How to increase the volume of the speaker on Xiaomi Redmi Note 8T: from standard settings to engineering menu

The Xiaomi Redmi Note 8T is a popular smartphone with decent specs, but many users complain about the lack of loudness of the speakers, especially when listening to music in noisy places, watching videos without headphones or while making hands-free calls. In this article, we will discuss all possible ways to increase the volume, from basic settings to working with engineering menus and third-party applications.

It’s important to understand that the physical limitations of the Redmi Note 8T speakers won’t allow for flagship-level sound, but the right settings can make things much better, and we’ll also look at the potential risks of each method and provide safety recommendations.

1. Basic volume settings in MIUI

Before resorting to radical methods, check the standard MIUI settings. Often the problem lies in the wrong settings or system limitations.

Open Settings → Sound and vibration. The following options are available here:

• 🔊 Multimedia volume – regulates the sound in applications (YouTube, Spotify, etc.
• 📞 Call volume - affects the volume of incoming calls. Separately set up Loud in the same menu.
• 🚫 Do not disturb – make sure the mode is turned off or configured correctly (no time limit).
• 🎵 Equalizer – in the section Sound Quality, select Preset Bass or Rock to amplify low frequencies.

Pay special attention to Adaptive Sound (if your version of MIUI has one), which automatically adjusts the volume to the ambient noise, but sometimes it doesn't work properly. Try turning it off and compare the result.

2.Use of the Engineering Menu (MTK Engineer Mode)

The Redmi Note 8T is built on the MediaTek Helio G80 chipset, which gives you access to advanced settings through an engineering menu, which allows you to increase the volume at the hardware level, but requires caution.

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 the Hardware Testing → Audio section.
4. Select LoudSpeaker Mode (or Speaker).
5. In the Value field, increase the current value by 5-10 units (maximum 160 for the Redmi Note 8T, excess is fraught with distortion).
6. Press Set and restart your smartphone.

Make a backup copy of the data|Record the current sound values|Not exceed 160|Use the charger (battery) >50%)-->

⚠️ Attention: Incorrect settings in the engineering menu can cause the speaker to burn out or wheez. If the sound becomes distorted after the changes, return the values to the original values.

3. Sound amplification applications

If standard methods don't work, try specialized applications that work at the software level, amplify sound with processing algorithms, but can slightly increase the load on the processor.

Top.-3 Proven applications for Redmi Note 8T:

To install ViPER4Android on Redmi Note 8T:

1. Download APK from the official website (not from the Play Market).
2. Install the ViPER4Android FX driver via Magisk (ROOT required).
3. In the application settings, select the Headphone/Speaker profile.
4. Activate Master Power and increase Volume Boost to +3-5 dB.

💡

Before installing sound boosters, check for free space on the device – some applications (like ViPER4Android) require up to 500MB for processing cache.

4. Update firmware and clean the system

Sometimes low volume is due to software bugs or system congestion, and updating MIUI to the latest version can solve the problem:

1. Go to Settings → About the phone → System update.
2. Click Check Updates and install the available version.
3. After the update, reset the sound settings: Settings → Annexes → Application management → Settings (⚙) → Resetting settings.

It is also recommended that:

• 🧹 Clear the system cache: Settings → Warehouse → Clear the cache.
• 🚫 Close background applications that consume resources (especially games and instant messengers).
• 🔄 Reboot your smartphone – sometimes it resets volume limits.

If the volume hasn't changed after the update, check the error logs through the Mi Debug app (available in Settings → Additional).

5. Physical methods of improving sound

The problem may not be the settings, but the physical state of the speaker.

Cleaning the speaker:

• 🕳️ Use a toothpick (wrapped with a soft cloth) to remove dust from the speaker grille.
• 💨 Blow the hole with compressed air (a canister for cleaning equipment).
• 🚫 Do not use wet wipes – it can damage the membrane.

Damage check:

• 🔊 Turn on the test sound: ##0673## or ##0289## to diagnose the speaker.
• 🎧 Connect headphones – if the sound in them is loud, the problem is in the dynamics of the smartphone.
• 🔧 If you suspect a hardware malfunction (wheezing, lack of sound), contact the service.

💡

If after cleaning the speaker sound is better, but not perfect - the problem may be the wear of the membrane. 8T Replacement of the speaker costs 800-1500 ₽ service-centre.

Alternative solutions

If none of these methods have worked, consider alternatives:

External speakers:

• 🎤 Connect a Bluetooth speaker (e.g., Xiaomi Mi Portable Speaker).
• 🔌 Use the external USB-C speaker (supported by Redmi Note) 8T through OTG-adapter).

Settings in the annexes:

• 🎬 On YouTube or Netflix, turn up the volume in the app itself (often there is a separate regulator).
• 🎵 In music players (such as Poweramp), activate the ReplayGain option to automatically normalize the sound.

Root solutions (for advanced):

• 🛠️ Install a custom core with modified sound drivers (e.g. FrancoKernel).
• 📱 Change the configuration files in /system/vendor/etc (knowledge).

⚠️ Warning: Root access voids Xiaomi warranty and can lead to a "brick" device if you do not act correctly. Use only proven instructions for the Redmi Note 8T (codename).
