How to turn off the audio program on the Xiaomi TV: all the ways

Xiaomi TVs (Mi TV series, Redmi Smart TV, Xiaomi TV A Pro) offer flexible audio settings, but sometimes users need to turn off the audio completely - whether to watch video without sound, eliminate interference or save energy. Unlike simply reducing the volume to zero, a complete shutdown of the audio stream may be required in specific scenarios: when connecting to external acoustics via HDMI ARC, using the TV as a PC monitor or when testing equipment.

In this article, we will discuss 5 proven ways to turn off sound on a Xiaomi TV, from basic (via the remote) to advanced (via the engineering menu).We will focus on the nuances for different versions of MIUI TV firmware (including MIUI TV 3.0 and later) and models with MediaTek and Amlogic processors. If you encounter a problem when the sound “disappears” on its own or does not turn off through standard methods, here you will find solutions.

1. Quickly shutting down the sound with a button on the remote

The most obvious, but not always effective way to use the Mute button (🔇) Xiaomi TV Remote. But this method has pitfalls:

• 🔄 Temporary shutdown: the Mute button only mutes the sound to 0%, but the audio stream continues to be transmitted (this is important for devices with a high-speed audio system). HDMI CEC).
• 🔊 Exceptions: on some models (e.g. Mi) TV 4S 55′2020) Mute button is reset after switching channel or signal source.
• 🎮 Game mode: if the TV is connected to the console (PS5, Xbox or PC, audio can automatically recover when a game is launched.

To record the sound blackout through the remote:

1. Press Mute once (an icon will appear) 🔇 screen-on).
2. Hold the Mute for 3 seconds – on some firmware, this blocks automatic volume recovery.

⚠️ Attention: Some firmwares reset their sound settings after the update. If the sound returned after the TV restart, check the Reset section. → Sound reset.

3. Disconnecting the sound for a specific source (HDMI, USB, TV)

If standard methods don’t work (e.g., sound comes back after a reboot), you can use a service menu, which is suitable for experienced users and can cause malfunctions if you do not perform properly!

Instructions for TVs on a MediaTek processor (most Xiaomi models):

1. Turn off the TV and wait 10 seconds.
2. On the remote, press sequentially: Menu → 1 → 1 → 4 → 7 → Menu
3. The engineering menu will open. Go to Audio → Audio Output.

Settings → About TV → Press 5 times on "Version MIUI TV" → Service menu → Audio → Disable Audio Output

⚠️ Warning: Changes to the engineering menu may result in a loss of warranty or unstable TV performance.Do not change other settings unless you are sure of their purpose!

5. Disable audio via the Mi Home app (for smart TVs)

If your Xiaomi TV is connected to the Mi Home ecosystem (e.g., Mi AIoT-enabled models), you can control the sound via the mobile app:

1. Open the Mi Home app on your smartphone.
2. Select your TV from the list of devices.
3. Go to the Control section → Sound.
4. Activate the No Sound option or move the volume slider to 0.

If Mi Home doesn’t have audio management options, upgrade to the latest version or reconnect your TV to your Xiaomi account.

Hardware shutdown of sound (extreme case)

If software methods don't help (for example, because of a firmware failure), you can physically turn off the speakers.

1. Turn off the TV and wait 30 minutes (discharge the capacitors).
2. Remove the back cover (you will need a Torx T5/T8 screwdriver for most Xiaomi models).
3. Find the audio amplifier board (usually marked as AMP or AUDIO).
4. Disconnect the plume going to the speakers, or remove the fuse (if any).

Warnings:

• ⚡ Danger of electric shock: even a switched-off TV can store charge in capacitors.
• 🔧 Loss of warranty: opening the hull will void warranty obligations.
• 🔊 Loss of functionality: after switching off the speakers, the sound will not work even through the HDMI ARC Bluetooth.

An alternative is to connect an external sound card via USB or HDMI and configure it as the main audio device, and disable the built-in speakers programmatically.

💡

Hardware shutting down the sound is an irreversible process for most users. Before disassembling the TV, try all the software methods or contact the service center.
