View Full Version : Speaker Problems - Help :(

11-12-2011, 04:34 AM
So I'm having some problems with my speakers. When I close my laptop it makes a LOUD whistle sound intill the computer shutsdown. At first I wasn't sure what it was but after playing around and noticing it was coming from my speakers I muted the sound before closing the laptop and it did not do make the sound....

So now I'm sitting here tryin to figure out what the hell is going on...

any suggestions or links to the same problem?

Anyway to turn off the built-in Mic on a G74sx, I tryed disabling recording in control panel but the dam thing seems to still pick up sound. I think that these maybe the problem.

I don't know if the microphone is the problem, but you can disable it in its Properties window:

Did you attempt to enable microphone Noise Suppression in the Realtek HD Audio Manager?

While you are in Realtek HD Audio Manager, is Microphone Boost enabled? If so, try turning it off.

When you make a recording in Sound Recorder, is the sound clear?

Try going into the mixer and turn down the mic volume.

Still having issues. The mic seems to be on all the time, even when simply moving my laptop around the built-in mic picks up the sound of the laptop moving around. As stated before the worse part is when you close the laptop the load whistling sound coming from the speakers.

Disabling the Mic works, but I use my headset often when gaming so turning it on and off doesn't seem like a solution..

Having my headset plugged in disables the built-in mic and stops it from playing back all sound it picks up but thats not a solution....

Do you want your notebook to stay awake when the lid is closed or to sleep?

Doesn't matter, I believe it goes to sleep. It will take about 20sec before the whistling stops then you'll hear the fans turn off.

Anyone know if they have a service repair provider in the Milwaukee Area? This is one of many problems I've been having with this thing and it's only 30 days old (tigerdirect only accept 14day returns on laptops already tried)

Open your Realtek HD Audi MAnager. I have Microphone set to about 50%, Microphone Boost is on, Noise Suppression is on. Default Format is 16bits, 44100Hz

In Speakers, my volume is set to about 67% , Stereo, No effects, 24bits, 48000Hz

Device Advanced settings Tie up same type of input jacks, selected, the other not.

It seems like your mic is playing back everything it hears through the speaker. So when you close the lid, it starts looping the sound of the closing lid until its a high pitch squeal (aka feedback).

I'm not sure if you actually want playback through speakers, but judging from your previous post, it seems like its playing everything the mic hears.

Go to your microphone properties, click on the listen tab and uncheck "listen to this device". This should fix any problems with any noise picked up by the mic.

I bet that's it. Good one, Holyman!

I'll try that when I get out of the office and report back.

Thanks for all of the help!

We live to help utter strangers abandoned by the corporate giant. lol

Ok, problem solved. It was not "listen to this device"


But after playing around with Realtek manager I turned off the "mircophone boost" and that seem to work.


Now I just need to figure out what the deal is with my fan.

I'm so glad. Phew . . .

Now I wonder if that fixes the underwater sound, too. Doubt it . . .

I had the same problem here and it hapened after i enabled the playback from the RealTek HD audio manager. I went back and disabled the playback and kept the mic boosting at max and I don't hear any noise from the speakers anymore.

Thank you for that feedback. I'll try to remember that tip.
