Hi Guys,

READ THE THREAD CAREFULLY

So I Have Modded The mixer_paths_mtp.xml File Present On The Resurrection Remix ROM And I Was Able To Enable Dual Speakers While Playing Music.

Just Go To The Links Down Below, Download The File You Want, Replace The Downloaded mixer_paths_mtp.xml To System/Etc And Set Permission To rw-r-r And Then Reboot. For Oreo The Path Is System/Vendor/Etc

Note :
1. Before Doing, Take A Backup Of Your Current mixer_paths_mtp.xml So That You Will Be Able To Go Back To Normal If Something Happens.
2. I Only Tested It With Resurrection Remix 5.8.5 Final ROM. So If You Want To Try It On Other ROMs, First Back Up mixer_paths_mtp.xml Then Download And Replace The File To Root/System/Etc For Nougat. And For Oreo Replace The File To Root/System/Vendor/Etc. Also Don't Forget To Set Permissions And Then Reboot
3. If Your Device Bootloops, I Am Not Responsible, Just Make A BackUp Before Flashing Or Replacing.
4. There's Not Much Difference In Sound Unless You Listen In 100% Sound.
5. The Max Volume MOD Will Increase The Sound Of Front Earpiece And The Difference Is Noticeable. But Use It On Your Own Risk Cause It Pushes The Earpiece Level To Maximum.
6. I Am Not Responsible If You Damage Your Front Earpiece

Drop Your mixer_path_mtp.xml From System/Etc If You Want Me To Make It For The ROM You're Using.

Working On : Resurrection Remix, AEX
Working Alongside Viper And Dolby, Oreo, MiUi 9

Leave A Reply If This Worked On Other ROMs Too..

Gr8 but I doubt it can damage earpiece cz it's designed for playing low sound only

Yes.. That's Why I Made Two Mods.. One Plays Music And Pushes The Limit Of Speakers And The Second One Plays At A Decent Volume (Will Not Damage).. But I'm Using The Maximum Volume MOD.. Will See Some Days, If Damages, Don't Care.. Have It Under Warrenty ?

Well, it works somewhat. Tried the "normal" version and I have to put the phone up to the ear like I am making a call to hear anything out of that speaker. Holding the phone away, the bottom speaker overshadows the output of the front speaker completely, could just as well be off.

I did not try the max version, because I am a little chicken :)

I am using the changes for low call volume / low volume on video recording from this forum. I checked for possible conflicts, but they should not interfere if I am not mistaken. https://forum.xda-developers.com/redmi-note-4/how-to/fixed-bad-audio-videos-finally-t3625069

Well, Try The Max MOD Someday ;) . I Have Just Seen The Link You Given.. In My MOD, I Just Changed The Music Output Speaker Values.. As I Saw His YouTube Video, He Modified Only Earpiece Volume And Added More Line.. I Think You Can Follow His Guide On My mixer_paths.xml And Enjoy The Both MOD I Guess :)
