How to Remove Xiaomi’s Sound Limitation: From System Settings to Engineering Menu

Have you ever noticed that even at full volume, your Xiaomi sounds quieter than other smartphones? It's no coincidence that the manufacturer artificially limits the maximum sound level to protect speakers from overload and meet European safety standards. But what if you really need a louder sound - for example, to listen to music in a noisy place or use the phone as a speaker at a picnic?

In this article, we’ll look at all the possible ways to remove the volume limit on Xiaomi, Redmi and POCO devices, from simple settings in MIUI to deep changes in system files. It’s important to understand that increasing volume above factory limits can cause sound distortion or even damage to speakers over long-term use. We’ll show you how to do this safely and what risks you should consider.

The methods in this article are tested on current versions of MIUI 14 and MIUI 15 (including HyperOS), but most of them work on older firmware. If your smartphone model is released after 2020, the probability of success is 90% – modern Xiaomi devices have a similar sound system architecture.

Before we start to “overclock” sound, it is worthwhile to understand why the manufacturer has introduced these restrictions. First, it is the protection of equipment: smartphone speakers have a minimum margin of safety, and exceeding the rated power leads to their degradation (loss of sound quality) or breakage. Second, Xiaomi complies with the European standard EN 50332-2, which limits the maximum sound level in headphones to 85 dB to protect users’ hearing.

In practice, this means:

  • 🔊 Dynamics: Limitation at the level 70-80% It depends on the actual power (depends on the model). 13 Pro is physically capable of issuing 92 DB, but programmatically limited to 83 dB.
  • 🎧 Headphones: standard limitation EU Volume Limit – up to 85 dB, even if the headphones support a higher level.
  • 📱 Bluetooth devices: limitations vary by profile (e.g, A2DP It may have a lower limit than HFP call-in).

Interestingly, in some markets (like India or China), the restrictions are milder than in European firmware, which is due to local security regulations, and if your smartphone is bought in Europe, the chances of success are higher – the manufacturer leaves a “hidden margin” of volume.

⚠️ Warning: Exceeding 85 dB for more than 8 hours a day can lead to irreversible hearing loss (WHO data).If you remove restrictions, use Safe Sound in settings or limit listening time.

Method 1: Disable the restriction via MIUI settings (no root rights)

The easiest and safest method is to use the built-in MIUI options.It is suitable for most models, including the Redmi Note 12, POCO X5, Xiaomi 13T and other devices on the MIUI 12-15.

Instructions:

  1. Open the Settings. → Sound and vibration.
  2. Go to Additional Settings → Security and warnings.
  3. Find the Headphone Volume Limit (or EU Volume Limit) and turn it off.
  4. For speakers: return to Sound and vibration → Press the volume of the media and move the slider to the right (⋮) → Reset restrictions (if option is available).

Some firmware has the option hidden, so you can unlock it.

Activate Developer Mode (7 times press "Version" MIUI" on the telephone")

Enable debugging over USB in "Settings for developers"

Connect the phone to the PC and confirm the debugging permission

Install Activity Launcher from Google Play

-->

If the standard method didn’t work, try an alternative path through Activity Launcher:

  1. Open Activity Launcher and search com.android.settings.
  2. Select.Settings$SoundSettingsActivity.
  3. In the menu that opens, find hidden audio settings (can be called Advanced Sound or Engineering Mode).

⚠️ Attention: HyperOS firmware (2026) may have different paths to settings. If the sound becomes hoarse or distorted after the restrictions are turned off, return the settings back - this is a sign of overloading the speakers.

Method 2: Engineering Mode – Hidden sound settings

The Engineering Menu is a service tool that allows you to change hardware settings that are not available in the standard interface. There are two ways for Xiaomi to get there: through the kit code or using the MTK Engineering Mode app (for devices on MediaTek processors).

For smartphones on Qualcomm Snapdragon (most flagships Xiaomi):

  1. Open the Phone app.
  2. Enter the code ##36446337##
  3. Select Hardware Testing → Audio → LoudSpeaker Mode.
  4. In the Max Vol section, set the value 160 (usually 128-140 by default).
  5. Save the settings and restart the phone.

For devices on MediaTek (e.g. Redmi 10C, POCO M5):

  • 📱 Install the app MTK Engineering Mode.
  • 🔧 Go to Hardware Testing → Audio → Normal Mode.
  • 🔊 Change the Max Vol settings for Speaker and Headset to 150-160.
  • ⚠️ Do not change other settings (such as Type or Level) – this can cause sound loss.

After the changes, check the sound on different tracks. If there are wheezing or crackling, reduce the value of the Max Vol by 5-10 units. The optimal value is selected experimentally - for Xiaomi 12T it can be 150, and for Redmi Note 11 - 145.

Method 3: Modify system files (root or Magisk required)

If previous methods have not worked, you can go further and edit the system files responsible for limiting volume, which is suitable for advanced users, as it requires root access or a Magisk module.

You'll need:

  • 📱 Smartphone with unlocked bootloader and installed Magisk.
  • 💻 PC with installation ADB and Fastboot.
  • 📝 Backup of the file mixer_paths.xml (situated /vendor/etc/).

Step-by-step:

  1. Connect your phone to your PC and open the ADB terminal.
  2. Copy the original file on PC: adb pull /vendor/etc/mixer_paths.xml
  3. Open the file in a text editor (e.g. Notepad++) and find the lines: <path name="speaker"> <ctl name="RX1 Digital Volume" value="84" /> Change value="84" to value="92" (maximum - 96, but it's risky!).
  4. Save the file and return it back: adb push mixer_paths.xml /vendor/etc/ adb shell chmod 644 /vendor/etc/mixer_paths.xml
  5. Reboot the phone.

For HyperOS devices, the path to the file may be different: /vendor/etc/audio_platform_info.xml or /odm/etc/audio_policy_configuration.xml. To find the right file, use the command:

adb shell find / -name "audio.xml" 2>/dev/null

⚠️ Attention: Incorrect editing mixer_paths.xml It can cause complete loss of sound or looping of the boot.Be sure to back up through the backup before making changes. TWRP Or OrangeFox! What do you do if you lose the sound after you change the file: 1. Return the original file back through ADB. 2. If the phone doesn’t load, run the stock firmware through Fastboot. 3. To restore sound to 90% In some cases, the reset via fastboot erase userdata (but deletes all data!) 4: If you don't want to manually edit system files, you can use ready-made modules for Magisk. They automatically apply the optimal settings for your model.

Android 10+ (Magisk demands 26+) GitHub Installation of modules: Download the module file (.zip). Open Magisk → Modules. → Install it from storage. Select the downloaded file and wait for the installation. Reboot the phone. ViPER4Android After installation, you need to: Open the application and provide root access. Enable Master Limiter and install Output Gain on the +3.0 dB. Activate. FIR Equalizer to reduce distortions. 💡If the sound becomes robot-like after installing the module, disable the Force option. 48kHz output in settings ViPER4Android. Method 5: The most radical method is to install a custom core (e.g., FrancoKernel or Perseus) that optimizes the sound subsystem, which not only increases the volume, but also improves the sound quality by improving the sound quality: 🎛️ Optimized drivers ALSA. 🔊 Support for high-impedance headphones (300 Om.+). 🛠️ Fix distortion bugs at high volume. Installation process: Unlock the bootloader through the Mi Unlock Tool (Mi Account binding is required!). Install custom recovery (TWRP Download the kernel for your model (e.g. Perseus for the POCO F3). Sweat the core through recovery and clean up Dalvik/Cache. Advantages of custom kernels: ✅ The volume increases by 20-30% distortionless. ✅ Support LDAC aptX HD Bluetooth headphone. ✅ Improved energy consumption when playing music. ⚠️ Attention: Custom core installation resets Widevine L1 (Netflix will not be working on Netflix. HD) Before you run the firmware, check the compatibility of the kernel with your version. MIUI/HyperOS! Risks and how to minimize Volume above factory limits is always associated with risks. Here are the most common problems and ways to avoid them: Problem Cause Wheezing/Distortion solution Exceeding speaker power Reduce Max Vol in the engineering menu on the 5-10 Units Overheating Processor Increased load on sound chip Use optimised modules (e.g. JamesDSP) Fast battery discharge Increased power consumption of amplifier Disable volume gain at low charge (<20%) Sound loss after update Resets custom settings Create backup /vendor/etc/ Before updating To check if you are damaging the speakers, use the test: Turn on a track with a pure sine wave signal (for example, 1 KHz tone test. Turn the volume to maximum. If the sound is clear (no wheezing) - the speakers are safe. If there are distortions, turn down the volume. 💡Optimal volume boost is +3 dB for speakers and +6 dB for headphones. Exceeding these values significantly increases the risk of hardware damage. FAQ: Frequent questions on volume increase on Xiaomi Can the volume limit be removed without root? Yes, but the options will be limited. EU Volume Limit in settings (method) 1). Use the Engineering Menu (Method) 2) — work 60% Install booster apps (like Volume Booster), but they have minimal effect. Root is mandatory to maximize volume. Why, after the upgrade MIUI Sound is quiet again? Is the firmware update resetting user settings in mixer_paths.xml To avoid this, make a backup copy of the file before updating. /vendor/etc/mixer_paths.xml. After updating, return the file back through ADB or a root explorer. Use Magisk modules (e.g. Audio Modification Library) that automatically apply settings after updates. Is it safe to use ViPER4Android on HyperOS? Yes, but with the caveats: HyperOS (Android 14) requires Magisk 26.3+ and ViPER4Android FX Compatibility Patch module. Some features (e.g. Convolver) may not work - only use Master Limiter and Equalizer. When you see a sound stutter, turn off Force 48kHz in the settings. How to return the standard volume if the phone gets worse, if the sound module is overloaded or the following steps: For manual edits: return the original file mixer_paths.xml through ADB: adb push mixer_paths_original.xml /vendor/etc/ adb shell chmod 644 /vendor/etc/mixer_paths.xml If the sound doesn't recover, reset it through fastboot erase cache. In extreme cases, run the stock firmware through the Mi Flash Tool. POCO Yes, all of the methods described here are applicable to devices. POCO And Redmi, because they work on the same firmware. MIUI/HyperOS. Exceptions: POCO F1 and old models (up to) 2019 years) may not support the engineering menu through the code - use MTK Engineering Mode. on Redmi with MediaTek processor (e.g. Redmi) 9A) The path to sound settings may be different: /odm/etc/audio_platform_info.xml.
