Audio on a Xiaomi TV can interfere in a variety of situations: while watching a movie with subtitles, when connecting external acoustics or when you use the TV as a monitor for the PC. Unfortunately, many users are faced with the fact that the standard volume reduction through the remote does not always solve the problem – system sounds (alerts, navigation sounds) continue to play. In this article, we will discuss all possible ways to turn off the sound on Mi TVs, Redmi Smart TVs and other models of the brand, including hidden settings and alternative methods.
PatchWall is a feature of the firmware that separates media sound (from videos, apps) and system sounds (notifications, menu clicks), which means that to completely turn off the audio, you need to adjust several settings. We will also tell you how to return the sound if something goes wrong, and warn against common errors that can lead to malfunctions in the TV.
1. Quickly shutting down the sound through the remote control
The most obvious way is to use the volume button on the remote, but there are nuances that few people know about:
- 🔇 Press the Mute button (the crossed-out circle speaker icon) – this will turn off the media sound, but system notifications may continue to sound.
- 📉 Hold the Volume Down (-) button until indicator 0 appears on the screen. TV 4S, Redmi X50) It also blocks the system sounds.
- 🔄 Double press Mute on the latest versions (Mi) TV Stick Remote switches modes: first turns off media sound, then all sounds completely.
If the sound is still playing after these actions, the problem may be in the settings of a particular application (for example, YouTube or Netflix ignore the system volume), in which case move to the next section.
💡
On Xiaomi touchpad remotes (such as Mi TV Remote Pro), the swipe down touchpad gesture also works as a Mute.
2. Turn off the sound in the settings of the TV
For full control of the audio, you need to go to the system menu. The instructions are relevant for all models on PatchWall (including Mi TV Q1, Redmi Smart TV X, etc.):
- Press the Settings button on the remote.
- Go to the Sound section. → Sound settings.
- Select Sound Mode and set the No Sound value (or Off on older versions of the software).
- In the submenu System sounds turn off sliders: 🔔 Navigation sounds (clicks on the menu) 📢 Notifications (notifications from applications) 🎵 Screensaver (music when on/off)
On Android TVs (e.g. Mi TV A2), the path will be different: Settings → Device → Sound → Output → No Sound. Note that after this manipulation, the sound will disappear even when you connect external speakers via HDMI ARC or Bluetooth.

3. Resetting sound settings to factory
If the sound continues to play despite all attempts, there may have been a failure in the audio settings.
Go to Settings → System → Settings → Resetting → Resetting audio settings. After this procedure, all user sound profiles (for example, equalizer settings for Dolby Audio) will be deleted, but the system settings will return to factory values.
⚠️ Note: On some models (Mi) TV 4X, Redmi TV 70) the sound reset also resets the settings HDMI CEC, This could affect the remote control of the sound panel or the receiver.

| Redmi Smart TV X50/X55 | Settings → System → Reset → Sound | Dolby Custom Presets are Shutting Down |
| Mi TV Q1/Q2 | Settings → Device → Sound → Reset | Resetting HDMI ARC settings |
4.Switching off sound for specific applications
Some apps (e.g. YouTube, Prime Video, IVI) have their own volume settings that are independent of system settings.
- 🎬 On YouTube: Open the video → Click on the speaker icon in the lower right corner.
- 📺 In Prime Video: Playback settings → Sound. → Off.
- 🎮 In games (such as Cloud Gaming): There is usually a separate volume control in the game menu.
For applications that don't have a built-in audio-disablement option (like Netflix), you can use a workaround: plug Bluetooth headphones into your TV and turn them off immediately, which will make the app "think" that the audio device is not available and the sound will disappear, but this method does not work on all models.

5. Hardware methods of turning off sound
If the software doesn't work, you can use "physical" switching off the speakers, which is true for TVs where sound is played even at zero volume (for example, due to hardware failure).
Options:
- 🔌 Disabling speakers via service menu (requires technical skills): Enter service code: On the remote, press sequentially: Menu → 1147 → Menu, go to Audio. → Speaker → Off. Save settings and restart the TV.
- 🛠️ Physical Disconnection of Speakers (power users only!): Remove the back cover of the TV (unplug it!) Find the connector going to the speakers (usually marked as SPEAKER or SPK). Disconnect the plume. This will completely and permanently disable the built-in speakers, but leave the ability to output sound through the HDMI/Bluetooth.
⚠️ Attention: Entrance to the service menu and even more disassembly of the TV is deprived of warranty. TV P1 The newer service menu is blocked – you will need special software to access it (for example, Xiaomi). TV Tool).
What if the sound is still going after the speaker is turned off?
6. Alternative methods: external devices and software

Connection to PC
If the TV is used as a monitor, turn off the sound on the computer itself:
Control Panel → Sound → Playback Device → [Your Xiaomi TV] → DisableExternal HDMI switch
Devices like HDMI Audio Extractor allow you to completely cut off the sound at the hardware level, redirecting it to another device (or “nowhere”).
For advanced users, there is another way to turn off the audio via ADB (Android Debug Bridge), which requires connecting the TV to a PC and executing the command:
adb shell settings put system volume_music 0
adb shell settings put system volume_system 0However, this method is temporary - after restarting the TV sound will return.

Frequent Mistakes and How to Avoid Them
When you turn off the audio on Xiaomi TV, users often face typical problems.
- 🔄 Sound returns after reboot: This is due to a failure in PatchWall settings.Solution: After disabling the sound, go to Settings → Annexes → All applications → PatchWall → Stop (then restart the TV).
- 🎧 Sound goes into Bluetooth headphones, but not in speakers: TV remembers the latest audio device. To reset priority: Settings → Bluetooth → Forget all the devices.

If none of these methods worked, check if the TV has third-party software (such as Custom Launcher) that can block changes in sound, and if you want to completely reset the TV to factory settings (Settings → System → Data Reset), you can only use this method if you are ready to reset the TV.
