G751 Sound Crackling Thread (The one thread to rule them all)

Level 10
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'm still not convinced that its a hardware problem. Why would removing the driver and using the default Windows one fix the issue?

I'd like to try this new driver, but is it official? How come the only one I can find elsewhere is the February, 2015 release?


Yes! It is directly from Realtek!

I've installed the 7624 drivers and they seem to solve the problem after setting Power Management to '0.' You guys might have a finer ear than me, but I can't distinguish a 'shh' noise from the sound of my fans - and I'm in a very quiet room. It's case closed as far as I'm concerned.

Hi,

I just recieved my G751JT-T7172H (one of the rare G-Sync model) today.
This model is now out of stock here, so with a bit of "luck" I found one which was repacked.

I checked everything, not a single scratch or anything wrong... until I heard these nasty & unfamous sound crackles. 😞
But I confirm the new 7624 drivers and the PWM trick solved the issue here as well.

Thank you so much guys, I would've been mad to return this baby 😉

Realtek response...with newer driver!!!
I previously emailed Realtek about this issue and here is there response I received:


"Hello,


Could you please confirm below v7629 to see the issue still there?

if not works, please have a dump.txt to us for checking by running attached file. thanks.


ftp://spcust:hwwk758z@ftp3.realtek.c..._Win7_WHQL.zip


Best regards,

PC-Tech"


My findings when using this driver are as follows:

The noise at the beginning of the testing is still present and remains the same...However, the noise is slightly less noticeable at the end...so the noise is a softer crackling/popping and the noise at the end of the test sound is more delayed...thus it takes longer to occur when it ends than previously.


I have emailed Realtek of my findings and have submit the Dump file for further processing and I will post their response here when it is received.


Mind you, the linked driver does in fact help some...but when or after adjusting the power management as previously mentioned...it does appear to help even more...Especially, if you use a windows startup sound...this uses up the first noise then keeps the sound active...at least with my experience.


Here is the posting about adjusting the power management:

"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.

Use the Windows button + R together to open the Run menu and type in "Regedit" and hit Enter
Next navigate to the registry key as listed above: [HKEY_CURRENT_USER\Software\Realtek\Audio\RtkNGUI64 \PowerMgnt]
Then look for and right click while on "Enabled" in this registry key to "Modify" the power management
While in the modifying of this key look for and in the "Value data" area type "0" and click "OK"
Restart your computer...this is important!

Now you will experience the results of all the work...just as others have!


NOTE: Open the following using "Paste and Go" in Google Chrome...because there is no password needed and it just begins the download auomatically:

ftp://spcust:hwwk758z@ftp3.realtek.c..._Win7_WHQL.zip


Hope this all helps...and you are welcome for the new driver!

Cheers!

The Doctor!

Please contact me if you have any further questions or additional information.


Again, I wish to remind everyone there is no total FIX...this is just a bandaid to the problem overall!

Sorry for delay.

Thanks but still no joy with this new link ...

What sorcery is this ? :rolleyes:

With realtek's weird ftp and this forum which ask for captchas at each post, internet is a real matter of fun, joy and laugh. 🙂
