Modern Xiaomi and Mi TVs, which run on Android TV or PatchWall, offer users a wide range of multimedia capabilities. However, sometimes it is necessary to completely disable audio, whether for nighttime viewing of movies without headphones, eliminating annoying system sounds of the interface or solving technical problems. Understanding how to manage sound streams is a key skill for comfortable operation of smart equipment.
In this article, we will take a look at all the available audio output control methods, from the banal volume reduction to the deep system settings that allow you to completely drown out the device. Turning off the sound may be required in various use cases, and each of them has its own implementation features. We will look at the regular remote controls, operating system settings, as well as specific features for people with disabilities, which often include voice support.
In addition, issues of software failures will be addressed when the TV continues to emit sounds despite the set settings. The digital signal processors in Xiaomi TVs allow you to configure the audio output flexibly, but sometimes require manual intervention of the user.
Basic methods of turning off sound through the remote
The most obvious and quick way to remove audio is to use buttons on the remote control. Most Xiaomi Mi TV and Mi Box models have a separate volume control button, as well as key combinations to instantly block audio. Pressing the volume down button to the end usually results in the icon of the crossed-out speaker on the screen, indicating the transition to Mute mode.
However, if standard methods don’t work or the remote is faulty, alternative options can be used. Many users are unaware that prolonged retention of certain buttons can cause an extended menu of audio settings, and it’s also worth checking whether the “Silence” mode in quick access, which is often hidden in drop-down interface panels, is activated.
- 🔇 Press the volume button several times before the “no sound” icon appears on the display.
- 📱 Use the Mi Remote or Google Home app on your smartphone to programmatically turn off audio.
- ⚙️ Press the button “Menu” or “Settings” on the remote to call the context menu with quick access to audio.
- 🎧 Connect the headphones to a 3.5mm jack, which will automatically turn off the TV's built-in speakers.
Importantly, some versions of PatchWall have voice-activity confirmation that can play back sounds even when the main sound is off. To be completely silent, you need to check the special features settings, as discussed below. Full software shutdown of speakers through the engineering menu is possible only if root rights are available, which is not recommended for ordinary users.
Customization of system interface sounds in Android TV
The Android TV operating system on which Xiaomi TVs are based allows you to flexibly adjust the audio of user actions. Often annoying clicks when switching menu items or notification sounds can be turned off without affecting the volume of the main media stream.
The path to the options you need may vary slightly depending on the operating system version and regional firmware. Most of the time, follow the Settings → Device and Preferences → Special Features or Settings → Sound → Additional settings. Here you can find switches that are responsible for system sounds, which often remain active by default.
☑️ Checking the sound settings
Disabling system sounds is especially important for those who use the TV as a monitor or background. The interface's sound effects can interfere with the perception of the main content, and it is also worth paying attention to the settings of specific applications, such as YouTube or Netflix, which may have their own priorities for playing audio over the system.
⚠️ Warning: When you turn off system sounds, you may stop hearing important system warnings, such as low battery signals or peripheral connection errors.
If you use external acoustics through an optical output or HDMI ARC, Make sure that the correct format is selected in the audio output settings, for example, PCM Or Auto, to avoid conflicts where the TV can continue to give sound to the built-in speakers, sometimes it helps to completely reset the audio settings to factory values through the Settings menu. → Sound. → Resetting the sound settings.
How to disable voice and talkback
One of the common reasons users are looking for a way to “remove the sound” is the randomly activated voice action feature known as TalkBack or Screen Narrator, which is designed for visually impaired users and begins to comment in detail on each button press, making controlling a Xiaomi TV extremely uncomfortable for the average viewer.
To deactivate this mode, you need to get into the special features menu. Since the navigation with TalkBack enabled is changed (double tap to activate and swipe to move), the easiest way to use a voice command is if the remote supports voice input by saying "Stop TalkBack." An alternative method is to quickly log in through the volume button: on some Xiaomi models, triple tapping the volume button turns on or off this mode.
If voice control doesn’t help, follow the following steps through the menu:
- Go to Settings.
- Select the Accessibility section.
- Find TalkBack or Screen Narrator.
- Switch the slider to the off position and confirm the action.
Sometimes the voice function is built into the PatchWall shell and is called Voice Assistant or Audio Description, in which case you should look for the appropriate item in the user's language or profile settings. Deep integration of Google services may also require you to disable the Google Assistant voice assistant in the appropriate settings section to stop unwanted audible system reactions.

Use of external audio devices and switching outputs
To completely eliminate sound from the built-in speakers of the Xiaomi TV without losing the ability to visually control the device, it is often advisable to redirect the audio stream to external devices. This may be necessary if the built-in acoustics are defective, cause background noise or simply do not meet the user's requirements for sound quality. Current models support Bluetooth connection, optical output (S/PDIF) and a 3.5 mm connector.
When you connect your headphones through a 3.5mm minijack, the TV automatically switches the output and silences the internal speakers. This is the perfect solution for night viewing. If you want to transmit the sound to an external speaker or receiver, you need to set the digital output correctly. From the Settings → Sound → Output, you should select the appropriate interface, such as Optical Output or Bluetooth.
| Type of connection | Sound quality | Delay (Latency) | Recommendation |
|---|---|---|---|
| 3.5 mm (AUX) | Medium (analogous) | Minimum | For headphones and old speakers |
| Bluetooth | High (Digital) | Possible delay | For wireless headphones |
| Optics (S/PDIF) | High (Digital) | Absent. | For home theaters |
| HDMI ARC | Maximum. | Absent. | For soundbars and AV-receivers |
When using Bluetooth headphones, it is important to consider possible audio and video dissynchronization. In the Xiaomi TV sound settings, there is often a “Delay Correction” or “Game Mode” option that helps synchronize streams. If the sound is still running parallel through the TV speakers, check if the Duplication mode is set in the audio output settings.
💡
If you use Bluetooth headphones, try to keep them no more than 3-5 meters away from the TV and avoid wall obstructions to minimize sound lag.
Solving Sound Sticking Problems and Software Glitches
Users sometimes face a situation where the sound on the Xiaomi TV is not switched off programmatically, or, conversely, the device makes sounds when the volume is turned off. Such anomalies are often associated with software failures of the Android operating system or conflicts of running applications, in which case simple channel switching does not help, deeper intervention is required.
The first step should always be to fully restart the device, not just to put it into sleep mode. To do this, turn off the TV from the remote, and then disconnect it from the power grid for 1-2 minutes. This will reset the system cache and reset the state of the audio drivers. If the problem persists, check for firmware updates in the Settings → About TV → System Update.
Often, the cause of phantom sound is background applications or advertising modules in free versions of programs.
- 🗑️ Clear the cache and data of the problem application through the application management menu.
- 🚫 Remove newly installed programs that may conflict with the audio system.
- 🔄 Perform reset of sound settings to factory values.
- 🔌 Turn off all externals USB-devices other than the remote control to exclude their influence.
⚠️ Attention: If the TV emits a high-frequency squeak or crack even in the absence of a video signal, this may indicate a malfunction of the hardware (power supply or control board), and not a software failure.
In rare cases, turning off the Auto Volume Leveler feature, which may not work properly with certain signal sources, is in advanced audio settings, and it’s also worth checking the equalizer settings — sometimes twisted to maximum frequency can create the illusion of constant background noise.
💡
Periodic restart of the TV with complete de-energization is an effective method of preventing software failures of the audio system in devices based on Android TV.
