[GUIDE] How to increase headphone volume

[Indigoeyes]

Hello guys and girls! This tutorial is for those who thinks the P2 has insufficient audio while wearing headphones. Note that I'm not responsible for any damage to your phone or your hearing. Just backup the files and you should be good if you accidentally manage to screw up!

[1] First step is to download a root browser (I used Solid Explorer).
[2] Navigate to /system/etc
[3] Find the file called Mixer_Paths_MTP.xml
[4] Backup the Mixer_Paths_MTP.xml so if you screw up it's just restoring the old file.
[5] Open the file using a xml editor (I used Solid Explorer's own xml editor, this is because Quickedit wouldn't let the values stay after rebooting).
[6] Navigate in the xml document and find the following values= "HPHL Volume", "HPHR Volume", "RX1 Digital Volume", "RX2 Digital Volume", "EAR PA GAIN" (The one without the 1P5 in it) and "RX3 Digital Volume" and increase the values to your liking.
[7] Reboot and enjoy your boosted volume

Optional; Do the same procedure to the file called Mixer_Paths.xml if it doesn't work solely editing Mixer_Paths_MTP.xml

Do you know which control should I modify for a microphone volume boost?

Or just install V4A or Dolby Atmos?? You need root for this of course.

I made a thread earlier about Viper4Android being insufficient in boosting the volume. Hence this guide allows you to boost your sound even further. ?

Thanks for the info.

In step 3 which of the following values do I need to increase?
Thanks

In step 3 which of the following values do I need to increase?
Thanks

RX1 Digital Volume, RX2 Digital Volume, RX3 Digital Volume all which I believe are set to 83 from the beginning and EAR PA GAIN which I believe is set to POS_6_DB from the beginning My personal setting is set to RX1, RX2, RX3 = 93 and POS_15_DB

Does this work even when one uses headphone in conversation to hear the other person? I mean using an headset with headphones and microphone.

 

[pokee2000]

is this working after resetting the phone ?
or u should do it again ?

Well, for me it acutally doesn't work at all @Stock deodexed ROM (s244). Changing any values the aforementioned XML causes the phone to not give me any sound at all - even after rebooting.
Changing the values back doesn't help either, the only way to reset the problem is to reflash or to replace the file with the backed up version. Seems rather strange, but well.

 

[masked__rider]

Phone has to be rooted in order so make changes in the .xml file, right?

 

[THM01]

Yes, because you can't edit the file without root access. You can open and read it, but editing is impossible.

Which file should I modify?
and What data to modify?
Please give me some guidance if you have time，thanks

OK, so one thing I did notice while testing the volume boost (which works fine on Lineage OS) is that the noise floor rises significantly when boosting the volume.
Listening with bigger headphones like my DT880s is possible then, yes, but you notice that the sound lacks body and depth, the amp in the P2 just isn't powerful enough to drive them adequately. I'm usually not someone who believes in audio voodoo, but it is really noticeable here.
And then, In-ears just sound awful because the noisefloor is constantly hearable.
So, in the end I reverted back to the normal state because I listen to In ears way more and the disadvantages outweigh the advantages here IMHO.

It seems nothing comes without a price

Easy way

Flash @Wonder Wicked Witch sound mod
Go to the viper app
Then extra gain enable and do max gain to max
EZ PZ LEMON SQUEEZEE

Could you please send me the file mixer_paths_mtp.xml because I didn't back it up (I know I am fool) and now don't have sound at all... If you do this I own you!

There you go : https://drive.google.com/file/d/1GwSEvJ4yq2pEb1gQWMj0iUoyHXjcsTbm/view?usp=sharing

It's from viper OS (7.1.2) so I hope nothing changed, but I hope it works for you
