Increase Headphone Volume on Mi4 CM12.1

Hey guys,

I am using my Mi4 for about 2 1/2 months now and was very unhappy with the low headphone volume of the Mi4 even while running CM12.1 (I almost sold it)

I tried several methods I found here, but most of them did increase volume and overdrive massively at the same time.
Today I more or less found out, that it is only necessary to change one value in the mixer_paths.xml to increase volume and keep overdrive minimised.
Root and a rootexplorer is required! (I did it with CM12.1 so I can't give info about other rootexplorers and permissions)

I recommend doing a backup of your mixer_paths.xml!

Go to /system/etc and open mixer_paths.xml and open it with Editor. (I highly recommend the stock one!)
Scroll down to <path name="headphones">
Increase the value of "TI PA Gain" and save it (if you aren't already, you will be asked to change to root permissions for that)
I'm at 53, which is quite really loud already, so I'm gonna stay there. :fingers-crossed:

Reboot and enjoy.

I am not responsible for any damage to your ears or your phone because you blew up your headphones or your headphonejack. Stay safe guys ;)
