Are you running the stock global ROM and you've noticed that even at max volume the headphone jack output is too low? Here's how to fix it.

For some reason Xiaomi uses different mixer settings between global and China ROMs. The ones in China ROM give you substantially louder volume output.

Those settings are stored in 3 files:
/system/etc/mixer_paths.xml, /system/etc/mixer_paths_i2s.xml, and /system/etc/mixer_paths_tasha.xml (I think that only the last one is actually used by the system, but I didn't check it). To fix the audio volume problem you have to extract those files from the China ROM and overwrite the ones on your /system/ partition. Then you just need to reboot and done.

Here are those files from China stable ROM 8.1.3.0: https://drive.google.com/drive/folde...lU?usp=sharing

This works for the Mi Max as well, albeit using a different filename.
