Many users face the unpleasant situation when, after buying and connecting Xiaomi Mi TV Stick to the TV, the level of audio played is too low, especially when watching movies with original voiceovers or when using applications where the dynamic range is compressed excessively. Standard volume controls are often not enough to compensate for the technical limitations of the built-in audio output or the peculiarities of the acoustics of the TV.
There are several reasons why the sound on Xiaomi Mi TV Stick may seem quiet, from the software limitations of the Android TV operating system to the incorrect settings of the TV itself. It is important to understand that in most cases the problem is solved without having to buy additional hardware. However, in some situations, software amplification has its limits, and ignoring this fact can lead to distortion of the audio stream.
In this guide, we will take a look at all the available volume-boosting techniques, learn how to activate hidden functions, use third-party software, and properly configure external audio devices to produce high-quality and loud sound.
Basic diagnostics and system settings
The first step should always be to check the standard settings carefully. Often users overlook the fact that on Android TV, volume is adjusted in two planes: directly on the console control and on the TV remote. Make sure that both channels are twisted to maximum. It is also worth checking whether the "Night Sound" or "Volume Limiter" mode is activated in the settings menu.
Go to Settings → Device and Accessories → Sound. Here, you should pay attention to the setting “Digital output” or “S/PDIF.” If you have an external audio system connected, choosing the wrong format (for example, PCM instead of Pass-through) can significantly reduce the signal level. For built-in TV speakers, the optimal choice is often automatic definition or PCM format.
Note the equalizer settings. Some versions of MIUI for TV firmware have a built-in equalizer with presets. Modes like "Film" or "News" can artificially lower the overall frequencies, making the sound less saturated and quiet. Try switching to Standard mode or manually lifting the frequency sliders.
⚠️ Warning: Changing the settings of the digital output to the wrong settings can lead to the complete disappearance of the sound. If this happens, reset the audio settings to factory values in the same menu.
Remember that some apps have their own internal volume settings that don’t sync with the system. Check the settings inside the specific streaming service or video player you’re using.
Using third-party applications to enhance
If regular funds are not enough, specialized applications from the Google Play Store come to the rescue. Android TV allows you to install programs that run on top of the system audio stream, amplifying it software. One of the most popular solutions is the “Volume Controller” application or booster-function analogues.
The way these programs work is to add an extra gain to the signal, so you can turn up the volume by 200% or even 300% of the standard maximum, but remember that digital amplification is always distortive, and over-raising can lead to wheezing, especially at low frequencies.
- 📱 Volume Controller GO — Simple application with a widget for quick access and flexible amplification settings.
- 🔊 Sound Assistant – allows you to adjust the volume for each application separately, which is useful if the quiet sound is only in one service.
- 🎚️ Bass Booster & Equalizer – a combined solution for improving low frequencies and overall volume.
To install applications that are not in the official store on the TV, you can use the method ADB load APK-This gives you access to more powerful tools that are not certified for TV-interface, but it works effectively.
Adjustment through ADB and hidden commands
For advanced users, it is possible to fine-tune the audio subsystem through the Android Debug Bridge (ADB) debugging system, which allows you to change system parameters that are hidden from the average user in the GUI. First, you need to activate the developer mode on the console.
To enable debugging, go to Settings → About Device and quickly click on “Build” seven times. Then the “Developers” section will appear in the settings menu. Enable “Debugging by USB” there. Next, you will need a computer and an ADB program connected to the same Wi-Fi network with a console.
adb connect 192.168.1.XX
adb shell settings put system volume_steps_speaker 100This command increases the number of volume steps to make the scale more detailed. You can also try commands to change the maximum level (gain), but they depend on the specific model of the chip and the version of Android. Be careful: wrong commands can lead to unstable system operation.
☑️ Preparation for ADB setting
The Problem of Codecs and Audio Formats
Often, quiet sound is not due to volume per se, but format incompatibility. If you watch high-bitrate content (like Dolby Digital Plus 5.1) and the TV or sound bar only supports stereo, the console may mix channels incorrectly, resulting in a central channel with dialogues that may be drowned out by ambient effects or sound very quiet.
In the Xiaomi Mi TV Stick audio settings, find Volume Sound or Surround Sound. Try switching it from Auto to Off or force it to select Stereo. This will cause the console downmix to convert multichannel to dual-channel in the decoding phase, which often aligns the levels and makes the dialogues louder and clearer.
| Source format | Customization of output | The result | Recommendation |
|---|---|---|---|
| Dolby Digital 5.1 | Auto / Pass-through | Silent sound/No sound | Switch to PCM |
| Stereo AAC | Auto | Normal. | Leave it unchanged. |
| DTS | Pass-through | Noise or silence | Demands externality |
| MP3 | Any | Normal. | No change. |
It’s also worth checking the settings of the video player itself (like VLC or MX Player), which often have a separate mixer that allows you to amplify dialogue channels regardless of background music and effects, and this is especially true for films with poor mixing.
Why does Pass-through make sound worse?
Use of external acoustics and DAC
If software methods do not give the desired result, the only correct solution is to use external devices: output 3.5 mm Mini-Jack on the power adapter (complete with some versions of Stick) or digital output via USB (using an external sound card) allow you to connect active speakers or headphones.
The best sound can be obtained by connecting Xiaomi Mi TV Stick to AV-receiver or soundbar via optical output (using an adapter with a USB or HDMI-ARC, If the TV supports reverse audio, it completely bypasses the TV's weak audio system.
- 🎧 USB DAC — Compact digital-analog converters connected to USB-The port of the console, provide a clean and powerful linear output.
- 🔌 HDMI Audio Extractor is a device that separates video and sound, allowing you to connect a powerful acoustic system.
- 📡 Bluetooth adapters – allow you to broadcast sound to wireless headphones or speakers with their own amplification.
In the case of USB-Sound cards may need to be connected via USB-externally powered hub, as the own power port on Stick may not be enough to operate a powerful port DAC.
⚠️ Note: When connecting external USB-Make sure that the devices are formatted in the file system FAT32 or NTFS Do not require drivers that are incompatible with Android TV.
Hardware restrictions and firmware updates
You can't discount physical wear and tear or software bugs. Older versions of Xiaomi's Android TV firmware may have included bugs that lowered the maximum volume level. Regular system updates are a must-do procedure to correct these errors.
Check for updates in Settings → About Device → System Update. If the automatic search doesn’t find new versions, you can try updating manually by downloading the current firmware image from the official website and installing it through Recovery mode, although this is more difficult for Stick than for conventional TVs.
Sometimes the problem lies in the overheating of the device. - Xiaomi Mi TV Stick is compact and with long-term work in 4K It can get hot, which leads to processor trolling and, as a result, to failures in processing the audio stream. USB-extender.

Importantly, maximum software amplification without loss of quality is achieved only with the use of external acoustics. The built-in speakers of televisions are physically limited by their power and size, and no program can make them sound louder than their design capabilities without severe distortion.

Integrated approach: a combination of output format (PCM) configuration, booster applications and external acoustics gives the best result.
