Xiaomi Redmi Note 5 (codenamed whyred) is still a popular smartphone due to its price-performance balance. However, many users are faced with the quiet sound of a conversational speaker β a problem especially noticeable in noisy rooms or when using hands-free. In this article, we will discuss all possible ways to increase the volume, from standard settings to deep modifications of the system.
It's important to understand that the earpiece is physically smaller than the media, so the maximum volume is limited by design, but even within that framework, you can achieve 20 to 40 percent improvements without losing sound quality. We tested all methods on MIUI 10 to 14 firmware and custom builds like Pixel Experience or LineageOS.
Warning: Some methods require unlocking the bootloader or root rights. This voids the warranty and can cause permanent damage to the speaker if you exceed the permissible load.
1. Check hardware limitations before settings
Before you change the software settings, make sure the problem isn't physical damage.The quiet sound of the conversational speaker on the Redmi Note 5 can be caused by:
- π Mesh pollution speaker - dust and fat reduce the amplitude of sound waves. Clean the hole with a soft brush or compressed air.
- π§ Bad plume contact, after falling or disassembling, the body can press the speaker connector.
- π± Mike damage β if the other person is also hard of hearing, the problem may be in the microphone, not the dynamics.
- π Weak power β when the battery is below 15%, the system automatically lowers the volume to save energy.
To exclude software failures, reset the sound settings:
- Go to Settings. β Sound and vibration.
- Select Reset Sound Settings (could be called βRestore Default Valuesβ).
- Reset the device.
β οΈ If after the reset the volume has not changed, and in the settings the slider of sound is fixed by 50-70% (does not move further), this is a sign of hardware limitations - the speaker requires replacement.
2. Software methods of increasing volume without root
If there are no hardware problems, start with secure methods that donβt require superuser rights, which work on standard MIUI firmware and most custom builds.
Enabling the sound amplifier mode in MIUI
The hidden MI Sound Enhancer feature is available on some firmware versions to activate it:
- Open the Phone app and dial the combination: ##36446337###.
- In the menu that appears, select Hardware Testing β Audio β LoudSpeaker Mode.
- Set the value of 1 (included) and save.
This mode increases the volume by 10 to 15 percent, but it can add wheezing at its maximum level. If the sound is distorted, return the value to 0.
2.2.Use of Equalizer and Presets
The built-in equalizer in the Redmi Note 5 allows you to raise the frequencies responsible for legibility of voice.
- Go to Settings β Sound and vibration β Equator.
- Choose a voice or speech (if any).
- Manually lift sliders 1-3 kHz on +3... +5 dB.
To fine-tune, use apps like Wavelet (free on Google Play), which analyzes the characteristics of your speaker and applies optimal filters.

Sound amplification applications
Specialized utilities increase volume by processing the audio stream. The best options for the Redmi Note 5:
- π Volume Booster β Increases volume by 20β30%, but can add noise.
β οΈ Attention: Volume Booster-type applications can overload the speaker if you set maximum amplification. +10% and check the sound for distortion.
| Annex | Max, boost. | Root is required. | Risk of damage |
|---|---|---|---|
| Volume Booster | +30% | No. | Medium. |
| Precise Volume | +15% | No. | Low. |
| Speaker Boost | +25% | No. | High (at max) |
| ViPER4Android | +40% | Yes. | Very tall. |
3. Methods with unlocking the loader (for experienced)
If the standard methods fail, you'll have to go deep, all of which require an unlocked bootloader and are potentially dangerous to the device.
3.1. File editing mixer_paths.xml
This file contains volume limits for all audio devices.
- Get root rights (for example, through Magisk).
- Install a file manager with root support (such as Root Explorer).
- Cross the path: /vendor/etc/mixer_paths.xml.
- Find the rows with the RX1 Digital Volume and RX2 Digital Volume options (responsible for the conversational speaker).
- Increase the max from 84 to 92-95 (not higher!).
- Save the file and restart the phone.
Example of the original line:
<path name="speaker">
<ctl name="RX1 Digital Volume" value="84" />
</path>Corrected version:
<path name="speaker">
<ctl name="RX1 Digital Volume" value="92" />
</path>β οΈ Attention: Exceeding value 95 for RX1/RX2 on the Redmi Note 5 This leads to clipping and the risk of burning the speaker β 88β92.

Installation of ViPER4Android
ViPER4Android is a powerful audio driver that allows you to tune the sound and increase the volume.
- Download the latest version ViPER4Android forum XDA Developers (only for developers) arm64).
- Install the APK and driver via Magisk Module.
- In the application settings, select Speaker Optimization profile.
- Activate Master Limiter and raise Pre-Amp to +3...+5 dB.
ViPER4Android gives you up to 40 percent volume gain, but it requires fine tuning, and the wrong settings can turn sound into an indistinct mush.
π‘
Before installation ViPER4Android Backup the original file /vendor/etc/audio_effects.conf. This will help to restore sound when failures occur.
Hardware modifications (extreme case)
If the software is exhausted, then there's physical intervention, and these methods require disassembling the phone and soldering skills.
Replacement of the speaker with a more powerful speaker
The standard speaker Redmi Note 5 has a resistance of 8 Ohms and power 0.5 W. It can be replaced by:
- π§ Original speaker from Redmi Note 7 - compatible connector, power 0.8 W.
- π Universal Dynamics 8 Om./1 Wh-- like, CUI Devices CDM-16024.
Replacement process:
- Plug off the back cover of the phone (use a plastic shoulder blade and hair dryer).
- Disconnect the battery plume to avoid short circuit.
- Carefully unplug or unplug the old speaker connector.
- Install a new speaker, check the polarity of the connection.
β οΈ Warning: Replacing the speaker with a 4 Ohms resistance model (instead of the 8 Ohms standard) will increase the load on the audio amplifier, which can lead to overheating of the chip and failure of the motherboard.
Power boost speaker (for advanced)
You can increase the voltage on the speaker by modifying the power circuit.
- π¬ A soldering station with a thin sting.
- π Multimeter for voltage testing.
- π οΈ Capacitors with a capacity of 10β22 ΞΌF.
Modification scheme:
- Find an audio amplifier (microchip) on the board MAX98357A or similar).
- Salt the capacitor parallel to the power speaker (between VCC and GND).
- Increase the capacity of the filter capacitor on the power line from 1 ΞΌF to 10 ΞΌF.
Modifying the power chain without calculating the parameters accurately results in the failure of the audio track, a method recommended only for users with experience in electronics.
5. Alternative solutions: when the speaker is not saved
If all attempts to increase the volume have failed, consider alternatives:
- π§ Using Bluetooth headphones β even cheap Xiaomi Mi Basic will give you better sound than the built-in speaker.
If you make frequent calls in noisy places, the best solution is to buy an external noise-canceling microphone (such as the Jabra Speak 410), which connects via Bluetooth or USB-C and provides crystal sound.

Before buying a new phone because of a quiet speaker, check it in store with a test call.Many budget smartphones have a similar problem.
6. Frequent mistakes and how to avoid them
When trying to turn up the volume, users often make critical mistakes.
- π Maximum gain setting in applications β It causes you to distort the sound and risk burning the speaker. +10% and gradually increase.
- π§ Use of incompatible modifications (e.g. firmware) mixer_paths.xml Solution: only take files for whyred.
- π± Ignoring the backup before changes β After a failed modification, the phone may be left without sound. Solution: back up through TWRP.
- π Disassembling the phone without turning off the battery β Solution: always disconnect the battery plume first thing.
Another common problem is firmware incompatibility. For example, if you installed Global ROM on a device designed for China ROM, the sound profiles may not work properly. Check the firmware version in Settings β About Phone β MIUI version.
7. Testing results: how to tell if the volume has increased
After any changes are made, you should evaluate the results.
- π Decibel measurement β Install the Decibel X app and measure the volume before and after the modifications. 3-5 dB increase is already noticeable.
- π΅ Test call β call another phone and compare voice legibility.
- π Playback of the test signal β download the file with a frequency of 1 kHz and check for distortions.
- π Subjective assessment β ask a friend to rate the change in volume on a scale of 1 to 10.
If after the modifications there were side effects (wheezing, crackling, spontaneous volume reduction), return the settings to the original and try another method.
π‘
The optimal volume increase for a speaker is 20 to 30 percent, and the risk of damage to the equipment is greater.
