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

    EDIT - These drivers seem to allow us to disable Realtek power management ftp://ftp3.realtek.com.tw/Realtek/Ge..._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 having the same issue and haven't found a solution yet. The strange sound doesn't only come from the headphones when they are plugged in. The subwoofer seems to play a moderately loud noise even when 3,5 headphones are plugged in. I also noticed that the subwoofer is producing white noise when the sound card is active (playing music through headphones). It's very quiet, but it shouldn't be active at all.

    cl-albert, thank you for focusing the threads to here

    Also, you can try a newer Realtek driver, Version V6.0.1.7443 for Windows 8.1 x64

    I have tried the newer one and I thought it made the issue worse. Has anyone else given it a shot?

    I am running the windows install that came with the computer and I just took off the bloatware. Albert you mentioned that you have a fresh install. I wonder if anyone has tried reformatting with a fresh install to see if that randomly fixes it?

    I have done a fresh install with a Windows 8.1 DVD and then installed all the drivers from the Asus website including the latest Audio and for me it felt like a difference for the sound when I go past 60% with the new AUDIO driver it does not sound terrible like it used too.

    Sorry if I got the information wrong but wasn't the sounds that pop up now and then from the fan starting or something about the HDD?
    I just get a sound when moving my mouse or opening the browser after taking a pause from browsing and such. And another different sound would be the one you get when you put a DVD in the bay but like very short when you don't actually do that, just starts random.

    I think the QuietHDD issue is a different one than this as I have an SSD and others have posted that it is different than that.

    As for the DVD noise I'd rather not go too off topic but is it this at about 3 seconds in? - https://www.youtube.com/watch?v=VEcpKcsm7U0 When I took out the DVD drive it stopped but now I am not sure what to do as I don't want a hole there so I put it back in and it sometimes makes that noise for no apparent reason. It doesn't seem to affect anything though. Mostly happens when I boot the computer. Do you have the stock DVD drive that came with the machine?

    Oh okay sorry then, I have the model with SSD and HDD.

    Yeah I thought being still a noise it can relate a bit my bad. Yes something like that, oh well it's good it does not make it too often. I think when booting it up the sound is normal, it's weird that it makes it after sometimes too. Yes the one with Blue-ray as my model was the G751JT with SSD, 16GB of ram and Blue-Ray.

    Actually, just wanted to clarify that I still did a recovery with the ASUS image, but it was not with the original factory image and was a (slightly?) updated ASUS factory image if it matters.

    If anybody can just check this issue after doing a reset/recovery with their factory image before installing anything else (anti-virus, etc.), it should probably be good enough to eliminate any software issues.
    You might also want to install the latest drivers from the ASUS download site, but I didn't notice many that seemed like they would be related to this.

    Since I'm running the 206 bios, we may want to compare bios versions as well and I can try to downgrade my bios version too if necessary. Thanks.

    Mousepad, the new 7443 made the sound louder?, longer?, worse in what way?

    Also, keep the Asus Windows build, that is what Asus uses to recreate problems - it's their OS, so why would they do a from scratch Microsoft Media install?

    It is tough for Asus to recreate a problem reported from a non-Asus Windows install. Keeping everyone at the same image is important when debugging.

    EDIT - I re-installed 7443 to try the Regedit fix thinking that, hey new driver maybe I can disable power management now. It didn't work. It did give me another chance with the drivers and the crackle is the same. It did crackle while I was in regedit though which was weird. I still think this comes down to the Realtek power management and for whatever reason we can't shut it off. There used to be a box you could uncheck in the software to disable it but it is not there anymore.

    I really have zero idea of what you are talking about with the whole Asus Windows build? I was mentioning this because Albert said he had a new windows install so I was curious if others had the Windows that came pre-installed or a new install. I asked this to find a link between us as we seem to share a problem and yet no common link besides owning G751's but others also share that link and the crackling is minimal for them....Why is the crackling only loud for some of us? Why do other notebook manufacturers have this crackling issue but for most people the Regedit PowerMGMT fix works but for us it doesn't?

    I will try to contact the repair center where I am at on Monday but unfortunately I am not in the U.S. right now so I will have to see how it goes. Will report back on what they say. Hoping they speak English!
