How to increase volume on Xiaomi: from standard settings to hidden features

Owners of Xiaomi devices often face the problem of not loud enough sound – whether it is quiet calls in a noisy room, weak sound in headphones or barely audible speaker while watching videos. The reasons can lie both in hardware limitations (for example, weak speakers in the budget models of Redmi) and in the software limits that MIUI imposes “for the safety of the user”.

In this article, we’ll look at all the possible ways to increase volume on Xiaomi smartphones, tablets and TVs, from basic settings to advanced methods using engineering menus and third-party utilities. It’s important to understand that some methods can damage speakers when used uncontrolled, so we’ll outline the safe limits for each method, and you’ll learn how to get around the limitations of MIUI 14/15 and why standard methods don’t work on some models (such as Xiaomi 13 Ultra or POCO F5).

If you're looking for a solution for a particular model, use the article search (Ctrl+F) with the device name. We've gathered up-to-date data for the Redmi Note, POCO, Xiaomi Mi and Xiaomi Pad lines, as well as for Mi TV and Redmi Smart TVs. Let's start with the simplest and safest ways.

1. Standard volume settings in MIUI

Before resorting to radical methods, check the basic parameters of the system. there are several hidden options in MIUI that can significantly improve the sound without risking the device.

Open Settings → Sound and vibration. Here, pay attention to the following points:

  • 🔊 Media amplification: Enable the "Improving Sound" option (available on Redmi Note 12 and later) which automatically adjusts frequencies for clearer sound.
  • 🎧 Headphone settings: If you use wired or Bluetooth headphones, select the Music or Movie profile to enhance bass.
  • 📱 Volume separation: In some firmwares, you can separately adjust the volume for multimedia, calls and alarms.
  • 🔕 Don’t disturb: Make sure this mode is turned off – it can jam notifications.

On Mi TVs, the path will be different: Settings → Sound → Sound modes. Select Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode Mode

⚠️ Attention: On devices with MIUI 14+ After the update, the "Improving Sound" setting may reset. Check it after each firmware update.

2. Engineering menu: how to unlock hidden sound settings

The Engineering Mode allows you to manually adjust the settings of speakers, microphones and amplifiers, a method that works on most Xiaomi smartphones, but requires caution – incorrect values can lead to burnout of the speaker.

To open the engineering menu:

  1. Open the Phone app.
  2. Enter the combination: ##36446337## (for MIUI 12-15) or #4636## (universal code).
  3. Go to the Hardware Testing → Audio section.

In the Audio menu, you are interested in the following options:

  • 🔊 Max Vol: maximum volume for different types of sound (media, calls, headphones) The default values are usually 80-100 - you can increase to 120-130, but not higher!
  • 🎛️ Headset Gain: Headset Gain amplification for headphones. Optimal value is 5-7 (default 3-4).
  • 📱 Speaker Gain: amplify for built-in speaker. Increase gradually by testing the sound after each step.

For Mi TVs, the engineering menu opens via the remote: press Menu → Settings → All Settings → Device Preferences → About → Press 5 times on Android TV OS Version. From the menu that opens, select Audio → Speaker Test and adjust the Volume Gain setting (maximum +6 dB).

What happens if you put the maximum values in the engineering menu?
If you exceed the safe thresholds (for example, Max Vol = 150+), the speaker begins to distort the sound, and with prolonged load can burn out. On Xiaomi TVs, the risk is lower due to built-in protection, but the sound will become hoarse at high frequencies.

3. Apps to amplify sound: top-5 tested utilities

If standard methods didn't work, you can use third-party applications, and we tested dozens of utilities and selected those that don't require root rights and are compatible with MIUI.

To install ViPER4Android on Xiaomi without root, you will need:

  1. Download modified APK for MIUI.
  2. Install via ADB with the command: adb install --bypass-low-target viper4android.apk
  3. Enable sound processing in the application settings.

⚠️ Note: Apps like Volume Booster may conflict with system services MIUI. If after installation the sound is lost - restart the device and reset the settings of the application.

Hardware methods: cleaning speakers and replacing the grid

If the software methods failed, the problem may be physical contamination of the speakers: dust, pile or moisture over time reduce the volume by 20-30%, especially for models with a lower speaker (Redmi Note 10, POCO X3).

To clean the speaker:

  1. Turn off the device.
  2. Use a soft brush (for example, for drawing) or a compressed air balloon.
  3. To remove moisture, place the smartphone in a silica gel bag for 12 hours.

On Mi TVs, a common problem is a dust-filled acoustic grid to clean it up.

  • 🧹 Shut the TV off the grid.
  • 🔧 Carefully remove the net (it is attached to latches or bilateral tape).
  • 💨 Vacuum the speakers at minimum power or use a sticky roller for clothing.

If the sound has not improved after cleaning, check the integrity of the speaker using the test:

In the engineering menu, select:


Hardware Testing → Audio → Speaker Test




If the sound is intermittent or absent, the speaker is damaged.

💡

For Xiaomi 12T and POCO F4 models with stereo speakers, check both speakers separately. Often, a quiet sound is associated with the failure of one of them.

5. Firmware and modifications: risky but effective ways

For advanced users willing to take risks, there are methods to modify system files, which give maximum amplification of sound, but require unlocking the bootloader and can be deprived of warranties.

Method 1: Editing mixer_paths.xml

This file contains volume limits for all audio devices.

  1. Get root rights (for example, through Magisk).
  2. Download Root Explorer.
  3. Cross the path. /system/vendor/etc/mixer_paths.xml.
  4. Find the lines with max-volume and increase the values by 20–30%. For example: <path name="speaker"> <ctl name="RX1 Digital Volume" value="85" /> → change to 110</path>
  5. Save the file and restart the device.

Method 2: Castom firmware

Some custom firmware (e.g. Pixel Experience or LineageOS) remove the volume limits of MIUI.

  • 🔄 After the firmware will have to configure the device from scratch.
  • 🔒 There may be problems with the camera or sensors (especially on the Redmi). K50).
  • 📱 The guarantee will be cancelled.

⚠️ Note: On devices with MediaTek (e.g. Redmi) 10C or POCO M5) editing mixer_paths.xml This can cause you to lose sound completely!

💡

Changing system files maximizes sound amplification, but requires technical skills, and for most users, standard settings or applications like Volume Booster are enough.

  • 🔄 Reset the sound settings to factory.
Why is POCO F5 not powered by the engineering menu?
On devices with a Snapdragon 7+ Gen 2 processor (including the POCO F5 and Redmi K60), Xiaomi has blocked changing the Max Vol settings in the engineering menu at the software level, the only way out is to use applications like Volume Booster or get root rights.

Can I turn up the volume on Xiaomi without root?
Yes, most of the methods in this article don't require root rights. Start with standard MIUI settings, then try apps like Volume Booster or Equalizer FX. The engineering menu is also available without root, but be careful with the settings.
Why did the sound turn hoarse after the volume in the engineering menu?
That means you've exceeded the safe limit for a speaker: put Max Vol or Speaker Gain back 10 to 15 percent below the maximum. If you're left wheezing, the speaker could get damaged. On Mi TVs, wheezing can occur because of the Dynamic Volume option.
How to increase the volume of the alarm clock on Redmi Note 11?
On Redmi Note 11, the alarm clock volume is adjusted separately. Go to Settings → Sound and Vibration → Alarm Volume. If the maximum is not enough, use third-party alarms (such as Sleep as Android) that allow you to set the volume above the system.
Is it safe to use ViPER4Android on Xiaomi 13 Pro?
On the Xiaomi 13 Pro with Snapdragon 8 Gen 2 ViPER4Android works stably, but requires proper installation through Magisk. The main risk is a conflict with system audio drivers, which can lead to sound loss before flashing.
Why is the sound quieter on the Mi TV 4S than on the Mi TV Q2?
The Mi TV 4S series has 8W (2×10W vs. Q2) speakers. Hardware cannot increase volume, but you can improve the sound through settings: Turn on Movie Mode in the sound settings. Connect the external sound bar via HDMI ARC. Use an equalizer to amplify the average frequencies (500–2000Hz).
