The most obvious way is to use the buttons on the remote, but there are a few nuances that few people know about:

• 🔊 Mute button (with speaker image) – turns off sound only for the current source (HDMI, TV, USB). If you switch the input, the sound can come back.

Disconnecting audio via HDMI-CEC (for external devices)

If you use a TV with a sound panel, receiver or AV-systemically HDMI ARC/eARC, So the sound can be controlled by an external device:

• 🔌 Turn off the cable. HDMI ARC from the TV, it will force back the control of sound on TV.
• 📊 In the TV menu go to Settings → HDMI-CEC and disable the option to control sound through HDMI.
• 🔄 On some models, the Mi TV 5X) need to reset the settings HDMI: Settings → Devices → Reset HDMI.

If the sound is still coming through an external device, check its settings. For example, on the sound panels of the Samsung HW-Q or Sonos Beam, TV SoundConnect mode can be activated, which ignores the commands of the TV.

💡

If the HDMI-CEC has been completely disabling (including HDMI devices), restart the TV by holding the power button on the remote for 10 seconds.

5. Software shutdown of sound for individual applications

Some apps (e.g. YouTube, Netflix, Prime Video) ignore global audio settings due to the fact that they are not able to use the video. DRM-To turn off the sound just for them:

• 🎬 In the app itself (e.g. YouTube), click on the gear icon during playback and select No Sound.
• 🔕 For Netflix and Prime Video, use an external player: download the video via your browser and play it through VLC or MX Player where the sound is switched off separately.
• 🚫 In the models with MIUI TV 3.0+ You can block the sound of the application through Settings → Annexes → Permits → Sound.

2. Use it. ADB Forcing the sound to be turned off: adb shell am start -a android.media.action.SET_VOLUME --es android.media.extra.VOLUME_STREAM 3 --ei android.media.extra.VOLUME_VALUE 0

Hardware shutdown of sound (extreme case)

If the software methods don't work, you have to physically shut down the speakers, and that's true for TVs where sound is played even at zero volume (firmware defect or hardware malfunction).

For this:

1. Remove the back cover of the TV (on models Mi TV 4/5 it is attached to the latches).
2. Find a sound amplifier board – it is usually located next to HDMI or AV connectors.
3. Disconnect the plume going to the speakers (marked as SPEAKER or SPK).

⚠️ Warning: Turning off speakers takes away your warranty.On Xiaomi Mi models TV QLED the amplifier board can be integrated into the main board - in this case, a flashing or replacement of the chip is required TAS5760 (cost ~3000₽).

Alternatively, connect to the audio output (3.5 mm or RCA) stub (resistor 100 ohms) so that the TV “thinks” that the external speakers are connected.

7. Diagnostics of problems: why doesn't the sound turn off?

If none of these methods worked, check the following points:

On the Xiaomi Mi TVs of 2020-2023, a common problem is the conflict of sound drivers after the update. If the sound begins to “disappear” or spontaneously turn on, check the firmware version in Settings → About TV. For models with an Amlogic T972 chip (for example, Mi TV 5X 55), critical sound bugs are fixed in the firmware of MIUI TV 3.0.15+.

💡

If the sound is not turned off by any means, and the TV is guaranteed, contact the service center. The defect may be due to a malfunction of the audio codec (the Realtek ALC5651 chip on models until 2021).
