Are you blind? BTW, the tuning of the audio has little to do with absolute volume. One is quality and the other is quantity.
Consider me blind, and I am okay with your trolling!! but did you read my request? did you get what my problem is? have you tested the codes your self?

to make it easier to your hard brain, it should be one of those codes for some smartphones (*#*#3646633#*#* or *#*#54298#*#*) but any other phone that doesn't work with these codes should have its own specific code. the list I am looking for opens access to a few system settings that can be modified.

This link will show you what is engineering mode is, have a look at it as my tiny little eyes are blind.

Can you try of either of the second codes would work on your device? They do not work on mine.

Did it occur to you that your speakers were not designed to do what you wish? I would suggest rooting your phone and using app, like Viper, to increase your volume.
Not really, you got the point wrong, or maybe I did not clear my self enough.

the point is that when I do a video call over internet using google duo or WhatsApp, the other side complain about low volume and can barely hear me, while if it is speaker mode on a voice call, it is completely fine. video recording got no problems at all. I tested apps like microphone amplifier and it worked perfect with increasing audio gain from the mic, quality and clarity, even the ambient sounds where just perfect.

I couldn't reflect that outcome to the phone as its functionality is limited, and the only way to do it is to modify system values using engineering app (you can check a few youtube videos by changing SIP of audio settings, as audio settings controls speakers, earbuds, normal use, and microphone in all 3 modes). Another option was to disable noise reduction which is not available in the mi 11 ultra.

I have never had issues with the microphone. When you hold the phone for your video chats do you accidentally cover the mics? While I don't use WhatsApp, I have tried it on Zoom, Duo and Facebook Messenger without problems.

Nop, even I checked all 3 mics down and top and behind the camera bump. All working and not covered or blocked. I even removed cover and tried without it holding the phone with just 2 fingers, same issue.

May I ask which rom you using??

I have also tried factory reset few times, even after latest update 12.5.4
