You turned on your favorite movie, but suddenly the call rang out — and the Mute button on the remote from Xiaomi TV somewhere gone? Or maybe you just bought a Mi TV 5 Pro, and the manual in Chinese does not help with the control of sound? This situation is familiar to many owners of Xiaomi equipment, where the design of the remotes often changes from model to model, and the usual keys move to unexpected places.
In this article, we will not only show where the Mute button is on Xiaomi TVs (including the popular Mi TV 4A, 4S, A2, P1 and Q2), but also reveal alternative ways to turn off the sound — from voice commands to smartphone control. And also analyze the typical problems: why the button may not work, how to reassign its functions and what to do if the remote is lost. Spoiler: on some Xiaomi models, the Mute button is hidden under double pressing the volume key — this is not even written in the official manuals.
Before you rush to look for a button, make sure your TV is not in Game Mode or Dolby Audio mode — these settings sometimes block the standard audio management functions. And yes, if you have a Xiaomi TV Stick or a projector (like Mi Projector 2 Pro), the instruction will also work: the control principles are identical there.
1. Standard location of the Mute button on the remotes of Xiaomi TV
On most Xiaomi remotes, the Mute button is located at the top, next to the Volume +/- keys. However, its appearance may vary depending on the model of the TV and the year of release.
- 📺 Mi TV 4A/4S (2018–2020 Mute button looks like a speaker with a crossed icon (🔇) It is located between the Volume and Volume buttons. +.
- 🎮 Mi TV 5 Pro / Q1E (2021–2023: The button is integrated into the touchpad on the right – touch the speaker icon to turn off the sound.
- 🔄 Mi TV A2 / P1 (2023-2026: The Mute button is physically missing! instead, double-pressed Volume – (more in the next section).
- 🖥️ Xiaomi TV Stick/Projector: The Mute button is located on the side panel of the remote, often combined with the Power key (hold 2 seconds).
If your remote doesn’t match any of the options described, check its model – it’s listed on the back (e.g. RMT-2023-1). For rare modifications (e.g., remotes for Xiaomi Transparent TV), the Mute button can be hidden under the swipe down the touchpad.
Important! On Xiaomi's latest consoles (2023-2026), the Mute button is often physically missing, not a marriage, as the manufacturer intended to simplify the design, using gestures or keyboard combinations instead.
2. Alternative ways to turn off sound without the Mute button
If the Mute button is not on the remote or it does not work, use one of these methods:
- Double tap on Volume – On the Mi TV A2, P1 and Q2 models, press Volume quickly – twice in a row – the sound will turn off. Repeat the action to return the volume.
- Say, “OK Google, turn off the TV” (if Google Assistant is connected) or “For XiaoAI on Chinese firmware.”
- App Mi Home Open the app, select your TV and tap the speaker icon in the top right corner.
- On the back or side of the TV, find the Volume/Source button (usually under the Mi logo). Hold it for 3 seconds to turn the sound on/off.
On some firmware (such as PatchWall for the Indian market), the Mute function is available through quick settings: press Menu → Settings → Sound → Mute.
- Rebooted the TV (took the plug out of the socket for 30 seconds)
Checked the batteries in the remote (replaced with new ones)
Updated the TV firmware to the latest version

3.Why the Mute button doesn't work: typical problems
If the Mute button doesn't respond to a press, the reasons can be both hardware and software.
| Problem. | Possible cause | Decision |
|---|---|---|
| No push button. | Contamination of contacts or mechanical failure | Read the remote with alcohol, if it does not help - replace |

4. How to reassign the Mute button to other functions
In Xiaomi TV firmware based on Android TV (such as Mi TV 5 Pro or Q1E), you can reassign the action of the Mute button through the developer settings or third-party applications.
- Activate Developer Mode: Settings → About TV → Software Version → Press 7 times in a row
- Return to Settings → Additional → For developers and enable USB debugging.
- Install the Button Mapper app from Google Play (requires an Air Mouse remote or a connected keyboard).
- In Button Mapper, select Keycode 164 (this is the Mute button code) and assign a new action (such as launching Netflix or opening the control panel).
Warning: Reassigning system buttons can lead to firmware conflicts, such as Button Mapper settings resetting after software updates and the Mute button will stop working altogether, and we recommend backing up the settings before experimenting.
💡
If you often use Mute to temporarily shut down audio (such as during advertising), set it to quickly turn on subtitles. To do this, select the Toggle Captions action in Button Mapper, so you will see the text while the sound is turned off.
5. Sound control via smartphone: Mi Home and Google Home
If the remote is lost or broken, you can control the sound on Xiaomi TV from your smartphone.
- 📱 Mi Home (for all Xiaomi models): Connect the TV to the app (if not already done). Open the device card and tap the speaker icon. Use the volume slider or Mute button in the upper right corner to turn off the sound.
