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

Why Xiaomi speakers are quietly playing and what to do about it

Have you noticed that your Xiaomi is quieter than before? Or is it weaker than your friends on similar models? There are a number of reasons, from the banal clogging of the speaker to the software limitations of the manufacturer. In 80% of cases, the problem can be solved without repair, whether it is enough to set up the system correctly or clean the hardware components.

It’s important to understand that low volume doesn’t always mean breakage. For example, Redmi Note models often have a more restrained sound compared to Xiaomi 13 flagships due to different acoustic modules. And some firmware (especially global versions) artificially lower the maximum volume values to meet European safety standards.

In this article, we'll go through all the working methods, from the elementary to the advanced, including the hidden settings of the engineering menu, but remember: some methods can cause sound distortion or overheating of the speaker with prolonged use at maximum. Start with the safest options.

1. Basic volume settings in MIUI

Before you dig deeper, check the obvious. MIUI has separate regulators for different types of sound, and often users just don't notice that one is twisted to a minimum.

Open Settings → Sound and vibration and pay attention to:

• 🔊 Multimedia Volume – Responsible for Music, Video, Games
• 📞 Call volume – separately regulates incoming calls
• 🔔 Loudness of notifications – often forget to check
• 🎧 Headphone volume – can affect sound when connecting Bluetooth devices

Also on this menu is a Dynamic Range slider (on some models) if it's on, the system automatically lowers the volume in quiet music/film snippets - turn it off for a uniform sound.

💡

On models POCO and Redmi with IR-Check if the "Silent Sound When Using the Remote" mode is activated on the port, and this function automatically mutes the speakers when you control the equipment through the IR port.

Cleaning of speakers from dust and debris

One of the most common physical causes of silent sound is clogging of the speaker, and dust, villi, or even small food particles (if the phone is often on the table) can block the membrane, reducing the volume by 30-50%.

How to clean the Xiaomi speaker indiscriminately:

1. Take a soft toothbrush (new or clean) with a short pile.
2. Carefully, without pressure, walk along the speaker grid in circular motions.
3. Use a compressed air spray (to clean keyboards) -- blow out the dust with short presses. Hold the balloon vertically to keep the liquid out!
4. To remove sticky contaminants, moisten the cotton swab in isopropyl alcohol (70%+) and gently wipe the grille.

⚠️ Warning: Never use sharp objects (needles, toothpicks) - they can damage the membrane. Also avoid wet wipes: moisture trapped inside will lead to corrosion of contacts.

3.Use of engineering menu to increase volume

Engineering Mode is a hidden settings section where you can manually increase the power of the sound, which works on most Xiaomi models, but requires caution: incorrect values can lead to distortion of the sound.

Instructions for entry:

1. Open the Phone app and enter the combination: ##36446337###
2. Select Hardware Testing → Audio → LoudSpeaker Mode.
3. In the Max Vol section, you will see the current volume limits (e.g., Level 0: 140).
4. Increase your values by 10-20 units (for example, from 140 to 160). Do not bet more than 180 - this is fraught with distortion!
5. Save the settings and restart the phone.

For models with MIUI 12+, the path may be different: Hardware Testing → Audio → Normal Mode → Speaker → Max Vol.

Record the current volume values|Do not increase the value by more than 20%|Check the sound after each change.|Reboot your phone after settings-->

⚠️ Note: Some firmwares reset the engineering menu after the system update. Also, after increasing the volume, check the sound at different frequencies - wheezing on high notes means that the value is too high.

4. Apps to amplify sound: top-5 tested utilities

If you don't want to go through the settings, you can use third-party apps, and they work in different ways, some just turn up the volume programmatically, others optimize the sound through the equalizer.

The best apps for Xiaomi in 2026:

• 🎛️ ViPER4Android — It's an advanced sound processor with equalizer and amplifier, requires root or Magisk for full functionality, but even without it, it gives you a noticeable increase in volume.
• 🔊 Volume Booster GOODEV — A simple booster with pre-profiles for music, videos and calls.
• 🎵 Equalizer FX — built-in MIUI It's an equalizer, but with advanced settings, and it allows you to raise the low and high frequencies, which subjectively makes the sound louder.
• 📱 Precise Volume, which allows you to access the "hidden" volume levels between standard divisions, and is useful for fine-tuning.
• 🔇 SoundAssistant (from Samsung, but runs on Xiaomi) – allows you to split volume control for each application.

How to install ViPER4Android on Xiaomi without root:

1. Download APK from the official website (viperatmos.com).
2. Install the ViPER4Android FX app and driver.
3. In the audio settings, select ViPER4Android as the audio handler.
4. Activate Extreme profile and increase Master Gain by 3-5 dB.

💡

Boost applications increase the load on the processor and can drain the battery faster on the processor. 10-15%. Turn them off when you are not listening to music.

5. Hardware causes of silent sound and their elimination

If the software methods didn't work, the problem could be hardware, and here are the most common hardware causes and ways to diagnose them:

Testing the speaker for physical damage:

• 🔍 Visual examination - flash a flashlight on the speaker grille. Can you see the damage to the membrane (breaks, dents)?
• 🎧 The headphone test, plug in the headphones, and if the sound is loud and the dynamics are quiet, the hardware is a problem.
• 🔄 Restart in Safe Mode – If the sound normalizes, the third-party app is to blame.
• 📱 Compare it to another device, play the same track on another phone. If the difference is significant, your speaker is faulty.

Typical hardware faults:

⚠️ Note: If your Xiaomi has fallen into water or been hit hard, don’t try to disassemble it yourself to repair the speaker. In such cases, other components (such as a microphone or accelerometer) are often damaged, and a comprehensive diagnosis is required.

6. Alternative methods: from Bluetooth speakers to custom firmware

If none of the above has worked, consider radical or alternative methods.

Connection of external devices:

• 🎧 Bluetooth speakers or headphones are the easiest way to get loud sound.Modern Xiaomi models support the aptX Adaptive codec, which provides high quality transmission.
• 🔌 USB-C audio adapter – if the 3.5 mm connector is missing, an adapter with an external DAC (for example, Xiaomi) USB-C to 3.5mm) It will give a clearer and louder sound.
• 📦 Portable amplifiers – devices like FiiO A1 connect to headphones and amplify the signal without loss of quality.

Software solutions for advanced users:

• 🛠️ Custom firmware – for example, Pixel Experience or LineageOS often have less stringent volume limits than stock firmware. MIUI.
• 🔧 Magisk modules – Audio Modification Library module allows you to fine-tune the sound, including removing restrictions.
• 📱 ADB-commands – a computer can send a command to reset the sound settings: adb shell settings put global volume_steps 30 (Increases the number of volume control steps).

⚠️ Note: Installing custom firmware or using Magisk will result in a loss of warranty and may cause problems with banking applications (due to the SafetyNet trigger). → Additionally. → Backup and reset.

7.When to contact the service center

If you've tried all the ways, but the sound is still quiet, it's probably a bigger problem than it sounds.

• 🔇 The sound completely disappears after the phone overheats (may indicate the chip dump audio codec).
• 🔊 The speaker makes extraneous noises (crackling, squeaking) even when the music is turned off.
• 📉 Volume spontaneously changes during playback.
• 💧 The phone fell into the water or was subjected to severe vibration (for example, in a car without a mount).

The cost of repairing the speaker in Xiaomi varies:

• Replacement of the speaker — 800-2000₽ (model-wise).
• Replacement of the plume — 1000-2500₽.
• Mainboard repair (in case of damage to audio track) - from 3000₽.

Official Xiaomi service centers in Russia can be found on the website mi.com/ru/service/center. Check before you visit if the warranty period has expired (usually) 12 months from the date of purchase).

💡

If your Xiaomi is guaranteed, don’t open it yourself and install custom firmware. This will cancel the warranty and you will have to pay for the repair out of your pocket.
