How to Make Sound Louder on Xiaomi Phone: A Step-by-Step Guide

Are you tired of the quiet sound on your Xiaomi? Music, videos and calls seem too quiet even at maximum volume? This problem is familiar to many owners of smartphones brand — especially on budget models like Redmi 9A or Poco M3. But don’t rush to blame the speakers: in 90% of cases, the volume can be increased programmatically without resorting to repair.

In this article, we’ll look at all the ways you can go from basic MIUI settings to hidden engineering menus to third-party apps, how to safely turn up the volume without distortion, why some methods only work on certain models, and what to do if the sound is still quiet, and a unique life hack with a customized audio profile via ADB, which is not described in any official Xiaomi instructions.

We warn you right away that not all methods are equally useful, such as changing files. mixer_paths.xml This can damage the speakers on some devices, so we've marked the risky ways with special warnings -- read carefully!

1. Basic volume settings in MIUI

Start with the obvious: check the system audio settings. In MIUI 12/13/14, the interface may be slightly different, but the general logic is maintained. Open Settings → Sound and vibration and notice:

• 🔊 Multimedia volume: regulates sound in games, music, video, and is often reset when the headphones are connected.
• 📞 Call volume is a separate slider for incoming calls. On some models (e.g. Xiaomi) 12T) You can increase it above the maximum through the additional menu.
• 🚨 Notifications and alarms – sometimes the quiet sound of an alarm clock is associated with energy saving restrictions.
• 🎧 Safe Volume Level – Function MIUI, It automatically turns the volume down after a long listening period.

If the sliders are already at their maximum, but the sound is still quiet, try resetting the sound settings to the factory.

1. Go to Settings → System and device → Resetting.
2. Select Resetting Sound Settings (not to be confused with a full phone reset!).
3. Confirm the action and restart the device.

An important nuance: on some devices (for example, Redmi Note 8 Pro) after upgrading to MIUI 14, a separate volume adjustment for the alarm clock disappears, in which case only manual editing of system files will help (for this, see the section about ADB).

2. disabling volume restrictions in EU-firmware

If your Xiaomi is bought in Europe, chances are it has a volume-limited firmware in the EU (maximum 85 dB), a security requirement, but it lowers the maximum volume by a lot.

Method 1: Change the firmware region

The most reliable method is to reflash the phone to the global (Global) or Indian (India) version of MIUI.

1. Download the firmware for your model from the official Xiaomi website (choose Global or India version).
2. Go to Settings → About Phone → MIUI version and tap 7 times on the build number to activate Developer Mode.
3. Return to Settings → Additional → For developers and enable OEM Unlock and USB Debugging.
4. Connect your phone to your PC, launch the Mi Flash Tool and run the downloaded firmware.

Method 2: Editing the build.prop file

A less radical method is to change the region directly in the system file.

1. Install Root Browser or any other file manager with access to system files.
2. Open /system/build.prop file in the text editor.
3. Find ro.miui.region=EU and replace EU with IN (India) or Global.
4. Save the file, reboot the phone.

⚠️ Note: editing build.prop without root rights is impossible on new versions MIUI (13+). If you don’t have root, use the first method with flashing.

3.Use of the Engineering Menu (MTK and Qualcomm)

Each Xiaomi smartphone has a hidden engineering menu where you can fine-tune the sound settings.

After entering the engineering menu:

1. Choose Hardware Testing → Audio.
2. In the LoudSpeaker Mode or Speaker section, find Max Volume or Volume options.
3. Increase your values by 5-10 units (don’t bet the maximum right away!).
4. Save the settings and restart the phone.

💡

If the sound becomes distorted after changes in the engineering menu (wheezing, crackling), return the values to their place and try to increase the volume by 2-3 units instead of 5-10.

A warning for Poco F3 and Xiaomi 11T owners: on these models, changing the PA Gain settings in the engineering menu can cause the sound chip to overheat. If the phone gets too hot when playing the sound after setting up, reset it via ##4636## → Factory Reset.

4.Applicants for sound amplification

If system methods didn't work, try third-party utilities. We tested 15 apps and selected the 3 most effective ones:

• 🎵 Volume Booster GOODEV — It increases volume by 20 to 30 percent through software-based sound processing, works without root, but can cause distortion at maximum volume.
• 🔊 Precise Volume – allows you to adjust the volume in 1% increments (instead of the standard 15 levels in the volume). MIUI). Useful for fine-tuning.
• 🎛️ ViPER4Android — It's an advanced equalizer and amplifier sound driver, requires root or Magisk, but it's the best sound driver.

To install ViPER4Android on Xiaomi:

Download APK from the official website |Install Magisk (if no root) |Activate the ViPER module in Magisk|Reboot the phone |Configure the sound profile in the application

-->

Important: ViPER4Android conflicts with some versions of MIUI 14 (especially on the Redmi Note 11).If the sound is completely lost after installation, remove the module through Magisk and use the Volume Booster GOODEV.

5. Adjusting the sound through ADB (for advanced)

This method requires a computer and command knowledge, but gives maximum control over sound, suitable for all Xiaomi models, including the new Xiaomi 13 and Poco F5.

What you need:

• 🖥️ Computer with installed ADB and Fastboot.
• 📱 Included Debugging by USB phone-on.
• 🔌 Cable USB (preferably original).

Instructions:

1. Connect your phone to your PC and open the command line (Windows) or terminal (Mac/Linux).
2. Enter the command to check the connection: Adb devices should appear the name of your device.
3. Increase the volume of media (values from 0 to 15): adb shell media volume --stream 3 --set 15
4. Use the following: Adb shell media volume --stream 0 --set 15

A unique trick for Xiaomi: to unlock hidden volume levels (above the standard maximum), do:

adb shell settings put global volume_steps 30

This command increases the number of volume control steps from 15 to 30, allowing you to fine-tune the sound.

⚠️ Note: on some models (Xiaomi Mi) A2, Mi A3) team ADB The sound only works after the shutdown. MIUI Optimization in the developer settings. Otherwise, the changes will reset after the reboot.

Hardware problems: when software methods do not help

If you have tried all the methods, but the sound remains quiet, the problem may be in the hardware.

• 🔇 Contamination speaker - dust and pile block the sound holes. Clean them with a soft brush or compressed air.
• 💧 Moisture intake - even after drying, the oxidation of the contacts can turn down the volume.
• 🔌 Drum plume damage is a common problem after falls. Diagnosed at a service center.
• 🔋 Weak Sound Chip – on Cheap Models (Redmi) 8A, Redmi 9C) The chip may not be able to pull high loads.

How to check if there is a hardware problem:

1. Connect headphones – if the sound is loud, the problem is the phone’s dynamics.
2. Record a video with the microphone on and play it back, and if it's quiet but loud, it's the microphone.
3. Call another phone and turn on speakerphone, and if the person is listening to you quietly, the problem is with the microphone or the network.

If the diagnosis showed a hardware malfunction, do not try to fix the phone yourself - in Xiaomi speakers are often soldered to the motherboard. Contact the service center (the cost of replacing the speaker is from 800 to 2500 rubles, depending on the model).

💡

Before visiting the service, back up your data! On some models (Poco X3 Pro) to replace the speaker requires a complete disassembly of the phone, which can lead to a reset.

7. Sound optimization for specific scenarios

Sometimes the sound seems quiet not because of the speaker issues, but because of the incorrect settings for a particular application.

🎮 Games (PUBG, Genshin Impact, Call of Duty)

In games, the sound is often muted because of performance optimization.

• Open Settings → Special permissions → Battery optimization.
• Find the game in the list and turn off optimization for it.
• In the game settings, turn on High Sound Performance (if there is such a item).

🎵 Music (Spotify, YouTube Music, VLC)

For music, it is important not only to increase the volume, but also to improve the sound:

• In Spotify, enable Volume Normalization in the playback settings.
• In VLC, activate the Sound Amplifier (up to 200%) and the equalizer.
• Use Wavelet (sound tuning app) with a preset for your Xiaomi model.

📞 Calls and voice messages

If the person is not listening to you:

• Check if the microphone hole is covered with a cover or finger.
• Enable Voice Improvement in Call Settings (Settings) → SIM-maps and mobile networks → Improving voice).
• For WhatsApp and Telegram, use a headset – voice messages are recorded more clearly.
