How to Turn Off Audio on Xiaomi TV: From System Sounds to Voice Assistant

Xiaomi TVs (Mi TV, Redmi Smart TV, Xiaomi TV A/S/Q) often give out unexpected audio signals, from an annoying voice assistant to system alerts when switching channels. If you need to completely turn off the audio — whether temporarily (for example, to watch movies with subtitles) or permanently (get rid of audio cues) — this instruction covers all possible scenarios.

Unlike the standard volume reduction remote, here we will analyze the deep settings of the system, including disabling:

• 🔇 All sound (including HDMI-inputs and applications)
• 🤖 Voice Assistant (Google Assistant or XiaoAI)
• 🔔 System alerts (button clicking sounds, network errors)
• 🎵 Background music in the menu and screensavers

The instructions are valid for MIUI TV 3.0-5.0 firmware (2020-2026) and are validated on Mi TV 4S, Redmi Smart TV X50, Xiaomi TV Q2 75.” If your TV is released before 2019, some menu items may differ – use the FAQ section for clarification.

1. Quickly shutting down the sound remote (temporary solution)

The easiest way is to use the Mute button on the remote, but this method has limitations.

• 🔄 The sound will recover when the TV is restarted.
• 🎮 Doesn't work for sounds from HDMI-ports (for example, from a console or sound panel).
• 📢 Does not disable voice prompts Google Assistant.

To temporarily silence the TV:

1. Press the Mute button (the speaker icon with a crossed circle) on the remote.
2. To return the sound, press Mute again or increase the volume with the Volume +/- buttons.

⚠️ Note: Some Xiaomi remotes (e.g. for Mi) TV There is no Mute button. In this case, use the button OK + Hold Volume for 3 seconds.

💡

If the remote is lost, you can turn off the sound via the Mi Remote mobile app (available for Android/iOS). Select the TV model → click the speaker icon in the upper right corner.

2. Completely shutting down the sound in the system settings

If you want to completely remove the sound (including system signals), follow the following steps:

1. Open Settings (cog in the upper right corner of the main screen).
2. Go to the Sound section → General sound settings.
3. Select Sound Mode. → No sound.
4. Turn off the sliders: 🔊 Systemic sounds 🎶 Navigation sounds (when moving through the menu) 🛠 Notification sounds

OK

This method turns off sound globally, including apps (Netflix, YouTube) and external devices (configures, sound bars). To return sound, repeat the steps and select Stereo or Dolby mode.

3. Disable the voice assistant (Google Assistant / XiaoAI)

Voice assistants on Xiaomi TV are often activated randomly (for example, by pressing the Microphone button on the remote or by voice commanding "OK, Google").

For Google Assistant:

1. Press the Microphone button on the remote for 5 seconds → the assistant menu will appear.
2. Select Settings → Google Voice Assistant.
3. Turn off the Google Assistant slider.
4. Confirm the action by clicking Disable.

For XiaoAI (on Chinese firmware):

Settings → Smart Home → XiaoAI → Disable voice control

⚠️ Note: On TVs with firmware for China (CN ROM) Disabling XiaoAI may cause some functions (such as smart home management) to fail, in which case we recommend resetting to factory settings (see Section 6).

4. Disabling sounds in specific applications

Some apps (e.g. Netflix, YouTube, Prime Video) ignore the global audio settings to silence them:

For YouTube:

1. Open the YouTube app.
2. When playing the video, click OK → select the speaker icon.
3. Move the volume slider to the extreme left position.

For Netflix:

On Netflix, sound is only turned off via the remote (Mute button) or system settings (Section 2).

For in-app advertising:

Commercials on MIUI TV Launcher or streaming services are often played with sound, even if the main sound is turned off.

• 🔕 Install a third-party launcher (for example, ATV Launcher through Settings → Annexes → Unknown sources.
• 📵 Turn off the internet on your TV (see Section 5).
• 🛑 Use the settings. → Annexes → [Title of the annex] → Stop it.

5. Disabling sound through network reset or developer mode

If the sound is not turned off in standard ways, the reason may be:

• 🔄 Firmware failure after update.
• 📡 Conflict with connected devices (sound panel, soundbar).
• 🤖 Activated mode for visually impaired (voice support of all actions).

Try the following methods:

Resetting network settings:

Sometimes the beeps are associated with Wi-Fi connection notifications or network errors to reset:

Settings → Network and Internet → Additional → Resetting network settings

Developer mode:

Turn on the developer mode and turn off the audio debugging:

1. Go to Settings. → On TV.
2. Click 7 times on the build number (you will be notified "you became a developer").
3. Go back to the Settings → Additional → Developer settings.
4. Disable: Sounds when pressed Audiomonitoring Debugging over USB (audible signals)

⚠️ Attention: In Developer Mode, you can accidentally change critical settings (e.g., Do Not Save Actions) that will cause the TV to reset. Do not edit settings unless you are sure of their purpose.

Extreme measures: reset to factory settings

If the sound is not turned off by any means, it leaves the TV completely reset, which will delete all settings, accounts and installed applications, but return the system to its original state.

Before discharge:

• 📝 Write down logins/passwords from services (Netflix, Google Account).
• 📷 Take a picture of the current screen/sound settings.
• 🔌 Disable external devices (flash drives, hard drives).

Resetting instructions:

Settings → Device → Resetting → Erase all data


(Put PIN-code if requested)

After discharge:

1. At the initial setup stage, select No Sound in the Sound Settings section.
2. Do not connect to Google account if you do not want to activate Google Assistant.
3. Install apps manually, avoiding automatic updates (they may return sound notifications).

💡

Resetting to factory settings is the only way to remove preset system sounds (such as the melody of the Xiaomi screensaver) that are not disabled via the menu.

7. Hardware methods of turning off sound

If the software methods don't work, you can physically turn off the speakers or the sound chip, which is an extreme measure, requiring disassembly of the TV and loss of warranty.

Turning off the speakers:

In most Xiaomi TV models, speakers are connected via a connector on the motherboard to turn them off:

1. Turn off the TV and disconnect the power cable.
2. Remove the back cover (a plastic shoulder blade or screwdriver will be required).
3. Find the wires going from the speakers to the motherboard (usually marked as SPEAKER_L/R).
4. Take care to remove the wires (do not cut them!).

Turning off the sound chip:

On some models (for example, Mi TV 4X) sound is processed by a separate chip Realtek ALC or ESMT. It can be turned off by moving the jumper to the OFF position (motherboard circuitry is required).

⚠️ Warning: Disassembling the TV will void the warranty and may damage the board.If you are unsure of your skills, contact the Xiaomi service center to turn off the sound software (they have access to the engineering menu).
