How to Make Sound Louder on Xiaomi Redmi Note 8 Pro

Xiaomi Redmi Note 8 Pro remains a popular device due to its excellent price-performance ratio, but many users over time notice that the standard volume of speakers is becoming insufficient. This can occur for various reasons: from the software limitations of regional firmware to banal wear of the acoustic system or pollution of the speaker grid. Owners often face a situation when in noisy transport or on the street, the interlocutor is not heard well, and video in the social tape has to listen with maximum hearing tension.

Fortunately, the MIUI operating system that runs the smartphone offers a wide range of options for customizing your audio profile. Unlike many competitors, there are many tools that allow you to not only twist the slider to the maximum, but also adjust the frequency characteristics for a cleaner and louder sound. In this article, we will discuss all the legal and safe ways to help you squeeze the most out of your device without the need to solder or replace hardware components.

Basic settings check and speaker cleaning

Before we go to the complex manipulation of the engineering menu or installing third-party software, we need to rule out the banal physical and software causes of quiet sound. Often the problem lies in the contamination of the output holes of the speakers, which in the Redmi Note 8 Pro model are located at the bottom of the body and at the top (talk speaker). Dust, pile from pockets and skin fat can clog the grid, reducing the volume by 30-40%, which is subjectively perceived as a malfunction.

Also worth checking is whether the "Mono-audio" function or volume limits in special features, which are sometimes turned on accidentally. In the Android audio settings, there is a separate volume control for multimedia, calls, alarms and notifications. Make sure that you adjust the slider that is responsible for the current task, for example, watching a video or playing a game.

  • 🧹 Carefully wipe the speaker grid with a soft dry toothbrush, removing visible dust.
  • 🔊 Check the volume level of the media while playing video by pressing the buttons on the side edge.
  • 🚫 Make sure that no third-party audio device is connected in Bluetooth settings that intercepts sound.

If after a qualitative cleaning and checking all sliders the situation has not changed, it is worth switching to software methods of signal amplification.

Use of built-in equalizer and Dolby Atmos

One of the key features of the Redmi Note lineup is support for Dolby Atmos surround sound technology, which not only creates an ambient effect, but can significantly increase the overall volume of playback. Standard MIUI audio settings often choose the default mode "Original" or "Automatic", which can limit power output for energy efficiency or hearing safety.

To access the advanced settings, go to Settings → Sound and Vibration → Sound Effects. Here you will find the Dolby Atmos switch that you need to activate. Once activated, the system will prompt you to select a profile: Automatic, Video, Music or Games. For maximum volume gain when viewing content, the Video profile is best suited, as it dynamically increases the quiet areas of the track.

⚠️ Note: When activating maximum equalizer profiles and enabling Dolby Atmos, battery consumption can increase by a factor of 5-10%, and also possible appearance of slight distortions (wheezing) at maximum volume in cheap headphones.

Additionally, a graphical equalizer is available on the same menu. To make the sound louder and brighter, it is recommended to choose a preset of "Rock" or "Pop", which usually have elevated high and medium frequencies, perceived by the human ear as louder. Manual tuning of sliders towards increasing the decibels also gives a tangible result, especially if you raise the first three frequency bands.

Try to enable the “Mi Sound Enhancer” feature in the same settings menu if it’s available in your firmware version – it often gives headphone volume up to 20%.

Secrets of the Engineering Menu to Amplify Sound

The most powerful tool for Xiaomi users to interfere with the audio chip at a low level is the engineering menu, accessed through a special code in the Phone application. Entering code ##6484## or ##3646633# (depending on the version of MIUI) will open a hidden testing interface where you can find the Hardware Testing or Audio section.

Inside the audio section, you need to find settings related to LoudSpeaker or Headset, which displays Gain, which is responsible for the level of signal gain. By changing the values in Level fields (usually several, from 0 to 6), you can force the volume limit to be higher than the factory volume limit. Be careful: values above 180-200 can lead to wheezing or failure of the speaker.

☑️ Check before changing the engineering settings

Done: 0 / 4

After making changes, press the Set or Apply button to save settings.Rebooting the device is not always necessary, but desirable for all audio streams to work correctly, a method that bypasses the software limitations of regional firmware versions (e.g., Global ROM), where volume is often artificially low according to EU regulations.

What to do if the engineering menu is not opened?
On some new versions MIUI Access to the engineering menu through the code can be blocked, in which case you can try installing a special application "Engineering Mode" from the Play Market store, which opens the same settings through system intentions."> If Android's built-in tools aren't enough, Google Play apps come to the rescue, which work as software amplifiers, and they process the audio stream in real time, increasing its amplitude. One of the most popular and effective solutions is the Volume Booster application. GOODEV, It has a minimalist interface and allows you to adjust the percentage gain. FX Or Bass Booster. These applications not only raise the overall volume, but also allow you to adjust the compression of sound, which makes quiet sounds louder, preventing clipping at peaks. When installing such programs, the system will request permission to access the microphone or change the system settings of the sound - this is necessary for their correct operation. GOODEV General (Gain) Low (High) High (High) >60% Equalizer FX Frequency + Gain Average Super Volume Booster Aggressive Boost High Very High JetAudio Professional Average Low Use of Third-Party Amplifiers requires caution. 40-50% in most cases leads to the appearance of an unpleasant wheezing and can overheat the speaker coil. On the Redmi Note. 8 It is recommended not to exceed the mark in 30% If the problem of quiet sound is exclusively related to wireless headphones, it may be the selected data codec. Xiaomi Redmi Note 8 Pro supports various codecs, including SBC, AAC, aptX LDAC. Some codecs, such as LDAC, prioritize-rule sound quality and can transmit a signal of lower volume compared to standard SBC. To change the settings, you need to activate the developer mode. Go to Settings → On the phone and press quickly 7-10 once in the field MIUI". After the message "You became a developer" return to the main settings menu, select Additional settings → For developers. Find the Bluetooth Audio Codec section and try switching to SBC Or aptX. Also on the developer menu, you should pay attention to the item "Bluetooth's Absolute Volume." If it's on, the volume of the headphones syncs with the volume of the phone. If it’s off, you can adjust the volume independently, which sometimes allows you to bypass the limits set by the headphone manufacturer. Modification of system files (for advanced) For users with superuser rights (Root), access to editing system files responsible for sound mixing is opened. mixer_paths.xml, directory /system/etc/, It contains amplification parameters for each use case, and changing the values of tags containing the words gain or volume allows you to globally change the behavior of the audio system. This method requires installing a root-access file manager, such as Root Explorer or a root-access file manager. MT Manager.Before making any changes, be sure to back up the original file. XML It can cause the sound in the phone to disappear completely or the device to go into an endless boot (bootloop). ⚠️ Warning: Editing system files voids warranty and risks turning your smartphone into a brick. XML You can restore the system through Fastboot. After editing the file, you need to change its permissions to rw-r.--r-- (644), otherwise the system will not be able to read the changes when booting, and this method provides the most stable and deep result, since the changes are applied at the kernel level, not through software add-ons. 💡The safest way to turn up the volume without the Root rights is to combine setting up the Dolby Atmos equaliser and lightly cleaning the speakers. Frequently asked questions (FAQ) Why After Updating MIUI Often, Xiaomi developers in newer versions of firmware change audio drivers or introduce new security restrictions to meet the regulations of different countries, and the update can reset your personalized equalizer settings to factory ones, which are usually more insecure. Can a quiet sound be a sign of a breakdown? Yes, if the speaker is wheezing, interrupting, or the sound is completely gone even at maximum, it may indicate the plume's drifting away, the contact oxidation after moisture is injected, or the physical wear of the speaker's membrane, in which case software methods will not help. Does the volume affect the protective glass or cover? A tight case can overlap the bottom speaker if its cutouts do not match the body openings. The protective glass does not affect sound unless it covers the speaker at the top of the screen, as is the case with other models. Is it safe to use maximum volume at all times? Constantly operating the speakers at their limits (100% volume with a boost) leads to overheating and rapid wear. It is recommended to keep the volume level in the range of 70-80% to extend the life of the Redmi Note 8 audio components.
