Asus G1 Laptop Making HIGH loud pitch constant noise

post #1 of 9
Thread Starter 
I just got my new laptop (Asus G1)
I started it up and everything works fine, including the speakers. I then played a game and used a headset with mic. I then left my computer on and came back after awhile when it was in screensaver mode. I clicked the mouse to exit the screen saver, then i took out the headset and mouse + battery, it then began to make a constant Screaming Loud Pitch noise.

It does this when my volume is set above 48/100%. I can play music fine as long as it is below 48, but if i start to turn it up it makes that loud annoying sound.

What do you think the problem/solution is? thanks

I have an Asus M50vm and it does the same thing - like, wake up the neighbors, loud screaming sound that is unstoppable. Always happens when my volume is above 50% too. Have you figured out what it was? I managed to turn the sound off after a few minutes by disabling audio but it scared the hell out of me and sent everyone in the house running to see what was wrong.

What type of screaming? Is it coming from the speakers or the laptop its self?

Disable your microphone input and it should go away, fairly common issue.

It's from the speakers, and yeah - after about an hour, I realized that the noise probably stems from feedback from my microphone, but it highly depresses me that I am unable to use the microphone (i.e., my microphone can't "hear" normal speaking volumes, which forces me to use "boost," which ends up in the screaming feedback). Why buy a laptop with built-in multimedia capabilities when you have to disable those capabilities?? Grr...

Install the needed audio drivers and enable "Acoustic noise canceling" and "Acoustic echo cancellation"

FreeRoller has some good advice. It may work.

I must add the disappointment in this is misplaced. It is a law of nature not a design defect. If FreeRollers tip works and you ask yourself. "why did they not just have as default"? Well if you used external mic the placement would be different so might not be needed. Also any audiophile is cautious when using "noise canceling devices" as they do alter the true sound. To an acceptable level is all about opinion.

As said this is not an Asus issue or manufacturing issue. It is a physical phenomenon of creating a sound loop. On a positive note if the sound was enough to drive others from the house you are lucky as sounds like your notebook speakers are pretty good.

Not to be a smart ass or rude. And I too have had this issue and even took me aback. And from growing up playing guitar and doing music still caught me off guard.

Since you now know why and not a problem I hope you are relieved. Let me give an example to express the futility of your wants prior to understanding the cause.

If you went and bought a motorcycle. You came back to the dealer later that day and said when you went above 50MPH your eyes started to water? Well you would not do that because you understand it is what it is. Well it is the same with your situation and now you know why. You would get sunglasses?

Other than the software solution suggested hardware options that should work also. Buy a cheap external mic. If it can be uni-directional that would be even better. If you use external speakers that should help also with internal mic because you have separated the sound source and sound receiver. Of course both being external would give you the best. And even doing so at a high enough volume or boost a sound loop will be created. And thank God for that or we would not have had Hendrix and many of the hard rock/heavy metal/grunge.

Good luck and fun computing!

Well, I think it worked. Thanks to xFreeRollerx for the idea of utilizing "Acoustic echo cancellation." I did the following:

(1) Deleted the drivers
(2) Reinstalled the RealTek drivers from the Asus m50 driver CD
(3) Put microphone levels to +100 and boost to +20.
(4) Enabled "Noise Suppression" and "Acoustic Echo Cancellation"

While speaking in Sound Recorder, my voice is still barely registering visually, but at least it appears to work on the playback end, if the corresponding volumes are turned to the max. Mushy, but workable.

And as for Asus Mobile, I guess my disappointment stems (known audio feedback loop problems notwithstanding) from the need to purchase external devices to make up for an advertised built-in utility.

I have mic equipment (an USB-modded Shure supercardioid dynamic mic, as well as these stick-like desktop mics from Logitech), and while I'm not an audiophile, by any means, I had hoped that this would eliminate the need to haul more accessories around, as the laptop is usually out of the house 5-8 hours a day (on average), and I'm already toting around a lot of accessories and 6-pound textbooks. I probably should have bought an ASUS EEE :-)

I guess the relevant analogy to me, is if the hypothetical motorcycle manufacturer built in a speed delimiter of 50 mph into the engine, then advertised the function as the "anti-sunglasses! feature." However, the manufacturer knew full well that the function would not work as advertised (i.e., that you'd need sunglasses, regardless of the delimiter), and that the majority of people (the classic uneducated laptop consumer - that's me!) would not know that enabling the delimiter would not allow the function to work well (in this case, because of the physics of sound interference).

<sigh>

Oh well. Limping along is better than not moving at all! Thanks everyone for your help... and I'll enjoy this new laptop - except for this dang keyboard lag! The Asus M50mv has a lot of bizarre issues... some generalized, some unique ;-)

No disrespect but are you for real? What issue of this situation are you still confused about? Not a joke? What issue are you still dealing with?

You had no problems why you must make one is beyond me? But I do want to hear the outcome.
