How to increase the sound on the Xiaomi smartphone: from standard settings to hidden chips

Have you ever encountered a situation where on Xiaomi Redmi Note 12 or POCO X5 the sound in the speakers is barely discernible, even at maximum volume? or during the call of the interlocutor is not audible, despite the full volume scale? This problem is familiar to many owners of Xiaomi smartphones — especially after MIUI updates or when using budget models with weak speakers.

In this article, we’ll look at all the possible ways to increase sound on Xiaomi, from basic settings to hidden engineering menu features and third-party utilities. You’ll learn how to turn up the volume in speakers, headphones and during calls, and what to do if the sound disappears after firmware. Importantly, some methods require caution, so read the warnings carefully!

1. Basic volume settings in MIUI

Before you dig deeper, check the obvious. There are several places in MIUI where you can adjust the volume separately for different scenarios.

• 🔊 Fast Volume Menu: Press the Physical Volume button up/down → A slider will appear. Tap the gears on the right to divide the adjustment for Media, Calls, Alarms and Notifications.
• 🎵 Equator: Go to Settings → Sound and vibration → Equalizer. Choose Bass' preset or Rock, which can visually increase volume by amplifying low frequencies.
• 📞 Loudness of calls: in Settings → Sound and vibration → Volume of calls: Enable Volume Up (if available).

Note that on some models (such as Xiaomi 13T) there is a separate slider for System Sounds in the volume menu - it is also worth checking. If the sound is quieter after the MIUI update, try resetting the sound settings to factory: Settings → Sound and vibration → Resetting the sound settings.

2. Engineering menu: hidden volume settings

If standard methods don't work, it's time to check the Engineering Mode, where you can manually increase the maximum volume threshold for speakers and headphones. Attention: Incorrect settings can cause sound distortion or damage to speakers!

Instructions for entry:

1. Open the Phone app.
2. Enter the combination: ##36446337## (or #4636## on older versions of MIUI).
3. Choose Hardware Testing → Audio.

In the engineering menu, pay attention to the following parameters:

• 🔈 Speaker Mode: Normal Mode or Loud Speaker Mode.
• 🎧 Headset Mode: Select High Volume for headphones (if available).
• 📊 Max Vol: Here you can increase the maximum volume value (for example, from 150 to 160).

Record the current parameter values

Do not increase Max Vol by more than 10% of the standard

Check the sound after each change.

Do not save settings when distorting the sound-->

On some firmware (e.g. MIUI 14), the engineering menu may be blocked, in which case try an alternative method:

adb shell settings put global audio_safe_volume_state 0

This command disables the limit of safe volume in Android (ADB and USB debugging enabled are required).

3. Sound amplification applications

If you don't want to dig into the settings, you can use third-party utilities. They work in different ways: some amplify the sound programmatically, others adjust the equalizer, and others bypass the limitations of Android.

Top.-3 Proven applications for Xiaomi:

ViPER4Android is the most powerful solution, but installing it requires root rights or a Magisk module. If you are not ready for this, choose Volume Booster or Equalizer FX. Importantly, after installing any booster, check the sound for distortion - if hoarseness occurs, reduce the amplification level.

💡

Before installing the sound booster, back up the sound settings in MIUI: Settings → Sound and Vibration → Backup the sound settings.

4.Sound problems after MIUI update

Many users complain that after upgrading to MIUI 14 or HyperOS, the sound has become quieter, due to Google's new restrictions on safe volume (EU Volume Limitation Directive).

• 🔄 Update rollback: if the sound disappeared immediately after the update, try rolling back to the previous version via Settings → The phone. → Updating the system → Three points. → Select a Service Package.
• 🛠️ Resetting sound settings: go to Settings → Annexes → Application management → Three points. → Reset the application settings, then select Sound Settings.
• 📱 Switching region: sometimes it helps to change the region to India or the United States (where the restrictions are milder). VPN when setting up the phone.

If the sound is gone (the speakers are not working), check:

1. Is not activated mode Do not disturb (Settings → Notifications → Do not disturb).
2. Is the system sounds turned off in Settings → Sound and vibration → Quiet mode?
3. Is the sound in safe mode (hold the power button → Safe Mode) If so, a problem in a third-party app.

5. Hardware problems: when software methods do not help

If you’ve tried all the ways, but the sound remains quiet or distorted, the problem may be in the hardware.

• 🔊 Contaminated speaker: Dust and pile block the sound holes, clean them with a soft brush or compressed air (do not use sharp objects!).
• 💧 Moisture: Even after drying, the oxidation of the contacts can make the sound worse.
• 🔌 Damaged plume speaker: common problem after falls. Symptoms: sound appears and disappears when you press the body.
• 🎧 3.5mm faulty connector (on jack models): check the headphones on another device. If they work, the problem is the smartphone connector.

To diagnose hardware problems:

1. Connect headphones – if the sound in them is normal, the problem is in the phone’s dynamics.
2. Call your phone from another device – if the person can’t hear you, the microphone is faulty.
3. Record a voice note – if the recording is silent, the problem is with the microphone or noise cancellation.

💡

If the sound is only lost in specific applications (for example, in TikTok or YouTube), the problem is not in the phone, but in the settings of the application itself or its cache. → Annexes.

6. Specific solutions for different Xiaomi models

Some Xiaomi models have unique sound problems, and here are the solutions for the most popular lines:

For Xiaomi 13 Ultra and other flagships with Harman Kardon speakers: If the sound is quieter after the update, check the Dolby Atmos settings. Sometimes resetting this module (Settings → Apps → Dolby → Storage → Clear Data) returns normal volume.

7. Alternative methods: from Bluetooth to Magisk

If the standard methods didn’t work, try these non-obvious solutions:

• 📶 Bluetooth amplifiers: connect your phone to an external Bluetooth amplifier (like Anker Soundcore Boost). A1, POCO C40).
• 🔧 Magisk modules: For rooted devices, there are modules like the Audio Modification Library or JamesDSP that allow you to fine-tune the sound.
• 🎛️ ADB-Disable Android Limits: Adb shell settings put global volume_steps 30 adb shell settings put global audio_safe_volume_state 0 The first command increases the number of volume steps, the second - turns off safe mode.
• 🔄 Firmware change: Some models (like the Redmi Note 8 Pro) have louder sound on custom firmware like Pixel Experience or LineageOS.

Critical: Using ADB and Magisk can violate warranty and lead to unstable phone performance.Before experimenting, back up via Settings → Additional → Backup and Reset.

FAQ: Frequent questions about Xiaomi sound

⚠️ Warning: Volume increases above factory settings can cause speaker damage or loss of warranty.On stereo models (Xiaomi 12 Pro, POCO F4) risk is higher – uneven load can disable one of the speakers.

⚠️ Attention: If you are using ViPER4Android or other sound modifiers, before contacting the service center, be sure to delete them and reset the sound settings. Otherwise, you may be denied warranty repairs, citing "unauthorized software changes".
