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

Have you ever caught yourself thinking that even at maximum volume, music or video on Xiaomi is difficult to hear in a noisy subway or on the street? The problem of low sound is relevant for many models of the brand – from the budget Redmi Note to the flagship Mi 13 and Mi TV. The reasons lie in both hardware limitations (small speakers, a weak amplifier) and software – the manufacturer specifically lowers the volume to protect speakers from overload.

In this article, we’ll look at 7 working ways to increase sound on Xiaomi devices, including hidden MIUI settings, engineering menus, and even hardware solutions. Importantly, not all methods are safe for speakers — some can distort or shorten the life of the hardware. We’ve flagged the risky options with special warnings.

Start with the simplest and safest ways, and then move on to advanced techniques for power users. If your Xiaomi model is released after 2020 (e.g. Redmi Note 12, POCO X5, Mi 11), most of the instructions will be relevant. For older devices (before MIUI 12), some points may differ — check in the comments.

1. Basic volume settings in MIUI

Before digging deep into system files, check the obvious settings. MIUI 14/15 has a few hidden options that many users skip.

Open Settings → Sound and vibration. Here, pay attention to:

• 🔊 Separate volume control: in new versions MIUI You can independently adjust the volume for media, calls and alarms, and check if the media slider is at a minimum while you increase the overall sound.
• 🎵 Mi Sound equalizer: turn it on and select Bassy preset+ or Loudness+ — add 10-15% volume by increasing low and medium frequencies.
• 📱 For the street mode: activates automatically at high noise level (you need to allow access to the microphone for the system). 20-30%, But it doesn't work on all models.

If you don’t have Mi Sound on your menu, upgrade to the latest version of the firmware or install it separately through the Mi App Store. Android 12+ devices also have a system equalizer available – it can be found in Settings → Additional → Special Features → Sound Settings.

⚠️ Note: On some devices (Redmi) 9A, POCO M3) When you activate the mode, background noise may appear on the street, and this is due to the noise reduction algorithm.

2. Increase volume through the engineering menu (MTK/Qualcomm)

The engineering menu is a hidden settings section where you can manually change audio settings, including maximum volume values, and only works on devices with MediaTek (MTK) or Qualcomm Snapdragon processors.

For MediaTek:

1. Open the Phone app and enter the combination: ##3646633##.
2. Go to the Hardware Testing → Audio section.
3. Select Normal Mode (for speakers) or Headset Mode (for headphones).
4. In the Max Vol field, change the value from 160 to 180-200 (no higher!).
5. Save the settings and restart the device.

For Qualcomm Snapdragon:

1. Enter the code ##8647## (some models may not work).
2. Select Audio → Speaker Gain.
3. Increase Media and Ring values by 5-10 units (maximum 255).

If the codes don't work, try an alternative method through the MTK Engineering Mode app (available on the Play Market).The sound will get louder after the changes, but hoarseness may appear at maximum volume - this is normal for most budget models.

3.Use of third-party applications to amplify sound

If the system settings don't work, third-party utilities come to the rescue, and we tested 5 popular apps and selected the most effective ones:

The easiest option is the Volume Booster GOODEV.

1. Launch the application and give access to the sound settings.
2. Move the Boost Media Volume slider by 20-30%.
3. Activate the Ignore Android Volume Limits option.

ViPER4Android requires an unlocked bootloader and Magisk installed. This app gives you the maximum volume gain, but it takes 15-20 minutes to set up. Ready presets can be downloaded on the 4PDA forum (look for themes for your Xiaomi model).

⚠️ Attention: Apps like ViPER4Android Can conflict with system sound drivers MIUI. If the sound is gone after installation, delete the app and restart the device. 10% of the time you need to reset the audio settings via Settings. → Annexes → Application management → ViPER4Android → Warehouse → Clear the data.

Modification of system files (for advanced users)

This method involves editing a file mixer_paths.xml, It's the one that controls volume limits on Android, and it requires root access and backup!

Instructions:

1. Install Root Explorer or FX File Explorer with superuser rights.
2. Cross the path: /system/vendor/etc/mixer_paths.xml (In some models, the path may be different: /system/etc/mixer_paths.xml).
3. Find the following lines: <path name="speaker"> <ctl name="RX1 Digital Volume" value="84" /> <ctl name="RX2 Digital Volume" value="84" />
4. Increase the value from 84 to 90-95 (not higher!).
5. Save the file, set the rights 644 (rw-r--r---).
6. Reset the device.

Qualcomm Snapdragon devices may need file editing mixer_paths_qrd_skuh.xml. On Xiaomi models with stereo speakers (for example, POCO F4 GT, Redmi K50 Gaming) edit the settings for both speaker-left and speaker-right channels.

Make a backup through TWRP

Check the processor model (MTK/Qualcomm)

5. Hardware methods of amplifying sound

If software methods fail, physical improvements are worth considering. Here are 3 proven options:

• 🔧 Replacement speaker: AliExpress sells enhanced speakers for popular Xiaomi models (for example, for Redmi Note). 10 pro POCO X3 NFC). Cost — 500-1500 Rubles, but require a soldering iron and experience disassembling phones.
• 🎧 External amplifier: Connected through USB-C Bluetooth amplifiers (for example, FiiO) BTR3K) It's up to 200 percent volume without distortion, and it's good for listening to music through headphones.
• 📦 Resonator case: Passive amplification cases (such as Spigen Style Ring) redirect sound waves forward, increasing the volume by a few seconds. 15-20%. Minus – works only in the horizontal position of the phone.

For Xiaomi Mi TV (including Mi TV 4S/5X), you can connect an external sound bar via HDMI ARC or optical output. Even budget soundbars (such as Xiaomi Mi Soundbar) give 3 times more powerful sound than the built-in TV speakers.

If you decide to replace the speaker yourself, consider:

• Xiaomi often uses speakers with non-standard connectors (for example, the Redmi Note 9 Pro has a 4-pin plume).
• After the replacement, you may need to calibrate through the engineering menu (#3646633# → Audio → Speaker Calibration).
• The warranty on the device will be cancelled.

6. Sound optimization for specific scenarios

Sometimes the problem is not the maximum volume, but the wrong settings for specific tasks.

For music:

• 🎶 Use Mi Music with Mi Sound Enhancer enabled (in player settings).
• In Spotify or YouTube Music, activate volume normalization (Settings → Play → Normalize Volume).
• For headphones, turn on Dolby Atmos in Settings → Sound and Vibration → Sound Effects.

For videos and movies:

• 🎬 V MX Player or VLC increase the amplification of the sound to +10 dB in audio settings.
• For Netflix and YouTube, turn off audio compression: on YouTube, select High Bitrate in the quality settings.
• On Mi TV, activate the Mode of the Cinema in the sound settings - it increases the dynamic range.

For calls and voice messages:

• 📞 B Settings → Special facilities → Sound settings turn on voice amplification.
• For WhatsApp and Telegram, set the maximum priority in the notification settings.
• If the interlocutor is not audible, try to switch to VoLTE (in the settings). SIM-map).

💡

If the sound in the YouTube video is too quiet, add the &vq=hd1080 (e.g.: youtube.com/watch?v=XXX&vq=hd1080) at the end of the link, which will force the audio track to be of high quality if available.

7. Diagnostics of sound problems

If the sound is still quiet despite all the manipulations, it may be a hardware malfunction.

1. Speaker check: - Call the phone and turn on speaker. If the sound is quiet only in this mode - the problem is in the main dynamics. - Connect the headphones: if the sound is normal, the speaker or amplifier is to blame.
2. Microphone test: - Record a voice message on Telegram. If the recording is quiet, clean the microphone of dust (use a toothpick or compressed air).
3. Train check: - Xiaomi often leaves the plume of the speaker after falls.Symptoms: sound disappears when you press the bottom of the body.
4. Diagnostics via code: Enter ##4636##, select Phone Information → Sound Check.

If the speaker is physically damaged, it will cost 800-2000 rubles to replace it at the service center. On models with IP53 (for example, Redmi Note 11 Pro+), the speaker often suffers from moisture, in which case cleaning of contacts is required.

💡

Before visiting the service center, reset the sound settings to the factory (Settings → System → Resetting → Resetting the sound settings). This will eliminate software errors and save money on diagnosis.
