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

The Xiaomi Redmi Note 8T is a popular smartphone with good specs, but many users complain about the quiet sound of the auditory speaker during calls. The problem is especially relevant in noisy places or when using cheap covers that block the speaker hole. In this article, we will analyze all working ways to increase the volume, from standard MIUI settings to hidden functions of the engineering menu.

It's important to understand that the volume limit is a manufacturer's reason for doing this. Too high a sound level can cause the sound to be distorted, the speaker to overheat, or even the speaker to fail. So we're going to increase the volume within a reasonable range without sacrificing quality. If after all the manipulations, the sound is still quiet, the problem may be the contamination of the speaker, the damage to the plume, or the software failure.

Before you start settings, check: 1) Are there any physical obstacles (dust, cover, film). 2 Is the firmware updated to the latest version of MIUI (new versions often fix bugs with sound). 3 Does the speaker work in other applications (for example, YouTube or Voice Assistant).

If everything is in order, we move on to ways to amplify the sound.

1. Volume settings in MIUI: What can be changed without root

The first thing to try is the standard MIUI tools, which are usually enough to increase the volume of the speaker a little. Open the settings → Sound and vibration and pay attention to the following parameters:

• 🔊 Media Volume – regulates the sound in applications, but indirectly affects the overall volume of the system.
• 📞 Call volume – a separate slider for incoming calls (sometimes reset after updates).
• 🚫 Don’t disturb – check if this mode is activated (it can jam the sound).
• 🎵 Equalizer – in the section Sound quality you can choose Preset "Loud" or manually raise high frequencies.

Pay special attention to the item "Revenge Volume" (if you have one in your version of MIUI). This feature automatically raises volume in noisy conditions, but does not work on all firmware. If you do not have an option, try updating the MIUI or resetting the sound settings to the standard (Settings → Applications → Management → Three points → Resetting).

An important nuance: Redmi Note 8T has a separate volume setting for alarms and notifications, sometimes confused by the volume of the speaker, so that you don't make a mistake, during a test call, adjust the volume with the volume buttons on the sidebar, which directly affect the auditory speaker.

2. Engineering menu: hidden volume settings

If standard methods fail, it’s time to look at the Engineering Mode, which is a hidden Android section where you can manually adjust audio settings, including the maximum volume of speakers. On the Redmi Note 8T, the path to the engineering menu is different from other Xiaomi models — use code ##36446337##.

Once you enter the code, you will be taken to the EngineerMode (MTK) menu. Go to Hardware Testing → Audio → Normal Mode.

Here we are interested in the following parameters (values are indicated for the Redmi Note 8T):

Warning: values above 165 can cause sound distortion or overheating of the speaker. After the changes, be sure to test the sound at different volume levels. If there are wheezing or crackling, return the values to their place.

⚠️ Attention: The engineering menu is designed to test the device. Incorrect settings can cause a failure of the communication module or speakers. If the sound is lost after the changes, reset the settings through Settings. → Additionally. → Resetting settings (not to be confused with a full reset!).

3. Sound amplification applications: what really works

If you don't want to dig into the engineering menu, you can use third-party apps, but be careful: many of the Play Market programs either don't run MIUI or require root rights. We tested several solutions and selected those that are guaranteed to run on the Redmi Note 8T without root:

• 🔊 Volume Booster GOODEV — It increases volume by 20 to 30 percent by optimizing the audio driver. It doesn't require root, but after the update. MIUI may fall off.
• 🎛️ Equalizer FX — It allows you to fine-tune the equalizer by raising frequencies that are better perceived by the ear (1-4 kHz), the effect is not as noticeable as in the booster, but the sound becomes clearer.
• 📱 SoundAssistant (Samsung) — although the app is from Samsung, it also works on Xiaomi, and provides a separate volume control for calls, media and notifications.

How to use boosters correctly:

1. Install the application and give all the necessary permissions (access to notifications, overlay of windows).
2. In the settings, select "Enhance the volume of calls" (not to be confused with the volume of media!).
3. Raise the slider 10-15% of the maximum value (more - the risk of distortion).
4. Reboot your phone to make the changes take effect.

Important: some applications (for example, ViPER4Android) require installation through Magisk and work only on firmware with an unlocked bootloader. If you are not ready for such manipulations, limit yourself to solutions without root.

⚠️ Note: Boost apps may conflict with system services MIUI, If after installing such software, the phone starts to brake or overheat, delete the program and clear the cache in Settings. → Annexes.

💡

Before installing the booster, back up the audio settings via Settings → Additional → Backup. This will help you quickly get everything back if something goes wrong.

4. Cleaning dynamics: when the problem is not in the settings

If the sound suddenly becomes quiet, the reason may lie in the contamination of the speaker. Over time, dust, pile from pockets or particles of skin that form a traffic jam enter the hole. On the Redmi Note 8T, the auditory speaker is located at the top of the screen, next to the front camera - it is easy to score without even noticing.

How to clean the speaker without indiscriminately:

1. Take a soft toothbrush (preferably new or clean).
2. Carefully, without pressure, walk along the speaker grid with movements along the holes (not across!).
3. Use a compressed air can (to clean keyboards) to blow out the dust. Hold the balloon upright so as not to freeze the speaker.
4. Check the sound after cleaning. If there is no improvement, the problem may be in the plume or the speaker itself.

What can't be done:

• ❌ Use needles, toothpicks or other sharp objects – they will damage the speaker grid.
• ❌ Blow the speaker with your mouth – saliva can get inside and cause corrosion.
• ❌ Use liquids (alcohol, water) - this will lead to a short circuit.

If the sound is not restored after cleaning, try to test the speaker through the engineering menu: EngineerMode → Hardware Testing → Audio → Speaker Test.

If the sound is quiet or absent in the test, the problem is hardware (a speaker or plume replacement is required).

5. Update firmware and reset settings

Sometimes a quiet sound is a software bug that fixes in newer versions of MIUI. Check firmware relevance: Settings → About Phone → System Update.

If you have an update, install it, especially if you haven’t updated your phone in a while (MIUI versions older than 12.5 often have audio issues).

If the update didn’t work, try resetting the sound settings to factory: Settings → Apps → Application Management → Three dots (menu) → Resetting the app settings.

This operation will not delete your data, but will return all audio parameters to the standard values.

In extreme cases, you can make a complete reset (Settings → Additional → Reset), but before that, be sure to save important data. Reset helps if the problem is caused by an application conflict or damage to system files.

⚠️ Note: After resetting, some features may need to be re-activated, such as Volume Up in the audio settings, and check if the permissions for booster apps have reset (if you used them).

💡

Updating your firmware and resetting settings is the safest way to return factory volume if the problem is caused by a software failure.

6. Hardware solutions: when nothing helps

If all the software methods have been tried and the sound is still quiet, the problem may be in the hardware.

If you are not sure of your skills, do not disassemble the phone yourself - the risk of damage to the plumes or display is very high. Contact the Xiaomi service center or checked repair. The average cost of diagnosis is 300-500 rubles, replacement speaker - 500-1500 rubles (depending on the region).

How to choose a service:

• 🔧 Check reviews on Yandex.Maps or 2GIS (especially pay attention to complaints on sound).
• 📋 Ask if you have a job guarantee (good services can be provided for 1 month).
• 💰 Compare prices: too cheap repairs can mean using unoriginal parts.
