How to strengthen the speaker on the Xiaomi phone: from system settings to hidden features

The weak sound of Xiaomi speakers is one of the most common complaints of the brand’s users. Even flagship models like the Xiaomi 14 Ultra or Redmi Note 13 Pro+ sometimes give a quiet sound compared to competitors. The reasons are due to the limitations of the MIUI firmware, hardware features or incorrect settings. But the good news is that you can turn up the volume on Xiaomi without root rights and the risk of damaging the device.

In this article, we will discuss 7 working methods, from basic settings to hidden functions of the engineering menu, learn how to safely raise the volume of media, calls and alarms without sacrificing sound quality, and find out why after updating MIUI speakers can become quieter, and how to fix it. All instructions tested on current models Xiaomi, Redmi and POCO (2022-2026).

1. Check basic sound settings in MIUI

Before digging deeper, make sure the problem isn't the trivial settings. MIUI often resets audio settings after updates or profile changes.

• 🔊 Multimedia Volume: Press the physical volume button and make sure the slider is at maximum. MIUI 14+ A separate media regulator has emerged - it's easy to miss.
• 🎵 Equator: Go to Settings → Sound and vibration → Sound quality → Equalizer. Choose the preset Bass or Rock, which automatically raises the volume of low and medium frequencies.
• 🔔 Do Not Disturb Mode: If activated, the sound of calls and notifications may become muted. → Notifications → Don't disturb.
• 📱 Sound Profile: Some firmwares have separate profiles for headphones and speakers. Make sure you choose Dynamic instead of Headphones".

If the sound is still quiet after this manipulation, move on to the next step: on Xiaomi 12T models and the newer MIUI, there is an additional audio amplifier hidden in the activation section of the engineering menu.

⚠️ Note: On certain devices (e.g, POCO F5) When you connect Bluetooth devices, the main speaker automatically mutes. Turn off Bluetooth to check the real volume.

2. Use of hidden codes for the diagnosis of speakers

Before you amplify the sound, you need to make sure the speakers are working correctly. Xiaomi has hidden test modes that help you identify hardware problems.

1. Open the Phone app and enter the combination: ##4636## Select Phone Information → Sound Testing.
2. To check the speaker for calls, type ##0673## or ##0289## (works on Redmi Note 11/12 and later).
3. For the multimedia dynamics test, use ##36446337## (some models may not work).

If the speaker sounds loud in the test and quiet in normal mode, the problem is exactly the MIUI settings or firmware. If the sound in the test is also quiet, it may be clogged or damaged (cleaning is described in section 6).

3. Activation of the hidden sound amplifier through the engineering menu

Xiaomi’s firmware has a hidden engineering menu (MTK Engineer Mode or Qualcomm Diag) where you can manually turn up the volume, a method that works on most models, but requires caution – incorrect settings can lead to distortion of the sound.

Instructions for Qualcomm processors (Xiaomi 13/14, Redmi Note 12/13, POCO F4/F5):

1. Install the MT Engineering Mode app (for MediaTek) or Qualcomm Engineer Mode.
2. Open the app and go to Hardware Testing → Audio.
3. Select LoudSpeaker Mode (or Speaker for Speaker).
4. In the Max Vol field, increase the value from 84 to 90-95 (don't put 100 - there will be wheezing!). For Min Vol, leave 0.
5. Press Set and restart the phone.

For MediaTek processors (Redmi 10A, POCO M4 Pro):

• In the engineering menu, select Hardware Testing → Audio → Speaker.
• Find Speaker Gain or Volume options and increase the values by 5-10 dB (maximum +15 dB).
• Save the settings and check the sound.

⚠️ Note: On models with stereo speakers (Xiaomi) 11T, Redmi K50) You'll have to tune each speaker separately. Don't turn up the volume more than a few times. +12 dB – This can damage the membrane.

4.Apps to amplify sound without root

If the engineering menu seems complicated, you can use third-party apps, which don't give you the volume boost that manual settings do, but they're safe and easy to use.-3 tested:

How to use:

1. Install the app and give access to the sound settings.
2. Turn on the option "Volume Amplifier" or "Max Volume".
3. Adjust the equalizer sliders: raise 100–500 Hz for bass and 1–5 kHz for medium frequencies.
4. Activate Loudness mode (if any) – it automatically equalizes the volume.

The downsides of this approach are that apps consume an extra battery and can distort at maximum volume, and for constant use, it is better to combine them with the settings of the engineering menu.

💡

If after installing the amplifier the sound became hoarse, reduce the level of bass in the equalizer and turn off the option "3D-sound (if any).

5. Update firmware and reset sound settings

Often, a quiet sound appears after the MIUI update.The fact is that new firmware versions can reset the user's equalizer settings or limit volume due to European regulations (for example, EN 50332 for hearing protection).

Step 1. Check out the MIUI version:

• Go to Settings → About Phone → MIUI version.
• If the version is older than 14.0.5, update via Settings → System Update.

Step 2. Reset the sound settings:

1. Open Settings → Applications → Application Management.
2. Find Music (or MIUI Music Player) and click Storage → Clear Data.
3. Do the same for the Settings app (this will reset the user's equalizer presets).

Step 3: Reinstall audio drivers (for advanced drivers):

If the problem persists, you can manually reinstall the audio modules via ADB:

adb shell pm uninstall -k --user 0 com.miui.player


adb shell pm install-existing com.miui.player

This command will reset the audio system to factory settings without losing data.

⚠️ Note: On Xiaomi models for the European market (designation) EEA The volume is artificially limited, and if your phone is bought in the EU, the only way to remove the restriction is to flash the global version. MIUI (But it voids the guarantee).

6. Cleaning speakers and checking hardware problems

If all the software methods didn't work, the problem could be physical. Xiaomi speakers are often clogged with dust or damaged when crashed. Here's how to diagnose and fix hardware malfunctions:

Signs of a clogged speaker:

• 🔇 The sound gets quieter over time.
• 🎵 Wheezing at high volume appears.
• 🕳️ You can see dust particles in the dynamics grid.

How to clean the speaker:

1. Dry cleaning: Use a soft brush (for example, for makeup) or compressed air (a canister for cleaning equipment).Do not use toothpicks or needles - they can damage the membrane.
2. Wet cleaning: Moisten the cotton swab in alcohol (no more than 70%) and gently wipe the speaker grille. Don't press hard!
3. Pull: Turn on the phone at maximum volume and bring the vacuum cleaner to the speaker at minimum power (distance 5-10 cm), Vibration will help to dislodge dust.

Damage check:

• 🔧 If the sound is gone after the fall, the speaker plume may have gone, and then you need to disassemble the device.
• 🔊 If the speaker wheezes even at minimum volume, most likely, the membrane is torn - a replacement is required.
• 📱 On models with stereo sound (Xiaomi) 11T Pro, Redmi K60) Check both speakers separately - often only one fails.

7. Alternative methods: headphones, Bluetooth speakers and MIUI-chips

If you can't amplify the built-in speaker, you can go the other way. Here are some alternatives:

• 🎧 Use high-impedance headphones (32 ohms and above) like the Xiaomi Hybrid Pro or 1MORE Triple Driver gives louder and cleaner sound than phone speakers.
• 🔊 Connect the Bluetooth speaker. Even the Xiaomi Mi Portable Speaker sound louder and better than the built-in speakers.
• 📱 Activate the Mode "Cinema" in Settings → Display. → Movie mode. It automatically amplifies the sound when you watch a video.
• 🔄 Turn on "Adaptive Sound" (available on the MIUI 14+). This feature analyzes ambient noise and adjusts the volume: Settings → Special facilities → Adaptive sound.

For owners of Xiaomi 13/14 or Redmi Note 12 Pro+, there is another feature: dual speakers with support for Dolby Atmos.

1. Install Dolby Atmos from Google Play.
2. Select the "Cinema" or "Music" profile.
3. Turn on the "Dynamic Sound" option, and it will add volume.

💡

On models with an infrared port (Redmi Note 11 and older), you can connect external speakers via an IR transmitter, which will give a louder sound without loss of quality.
