Editing the files mixer_paths.xml and mixer_paths_mtp.xml to normal values, so that it was loud enough and did not clog the speaker and headphones. The standard value 78 is changed to 88 (it starts wheezing to 90)
Modified files tested on mido (RN4x), MiuiPro 7.12.14, Lenovo tab3 8 plus (6 android).
On other devices, backup and at your discretion.

Way to edit sound files:
etc / mixer_paths_mtp.xml
etc / mixer_paths.xml
way
that
Working conditions: -required ROOT;
- after changes, check file permissions -rw-r - r--
-values ​​do not exceed 90 (there will be sound distortion), I recommend 86-88;
-checked on firmware Miui 9, the device MIDO (RN4x);
-do not forget about backup, when restoring the system folder is enough
Designation of values: RX1 / RX2 - right, left channel headphone volume;
Rx3 - bottom speaker;
DEC1 / DEC2 - microphones 1-bottom, 2-top;
handset - conversational speaker.
Enable Hi-Fi (Dolby): In our phones there is a built-in DOLBY. To enable, you need to change the value of "NORMAL" to "HIFI" in the files mixer_paths_mtp.xml and mixer_paths.xml in the line on the screen (it is in the top of the files) and you will be pleasantly surprised;
Without the inclusion of "NORMAL" - the sound will be ringing. If you turn on "HIFI", then as in DolbyAtmos, the bass will be added, so that to your taste. When testing, added value only in mixer_paths_mtp.xml and the sound changed, but most likely you need to change in both.
Replaced values ​​in file lines: P.S. In the firmware, the standard values ​​are 78 and 84, but it is clearly not enough on MIDO (in the old firmware 84 in the new 78). I noticed because I was digging there all the time.
By analogy, you can edit sound files on other models, the values ​​you already know. Just add smoothly, no need to hurry. Restart. Successful firmware!
