How to turn off audio programs on the TV Xiaomi Mi: all working methods

Sound from an app on a Xiaomi Mi TV can get in the way when you want to focus on other content or just silence. For example, background music from YouTube, ads on Netflix or audio notifications from Prime Video often require an urgent shutdown. Unlike smartphones, where there is enough swipe down to control sound, on set-top boxes and smart TV, the interface works differently.

Complicating the problem, Xiaomi uses several operating systems depending on the model: MIUI TV (for most Mi TV 4A/4S/5X), Android TV (for Mi Box S and new models), and Google TV (on the latest versions of the firmware). The methods of turning off sound vary — somewhere enough buttons on the remote, and somewhere you have to dig into the settings of the application. In this article, we will analyze all the current methods, including the hidden function of muffling for individual applications in MIUI TV 3.0+, which is not written in the official documentation.

1. Quickly shutting down the sound with the remote buttons

The most obvious way is to use physical buttons on the Xiaomi Mi Remote remote, but there are nuances:

• 🔊 The Mute button (with the speaker) mutes all the sound of the TV, including system notifications.
• 📻 Volume – – reduces volume to 0, but does not turn off the sound completely (on some models there is background noise).
• 🎵 Combination "Menu" + Volume -" on Mi TV 4S and Mi Box holding these buttons for 3 seconds turns off sound only for the current application (does not work on all firmware).

If your remote does not respond to buttons, check:

1. Replace the batteries (even if the light is on).
2. Restart the TV: Settings → Device → Reboot.
3. Reset the remote: pinch Netflix + Back for 5 seconds (for Mi Remote Pro).

2. Disable the sound through the application settings

Many apps (e.g. YouTube, IVI, Kodi) have their own audio settings.

1. Open the app, the sound of which you need to turn off.
2. Press the Menu button (three dots or gear) on the remote.
3. Select Settings → Sound or Audio Settings.
4. Set the volume slider to 0 or activate the Mute option.

On Mi TV with MIUI TV, the path may be different:

Application settings → Additional → Sound Management → Turn off sound for this application

Make sure the app is updated | Check your internet connection (some settings require networking) | Remember the current sound settings in case of a return |Reboot the app after changes

-->

⚠️ Note: In some applications (e.g. Disney)+) sound settings are blocked DRM-In this case, only system shutdown will help (see next section).

System-based audio switching off for individual applications (MIUI TV 3.0+)

Starting with the firmware MIUI TV 3.0 (installed on Mi TV 4A 2020+, Mi TV 5X and later), there is a hidden function of sound management at the OS level.

1. Go to Settings → Applications → Application Management.
2. Select the appropriate app (e.g. YouTube).
3. Press Permissions. → Sound and vibration.
4. Turn off the sound play switch.

⚠️ Warning: After disabling the sound through system settings, some applications (such as Twitch) can automatically turn it on the next run:

Settings → Applications → [Select App] → Storage → Clear Data

4.Use of the "Do Not Disturb" mode

The Do Not Disturb (DND) feature on Xiaomi Mi TV blocks all sounds, including notifications and app sound.

1. Go to Settings. → System system → Don't disturb.
2. Turn on the switch.
3. Select Set a schedule if you want to turn off the sound for a certain time.

The downside is that all sounds, including system sounds (such as low-power alerts) are turned off, but this is the only way to completely mute the TV on models without MIUI TV 3.0.

On the Mi Box with Android TV, the path is different:

Settings → Device → Sound → Do not disturb

💡

If the Do Not Disturb mode doesn't persist after the reboot, check the power saving settings. On some firmware, Xiaomi resets the DND when it upgrades or fails. Solution: turn off Settings → Power → Energy Saving.

5. Disable audio via ADB (for advanced users)

If the standard methods don’t work, you can use Android Debug Bridge (ADB) — A tool for managing Android devices via a computer, and that's true for Mi Box and Android TV. TV/Google TV.

Instructions:

1. Turn on USB Debugging on your TV: Settings → Device → Info → Assembly Number (click 7 times) Settings → Device → USB Debugging → Enable
2. Connect the TV to your PC via USB (or Wi-Fi if supported).
3. Open the command line on your computer and type: adb shell settings put global zen_mode 1 (This activates the "Do Not Disturb" mode programmatically).
4. To turn off the sound for a particular application (e.g. com.google.android.youtube), use: adb shell appops set com.google.android.youtube AUDIO_MUTE allow

⚠️ Attention: Wrong commands ADB You can disrupt your TV. Before experimenting, back up your settings through Settings. → System system → Backup.

💡

ADB-Teams only work on TVs with an unlocked bootloader. On some Xiaomi models (e.g. Mi). TV P1) debugging USB Disabled at the firmware level and requires root rights.

6. Alternative solutions: switching off the sound at the source

If none of the above has worked, consider these options:

• 🔌 Turn it off. HDMI-ARC: If the sound is coming through the sound bar or receiver, check the settings. HDMI-CEC In Settings → Sound. → HDMI. Turn it off. ARC Control.
• 📱 Smartphone Control: Install the Mi Remote app (available for Android and iOS) and use a virtual remote to muffle the sound.
• 🔇 Physical switching off speakers: On some models (e.g. Mi) TV 4S 55") you can disable the built-in speakers via the service menu (input by code 1999 in the settings menu).

For Mi Box owners, there is another life hack: if the sound is coming through Bluetooth headphones, just turn them off in the settings:

Settings → Devices → Bluetooth → [Select Device] → Disable

7. Frequent problems and their solutions

Sometimes the sound keeps playing despite all the manipulations, and let's look at the typical scenarios.

If the problem persists, check the TV for viruses (yes, they do happen on TV!).

1. Install an antivirus (such as Malwarebytes for Android TV).
2. Scan the system.
3. Remove suspicious apps in Settings → Security → Threats.
