it until Asus says one way or the other whether it can be fixed.

I don't know that a physical RMA is needed, but I guess Asus might want to take a look at one that has the problem worse than what they are seeing.

I resubmitted the request and asked for a supervisor or engineer. I alo pm'ed Marshall and Albert. I'm hoping we can get somewhere with this. Thanks for the help Scott.

It should be fixable in so far as I can tell. It definitely is a driver issue, so it's just software. The problem disappears if you run in Safe Mode or uninstall the driver completely and revert to the Windows default one. Having spent hours and hours researching this, it seems the only commonality among users experiencing it is the Realtek HD Audio driver. It makes no apparent difference what hardware they have. My best guess is that there's a conflict somewhere preventing the RegEdit workaround from functioning. Maybe the edits worked for users running Windows 7 as opposed to us on Windows 8/ 8.1?

I have had the same experience that uninstalling them makes it go away. I haven't tried Safe Mode. Just as an FYI I tried newer drivers 7443 and they actually made the crackling worse. I left them on for about a day and it seemed to crackle even while audio was already playing. I've since switched back to 7432. So clearly a different driver can make it worse so I think this may point towards driver issue even more. If anyone wants to try the newest one and report back on if it is better/worse/same here it is (note these are unapproved drivers) - http://support.asus.com/Download.aspx?SLanguage=en&m=Audio&p=3&s=111
