Hello,

My new Asus makes a weird noise on boot but not always and it also makes the same noise at other random moments. It has made the same noise when plugging in a USB or SD card. It has also done it at random moments during computer usage. Is this a normal noise? The video is from boot. https://www.youtube.com/watch?v=VEcpKcsm7U0

I also made a video of a second noise that seems to be coming from the upper left corner. This one happens quite often but it is more subtle and seems to go on and off all the time. It's like a tiny click then whoosh(or hiss) and then click again. It's different than the fan noise and is harder to hear on video so you likely have to have the volume very high to hear it. In the video I kept opening and closing a windows media video(hence the mouse clicks) and each time I opened it the noise would start and when I would close it the noise would stop. https://www.youtube.com/watch?v=RBUPzCKacXA

Do I need to RMA? I reached out to technical inquiry but they couldn't view youtube videos apparently.

Thanks.

Have you trying to figure it out? it could be, Optical drive Noise, CPU or GPU fan.
try remove the optical drive and see if the problem solved.

I more just want to know if these noises are normal or not and if they are not I will RMA. My guess is they are not but I want to make sure before going ahead with the RMA process. Do you ever hear these noises?

I seem to have figured out both issues. The first one was the optical drive. I took it out and there is no more screech boot noise. It is completely gone.

The second issue is the Realtek drivers. I had the newest ones and then I uninstalled them and the problem was solved. Asus really needs to get on a fix for the sound issues. I had the same issue as in this thread http://rog.asus.com/forum/showthread.php?57000-G751-Weird-sound-before-anything-plays

Thanks for the help Jlieu

Mousepad, please report your problem / video to Asus, and let them know that it is a problem with the new driver 7432, I am assuming this doesn't happen with the older Realtek driver(s)? This is good feedback to give Asus, they might not have noticed it, while trying to fix the sound imbalance it might have slipped their notice.

https://vip.asus.com <= create login, register your laptop, file a Technical Inquiry - include the URL to the video, and/or zip up a copy and attach it to the TL.

Thanks for noticing the problem, nice catch :)

Done and I uploaded a video where you can kind of hear the noise better but it is still tough to get it on camera https://www.youtube.com/watch?v=j0KjGZNRur4

So the reply I got back from the technical inquiry seems to have been a general RMA response. I don't even get what there is to RMA with this sound issue given when I uninstall the Realtek drivers the problem goes away. Do they have secret working Realtek drivers they can install if I RMA it or do they just give a generalized RMA it answer to technical inquiries? I'm starting to regret purchasing from Asus just because of how bad support seems.

Mousepad, I listened to the last video, and it just sounds like recording noise, I guess you need to be there to hear it live...

It might be a bad audio section, bad part / amp making noise, the driver would be the same - you only RMA for hardware replacement / fixes.

If you can find another G751 to compare, you could see if it is just a normal condition or if your laptop in particular has a unique problem - then RMA it for a hardware fix.

There is also another issue with GTX 970's - I haven't heard the noise so I don't know if it is what you are hearing, they call it Coil Whining - specific to the 970, not sure if it happens with the 970m...

Hmm, I've seen more people complaining about the new Realtek driver but tbh I haven't experienced any issue by now. And I have used the sound card for the internal speakers both on surround and 5.1 cofiguration, I have used it also for my G51 5.1 Surround system and also no strange sounds.
@Mousepad: Have you bought the laptop with the preinstalled windows or did you get it with a freedos and installed the windows yourself ? I'm trying to see if this is a problem solely with laptop that come with preinstalled software.
Mine was bought with a freedos.

I've got the same problem as the second one mentioned by the OP. It's been addressed in another thread, but you can (probably) fix the issue by doing the following:

1. Open RegEdit.
2. Navigate to HKEY_CURRENT_USER\Software\Realtek\Audio\RtkNGUI64 \PowerMgnt.
3. Change the value under 'Enabled' from '1' to '0.'
4. Perform a system restart.

It's basically the driver turning the speakers on/ off when there's an audio input as a power saving mechanism. That being said, this solution for whatever reason has not worked for me. If anyone has any further ideas on how to resolve the issue, they would be much appreciated!

Haha, I finally noticed that little buzzing/fuzzing I dunno how to call it. But it is almost unnoticeable. I will try the fix from ReeveJ and see if it works.

The regedit fix didn't work for me. The easiest way I can reproduce the issue is to open a video with windows media player and when it opens the noise happens and when I close it 2 seconds later the noise disappears. I can re-open it 20x in a row and it will follow that pattern. I have tried 5.1, quadrophonic, stereo and it doesn't matter. The only thing that takes the noise away is uninstalling the Realtek driver but that makes the sound really awful.

I bought the laptop with a pre-installed version of Windows. Also I doubt it is the coil whine issue unless I can turn that on/off by opening/closing a windows media video.

Yep, the regedit fix didn't work for me either. Well, it's quite a very tiny noise that comes from the notebook speakers. It's not that distracting for me because it only plays when I open a media file and/or when I skip scenes of a movie. It doesn't matter which software I use for playback, the buzzing is still there when I open the files. Well, this is something to be fixed with a future update.

Like I said in my comment, that fix didn't work for me either. It definitely seems worth suggesting, though. I seriously hope that somebody finds a working solution!

It definitely is a driver issue and the problem seems to be related to the power management mechanism in some way. I just can't figure out why the registry entry doesn't appear to be controlling the driver. There might be a conflict somewhere, but unfortunately I don't know enough about Windows 8/ 8.1 to say for sure.
