How to add sound to your Xiaomi phone: the full guide

Owners of Xiaomi, Redmi and Poco smartphones often face situations where standard media volume or conversational speaker is not enough for comfortable use, which may be due to regional firmware, EU restrictions, or simply individual preferences of the user who wants to get a more powerful and rich sound. MIUI operating system and the new HyperOS provide hidden and explicit tools for fine-tuning the audio stream, which allow you to significantly improve audibility.

Before we go to radical methods, we need to eliminate the banal software glitches or physical obstacles. Sometimes the problem is solved by simply cleaning the speaker grid or switching the Bluetooth codec. In this article, we will discuss all the available methods, from basic adjustment of sliders to using the engineering menu so that you can get the most out of the speaker system of your device.

Basic volume setting in the MIUI and HyperOS interface

The most obvious but often overlooked aspect is the separation of audio streams. In Xiaomi smartphones, audio management is divided into several independent channels: multimedia, ringtone, alarm and system sounds. When you press the volume button, the current stream is adjusted by default. To access all settings at once, press the volume button and tap the arrow or tripod that appears under the slider.

In the menu that opens, you'll see a detailed mixer. Here, it's important to look at the Multimedia slider, which is responsible for video, music and games. Often users accidentally lower it, thinking they've turned down the overall sound, while the volume of the call remains maximum. Make sure that all sliders are twisted to maximum if you need to limit volume in all use cases.

⚠️ Attention: Constant use of maximum volume through external speakers can cause premature wear or wheezing, especially in budget models with plastic body.

And you also need to check the sound effects settings that are built into the shell, which can both amplify and distort the signal depending on the profile you choose, and go to advanced settings to activate virtual surround sound, which subjectively makes the sound louder and more saturated.

• 🎧 Equator: Select Bright or Rock profile to increase high frequencies.
• 🔊 Sound Improver: Activate the function in the settings for automatic correction.
• 🎼 Visualization: Turn off unnecessary animations if they load the processor when playing.

Using an engineering menu to increase the volume limit

One of the most effective ways to add sound to Xiomi's phone is by editing the system limits through an engineering menu, which allows you to raise the maximum volume level above the manufacturer's standard value for safety, but this requires extreme caution, as incorrect changes can lead to distortion or damage to the dynamic head.

To enter the engineering menu, open the Phone app and enter the special code ##3646633##. If the code doesn't work, your firmware version may block this access and you'll need to install a special assistant app from the Google Play store. After you log in to the menu, go to the Hardware Testing tab, then select Audio and AudioDebug.

In the list that opens, you'll find the media playback parameter, which is usually Media or Digital Gain, and you'll see a level scale where Level 0 is the minimum volume and Level 4 or 5 is the maximum volume, and that's what we'll change about the Max Vol for the top level. The standard value is often 130-140, you can neatly increase it to 160-170.

After making changes, be sure to press the Set button to save the settings. Be sure to check the result immediately by turning on the music track. If the sound gets too sharp or wheezing, immediately return the value a step back.

• 📉 Level 0-2: It is not recommended to change, these are quiet levels.
• 📈 Level 4-5: Main levels for maximum volume.
• 💾 Save: Always press Set after each change.

Set up the equalizer and Dolby Atmos

Many modern models of Xiaomi and Poco are equipped with Dolby Atmos technology or their own equalizer Mi Sound Enhancer. These tools not only change the timbre, but can significantly increase the perceived volume due to dynamic range and lifting certain frequencies. They are on the path of adjustment. → Sound and vibration → Sound effects.

In the Dolby Atmos settings, you should select the profile "Automatic" or "Dynamic." In manual mode, you can adjust the equalizer in detail. To increase the volume and clarity of speech in the video, you should slightly raise the sliders in the middle frequency area (1-2 kHz), and for music, high frequencies (10-16 kHz), this will add air and subjective volume without digital clipping.

It’s worth noting that turning on all the effects at once can lead to increased power consumption by the processor. If you notice that the phone starts to discharge faster when playing music, try turning off the less important effects for you, leaving only the basic frequency setting.

💡

To watch movies in noisy places, turn on the Mode "Cinema" in Dolby Atmos - it is specially sharpened for maximum intelligibility of dialogues against the background of loud special effects.

Sound problems in Bluetooth headphones and speakers

It's quite common for the smartphone to have loud sound on its own, and when you plug in a Bluetooth headset, it's quiet, because of the dissynchronization of volume levels between the Android operating system and the headphone data protocol, and it's addressed through the developer menu.

To activate the developer menu, go to Settings → About the phone and quickly press 7 times on the item "Version" MIUI" or "Version." OS". Once you have an activation message, go back to the main settings menu, select "Advanced Settings" and find "Developers" and find the "Absolute Volume Level" option inside the list.

Try to change the state of this switch. If it's on, turn it off, and vice versa. In most cases, Xiaomi devices are helped by enabling this feature, which forces the phone to control the volume of the headphones directly, ignoring their internal limitations. After changing the setting, be sure to reconnect the Bluetooth device.

Also worth checking out is the Bluetooth codec. In the same developer menu, look for the Bluetooth Codec and try switching it to aptX or LDAC if your headphones support these standards, which not only provide better quality, but often more stable signal strength.

Third-party applications for sound amplification

If the system is not enough, Google Play apps like the Volume Booster GOODEV or Equalizer FX come to the rescue. These programs create an additional layer of signal amplification by passing the audio stream through their algorithm before sending it to the speaker, allowing you to exceed the standard 100% volume, bringing the amplification to 140% or higher.

But the use of these boosters has its nuances: First, they can conflict with Xiaomi’s system equalizer, so one of the tools will have to be turned off, and second, applications require permanent permissions to access the microphone or modify system settings, which can affect autonomy.

⚠️ Attention: Booster apps don't do miracles with physics. If the phone speaker is quiet in design, software amplification will only add distortion and wheezing, but it won't make the sound cleaner.

When you first start this software, don't set the gain right away. Start at 10-20% and gradually increase the value by controlling the sound quality. A sharp increase in gain can instantly burn the speaker, especially if you're listening to music with deep bass.

• 📱 Volume Booster: a simple application with one gain slider.
• 🎚️ Equalizer FX: powerful equalizer with support for presets.
• 🔊 Bass Booster: Specializes in low frequencies.

Physical Causes of Silent Sound and Their Removal

And you also have to take physical factors into account, and over time, the speaker grid gets clogged with dust, pocket pile and skin fat, and this creates a natural barrier to the sound wave, lowering the volume. 30-40%. Visually, the pollution may not be visible, but acoustic resistance increases significantly.

Use a soft toothbrush or a special sticky tape (gel cleaner) to clean the speaker hole, and try not to damage the membrane. You can also use compressed air, but you need to blow at an angle, not perpendicularly, so as not to drive the dust even deeper into the case.

Another reason could be a case. Some protective cases, especially thick ones or with the wrong perforation, can block the output of sound. Take off the case and check if the volume changes. If so, pick up an accessory with wider cutouts.

💡

Regular cleaning of the speaker grid is the safest and most effective way to return factory volume without the risk of software failures.

In rare cases, a quiet sound indicates a malfunction of the speaker or plume. If after all the software settings and cleaning, the sound remains quiet and hoarse even at maximum settings, you may need to replace the audio module in the service center.
