[GUIDE] Increase sound in custom ROMs in Redmi Note 4

[LordArcadius]

Hello Redmi Note 4 users! I saw many people complaining about sound in custom ROMs. Yes! I too agree that we do have low sound on custom ROMs compared to the stock MIUI ROM. But you know what! We can easily increase the sound output of our device in custom ROMs. So lets begin.

* Please do some research before flashing it! 
* YOU are choosing to make these modifications, 
* If you point the finger at me for messing up your device, I will laugh at you.[/SIZE][/CENTER]

Requirements

• Root (Flash Magisk or SuperSU)
• Any root explorer (Solid Explorer, ES File Explorer, Root browser etc)
• Little common sense

Instructions
In this tutorial I am going to use ES File Explorer as it is free and easy to use.

• Open ES File explorer and slide out the sidebar from left.
• Turn on Root explorer & Grant root permission
• Now go to root>system>etc
• You will find a file named mixer_paths_mtp.xml, just open it with the ES editor.
• Scroll down a little bit and try to find the below lines.
  

  <ctl name="RX1 Digital Volume" value="84" />
  <ctl name="RX2 Digital Volume" value="84" />
  <ctl name="RX3 Digital Volume" value="76" />

• Now we have to change the value in <ctl name="RX3 Digital Volume" value="76" /> As you can see the default value is 76, we can increase it upto 100 but it will surely going to RIP your speakers. The suggested values is between 80 - 90. I personally use 86 because it gives me loud enough sound without any distortion.
  

  <ctl name="RX3 Digital Volume" value="76" />

• After increasing the value on <ctl name="RX3 Digital Volume" value="86" /> it should look like below code.
  

  <ctl name="RX1 Digital Volume" value="84" />
  <ctl name="RX2 Digital Volume" value="84" />
  <ctl name="RX3 Digital Volume" value="86" />

• Now just save the changes and reboot your device. And now you will definitely notice much louder sound than before.

How to increase call and mic volume?
The sound recorder app records so low. The recordings volume is so low even with full volume.

need to know which rom you are you using. I think I can help you

Stock MIUI, just was wondering what was the role of each of these

 

[asusm930]

Stock MIUI, just was wondering what was the role of each of these

if i recall correctly, they both do the same job. MIUI devs simply made both files because they didnt know which file should be used (not sure myself). On custom roms, the mtp file is the one that matters and custom roms only have the mtp one

for now, just edit both files

If I did this and it ****ed up (media refuses to play) will dirty flashing my ROM fix it?

[amit.tiger12]

Ok but I was talking about increasing Low LEVEL (means at Level 1) volume on device for headphones, and was not talking about increasing OVERALL volume..
Can you confirm this??
