How to increase the volume of the speaker on Xiaomi Redmi Note 8 Pro: safe and effective methods

Xiaomi Redmi Note 8 Pro is one of the most popular mid-range smartphones, but many users are faced with the problem of insufficient loudspeakers. Even at the maximum level, the sound can seem quiet while listening to music, watching videos or talking on speakerphone, the reasons for this lie in both hardware limitations (small speaker size, acoustic camera features) and in the software settings by default.

In this article, we will discuss 7 working ways to increase volume on the Redmi Note 8 Pro, from basic settings to advanced methods using engineering menus and third-party applications. All solutions are tested on current versions of MIUI 12-14 and do not require root rights, unless otherwise noted. Importantly, some methods can affect sound quality or speaker life - we will separately note the risky options.

1. Checking basic sound settings

Before you start to make complex manipulations, make sure the problem isn't in the standard settings.There are a few "hidden" options on the Redmi Note 8 Pro that can limit volume.

Open the Settings → Sound and vibration and check:

• 🔊 Hands-free: Enable the “Amply Sound” option (if available in your version) MIUI).
• 🎵 Equalizer: Choose Preset Bass or Rock – they automatically raise the volume of low and medium frequencies.
• 🔇 Do not disturb: make sure the mode is turned off or configured to allow sound notifications.
• 📱 Adaptive sound: Turn off this feature – it automatically lowers volume in noisy rooms.

Also worth checking is the physical condition of the speakers: clogged grille or damaged membrane can significantly reduce the volume. Carefully clean the speaker holes with a soft brush or compressed air (do not use sharp objects!).

2.Use of the engineering menu (without root)

The Redmi Note 8 Pro has a hidden engineering menu where you can manually increase the volume of the speakers. This method does not require root rights, but changing the parameters can lead to distortion of the sound or overheating of the speakers with prolonged use.

Instructions for entering the engineering menu:

1. Open the Phone app.
2. Enter the combination: ##36446337## (or #4636## for the alternative menu).
3. Go to Hardware Testing → Audio → LoudSpeaker Mode.
4. In the Max Vol field, set the value 160 (usually 140-150 by default).
5. Save the settings and restart the phone.

Important: values above 160 can cause sound distortion at high frequencies and shorten the life of the speakers. If you have wheezing or crackling after the changes, return the parameters to the factory.

3. Sound amplification applications

If the standard settings don't work, you can use third-party apps that are software-enhanced, increasing the amplitude of the audio signal. Below are the proven options for the Redmi Note 8 Pro:

Recommendation: Before installing any booster, check the reviews of Redmi Note 8 Pro users - some apps may conflict with MIUI. Start with minimal amplification (+10-15%) and gradually increase the volume, keeping track of the sound quality.

💡

If the sound becomes hoarse after installing the booster, try turning off the option “Basic Amplifier” in the application settings or reduce the gain level by 5-10%.

4. Update of firmware and sound drivers

Low volume can be due to software bugs in the current version of MIUI. Xiaomi regularly releases updates to fix sound problems.

1. Go to Settings → About the phone → System update.
2. Click on "Check Updates."
3. If a new version is available, download it and install it.

If the update didn’t help, try resetting the sound settings to factory:

1. Open Settings → Applications → Application Management.
2. Find the Sound Settings app (or Music FX).
3. Click on “Storage” → “Clear Data”.

For advanced users, there is an option to flash a custom core with improved audio drivers (for example, Perseus Kernel for the Redmi Note 8 Pro). However, this requires unlocking the bootloader and installing TWRP, which voids the warranty.

5. Hardware modifications (for experienced users)

If the software methods fail, you can consider hardware improvements, and note: these methods require disassembling the phone and can lead to loss of warranty or damage to the device.

Options for hardware sound enhancement:

• 🔧 Replacement of speakers: Install speakers from POCO X3 NFC (Compatible with the connector, but have a large power).
• 🔊 Acoustic camera boost: Glue the phone’s interior cavities with sound-absorbing material (like Dynamat) to reduce resonance.
• 📶 Modification of the amplifier circuit: Replace the capacitors in the speaker power circuit with a model with a larger capacity (requires soldering skills).

To replace the speakers, you will need:

• New speakers (for example, the original from Xiaomi with the MDY-11-EM article).
• A set of T3-T5 screwdrivers and plastic blades for disassembling the body.
• Dryer for softening of glue (temperature not higher than 80 ° C).

⚠️ Note: When disassembling the Redmi Note 8 Pro, it is easy to damage the battery or display plume. If you are not sure about your skills, contact the service center. ~1500–2000 rubles (for 2026).

6. Alternative solutions for specific scenarios

Sometimes the problem of low volume only manifests itself in certain situations, and let's look at the solutions for the most common cases.

🎬 Watching videos (YouTube, Netflix)

In some applications, the volume is limited to the codec level.

• On YouTube, turn off volume normalization: Settings → General → Volume normalization.
• On Netflix, set the maximum sound quality: Settings → Playback quality → High.
• Use an external player (such as VLC) with manual gain settings.

📞 Loud communication during calls

If the speaker is not listening to you in the speaker mode:

• Turn off the Noise Reduction function in call settings.
• Check the microphone for contamination (clean the hole next to the main camera).
• Use headphones with a microphone – they often provide better audibility.

🎮 Games (PUBG, Call of Duty Mobile)

In games, the sound is often muted to save resources.

• In the game settings, enable the option “High quality sound”.
• Turn off the power saving mode to play Settings → Battery → Battery Optimization.
• Use the Dolby Atmos-enabled gaming headphones.

💡

For games, the optimal solution is a combination of external headphones and a sound booster (for example, Equalizer FX with the Preset “Game”).

Diagnostics of speaker malfunctions

If none of these methods worked, there may be a hardware malfunction.

1. Speaker test: In the engineering menu (#36446337##), select LoudSpeaker Test. If there is only one speaker, the problem is in the plume or contacts.
2. Moisture check: Use test strips to determine whether you are getting moisture (under the lid). SIM-If the indicator is red, you need to dry the service center.

Microphone diagnostics:

• Record your voice note and check the quality of the recording.
• If the sound is muffled, the microphone may have clogged or the plume is damaged.

Typical signs of malfunction of the speakers Redmi Note 8 Pro:

⚠️ Warning: If the phone is in a wet environment (such as a bathtub or in the rain), do not turn it on until it is completely dry (minimum 48 hours.
