Xiaomi’s modern Smart TVs are famous for their design and functionality, but owners often face one common problem: not having enough loud sound in normal mode. Built-in speakers located in a thin case can’t physically create the powerful sound pressure needed for large rooms. If you’re wondering how to increase the sound on a Xiaomi TV to hear quiet dialogue or enjoy blasts in action movies, you’ll need a comprehensive approach to tuning.
There are many software and hardware ways to get around the limitations of regular acoustics, including the hidden settings of Android TV, external codecs, and the addition of additional hardware, and the right configuration can turn mediocre sound into a three-dimensional theatrical experience without buying expensive systems.
It is important to understand that maximum volume is often limited by software to protect speakers from overload. Forced signal level increase above 100% is possible only through third-party applications or engineering menus, but requires caution to avoid wheezing. Next we will discuss safe methods of amplifying audio.
Basic sound settings in the Android TV system
The first step should always be to check the standard settings carefully. Go to Settings → Sound. This is the main control tool. Try changing the sound mode from Standard to Film or Sport. Sport mode often artificially raises the frequencies responsible for the speakers' speech, which subjectively makes the sound louder and clearer.
Pay attention to the DTS Virtual:X or Dolby Audio feature, if available in your model. Activating these technologies doesn't just add echoes, it redistributes frequency range, bringing quiet sounds to the fore. Some MIUI for TV firmware has a separate "Amprovement of Dialogue" slider, which is mandatory for watching news.
Don't forget the equalizer. Manual frequency adjustments allow you to twist the medium and high frequencies that the human ear perceives as volume. But be careful: over-lifting the sliders will cause digital distortion and wheezing to peak.
💡
If you use Bluetooth headphones or a speaker, make sure that the Bluetooth settings select the aptX or AAC codec to transmit sound without loss of quality.
Use of external audio codecs and formats
The sound quality and volume are directly dependent on which codec uses the signal source. When viewing content through embedded applications (for example, Netflix or YouTube), the TV automatically chooses the format, but when playing files from USB or over the local network through a VLC player or MX Player, the situation is different.
In the settings of third-party video players, you can often find the Audio Boost option, which allows you to raise the volume to 200% and even 300% of the original level, this is a software amplification that can lead to clipping, but in quiet scenes it is the only way out.
If your TV is connected to a receiver or soundbar via an optical output or HDMI ARC, make sure that the PCM or Auto format is selected in the Settings → Sound → Digital Output section. Sometimes choosing a specific encoding format (such as Dolby Digital Plus instead of Stereo) makes the external system work louder.
- 🔊 Use the player. VLC Android – It has a built-in amplifier up to 300%.
- 🎚️ Turn on the Night Mode option in Dolby’s settings if it compresses dynamic range, making quiet sounds louder.
- 📡 Switch the output to "Always" PCM», If the external acoustics are quieter in bitstream mode.
Connecting External Acoustics: Soundbars and Systems
If the software methods don't work, the best solution is hardware improvement. Xiaomi Mi TVs are equipped with an HDMI ARC (Audio Return Channel) connector. This is the best way to connect a soundbar or home theater. HDMI cable transmits sound in both directions, allowing you to control the soundbar volume from the TV remote.
For older or budget models of acoustics, optical output (S/PDIF) is suitable. It provides a clean digital signal, but does not support some modern surround sound formats without compression. Analog output (Mini-Jack 3.5 mm or "tulips") is not recommended, as it is prone to interference and has the lowest volume.
When connecting via Bluetooth, it is important to consider audio delay. For movies, this can be critical if the TV can't compensate for the lag. For music via Bluetooth, latency is not important, and it's a great way to quickly increase the volume of the party.
Third-party applications for sound amplification
The Android TV ecosystem allows you to install applications that take over audio, and one of the most popular solutions is the Volume Control app, or various modifications to the system equalizer, which create a virtual layer on top of the system settings.
These programs are usually installed through the Google Play Store on your TV, and when you start, the app asks for permission to change your system settings. It's important to give you only the necessary permissions. Some utilities require you to connect to your PC through ADB for deep integration, but most work immediately after installation.
⚠️ Note: Install applications from unknown sources (APK-Site files) can cause system instability. Use only verified programs from the official Google Play store.
The effectiveness of these applications varies. They can add 10-15 dB to the maximum volume, but the sound quality often suffers, the bass gets buzzing, and the high frequencies get sharp. Use this method as a temporary solution.
Configure through the Engineering Menu and ADB
For advanced users, it is possible to change the system volume limits through the ADB (Android Debug Bridge) debugging bridge, which requires connecting the TV and computer to the same Wi-Fi network.
First, activate the developer mode. Go to Settings → About device and quickly press 7 times on "Build." Then, in the "Development by USB" menu, turn on "Debug by USB." Then the computer executes a connection command.
adb connect 192.168.1.XX:5555Once connected successfully, you can change the settings (amplifications). However, specific commands depend on the processor (Amlogic, MediaTek, Realtek) installed in your Xiaomi model. There is no universal command, and an incorrect action can lead to a complete absence of sound.

- 💻 Install platform tools ADB computer.
- ⚙️ Enter commands only after learning the manual for a particular model TV.

Table of comparison of reinforcement methods
To make it easier for you to choose the best method, we have compiled a method comparison table that will help you estimate the cost of time, money and expected results.
| Method | Cost | Difficulty | Sound quality |
|---|---|---|---|
| Equalizer settings | Free of charge. | Low. | Average. |
| Applications (Volume Boost) | Free/Paid | Low. | Low (possible distortions) |
| Soundbar Connection (HDMI ARC) | Tall. | Medium | Excellent (Cinema Theatre) |
| Modification through ADB | Free of charge. | Tall. | Good (depending on the setting) |
As you can see from the table, software methods are cheap, but they yield limited results. A hardware solution (soundbar) requires investment, but solves the problem radically and permanently.
Frequent problems and their solution
Sometimes the sound becomes quiet suddenly, after updating the firmware, in which case it helps to completely reset the sound settings to the factory, find the menu item "Reset the sound settings" or perform a general reset of the TV.
Another problem is desynchronizing audio and video when using Bluetooth headsets or when you force through apps, in which case you need to find the audio delay setting in a player (for example, the MX Player) and adjust its value in milliseconds.
☑️ Diagnostics of quiet sound
If the sound is wheezing at maximum volume even after all the settings, it may be that the speakers are physically damaged or the contact of the plume inside the housing has gone away, in which case the software magnification will only kill the speakers.
Recommendations for content selection
Digital TV (DVB-T2) is often broadcast with low bitrate sound, so even a powerful TV will sound flat. Streaming services in 4K HDR usually have Dolby Digital 5.1 tracks that require proper decoding.
When you watch torrents, look for the notes in the file title. Files labeled DTS-HD or TrueHD have more dynamic sound, but your TV needs to be able to process or transmit them to an external system. If the TV doesn't support the format, it can either be silent or play very quietly in stereo.
💡
A comprehensive approach, including setting up an equalizer, choosing the right codec and, if necessary, buying a soundbar, is guaranteed to solve the problem of quiet sound on your Xiaomi TV.
