[GUIDE] headphone volume boost / increase / fix (both ROOT/noroot)

[hlubepet]

Hi,

-ROOT
if you have root
1. Install QUICKEDIT (free from play store)
2. Open file: /vendor/etc/mixer_paths.xml
3. Search for HPHL/HPHR values (first screenshot) and change the value to 20
4. Search for RX1 digital volume (and RX2... Like on attached screenshots) and change values to 86-88. Dont change values any higher for safety reasons
5. SAVE file, exit Quickedit
6. REBOOT
7. enjoy!

No, this values only changes volume gain via 3,5 jack for headphones. So this will not work for Bluetooth /speaker (internal or external).
If you connect phone via line-in cable to car/speaker aux input, volume will be boosted

Why is Japan louder by default?
Maybe so that the shutter sound will still be heard through the headphones?

Thanks Japan.

I got root on my stock rom MIUI 12.02. I changed the values as recommended (even raised RX1 and 2 to 94) but there is no difference. Still too low volume.
