Very low speaker volume on Zenfone 6( Asus 6z) - ZS630KL

I'm using an Asus ZenFone 6 or Asus 6z, how it is known here in India since May 2020 and it has been working fine except since the last two updates (security patches), the speaker volume has reduced drastically.
Model Name: Asus 6z - ZS630KL
Firmware Version: 17.1810.2011.183
Rooted or not: Not Rooted
Frequency of Occurrence: Everyday
APP Name & APP Version (If your issue relates to the app):
In addition to information above, please also provide as much details as you can, e.g., using scenario, what troubleshooting you've already done, screenshot, etc.
========================================
So, I play some music and the music plays fine for like a couple of seconds and after that, the volume reduces significantly. Additionally, the upper speaker or tweeter gets louder, or maybe the lower main speaker volumes makes me think that.
So far, I have tried disabling AudioWizard, clearing its data, rebooting my phone. Since I was facing this since the last two updates, I just waited for one more which was sent out in December some time. It did not fix it, it is now that I am seeking help here, in case anyone has been facing the same issue and has found a possible fix.
I took this long because I don't really use the speakers to listen to music, but because I know it, it annoys me. Moreover, it happens with ringtones and alarms as well, loud foe a couple of seconds and then much quieter. Thanks in advance.

Regards,
Scooo

a friend of mine helped to immediately dry everything out
Describe exactly how he dried it, that's very important. The water wasn't distilled, I suppose. What kind of water was it?
Anyway, it's now clear that it's a hardware problem that was caused by the water.

So, this was in September, the water was regular tap water as it comes in india, not distilled. He had a heating network at his home which he used to get the back panel off.
Then he disconnected the battery and then took other components out, he dried everything well with the same heat gun. Every component in there was dried up completely, however, he dared not to remove the speaker from the plastic housing thing, he instead heated to evaporate water out as much as he could without melting the housing. After putting it back together, everything was working fine, the phone was as good as new.
The speaker continued to work well until December, that is, it worked for nearly 4 months pretty well. No issues at all, it was around the first week of Dec that I was noticing the sound being biased towards the upper earpiece.

Again, I am in 20% doubt because the speaker plays properly for a second or two and then the sounds reduces in bottom - that too progressively, and goes over to the upper ear piece.

Thanks for you time, I really appreciate it, hope we get somewhere.

He used a very brutal method, which in itself could cause damage. Water or moisture needs to be removed as gently as possible, see those references I've been adding. And the desiccation should take place as long as possible, ideally several days.
It is important that there is not a single hidden drop of water, or any moisture, left before the phone is subsequently turned on and used.
Otherwise, even over a long period of time, faults can gradually appear.

Thanks man, I am checking those references you've been adding. I'll try them all and if no change, then try to get a spare.

I'm now convinced that the speaker is indeed faulty, do you think that's the reason why the upper earpiece is louder? Because I assume there is one common amp for both pieces, and because the bottom speaker gives up power after a few seconds, it allows the upper earpiece to consume and produce more?

Thanks,
Scooo.

It is now too late for any attempts to remove moisture, this is completely unnecessary.

I can't begin to guess what exactly is damaged. What you're seeing is some kind of side effect of one or more primary water damage.
