GL504GM built-in speaker volume fluctuating loud/soft

[Bandem]

Today I wanted to fix a problem with sound. I think the problem is with very loud speakers. They are simply not configured. My guide for this problem.
1)Reinstall sound driver.
2)Install Sonic studio 3.
3) base mode> off effects sonic studio> equalizer> custom> configure every line -6db.
4) Restart your laptop.
It's work for me today. I don't know if this will work tomorrow or next week. I never, never, never will buy asus laptops.=)

You can also set -3db in equalizer or sound volume 50-60%.

I did the same thing with openning my laptop and just strengthen the connection. Meanwhile bios 310 come along. I am not sure which helped, but now its working without sound fluctations.

It works !!! Did the same - opened my laptop and checked all connections to the motherboard.
I also had a problem with cooling fans reving to high but they are ok now.

if anyone is having this issue and can't find fix for it, i have what solved mine. There is a faulty hardware in right speaker that causes it to turn volume up and down. I did as i've seen in other post from this forum and opened my device and then went ahead to move that speaker cable and making sure it is well plugged in. And boom, problem solved.
Despicable that a product of this value has this kind of issues and must be the users who must take care to find the solution, but at least we can help each other in here

The problem came back after some time, but once again I opened the laptop and tighten the connectors (fan and speakers) and its gone. Definitely hardware issue.
Asus support still talks about new bios and resetting windows... RMA repair changed nothing.

I did the same as others posted. A few months back I opened my 504 up and noticed one speaker does have a poor connection. I have basically reinforced it in a way that hopefully the wire doesn't pull the connector back out.

its been fine every since.

GL703GS here and it started fading volume up/down depending on the loudness of the song (louder moments = volume fades too much)... So I hope is the same issue reported in this thread.
Did the wire unplugging and plugging back in definitely fixed it for you, or the problem came up again? Still wondering if is software or hardware...

In my case it completly solved the problem. I had to reinforce the cable since it seems the whole wire is faulty (stick it with tape from the speaker to connector to avoid any kind of movement). The only problem i faced later was the left speaker started crackling, wich was caused by the exact same hardware issue, wich i solved by the moment using the same method (avoiding attach it too much to the battery to avoid ground noise issues)

But in my case is not exactly "random", it happens when the music has deep bass etc... for example Irreplaceable (Beyoncé) causes this fluctuations, but other songs sound good...
I'm still unsure if that's a software safe limiting setting or a real HW problem

EDIT:
I finally decided to open my ASUS GL703GS and have a look to the speakers connectors. So I unplugged them in part and plugged them back again. Nothing changed. As I suspected it is a software issue (Windows 10 VS ASUS/Realtek) in my case.
The strange thing is that for a pair of weeks in october it sounded so good an loud that the chassis was vibrating, maybe a Windows update who knows... sigh...
