Can't edit mixer paths to increase volume - Android 6.0

Hi,
I recently rooted my Android Marshmallow 6.0 just to increase the headphone volume via Mixer Paths through Es File explorer, I have done this a lot of times on Android Lollipop, but on Marshmallow I can't edit the Mixer Paths anymore. It keeps saying it can't save the file, and it fails to do so. I tried tinkering with ES explorer settings, no luck. Enabled root exploring and such, tried tinkering with SuperSu permissions, still no luck. I set it to Read/Write too.
Am I missing a step here?

I rooted Android Marshmallow through Elementx Kernal, flashed TWRP then flashed both Super Su and the Kernel.
Help would be appreciated,
Thanks in advance.

(Z5 Compact / E5823) Speaker volume lowering itself

Greetings.

Just bought the Z5C. Phone is awesome, but when I play anything over the speakers (incoming call, music, etc.) the volume is good for about a second, and then it turns very silent.
Anyone experienced this, or knows something about the issue?

S6 Edge Plus Headphone Volume Boost & Speaker Volume Boost






So i looked everywhere to make the S6 Edge Plus sounds louder, but i could only find a louder mod for the S6 Edge, so I decided to do a mod myself and share :)

If you want louder music for your headphones or a little louder for the speaker then simply unzip the attached xml file and copy it to system/etc. and change the permissions to -rw -r -r. Restart your phone and enjoy better louder sound :)

Remember, always back up the original mixer_gains.xml,

If you want the sounds lower or louder then edit the mixer_gains.xml input 1 Volume values in the media playback volume section from lines 6

Lines 26 and 27 is the headphone volume values.
