How to completely turn off the sound on the TV Xiaomi Mi: all working ways

The sound on the Xiaomi Mi TV can interfere in a variety of situations, from watching movies late at night to using TV as a monitor for PC. Unfortunately, many users find that the standard volume reduction to zero does not always solve the problem - system notification sounds, interface sounds or even voice assistant replicas continue to sound. In this article, we will discuss all possible ways to completely turn off the sound, including hidden settings and workarounds for different Xiaomi Mi TV models.

The feature of the TV series is that it has a multi-level sound system, with separate regulators for media content, system notifications and voice prompts, and if you just pressed the "Mute" button on the remote, it could only turn off the main sound, leaving the rest of the channels active, and then you'll learn how to guarantee that you'll remove all the sounds, including those that are not controlled by standard methods.

Attention! Some methods require changing system settings. If you use a TV in a public place (such as an office or hotel), make sure you have the rights to make those changes, otherwise the settings may reset after the device is restarted.

1. Standard sound shutdown via remote control

The most obvious way is to use the mute button on the remote control, but even here, there are nuances that few people know about.

On most Xiaomi Mi TV remotes, the switching button looks like a speaker with a crossed icon. One tap turns off the sound, the second press turns it back on, but it's important to understand that this only works for the current signal source.

• 📺 If you watch YouTube through the built-in app, the mint will only turn off the sound in it.
• 🎮 If you then switch to HDMI-input (e.g. for a game console), the sound can automatically turn on again.
• 🔔 System notifications (such as low-level alerts) will be played regardless of the meute.

To check if the sound is actually turned off completely, try switching between the signal sources or calling a voice assistant (if activated).

2. Disable the sound through the TV settings menu

If the mute button doesn’t work, the next step is to manually turn off the audio in the settings, a method that works on all Xiaomi Mi TV models, including the Mi TV 4S, Mi TV 5 and Mi TV Q2.

Step instructions:

1. Press the Settings button on the remote.
2. Go to the Sound section. → Sound settings.
3. Find the Volume parameter and move the slider to the left (value 0).
4. Turn off the interface sounds option (if you have one in your model).
5. In the submenu, additionally deactivate Voice prompts and System sounds.

On some firmware (such as Mi TV Stick or older PatchWall versions), the path may be slightly different:

Settings → Device → Sound and vibration → Turn off all sounds

⚠️ Attention: On Android TVs TV 11+ (Like Mi. TV Q1 2023) you may need to turn off the audio separately for each user profile. If you have multiple accounts, repeat the procedure for each user profile.

3. Disabling the sound through the service menu (for experienced users)

If standard methods don't work, you can use the service menu, which is suitable for advanced users, because it requires caution - incorrect changes can lead to malfunctions in the TV.

To open the service menu:

1. Turn off the TV remote.
2. Press and hold the Menu + Volume Down buttons on the remote at the same time.
3. Without releasing buttons, turn on the TV with the power button on the case.
4. Wait for the service menu (usually a blue screen with technical information).

In the service menu, find the Audio Settings section and set the following parameters:

• 🔇 Master Volume → 0
• 🔔 System Beep → Off
• 🎤 Voice Guidance → Disable

⚠️ Warning: Do not change other options in the service menu unless you are sure of their purpose! For example, changing the Backlight or Panel Type values can lead to incorrect screen performance.

4. Disable the sound through the application "Home" (Mi Home)

If your Xiaomi Mi TV is connected to the Mi Home ecosystem (via a smartphone app), you can control the sound remotely, which is convenient if the remote is lost or not working.

Instructions:

1. Open the Mi Home app on your phone.
2. Find your TV in the list of devices.
3. Slap it on and select Control.
4. In the Sound section, move the volume slider to the extreme left position.
5. Activate the option "Do Not Disturb" (if available).

The advantage of this is that it works even if the TV is in a different room.

• 📱 The app must be connected to the same Wi-Fi network as the TV.
• 🔄 Some functions (such as disabling system sounds) may not be available remotely.
• 🔒 If the TV is blocked by a password, you will need to enter it in the application.

5. Hardware shutdown of sound (extreme case)

If the software methods don't work, you have to physically shut down the speakers, which is a radical way to only use if you're confident in your technical skills.

This will require:

1. Turn off the TV and wait for the full discharge of the capacitors (10-15 minutes).
2. Remove the back cover by unscrewing the screws (usually they are hidden under rubber plugs).
3. Find the sound amplifier board – it is usually located next to the speakers (at the bottom of the case).
4. Disconnect the plume or connector going to the speakers (marking may be SPK_L/SPK_R).

⚠️ Attention: Turning off the speakers will void the warranty on the TV! Besides, after this procedure, the sound will not be turned back on without soldering or replacing the plume. If you are not sure of your abilities, you should contact the service center.

💡

Before disassembling the TV, take a picture of the location of all cables and boards, which will help to properly assemble the device back and avoid short circuits.

Frequent problems and their solutions

Even after the sound is turned off, users sometimes encounter unexpected beeps, so let's look at typical situations and how to fix them.

Problem 1: The sound is turned off, but when you switch channels, you get a click.

Solution: This is the system sound of the source switching. Turn it off in the settings:

Settings → Sound → System sounds → Switching sound → Off.

Problem 2: The Google Assistant (or XiaoAI) is still talking.

Solution: Turn off the voice assistant completely:

• 🎤 Go to Settings. → Voice assistant → Shut down.
• 🔍 If the assistant is activated from the remote, check if the microphone button is clamped.

Problem 3: After updating the firmware, the sound turned on itself.

Solution: Reset the sound settings to factory:

Settings → System → Reset settings → Reset only sound

💡

If the sound only appears when connected via HDMI (for example, from a console or PC), the problem may be on the side of the external device. Check the audio settings on the signal source (for example, in the PlayStation or Windows settings).

7. alternative methods (if nothing helps)

If all of the above methods fail, try the following workarounds:

Method 1: Using an external sound card

Connect an external amplifier or sound bar to your TV via HDMI-ARC or optical output, and just turn it off. The TV will think that the sound is being output to the external device, and will not play it through the built-in speakers.

Method 2: Reset the TV to factory settings

The last measure that will return all the parameters of the sound to the original state:

Settings → System → Reset → Full reset settings

⚠️ Warning: This will delete all installed apps, accounts and personal settings. Pre-write down important data (for example, logins from streaming services).

Method 3: Update the firmware

Sometimes the sound glitches are associated with errors in the software. Check for updates:

Settings → About TV → System Update

If the update is available, install it and restart the TV.
