How to increase the sound on Xiaomi Redmi: Full Guide

Owners of Xiaomi smartphones and the Redmi sub-brand often face a situation where standard volume of multimedia files or speakerphone conversation is not enough, this is especially true in noisy rooms or when watching videos on the road. Standard system settings, such as the volume slider, often have a software limitation designed to protect speakers from overload, but hinders the user.

Fortunately, the MIUI shell and its successor HyperOS provide advanced options for fine-tuning the audio subsystem.There are many methods to get around software limitations and squeeze maximum decibels out of your device, whether it’s a budget Redmi Note or a flagship Xiaomi Pro.

In this article, we will discuss in detail the safe ways to amplify sound through system settings, using an engineering menu and installing specialized software. It is important to understand that excessive volume increase can lead to the speaker wheezing or its complete failure, so all actions must be carried out with caution.

⚠️ Attention: Forced volume increase above factory limits can cause physical damage to the dynamic membrane. Use amplification techniques responsibly and watch for distortion of sound.

Basic setting of equalizer and sound effects

The first and safest step is to set up the built-in equalizer. The MIUI shell allows you not only to select presets, but also to manually adjust the frequencies, which can significantly affect the perceived volume. To access these settings, go to Settings → Sound and vibration → Sound effects.

Here you'll find the Mi Sound Enhancer switch, which can be turned off by default, and activating this feature adapts the sound scene to the type of headphones or speakers used, making the sound more saturated and voluminous. You'll also want to look at the Equalizer tab, where you can choose Rock or Pop mode, which usually have higher scores in medium and high frequencies, which are responsible for intelligibility of speech.

• 🎚️ Turn on Dolby Atmos (if available in your model) by selecting Dynamic profile for maximum volume.
• 🎧 In the Headphones section, select the type of connected device for the correct operation of the amplification algorithms.
• 🔊 Activate the “Voice Clear” option in the call settings so that the interlocutor hears you louder.

Remember, the quality of playback is directly dependent on the audio codec you use, and you can force a developer to choose a codec with a higher bitrate, like LDAC or aptX HD, if your Bluetooth headphones support these technologies, which not only improves the quality, but can also make the sound subjectively louder and more detailed.

⚠️ Warning: Changing the codec settings in the developer menu can cause a Bluetooth connection to work unstable. If the sound is lost or there are delays, return the default settings.

💡

For maximum effect, combine the Mi Sound Enhancer enabled with manual lifting of high-frequency sliders (8k and 16k) in the equalizer.

Use of the Engineering Menu for Calibration

A more advanced method available on many Xiaomi devices is to use an engineering menu, which allows you to change the parameters of the audio track at a low level. To get there, open the Phone app and type the combination ##6484##. If the code does not work, your firmware version may be blocking access, and you will need to use special activation applications.

In the CIT menu that opens, you need to find the audio-related section, which can be called Audio, Speaker, or have a number like [5]. Inside, you'll see a list of tests for different scenarios: speaker, speaker, headphones, select the appropriate test to go to Gain.

So here you'll see parameters like VolStep or HeadsetGain, and you'll turn them up, you'll turn them up, but be very careful, you can overload them, and you'll want to raise them in small steps, and you'll want to check the results after each change.

Volume setting in the developer menu

Android has hidden limits on the maximum volume of Bluetooth devices, which often interfere with the full listening of music through wireless headsets. To remove these restrictions, you need to activate the developer menu. To do this, go to Settings → About Phone and quickly press 7 times on the MIUI version.

Once activated, a new section will appear in the settings menu Additional → For developers. In the list of options, find the item Turn off the absolute volume level. Switching this setting unleashes the volume adjustment of the phone and headphones, allowing you to set the maximum level independently of each other.

Also in this section, you should pay attention to the Bluetooth Codec parameter. Forced selection of SBC codec sometimes gives you a volume increase due to quality, since it is less resource-conscious and has less signal attenuation on some chips. However, for quality sound, it is better to leave the choice automatic or choose aptX.

Application of third-party amplifiers

When the system is not enough, specialized applications from the Google Play Store come to the rescue, with leaders in this niche being Volume Booster GOODEV, Super Volume Booster and Equalizer & Bass Booster, which act as intermediaries, amplifying the digital audio signal before it is sent to the DAC of the device.

When you first run these applications, you'll be asked to calibrate the gain level. It's critical that you don't put the slider on the top of the top. 100% Start with. 20-30% And gradually increase the value by controlling for wheezing. Most apps have a "booster" feature that temporarily increases the volume for a particular track or video.

Some applications require special permissions, such as access to system settings or the ability to overlay on top of other windows, to intercept the audio stream. Always download software only from trusted sources to avoid introducing advertising software.

⚠️ Attention: Boost apps put additional strain on the processor and battery.If the phone starts to heat up strongly during use, stop using the amplifier immediately.

Physical cleaning and speaker maintenance

Often the problem with quiet sound is not software, but the banal pollution of the sound membrane. Dust, pile from pockets and skin fat over time clog the speaker grid, significantly reducing the passing ability of sound, this is especially true for the lower speaker, which is often used as a conversational in modern smartphones.

You can use a soft toothbrush with dry bristles to clean it. Carefully, without pressing too much, walk around the speaker grid in circular motions. A more advanced method is to use a certain frequency sound wave. You can find low-frequency humming videos on the Internet that blow dust out of the speakers.

• 🧹 Use a soft brush to remove visible dust from the mesh surface.
• 🔊 Reproduce a low-frequency track (30-60 Hz) at maximum volume during 1-2 minute.
• 💨 Gently blow the speaker with compressed air (cylinder), keeping it at a distance of at least 5 cm.

If the sound became louder and cleaner after cleaning, then it was the physical obstruction that was the problem. Regular prevention will help to avoid turning down the volume in the future. It is not recommended to use sharp objects such as needles or pins, as they can easily damage the protective net or the membrane itself.

💡

Regular physical cleaning of speakers can return up to 30% of the lost volume without using software.

Problems with Bluetooth codecs and headsets

One of the things that deserves a special attention is that the only thing that you can do is you can only have a quiet sound when you plug in a Bluetooth headset, and in this case, you can have the volume levels between your phone and your headphones, and some headphones have their own volume control system, which is independent of your smartphone.

Try to turn up the volume directly on the headphones (if you have a physical button or sensor), and then add the volume on the smartphone itself. Reconnecting the device also helps: forget the headset in the Bluetooth settings, turn off and turn on Bluetooth on the phone, then pair again.

In rare cases, the problem may be incompatible A2DP profiles. If the sound is still quiet after all the manipulations, try connecting another headset. If the sound is normal with the other headset, then the problem is in the first device, and it may need to be flashed or reset to factory settings.
