How to increase the volume of the speaker on Xiaomi Redmi Note 8 Pro

Owners of the Xiaomi Redmi Note 8 Pro smartphone often face a situation where the standard volume of the multimedia speaker becomes insufficient, this can occur in noisy places, when watching videos without headphones or simply because of the individual characteristics of the user's hearing. The device is equipped with a high-quality stereo speaker, but the software limitations of regional firmware can artificially underestimate the maximum power of sound.

Fortunately, the MIUI-enabled Android operating system provides a range of tools to fine-tune your audio output. In this article, we’ll look at safe ways to amplify sound, from basic interface settings to system settings, and learn how to activate the hidden capabilities of your gadget’s audio subsystem without risking damage to the hardware.

Before we take any drastic measures, we need to make sure that the problem is not the usual physical obstacles. Dirt, dust and pile from the pockets often clog the speaker grid, significantly reducing its performance. Cleaning the speaker system is the first and most important step, which is often ignored by users.

Physical cleaning and basic diagnostics

The first thing you need to do is visually look at the bottom end of the device, where the main speaker is located, and the top speaker, and over time, a dense layer of dust accumulates in the holes, which acts as a sound insulator, and you can use a soft toothbrush or a special sticky tape to clean it, carefully removing the contaminants.

After physical cleaning, you should check the settings of the equalizer built into the system. The MIUI shell has a standard graphic equalizer that allows you to adjust the frequencies. If the sliders are lowered down or the silent sound mode is selected, no software boost will help. Make sure that in the Settings → Sound and vibration → Sound effects activated mode "Standard" or "Clear", and the volume slider is twisted to the maximum.

⚠️ Warning: Never use sharp objects such as needles or pins to clean the speaker grid.You may damage the membrane or puncturing the safety net, resulting in irreversible deterioration of sound quality or complete failure of the speaker.

💡

Use paint tape: stick a small piece onto the speaker grid and pull back abruptly, which will help pull the dust out of the depths without mechanical damage.

Setup of System Equalizer and Dolby Atmos

The second step is to fine-tune filters, depending on the firmware version, the Redmi Note 8 Pro can have a Dolby Atmos effect or a standard equalizer MIUI Sound, which allows you to not only increase the overall volume, but also make the sound more saturated and legible.

If you use a standard equalizer, try choosing a preset Rock or Pop, as they usually have elevated mid- and high frequencies, which subjectively makes the sound louder. Also worth paying attention to the Sound Enhancer feature, which is often on the same menu.

For more advanced users, third-party equalizer apps from the Google Play Store are available. Programs like Volume Booster GOODEV or Bass Booster can programmatically amplify the signal above standard system constraints. However, it is worth remembering that excessive digital amplification can lead to wheezing and distortion.

• 🎚️ Open the sound settings and find the equalizer section.
• 🔊 Select a Rock profile or manually lift all sliders up.
• 🎧 Activate the "Sound Improvement" or "Dolby Atmos" function for surround sound.
• 📱 Set a third-party volume booster if the regular funds are not enough.

Using an engineering menu to amplify sound

The most effective way to increase volume is to make changes to system settings through an engineering menu, which allows you to directly control the amplification of the audio signal at the driver level. Access to this menu on Xiaomi devices often requires the use of a special application or code.

You will need the MTK Engineering Mode app (since the Redmi Note 8 Pro runs on the MediaTek Helio G90T processor) or code input in the "caller." After entering the menu, go to Audio → Audio Debugging → LoudSpeaker Mode. Here you will see several columns with digital values responsible for the volume level at different stages.

In the Level column, select a value (usually 0 to 6). In the Max Vol (or similar) field, you can increase the current value. The standard value is often 130-140. Incremental increase to 160-170 units can give a noticeable increase. It is not recommended to exceed 180-190, as this can lead to overloading and rupture of the speaker membrane.

Once you change your values, be sure to press the Set button to save the settings. Rebooting the device is not always necessary, but is desirable to apply the changes to all system sounds. Be careful: improper settings can make the sound hoarse or too sharp.

Third-party booster apps

If you're messing with the engineering menus that seem too complicated or dangerous, you can use specialized software. The app store offers dozens of utilities that create a software layer on top of the system mixer, forcefully raising the signal level, which is the easiest way for inexperienced users.

One of the most popular solutions is the Volume Booster app, Bass Booster, which has a simple interface with one main slider, and once you install it and give the permissions you need, you can spin the booster up to 20 percent, 40 percent, or even 60 percent, and it also allows you to customize the bass boost and virtualizer to improve the sound quality.

⚠️ Attention: Continuous use of software boosters at maximum power significantly reduces the life of the speaker. It is recommended to turn on the boost only when necessary and return the settings to standard for everyday use.

Another useful feature of these apps is the ability to adjust the starting volume, so you can set a rule to automatically set the volume to 100% when you start a media player or YouTube, eliminating the need to turn the buttons every time.

Cleaning the cache and resetting the sound settings

Sometimes the problem with quiet sound is not hardware, but software failure, and accumulated cache of system services or conflicting settings can limit the audio flow, in which case resetting the audio settings to factory values will help.

To do this, go to Settings → Advanced Settings → Recovery and Reset. However, a full phone reset is a radical measure. Try to first clear the cache of the Settings app or media services through the app management menu. Also, switching the region in the phone settings helps: changing the region from Russia to the United States or India will sometimes unlock additional audio profiles.

If the sound became quiet after the firmware update, it is possible that a new version MIUI In this case, you should search the forums for information about a particular version of the software. Often users find a solution in the form of installing Magisk modules (for root rights), which govern configuration files. audio_policy.xml, turn back.

• 🔄 Restart your device in Safe Mode to check for third-party apps.
• 🧹 Clear the media services cache in the application settings.
• 🌍 Try changing the region in your phone settings.
• 💾 Consider the possibility of rollback on the previous version of the firmware.

Prevention and care of dynamics

To keep your Redmi Note 8 Pro happy with loud sound for as long as possible, it is important to follow the rules of operation. The speaker is a mechanical device, and it does not like extreme loads. Constantly listening to music at 100% volume for several hours can lead to overheating of the coil and loss of elasticity of the suspension.

You should also avoid moisture. Even if the phone has spray protection, soapy water or salty sea water can oxidize the contacts of the speaker, which will lead to a decrease in volume or cod. Once moisture is in, the device is better dried, but not with a hair dryer, but left in a dry place.

💡

Regular cleaning of the speaker mesh and moderate use of maximum volume extend the life of the smartphone’s acoustic system for years.

Following these guidelines will help you improve your smartphone’s acoustic performance significantly, and the combination of physical cleaning, proper equalizer tuning, and careful use of the engineering menu will give you the best result.
