How to increase the volume of the speaker on the Xiaomi phone: from standard settings to the engineering menu

Have you ever encountered a situation where the loudness of speakers on your Xiaomi seems insufficient? You may not hear the other person in a noisy room, the music sounds too quiet, and the system sounds are barely discernible. This problem is especially relevant for owners of budget models Redmi or POCO, where the manufacturer often saves on quality speakers. But don't be quick to blame the iron - in 80% of cases, the volume can be increased software!

In this article, we’ll look at all the possible ways to amplify the sound on Xiaomi smartphones, from basic settings to hidden engineering menu features, how to safely raise the volume without the risk of damaging speakers, which apps really work and which are a waste of time. Particular attention will be paid to models with mono-dynamics (for example, Redmi Note 10 or the Redmi Note). POCO M3), where the problem of quiet sound is particularly acute.

We warn you that not all methods are equally useful, some have temporary effects, others require root rights, and still others can shorten the life of speakers when used poorly, and we will be honest about the pros and cons of each approach so that you can choose the best option for your model.

1. Standard audio settings: what can be done without installing applications

Before digging deeper, check the basics. Many Xiaomi users don't even realize there are hidden volume controls in the system that don't show up on the home screen.

Open Settings → Sound and vibration. Here you should be interested in three key points:

• 🔊 Media volume – regulates the sound in applications (YouTube, Spotify, etc.) Often this slider is on the side of the device. 70-80% default.
• 📞 The volume of the call is responsible for incoming calls and alarm clocks. 9A, POCO C31) This parameter is artificially understated.
• 🛎️ System sounds -- includes notifications, keyboards, and other signals -- often hidden in volume reserve.

Test each slider separately. For example, in MIUI 14, at maximum media, the actual volume can only be 85% of what it can be, try to reduce the volume to 90%, then raise it to maximum again, sometimes resetting the software constraints.

Don't forget to have adaptive sound in the same settings, which automatically adjusts the volume to the noise around you, but sometimes it doesn't work properly, and if you notice that the sound is spontaneously muted, turn it off.

⚠️ Attention: On models with IR-blaster (Redmi Note 11, POCO X3 Pro) the audio menu may have "IR transmitter volume" on it, and don't confuse it with the basic settings, it's only responsible for the remote control.

2. Engineering menu: hidden volume settings

The most effective way to turn up the volume without root rights is to use an engineering menu, which is designed to test the hardware, but allows you to manually adjust the sound levels.

Instructions for MIUI 12/13/14:

1. Open the Phone app and type the combination: ##36446337## (code may not work on new models).
2. If the code doesn’t work, try the alternative: ##4636## → go to Audio.
3. In the Hardware Testing → Audio → LoudSpeaker Mode menu, you will see the Max Vol and Min Vol options.
4. Increase the Max Vol by 5-10 units (no more than 15% of the original!) for mono speakers (Redmi 9C) the optimal value is 140-145.

Important: Changes apply immediately, but they can reset once you restart, so you can fix the settings.

Increase Max Vol by no more than 15%

Check the sound for distortion

Reboot the phone

Repeat settings upon reset

Write down the initial values (in case of rollback)-->

On some models (POCO F3, Xiaomi 11T) the engineering menu is blocked, in which case the MTK Engineering Mode app (MediaTek processor only) will help. Download it from APKCombo, as the original version may not be available on Google Play.

⚠️ Warning: Exceeding the Max Vol by more than 20 units from the factory can cause the speaker to overheat and distort the sound at high frequencies. On dual-speaker models (Redmi Note 10 Pro), adjust each individually!

3.Sound amplification applications: what works and what doesn't

App stores are full of tools like Volume Booster or Super Loud, but 90 percent of them are empty, and we tested popular solutions and only selected those that have real impact.

For maximum effect, combine the Volume Booster GOODEV with the settings of the engineering menu. For example, on the POCO X3 NFC, this combination gives a volume increase of up to 45% without noticeable distortion.

If you want separate left/right speaker control (relevant to the Redmi Note 11 Pro+ with stereo sound), try Samsung's SoundAssistant. Despite its Galaxy focus, it works on Xiaomi as well, allowing you to balance sound between speakers.

💡

Before installing any amplifiers, check if the developer mode settings include "Disable absolute volume." If it's active, the apps won't be able to exceed system limits.

4. Equalizer setting: how to improve sound perception

Sometimes the problem is not volume, but frequency response. For example, on Redmi 9T, the factory equalizer settings cut the low frequencies, making the sound seem quieter, and you can fix this without third-party applications.

How to set up the built-in equalizer:

1. Open Settings → Sound and vibration → Equator.
2. Choose a Bass or Rock preset – they amplify the low and medium frequencies, which subjectively makes the sound louder.
3. Manually lift the sliders 100-300 Hz (for voice) and 2-5 kHz (for clarity).
4. Turn off Adaptive Sound if it interferes with settings.

For advanced customization, use Wavelet (free on Google Play).

• 🎛️ Create custom presets for specific headphones / speakers
• 🔇 Enhance individual frequency bands (useful for voice calls)
• 🎵 Automatically apply settings for different applications

On the POCO F4 GT and other Dolby Atmos models, remember to activate this mode in the audio settings. It doesn't increase the volume directly, but improves the spatial sound, which subjectively makes the perception louder.

5 Hardware limitations: when software methods will not help

If you've tried all of these, but the volume is low, it could be the hardware. Here are the typical hardware limitations.

• 🔋 Weak sound amplifier - typical for budget models (Redmi) A1, POCO C40). Only a replacement motherboard will help.
• 🔊 Contaminated speaker – dust and pile reduce volume by 30-50%. Try to clean the holes carefully with a toothpick.
• 🔌 Damaged plume – if the sound disappears when you press the body, it is a mechanical malfunction.
• 📱 Mikon defect – if the interlocutor can’t hear you, and you are his – the problem in the microphone, not the dynamics.

Check the hardware serviceability of the speaker can be through the test:

1. Enter the phone app ##6484## (Manual Test Mode).
2. Select Speaker and listen to the test signal.
3. If the sound is distorted or missing, the speaker is faulty.

If you are sure of a malfunction, but the phone is warranty - do not try to repair yourself. In Xiaomi service centers, the speaker is replaced by a device that is not designed for the repair of the device. 1-2 day (cost: 800-1500 ₽ model-wise).

6. Root methods: maximum volume for advanced users

For those willing to take drastic measures, there are ways to increase volume by changing system files, which require root rights and are only suitable for power users.

Method 1: Editing mixer_paths.xml

This file contains volume limits for all audio devices.

1. Get root access (for example, through Magisk).
2. Install Root Explorer or FX File Explorer.
3. Move to the /system/vendor/etc/ and find the file. mixer_paths.xml.
4. Then, make sure you have a safe place to go.
5. Open the file in the text editor and find lines with speaker or rx.
6. Increase your max by 10-20% (e.g., from 84 to 95).
7. Save the file, set the rights to 644, and restart the phone.

Method 2: Using Magisk modules

Ready-made solutions for amplifying sound:

• 🔊 Audio Modification Library – allows you to fine-tune the volume for each type of sound.
• 🎵 ViPER4Android FX — full-fledged sound processor with amplifier.
• 🔇 JamesDSP – an alternative to ViPER with support for new Android.

⚠️ Note: On models with Snapdragon processor 8 Gen 1/2 (Xiaomi 12/13 series) editing mixer_paths.xml This can cause you to lose all of your sound.

After rooting, be sure to test the speakers at different frequencies. If you have wheezing or the sound "choking" - reduce the values in the swelling. mixer_paths.xml on 5-10 unit.

7. Alternative solutions: when to increase the volume is impossible

If all attempts have failed, consider alternative ways to improve your sound.

• 🎧 Use external speakers – even the budget Bluetooth speaker (Xiaomi Mi Portable) sounds louder than the built-in speaker.
• 🔗 Connect headphones – on the Redmi Note 12 and later supported LDAC, which gives you excellent sound quality.
• 📱 Activate the "In the car" mode in the call settings - it enhances the voice of the interlocutor by suppressing noise.
• 🔄 Update the firmware - in new versions MIUI Sometimes correcting sound bugs (for example, in the MIUI 14.0.4. POCO X5 Turned up the volume by 15%).

For owners of POCO F5 and other models with Dolby Atmos, we recommend experimenting with sound profiles, for example, Movie mode enhances dialogue in movies, and Music adds bass – this can compensate for low volume.

If you make frequent calls in noisy places, try the Google Phone app (install from Google Play), which has improved voice processing and automatically raises the volume of the interlocutor when background noise.

💡

On mono speakers, it is physically impossible to achieve the volume of the stereo, in which case the external speaker or headphones are the only solution for high-quality sound.
