How to Increase Maximum Volume on Xiaomi: From Standard Settings to Hidden Features

Have you ever encountered a situation where even at full volume, music or video on your Xiaomi sounds too quiet? This is a common problem — especially in Redmi Note, POCO or budget lines, where the manufacturer artificially limits the power of the speakers. But the good news is that you can increase the maximum volume — and it doesn't always need root rights or complex manipulations.

In this article, we will examine the 7 proven methods, from simple settings in the MIUI to working with the engineering menu and modifying system files. Importantly, not all methods are equally safe. For example, changing the parameters in the mixer_paths.xml can lead to audio distortion or overheating of speakers, and using third-party applications sometimes conflicts with system updates. So we will describe the risks of each option in detail and give recommendations on how to minimize possible harm.

Before you start, check if the quiet sound is a result of a hardware problem. A clogged speaker grille, a damaged membrane, or a faulty headphone jack can mimic software constraints. If there is a problem after cleaning and restarting the device, read on.

1. Standard MIUI settings: what can be squeezed without risk

Let's start with the safest one, the built-in MIUI tools, and what many users don't know is that even standard firmware has hidden options for improving sound.

The first thing you should do is turn off the volume limit for the EU (if your device was sold in Europe), which is a local limit, but can be bypassed:

1. Go to Settings → Sound and vibration → Additional settings.
2. Find Volume Limit (or Safe Volume in newer versions of MIUI).
3. Turn off the slider or select No Limits option.

If there is no such item, try to change the region of the system to India or the Global version (without reference to the EU).

• 📱 Open the Settings. → The phone.
• 🔄 Press 5-7 times on Version MIUI until a developer mode is notified.
• 🌍 Go back to the main settings, find a new Developer section, and select Region (or Region).
• 🇮🇳 Install India and restart the device.

💡

After changing region, check for updates in Settings → About Phone → System Update. Sometimes new firmware versions with advanced audio settings appear.

Another little-known trick is to enable multimedia amplification, and in some versions of MIUI (especially on the POCO F3, Redmi Note 10 Pro), this parameter is hidden to activate it:

1. Install the Substratum Theme Engine app (Magisk is required for full-time operation).
2. In the theme settings, look for the AudioFX or Mi Sound Enhancer option.
3. Activate the Boost Media Volume slider (if any).

2. Engineering menu: hidden parameters of sound

The Engineering Menu (or Engineer Mode) is a service software that allows you to change low-level device settings, including audio settings. On Xiaomi models with Qualcomm processors (for example, Redmi Note 11 Pro+, POCO X4 Pro), this menu gives you access to speaker and microphone amplifiers.

To get there:

• 📞 Open the phone application.
• 🔢 Enter the combination: ##36446337## (or #4636### for older models).
• 🔊 Select the Hardware Testing → Audio tab.

In this section you are interested in the following parameters:

Backup data |Write down the current parameters |Use the charger (do not drain the battery below 50%)|Do not exceed the recommended values by more than 20%-->

Warning: Changing Speaker Gain values above 160 can cause physical damage to the speaker. On dual-speaker models (e.g. Xiaomi 12 Pro), increase the volume the same for both, otherwise the sound will be imbalanced.

If the sound is hoarse or has been disturbed, return the standard values and restart the device, and in some cases, resetting the audio settings through the same Engineer Mode (Audio → Reset tab) helps.

3 Modification of mixer_paths.xml: for advanced users

The mixer_paths.xml file is a configuration document that defines how the system manages the sound streams. By changing it, you can remove the software volume limits, but this requires root rights and caution. An editing error can result in complete loss of sound.

Here's how to do it:

1. Install Magisk and get root access (see XDA Developers for instructions for your model).
2. Download a root-enabled file manager (such as Root Explorer or FX File Explorer).
3. Click on the path: /vendor/etc/mixer_paths.xml (or /system/vendor/etc/ on some firmware).
4. Make a backup copy of the file (copy it on the SD-map).
5. Open the file in the text editor and find the lines with the parameters: <path name="speaker"> <ctl name="RX1 Digital Volume" value="84" /> <ctl name="RX2 Digital Volume" value="84" /> Increase the value values by 10-15 units (for example, from 84 to 95).
6. Save the changes, set the rights 644 (rw-r--r---) and restart the device.

For different Xiaomi models, paths and parameters may differ. For example, on the POCO F1 you need to edit mixer_paths_tasha.xml, and on the Redmi Note 9 Pro you need to edit mixer_paths_joan.xml.

Attention ⚠️ On devices with MediaTek (e.g., Redmi 10A, POCO M4 Pro), editing mixer_paths.xml is often blocked by the SLA (Secure Boot) system, in which case only custom firmware with signature verification disabled will help.

4. Apps to amplify sound: top-5 tested

If you don't want to go through system files, you can use third-party applications. They work in different ways: some amplify the sound programmatically (via equalizer), others modify the audio stream at the driver level, and we tested 15 applications and selected the most effective ones for Xiaomi.

Here's our rating:

1. ViPER4Android FX (requires Magisk): 🎛️ Full control of equalizer and amplifier. 🔊 Supports profiles for different genres of music. ⚠️ Complex setup for beginners.
2. Volume Booster GOODEV (no root): 📈 Increases volume to 200% of standard. 🎧 Works with headphones and speakers. ⚠️ Can cause distortions at maximum values.
3. Equalizer & Bass Booster (from Smart Android Apps LLC): 🎵 Built-in 10-band equalizer. 🔋 Low battery consumption. ⚠️ Advertising in the free version.
4. Precise Volume: 📉 Allows you to adjust the volume more accurately (step 1% instead of 5%). 🔄 Compatible with most Xiaomi models. ⚠️ Does not work on MIUI 14+ without additional rights.

Wavelet

ViPER4Android

• 🎧 Optimized for headphones.
• 🔊 Automatically correct the sound to your device.
• ⚠️ Requires Magisk for full functionality.

Before installing any app, check it’s compatible with your Xiaomi model. For example, ViPER4Android may not work on Android 12+ devices without additional patches. Also pay attention to reviews – some apps (such as Volume Booster Pro) contain aggressive advertising or collect data.

💡

The best choice for most users is the Equalizer & Bass Booster, which requires no root rights, has a simple interface and minimal risks to the system.

Attention ⚠️ Apps that promise to increase volume by 2x or 300% often simply distort the sound by adding clipping, which can damage the speakers over long periods of use. Optimal amplification is no more than + 30% of the standard level.

5.Castom firmware: when standard methods do not help

If you've tried all of these, but the volume still doesn't work, the radical option is custom firmware. Some builds (e.g. Pixel Experience, LineageOS, ArrowOS) have modified audio drivers with extended volume limits.

Here’s what you need to know before the scalp:

• 🔧 Requires an unlocked bootloader (Bootloader) and TWRP Recovery.
• 📱 Supported models: Redmi Note 10/Pro, POCO F3/X3, Mi 11 Lite, etc. (see LineageOS Wiki for a full list).
• ⚠️ Risks: loss of warranty, possible bugs (failure to work) NFC, camera.).
• 🔄 After the firmware will have to configure the device from scratch.

The process of installing custom firmware on Xiaomi looks like this:

1. Unlock the bootloader through the Mi Unlock Tool (it may take 7-15 days to wait).
2. Install TWRP Recovery for your model (see instructions in XDA or 4PDA).
3. Download firmware (e.g. Pixel Experience) and GApps (if you need Google services).
4. Download to TWRP (Power + Volume Up buttons) and make Wipe (Dalvik, Cache, System, Data).
5. Install firmware and GApps, then restart.

After installation, check the volume in the sound settings. Custom firmware often has additional options, such as:

• 🔊 Sound Gain Control is a manual gain setting.
• 🎛️ Audio Mods are modified drivers from ViPER4Android.
• 🔋 Battery Friendly Mode is a power-saving sound optimization.

Attention ⚠️ On some devices (e.g. Xiaomi 12T), custom firmware may block the main camera from operating because of closed drivers. Check user reviews of your model before installing.

Hardware modifications: when software methods are powerless

If none of the software methods worked, the problem could be the hardware, and here are the most common reasons for quiet sound and its solution:

The most common problem is dust and debris in the dynamics, so you can clean it yourself.

1. Turn off the phone and remove it. SIM-map.
2. Use a can of compressed air (keep at a distance of 5-10 cm).
3. For persistent contaminants, gently walk with a soft brush (for example, for drawing).
4. Do not use sharp objects – it can tear the membrane!

If the speaker is physically damaged, it can be replaced. On AliExpress or service centers, they sell original and similar parts. For example, the speaker for the Redmi Note 8 Pro costs about 800 ₽, and for the POCO X3 NFC it costs 1,200 ₽. Installation in the service will cost 1,000-1,500 ₽.

💡

Before replacing the speaker, check it for performance using a test in the engineering menu (#06## → Audio Test). Sometimes the problem lies not in the dynamics, but in the plume or motherboard.

7. Alternative solutions: if nothing has worked

If all attempts to increase the volume have failed, consider alternative options:

Use external speakers or headphones:

• 🔊 Bluetooth speakers (e.g., Xiaomi Mi Portable Speaker) – volume up to 10W.
• 🎧 Headphones with an amplifier (e.g. 1More Triple Driver).
• 🔌 Active columns via USB-C → 3.5 mm adapter.

Set up the equalizer to improve your perception:

Sometimes the problem is not the volume, but the frequency response, so if you're missing the low frequencies in the music, for example, the sound seems quieter, and then the equalizer will help.

• 🎛️ In MIUI: Settings → Sound → Equalizer.
• 🎛️ In apps: Poweramp, Neutron Music Player.

Recommended settings for bass:

60 Hz: +4 dB


170 Hz: +2 dB




310 Hz: 0 dB




1 kHz: -1 dB




6 kHz: +1 dB

Check the applications for compatibility:

Some programs (e.g. YouTube, Netflix) have their own volume limits to get around them:

• 📺 On YouTube: Install Vanced (there is an option to disable sound normalization).
• 🎬 On Netflix: Turn on High Volume in the app settings.
• 🎮 In games: Check the sound settings inside the game (sometimes there is a separate controller).
