Hello,

First > sorry for my english :)

The P9 is a wonderfull smartphone but the volume of the headset is very low :(

I have found a solution and i want share with you.

must be already that your phone is root.

With appli Es-explorer, root with 649 (in left menu, tools, root explorer)

go to system/etc/audio/hi6402

found the file mixer_volumes_EVA_ce.xml


and modify this text in ''media-headset''

<ctl name="HPL PGA GAIN'' value="18" />
<ctl name="HPR PGA GAIN'' value="18" />

to

<ctl name="HPL PGA GAIN'' value="30" />
<ctl name="HPR PGA GAIN'' value="30" />


Save and reboot tour phone

Thats ALL

If this modification don't work, modify the files
mixer_volumes_EVA_cmcciot.xml
mixer_volumes_EVA_gcf.xml
mixer_volumes_EVA_normal.xml
