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

Have you ever encountered a situation where the sound on your Xiaomi smartphone is too quiet despite the maximum volume level? This is a common problem, especially on budget models or after a firmware update. The reasons can vary from the software limitations of MIUI to the hardware features of the speakers. Fortunately, there are several ways to increase the volume, both through standard settings, through hidden features or third-party tools.

In this article, we will look at all possible methods, from simple to advanced. You will learn how to adjust sound through Settings → Sound, activate hidden options in the engineering menu, use applications to increase volume and even physically improve sound quality. It is important to understand that some methods can affect the life of the speakers or sound quality, so we will explain the risks in detail and give recommendations for safe use.

If you own a Redmi Note 12, a POCO X5, a Xiaomi 13 or any other MIUI 14/15 model, this guide will suit you. Even if your smartphone is not new, there is always a chance of getting it back to the voice, so let's start with the simplest and gradually move on to more complex solutions.

Standard MIUI sound settings: what can be changed without risk

Before you resort to radical measures, check the basic settings. Often users are simply unaware of all the features that MIUI offers. For example, in recent versions of the firmware, there is a separate volume controller for multimedia, alarm and notifications, which can be set independently of each other.

Open Settings → Sound and vibration. Here you should be interested in the following options:

• 🔊 Multimedia volume is the main regulator for music, video and gaming. Try to push the slider to maximum and check the sound.
• 🔔 Notifications and alarms are separate settings for system sounds, sometimes they get lost after updates.
• 🎵 The equaliser is a built-in frequency setting tool. Try to turn on Bass or Rock mode, which can visually increase the volume by amplifying low frequencies.
• 🔇 Do not disturb – make sure this mode is turned off or configured correctly (e.g., does not block the sound of manually selected applications).

Also, look at the Adaptive Sound option (available on some models), which automatically adjusts the volume to the noise level in the room. If the function is on, try turning it off, because sometimes the algorithm is not working correctly and lowers the sound.

⚠️ Warning: If the sound becomes distorted or wheezing after the setting changes, return the equalizer parameters to their original state. Excessive low frequency amplification can damage speakers at long listening intervals.

2. Engineering menu: hidden volume settings for power users

If the standard settings didn't work, you can try changing the sound settings through the Engineering Mode, a hidden section that allows you to fine-tune the hardware components of the smartphone, including the speakers. Careful: the wrong actions here can cause the audio system to crash or even fail.

To open the engineering menu, follow the following steps:

1. Open the Phone app.
2. Enter the combination: ##36446337## (or #4636## on some models).
3. Select the Hardware Testing → Audio section.

And inside, you'll see some tabs with settings.

• 🔈 LoudSpeaker Mode – you can increase the maximum volume level of the speaker. Try setting Level 5 or Level 6 (the default is usually Level 0 or Level 1).
• 🎧 Headset Mode is a similar setting for headphones. Be careful: too high can damage hearing!
• 🔄 Normal Mode is a general audio setting, and you can adjust the balance between the left and right channels if the sound is uneven.

When you change the settings, press Set and restart your smartphone. If the sound is better, great! If there's any distortion or crack, return the settings to their original state.

3. Apps to amplify sound: top-5 utility

If you don't want to go through the settings or take risks with the engineering menu, you can use third-party apps. They work in different ways: some just amplify the sound software, others optimize the output for the speakers, and we tested dozens of utilities and selected the most efficient and safe ones.

The most powerful solution on the list is ViPER4Android, but installing it requires superuser rights. If you don't have root, start with Volume Booster or Equalizer FX. Remember, any app that amplifies sound can shorten the life of speakers when used long-term at maximum volume.

💡

Before installing applications to amplify the sound, back up the current equalizer settings in MIUI. It is enough to take a picture of the screen with the settings or write the values in a notebook.

4. Physical ways to improve sound: covers, stickers and not only

Sometimes the problem with quiet sound is not the software settings, but the design of the smartphone itself, and for example, many Xiaomi models have speakers on the bottom edge, and they can be easily covered with your hand or table surface, and simple physical solutions can help.

• 📦 Acoustic neckline case -- many cheap cases overlap the speakers. Choose a model with precisely cut holes under the audio jacks.
• 🔊 Resonator stickers are special stickers on the speaker that amplify sound waves, sold on AliExpress or in accessories stores.
• 🪑 Position of the smartphone – when watching a video or listening to music, put the phone up with the speaker or use a stand.
• 🧹 Clean speaker - dust and dirt can drown out sound. Carefully clean the holes with a soft brush or compressed air.

You should also look at Bluetooth speakers or headphones. Modern Xiaomi models support aptX or LDAC codecs that deliver high-quality sound without loss. If you want loud and clear sound, you might want to invest in external acoustics.

⚠️ Warning: Don't try to disassemble your smartphone to clean speakers if you don't have experience. Damage to the speaker membrane will lead to complete loss of sound.

5. Firmware Update and Settings Reset: When It Helps

Sometimes the silent sound is caused by software failures or firmware errors. If the problem occurred after the MIUI update, try the following steps:

1. Check the current firmware version in Settings → About Phone → MIUI version. If an update is available, install it.
2. Reset the sound settings: go to Settings → Annexes → Application management → Settings (⚙️) → Reset settings and select Reset sound settings.
3. If nothing helps, do a full reset to factory settings (don’t forget to back up the data!).

Some models (such as Xiaomi 12T or POCO F4) reset the equalizer settings after major updates, check if it ticks on the Quiet Mode or Night Mode option.

If the sound is gone after the update, there may have been a firmware installation error.

Check if the sound is turned off by the hardware button (on some models).

Connect the headphones – if there is sound in them, the problem is in the dynamics.

Reset via Recovery Mode (press Power + Volume Up when turned on).

Contact the service center if nothing helps.-->

6 Root access and system modifications: for advanced users

If you're willing to take drastic measures and have experience with root rights, you can try changing the system files responsible for limiting volume, a method only suitable for experienced users, as improper actions can lead to a "brick" of the device.

Here's what we can do:

1. Get root access with Magisk or SuperSU.
2. Install a file manager with root support (such as Root Explorer).
3. Cross the path. /system/etc/ and find the file. mixer_paths.xml (or similar, depending on the model).
4. Open the file in the text editor and find the lines with the parameters speaker_volume or max_volume.
5. Increase the values by 20-30% of the original values (no more!) and save the file.
6. Reboot your smartphone.

Example of a change in the parameter (before and after):

<path name="speaker">


<ctl name="PRIMARY_MI2S_RX Volume" value="84" />




</path>

<path name="speaker">


<ctl name="PRIMARY_MI2S_RX Volume" value="100" />




</path>

⚠️ Warning: Changing system files can cause your smartphone to run unstable or lose warranty.Always back up your original files before editing. Also note that on some models (for example, with the Snapdragon 8 Gen 2 processor), such modifications can cause the audio chip to overheat.

💡

Before obtaining root rights, make sure that your Xiaomi model is able to unlock the bootloader. On some devices (such as the Chinese versions), this can be blocked by the manufacturer.

7 Hardware malfunctions: when without service can not do

If none of these methods worked, it may be a hardware malfunction, and here are the most common reasons for silent or absent audio on Xiaomi:

• 🔧 Dynamic damage - mechanical impact (fall, moisture) or wear over time.
• 🔌 Contact oxidation – often occurs after moisture or prolonged use in humid climates.
• 🔊 Audio chip malfunction is a rare but critical failure requiring replacement of the motherboard.
• 📶 Problems with antenna module – on some models, sound and communication are controlled by a single chip.

How to diagnose a hardware malfunction:

1. Connect headphones – if there is sound in them, the problem is in the speaker or its connection.
2. Call your smartphone from another phone – if the person you are talking to hear you and you are not, the microphone or speaker is to blame.
3. Check the sound in Safe Mode (press the power button → Safe Mode). If the sound appears, one of the installed applications is to blame.

The cost of repairing a speaker in the service center Xiaomi usually ranges from 800 to 2500 rubles, depending on the model. If the smartphone is warranty, do not try to repair it yourself - this will void warranty obligations.
