[GUIDE] Increase Your Headphone Volume

[Dazed No More]

If you are like me and like your music loud then you are also pretty disappointed with the low headphone volume of this model phone. V4A and Atmos improve things a little but even with them the volume is lower than most phones are factory stock. Alsa Mixer works to increase the gain from 12 to 15 (max) but only temporarily so I spent this morning finding a way to manually edit the mixer paths for a more permanent solution, which after searching all over had yet to find. Im no developer so it took me a while to find what I was looking for and was surprised to find out there's no less than 8 files that reference headphone L and R gain but I gave it a shot and now the volume is much better than it was.

I have attached a zip with the edited mixer_paths and mixer_volumes to save the time and trouble of going through all the files individually as I did. Just goto /product/etc/audio/hissc/ and copy/backup each of the following files to somewhere on your internal storage or SD card :

mixer_paths_BERLIN.xml
mixer_paths_hi6250.xml
mixer_volumes_BERLIN_ce.xml
mixer_volumes_BERLIN_cmcciot.xml
mixer_volumes_BERLIN_gcf.xml
mixer_volumes_BERLIN_normal.xml
mixer_volumes_BERLIN_unicomiot.xml
mixer_volumes_BERLIN_hi6250_normal.xml

Once you have made copies then move the files from the zip to this directory and change the permissions to rw-r-r with a file manager of your choice. Restart your phone and enjoy your music 20% louder all the time.

*This is only for headphone volume.
**I don't know if other builds are different but it works on B360

Nice, I'll test this as I'll have time! Sometimes i just think: "if only it was louder..." so i hope to gain some after this one

Please elaborate ,bro all messed up tells me nothing. What exactly is wrong? Are your permissions set correctly for the 8 files once you copied them to the correct location? If the instructions were followed it should work fine.

The only things that have been changed in all files are the values of HISSC_SMT_HSL_GAIN and HISSC_SMT_HSR_GAIN from 12 to 15, just like alsamixer does however this is permanent. In both of the mixer_paths files the strings are found only once, in the 6 mixer_volumes files I only changed the values under media-headphones and media-headset.

Nice, i will try
Can you explain me "and change the permissions to match those you just renamed, rw-r-r."
Thanks!

Always have a backup of original files before copying pasting anything. OP has shared the file though but it may not be the case all the time so always have a backup plan

You need to use a root explorer (like MiX, Total Commander, ecc.) to reach the folder listed in OP (/product/etc/audio...) and then modify the permissions of the new copied files to allow them to correctly works (long press on a file and then click on modify permissions -> flag the permissions as stated by OP, there will be dedicated boxes to click on)

Thanks for the explanation. Just a heads up to anyne using ES file manager the permissions are under properties when you long press on a file.

I followed instructions but after copy and pasting the files when i went to permissions it says they are already at rw-r-r Does that sound normal? I used Root Explorer Classic from JRummy Apps. I tried first with X-Plore but it gave me an error that I am not allowed to change the permissions or something like that. But regardless they all show it as rw-r-r before I did any modifications whatsoever

I rebooted but volume does not seem very much different. Its still not loud enough for me, when I get drunk I like to hear the music REALLY loud for head-banging
