How to increase the volume of the speaker on Xiaomi: from standard settings to hidden features

Are you missing important calls because Xiaomi's speaker is too quiet? Or is the music in your headphones sounding like a bucket? The problem of low volume is familiar to many smartphone owners of this brand — especially on budget models like the Redmi 9A or Poco M3, where the manufacturer has saved on audio chips. But don't be quick to blame the iron: in 80% of cases, you can increase the volume programmatically without disassembling the phone.

In this article, we’ll look at 7 working volume-boosting techniques on Xiaomi, from basic settings to hidden engineering menus and third-party utilities. We’ll look at which methods are safe for speakers and which can shorten their lifespan. You’ll also learn why the MIUI update has made the sound quieter and how to fix it. All instructions are relevant for MIUI 12-14 firmware and models from Redmi Note 10 to Xiaomi 14 Ultra.

1. Check the basic sound settings

Before digging into the engineering menu, make sure the problem isn't the trivial settings. There are a few places on Xiaomi where you can accidentally turn down the volume:

• 🔊 Volume Control: Press the physical volume button and check if the slider is at a minimum. on some models (e.g. Xiaomi) 13T) There are separate regulators for media, calls and alarms.
• 🎵 Sound Profile: Go to Settings → Sound and vibration → Sound modes. Make sure you don't pick Quiet or No Sound».
• 📱 Inactive speakers: on smartphones with stereo sound (for example, Xiaomi 12 Pro) check whether one of the speakers is turned off in Settings → Special facilities → Audio balance.

If the sound is still quiet after this manipulation, move on to the next step: on models with MIUI 14, the "Amptimize Sound" setting may be reset after the update - it must be turned on manually (more on this below).

2. Enable sound amplification in the MIUI settings

Xiaomi hides the useful feature "Amptimize Sound" in the depths of the menu. It increases volume by 10-30% due to software processing, but can add distortion at maximum volume.

1. Open the Settings. → Sound and vibration.
2. Slip on Additional sound settings (on some firmware, the item is called Sound Quality).
3. Find the option of Sound Amplification or Volume Amplifier and activate it.
4. Reboot your phone to make the changes take effect.

On the Redmi Note 11 and later, this option may not be available in the standard settings, but it was moved to the MIUI lab.

• 🔧 Enter the code ##6484 in the Phone app##.
• 🔍 In the laboratory search, enter “amplification” and turn on the appropriate switch.

Check the current version of MIUI in Settings → About the phone

Backup settings in Settings → Additional → Backup

The battery should be at least 30% charged.

3. Use the Engineering Menu (MTK/Qualcomm)

The engineering menu is the heart of audio settings, where you can manually increase the volume of speakers, microphones and even change the frequency characteristics.

Instructions for Qualcomm processors (most flagships Xiaomi) and MediaTek (budget Redmi) are different:

⚠️ Warning: If after changes in the engineering menu there is a wheezing or cracking, immediately reset the settings to the factory in Settings → Resetting settings → Reset network settings: Volume rises above 180-200 units on Qualcomm or 120 on MediaTek could physically damage speakers!

4.Install applications to amplify sound

If standard methods didn't work, try third-party utilities. They work on two principles: either amplify the sound programmatically (like an equalizer), or bypass the limitations of MIUI.

To install ViPER4Android on Xiaomi without root:

1. Download APK from the official website (version for MIUI).
2. Install Magisk Module for compatibility.
3. In the application settings, select the Legacy Mode driver.
4. Activate the ViPER DDC profile and set the amplifier to +3-5 dB.

💡

Before installing third-party equalizers, disable the built-in MIUI equalizer in Settings → Sound → Equalizer to avoid conflicts.

5. Update or roll back the firmware

A common cause of silent sound is firmware bugs, such as when upgrading to MIUI 14.0.5, many Xiaomi 12T users complained of a 40 percent decrease in loudness.

• 🔄 Reverse to old version: If the problem appears after the update, go back to the previous firmware via Settings → The phone. → Updating the system → Three points. → Select a Service Package.
• 📲 Manual installation of the patch: on forums 4PDA Frequently put fixes for audio bugs (see phone model) + «soft-sound»).
• 🛠️ Resetting: Sometimes resetting to factory through Settings helps → Additionally. → Resetting settings (does not delete files, but resets audio settings).

Before rolling back the firmware, check if the bootloader is locked on your model. On new Xiaomi (released after 2022), this requires unlocking through the Mi Unlock Tool, which will reset all data.

⚠️ Note: Firmware rollback on HyperOS models (e.g. Xiaomi 14) may lead to lockdown IMEI. Before the procedure, check the compatibility of versions on the site. MIUI Downloads.

6. Check for hardware problems

If the software methods did not help, the cause may be a physical malfunction:

• 🔇 Pollution speaker: dust and pile block the membrane. Clean the speaker hole with a soft brush or compressed air (do not use needles!).
• 💧 Moisture: Even after drying, oxidized contacts can turn down the volume, and only a change in speaker will help.
• 🔌 Train problems: on Xiaomi with a detachable case (for example, Redmi Note 8 Pro), the speaker plume can move away.

To diagnose a hardware problem:

1. Connect headphones – if they sound normal, the problem is the phone’s dynamics.
2. Call your phone from another device and listen to the sound of the call from the side.
3. Record the voice message and check if your voice is distorted when playing.

💡

If the quiet sound only appears in specific applications (like YouTube or WhatsApp), the problem is not with the dynamics, but with the settings of those programs. Check the permissions to access the microphone and speakers in Settings → Apps → Permissions.

7. Alternative solutions for specific models

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

For Xiaomi Mi. A2/A3 (On pure Android, there are other rules: these models do not have an engineering menu Xiaomi, but support ADB-commands to change the volume, such as to increase the volume of the media to maximum:

adb shell settings put system media_volume_steps 30

Once you have completed the command, restart your phone. On Android One models (like the Mi A3), this method works more stable than the engineering menu, but requires a PC connection.
