How to maximize the sound on the Xiaomi phone: from settings to engineering menu

The weak sound on Xiaomi’s smartphone is one of the most common problems faced by the brand’s users. Even flagship models like the Xiaomi 14 Ultra or the POCO F6 Pro sometimes produce a quiet sound in speakers, headphones or during a conversation, the reasons may lie in software restrictions, pollution of speakers, incorrect settings or even hardware malfunctions, but in 90% of cases the problem can be solved without going to the service center.

In this article, we’ll look at all the possible ways to amplify sound, from basic MIUI settings to hidden engineering menu features and third-party apps. You’ll learn how to turn up the volume without losing quality, why sound can disappear in certain applications (for example, YouTube or Telegram), and what to do if the speakers suddenly become quieter after updating the firmware.

Important: All instructions are checked on current versions of MIUI 14/15 (including global and Chinese builds) and are suitable for most models - from the budget Redmi Note 12 to the premium Xiaomi MIX Fold 3. If your phone is released before 2019, some items may be missing.

1. Basic volume settings in MIUI

Before you dig deeper, check out the obvious. MIUI has several levels of sound regulation that many users miss:

• 🔊 Volume Controllers: Press the physical volume button → You'll see a slider panel for Media, Alarm, Call and Notifications, and make sure they're all set to maximum.
• 🎵 Individual Application Customization: Go to Settings → Sound and vibration → App volume: You can turn up the volume for specific programs (e.g., make Spotify louder than YouTube).
• 📞 Voice amplification during a call: In the same section, activate the option “Improving voice” – this will increase the volume of the interlocutor by suppressing noise.

If the sound is still quiet after this manipulation, the problem may lie in the limitations of MIUI, because Xiaomi artificially lowers the maximum volume on some models (especially in the EU versions) due to European safety standards, bypassing this through the engineering menu or third-party utilities - more on this.

⚠️ Note: On Xiaomi models with stereo speakers (e.g. Redmi) K70 pro POCO X6 Pro) check if one of the speakers is silenced. To do this, turn on the music and alternately close the upper and lower speaker with your finger - if the sound is completely lost, then only one speaker works.

2. Engineering menu: hidden sound settings

The Engineering Mode is a hidden MIUI section where you can fine-tune your sound settings, including amplifying the volume above standard limits. Careful: improper changes can cause sound distortion or damage to the speakers.

To get into the engineering menu:

1. Open the Phone app.
2. Enter the code ##36446337##
3. Choose Hardware Testing → Audio.

In the Audio section, pay attention to the following parameters:

• 🔧 Headset Mode – Volume setting for headphones (values) 0-160, standard-maximum — 100).
• 🔊 Speaker Mode – speaker volume (you can increase to 150, but you risk distortion).
• 🎤 Mic Gain - microphone amplification (useful if the interlocutor does not hear you well).

After the changes, restart your phone. If the sound gets worse (wheezing, crackling), return the values to the standard.

3. Sound amplification applications

If the standard methods don't work, third-party utilities will come to the rescue. 15 Apps and selected top-3, That really works for Xiaomi:

1. Volume Booster GOODEV (🌟 Best choice: The app increases volume by changing system settings, supports separate settings for speakers, headphones and Bluetooth devices.
2. SoundAssistant (from Samsung, but it works for Xiaomi) allows you to adjust the balance between the left / right speaker, amplify the sound in the headphones and even create customized profiles for different scenarios (games, music, calls).
3. Equalizer FX (for bass lovers) Not so much increases the volume as improves the sound due to the equalizer, useful if your Xiaomi has weak low frequencies (for example, on the Redmi 10C).

Warning: Some applications (such as Volume Booster) require ROOT-without them, the effect will be minimal. MIUI settings may reset.

4. Cleaning of speakers and connectors

Often, the cause of quiet sound is trivial – contamination of speakers or headphone jacks. Dust, pile from your pocket or even sweat can block sound waves, reducing the volume by 30-50%, especially for models with a lower speaker (for example, the POCO X5 Pro or Redmi Note 13).

How to clean:

• 🧹 Dry cleaning: Take a soft toothbrush (or makeup brush) and walk gently through the speaker grille. Don't press hard!
• 💨 Compressed air: A compressed air canister (sold in electronics stores) will help blow out dust from hard-to-reach places. Keep the balloon vertically so as not to freeze the speaker.
• 🔌 Headphone jack: If the sound is quiet only in the headphones, the problem may be the connector. Clean it with a toothpick (wound with cotton wool soaked in alcohol).

For models with IP53/IP68 (such as Xiaomi 13T Pro), avoid liquids – despite protection, moisture entering the speaker can worsen the sound. If the volume does not return after cleaning, it may be mechanically damaged (for example, after a fall).

5. Adjusting the sound through ADB (for advanced)

If you're ready to dive into technical details, ADB (Android Debug Bridge) allows you to change system sound settings that are not available through normal settings. This method works without ROOT, but requires a computer and basic command-line knowledge.

Instructions:

1. Turn on USB Debugging on your phone: Settings → About Phone → MIUI version (click 7 times to activate Developer Mode), then go back to Settings → Additional → Developers → Debugging on USB.
2. Connect your phone to your PC and execute the command: adb shell settings put global volume_steps 30 This will increase the number of volume control steps from standard 15 before 30, This will allow you to adjust the sound more accurately.
3. To increase the volume, use: adb shell settings put global volume_music_speaker_scale 1.5 Here. 1.5 — The gain factor (can be set from the 1.1 before 2.0, higher 1.7 risk).

Once you've applied the commands, restart your phone. To get it back, use the same 1.0 commands.

⚠️ Attention: Some teams ADB They may conflict with updates MIUI. After a major update (for example, with the MIUI 14 on MIUI 15) the settings will reset and they will have to be reused.

💡

If the ADB commands have distorted the sound, try lowering the coefficient to 1.3 and restarting the phone, and check if the Adaptive Sound mode is enabled in the audio settings, which can automatically turn down the volume.

6.Sound problems after MIUI update

Many users complain that the sound has become quieter since the firmware update, which is due to Xiaomi making changes to the sound stack (especially in global versions of MIUI to meet European standards).

• 🔄 Update rollback: If the problem appears after the update, try to roll back to the previous version via Fastboot. XDA Developers (Search for your phone model).
• 🔊 Resetting sound settings: Go to Settings → Annexes → Application management → Three points. → Reset the settings. Select the sound settings.
• 📱 Custom core installation: For advanced users, cores like FrancoKernel or Kirisakura often improve sound but require an unlocked bootloader.

If the silent sound only appears in specific apps (like WhatsApp or TikTok), try:

1. Clear the app cache: Settings → Apps → [App name] → Clear the cache.
2. Disable energy saving for the application: Settings → Battery → Energy saving → Select applications.
3. Reinstall the app.

On some models (for example, Redmi Note 11 Pro+) helps to disable the function Mi Sound Enhancer in the audio settings – it sometimes conflicts with updates.

7. Hardware malfunctions: when it's time to go to service

If none of the software methods worked, the problem could be hardware, and here are the signs that it's time to get your phone repaired:

• 🔇 The sound disappears completely in one of the speakers (the second one works normally).
• 🔊 There was a wheezing or cracking, even at a minimum volume.
• 📵 The phone does not recognize the headphones, although they are good.
• 💥 The sound became quiet after falling or getting moisture.

The cost of repairing a speaker on Xiaomi varies from 800 to 2500 rubles depending on the model. For flagships (for example, Xiaomi 13T) it is often more profitable to replace the entire dynamic module, rather than a separate speaker. In Xiaomi service centers, before repair, they must conduct a free diagnostic.

If the phone is warranty, do not open it yourself - this will void the warranty.

💡

Before visiting the service, make a data backup - when replacing the speaker or motherboard, you may need to reset the phone to factory settings.
