I spent some time and I prepared SoundPatch similar to 7floor modification.
The difference is: It's no need any hardware modification, only patched MCU firmware and modified android Amplifier apk
That's how it looks:
Remember
I am not responsible for anything that may happen to your unit by flashing the mod image.
You do it at your own risk and take the responsibility upon yourself.
Update 18-08-2019 (remarks below)
@adrianpop1990 has prepared repository on GitHub. Many thanks for him

Revert to previous version:
Inconveniences what I noticed:
In Music app, the button marked in red (below) works not properly when Amplifier app not running in the background

Have a nice fun/use/whatever
Update:
Please don't ask for patched MCU firmware for other versions & other manufactures. Maybe, if I will find more free time, I will prepare more versions.

* Notice *
Some users reported issue with installing ROOT version (I did not have that problem and still have not).
Possible solutions at posts: #486, #542, #552
Revert to previous version:
- Flash your original MCU firmware
- Amplifier apk:
- If you installed only MOD version, uninstall it
- If you applied ROOT version you must install original version MTCAmpSetup.apk
