View Full Version : G752 Speakers turn on and off

I'm back in the game, returned my unit, bought another one..

Can't lose the love for the G752.. NVMe's a poohole.

Anyhow, speakers seem to turn on and off, they make 'chick' sound to turn on, play the sound, then they go 'chick' again and turn off.

How to keep the speaker always on, or reduce the hiss? Very odd for a speaker to have such an active sleep mode.

That is the 6 million dollar question. When you find the answer...please share.

Yeah I notice this as well. I assume this is some power saving mode for the audio amp. Below some minimum signal level the amp shuts off entirely. It would be nice to disable this "feature" but I doubt there is a user control for it. Injecting some low level continuous signal into the mixer, at a high frequency like 20kHz (where nobody can hear it) might do the job if somebody wants to write an app to do that. Of course that would have to be done without locking out the audio device from other applications and it would waste precious cpu cycles. Probably not worth it.

IMO, poor analog and software engineering on the part of ASUS. They never should have released the feature with an audible click (power down transient) like that.

Hi,

Could you please tell me which G752 model you purchased and provide the video for us to confirm?

Thank you.

i think this is the same issue like on g751 series...popping sound also on muting!
find the tread u know what i mean!
its confirmed by many users :-)

the app is already there in the tread of g751! its a wav-loop as service.

shame,shame,shame

OnePiece@ASUS,

This problem is well known around here. You can test this yourself on a G752. Just play a system sound and then wait for the click that follows about a second or two later when the amplifier shuts down.

It would be nice if there was a driver option that would keep the amplifier powered up continuously to avoid the transient clicks. Yes, this would use a bit more battery power, but who is running these things off battery power anyhow. At least provide the option if the hardware supports it.

If you really can't make this happen I can provide an audio sample of the problem.

I took the time to record two samples of the audio system clicking using a high-quality portable PCM recorder (not a phone).

One recording is directly from the headphone output and the other from the speakers. However, this silly forum will not let me upload WAV files and it won't let me upload both files in a ZIP archive because that is a whole 3.1Mb and that's too large apparently. :-O

So, ASUS, if you would like a recording of what this sounds like let me know how to upload the samples. They are two 2.6Mb files. That represent about 15 seconds of audio per recording. The sounds are simply two different Windows system sounds that we all hear routinely.

I cannot compress these down and retain the audio quality so what would you like me to do?


FORGET ALL THIS -- I added Dropbox links below so hopefully the ASUS people can hear the problem.

Okay... I guess I'll just use the cloud and end my frustration with the forum limits.

Here is the sound recorded directly from the headphone jack. You can clearly hear the initial click in the audio as each sound starts playing and then about 2.5 seconds after the sound drops out, you can hear the amplifier shut off. This shutoff sound is more subtle and more audible in the right channel. There is a period following the first sample where the hiss ramps up just after the amp shuts down and just prior to the 2nd sample playing. Ignore this... the recorder was mistakenly in auto-gain mode.

Here is the link to the sound the speakers create. This was recorded with the onboard mics of the recorder. You can clearly hear the initial click in the audio as each sound starts playing and then about 2.5 seconds after the sound drops out, you can hear the amplifier shut off. If you turn the volume up, you can hear the hiss of the amplifier get cut off when it shuts down.
NOTE, these are EXACTLY the same sounds that are recorded from the headphone jack. However, the initial sound is chopped off as the audio amp takes time starting up and chops off the very start of the sound. Nice!

This should be fixable via a software / driver update. There is no reason the audio system chops off sounds and makes audible transients when going into a power save mode.

There are probably any number of users who would be glad to enable a "Never Sleep" option for the audio to get around these audible problems.

Please fix this ASUS!

I get exactly the same sound from my speakers. Often randomly when no sound has played or is about to play.

I can't say I get it from my headphones though.

Pretty sure there quite a few people that have reported this previously, yet still no fix from Asus.

I only posted these recordings so that the Asus person who posted on the thread could verify the issue. It would be nice if they would chime in again. :-)

Hi. In my G752VT with Bose companion 2 series 2 speakers, jack configured either headphone or front speakers, and with the Bose at full volume, I can barely hear a soft tick just before the sound begins to play and maybe 1 or 2 seconds after the sound stops playing. I think the amp or pre-amp circuit is missing some pull-up or pull down resistors to stop the popping noise. But for my case, at mid volume on the bose, I don't notice it. Probably something to do with the sound characteristics of the bose circuitry/enclosure/spkr characteristics/etc.. Other speakers could exhibit more pronounced popping sounds.

Pretty sure mine was temporarily fixed after updating the realtek audio drivers. And then again after updating Windows to the Creators Edition. But the popping came back.

Hey ASUS!

I provided the evidence in the recordings above. This is an inexcusable problem on laptops that are supposed to have "premium audio systems".

Is there any work being done to fix this or are customers simply being ignored?

High quality sound is very important on machines like this. Word of this problem will effect sales as word spreads.

Please do something about it!!!

It is very clearly a power saving feature, or rather, they probably did not plan the on/off switching of the audio circuitry to be audible. There won't be a fix as leaving it on draws power (ASUS won't do that), "fixing" it would require hardware changes (not happening). You can go with the override solution (playing a blank wav on repeat) which forces audio to stay on, but it will draw more power.

If it's gating power based on the input signal the blank wave file wouldn't work.

It's whether something's intending to play sound or not, I believe a blank file should work.

Even if there's no sound on the wav.. there's still 'sound' if that makes sense.

What's worse is it now affects EXTERNAL speakers, and gawd is it annoying. It's a driver issue.. it happened with the G750's when installing a driver too recent, you needed to use an older one.

We just need a new driver at least one that gives us the option to turn off the sleep mode.

"And I also click the speakers. Also interesting is a solution"

I also have clicking speakers, I'm also interested in a solution.

I have clicky speakers too. Really annoying.
