Hello everyone!

I've some problem with my Asus subwoofer, when I'm listening some music with the speakers and the volume is more than 70 (actually is when I'm listening it out loud) the subwoofer just turns itself off and then on again.

I've recorded an audio to demonstrate it:

CARE, THE AUDIO IS REALLY LOUD
https://www.dropbox.com/s/587xoifi7wc2wrz/Audio%20test.m4a

Perceive that in the 15s the subwoofer just turns off and then returns in 22s. I can hear a "clic" like there is some electrical issue and the subwoofer really is turned off and on again.

I've already uninstalled the sound drivers and then installed again, but the problem hasn't gone.

Anyone knows what is it?

I'm using Windows 8.1 64bit
Audio driver: 6.0.1.7283

Thanks!! :)

Marcus

I have the same problem, I just keep the sound turned down. Thats all you can do.

You can adjust the Level of the Subwoofer independently, so you don't need to reduce the Level on the "Front" speakers. :)

Level 50 is kinda low, probably 75 is where I usually run it, I think I turned it down for a particularly bass emphasized track, turning it back up now...

That's a really weird bug... but I think that with this hint I can control it correctly to not turn off again... :)

mvharry@gmail.com, it is to be expected in such a short excursion sub. The "throw" of the cone is short, and from your description it is reaching the maximum excursion point and sticking there for a period, before releasing and working again. I have seen it on large speakers, with lots of power, forcing it to occur using a audio signal generator - bored summer school fun - it took a short throw sub to show the problem in real life :)

You might also eliminate the problem by tuning out the frequency range that causes the resonance by using the Realtek Equalizer in MaxxAudio, then you can have the sub level up higher for the rest of the sub frequencies, I dropped the lowest frequency band control to show you where they are:

To get the expanded view, click on the settings gear on the popup dialog that comes up when you click the Audio Wizard Launch button in the Realtek HD dialog.

40132

Let us know if you can use this to fine tune the audio to the point where you can increase the Sub level again, and post a snipping tool shot of the settings :)

Thanks for posting and answering. I had this problem on my G750JZ, It's now fixed. Just lowered internal subwoofer to 75 from 100. and tuned down the ''31'' range in the equalizer in MAXXAUDIO

Allmighty_bob, that's great :)

I ended up dropping the Subwoofer level back down to 65... 75 bottomed out a bit too much on the Netflix material I am watching.

What level did you set "31" to?

Hello guys! I had similar problem and i want to know - is it normal? It is not corrupted notebooks? Or i can exchange my notebook ot the shop with this problem? And what part of notebook is corrupted in this case?

DoomGart, it's normal with all Audio devices. You need to tune the audio to fit the traducers / speakers to match their capabilities - turning up the volume saturates the sub-woofer before the main speakers - so turning down the level on the sub-woofer lets you explore higher volumes on the main speakers, and the total volume output overall.

There are several ways to overdrive the sub. I turn on "loudness" and "bass" enhancements in the Sound control panel for the Speakers, because at low volume I want extra punch - but turning up the volume past low level will overdrive the sub. When I don't have the enhancements enabled - I still hit the limit on the sub before the mains on some material.

It is a normal thing to have to tune the audio output to match the source material and effects enhancements to match the physical limits of the output devices - you just need to investigate all the inputs and controls and then use them match your source material to the output devices.

There is no reason to return the laptop if you can "fix it" with tuning :)

But if sub-woofer will be overdrive in default system setting, i think it is not normal and Asus need added restricted for work mode and setting for sab-woofer.
What do you think about it?

And i have another problems with g750, if you'll excuse me for my off top.

At first, i have similar problem like this: rog.asus.com/forum/showthread.php?50612-Headset-problem-on-g750jz&country=&status=
but i turn on all mic setting and it doesn't help. I had problem with Razer Craken Pro. Maby it problem caused by audio audio splitter in Kraken, i don't know. But my Kraken works properly in other notebooks and desctops PC, i tested it at home and at my office. But another mic from low cost garniture work normal with my book. What is wrong, do You know?

And my second problem is laggs with HDD. If i run films from my HDD i have random laggs every 10-40 minutes per 1-3 sec. If i install some games on HDD, when i playing in it, i have laggs too. If i use SSD, i haven't laggs. What could be the problem?

DoomGart, normal is subjective. If you mean "if it is at all possible to overdrive the subwoofer then it is bad"... no, I think I appreciate the freedom to explore the limits of the subwoofer with the controls provided.

The subwoofer sensitivities can be tuned for the material being played, such that it doesn't bottom out, so it is ok.

The subwoofer is a narrow band transducer that is sensitive to the material - and it's limits can be reached - but due to the physical limitations of the space available - it is the best that can be done .

Unless you invested $ into a front end to the subwoofer that would auto-tune the signal to not hit the excursion limits of the sub with any material in any circumstance - and that would raise the price of the laptop. If Asus could develop an inexpensive solution, I think it would just get in the way... and people would complain about it.

I think it is ok, either that or leave out the sub-woofer - and if you cut the level on the subwoofer to 0, you will see that the subwoofer would be missed if left out of the laptop.

As to the other questions, please start a new thread, or better yet, find an existing thread on each topic and read there for answers, and post if your specific question isn't covered in the forum yet.

Thank you for the excellent questions :)

Ok, thanks for the answer, but i disagree with your oppinion about subwoofer functionality. I think, if company anonced and sold such device like notebook with sub, and if we can overdrive sub with default sustem setting, company should printed messages about it. But Asus printed only positive feauteres about subwoofer. It's lie for customers, i think.

DoomGart, if you feel that strongly then please tell Asus directly that you feel lied to:

Register your login here, register your laptop, and file a Technical Inquiry:

https://vip.asus.com

And then tell Asus what you are telling us. If you feel it needs to be said to Asus, it needs to be said to Asus directly. Some Asus employee's read the material here, but this is a user support forum.
As you know, i had 3 problem woth book and in this case i send a letter to Asus directly on previous week. They tell me that i should bring my book to service. But service didn't repair/fix my problem. Yestarday i write second letter to Asus and i decide find any information here:)

DoomGart, you can understand that Asus isn't in business to teach you how to configure and use your computer. They have to assume some level of expertise for their customers.

Simple Windows / MaxxAudio tuning fixed the subwoofer problem you were having, The HDD lag is also curable with quiethdd <== search the forum.

The Kraken headset issue is well known, and there is no solution on USB 3.0 only laptops. The G750 only has USB 3.0 ports...

I think you are expecting a level of hand holding and perfection in function that is unreasonable.

You have to accept the responsibility that you don't know enough to configure your G750 yet, it is new, it takes time to learn what you need to know to get out of it what you need.

Asus is no different than any other laptop maker, you will find problems with anything you purchase, and there isn't anything to be done except for you to learn and gain expertise on how to deal with the limitations.

That is what we do in the Asus user forums. Here we xchange information on how to best configure, tune, and fix the G750.

Be sure and spend some time reading the past posts. As you can imagine these questions have been answered many times already, and you only have to search and read to gain the expertise you need to get the most out of your G750. :)
