When your Xiaomi smart TV stops responding to commands with its voice, it often takes you by surprise: You press the microphone button on the remote, but instead of the expected search or opening of the application, the system is silent or gives a connection error, which can be due to both a software failure of the Android TV operating system and a banal discharge of batteries in the remote control.
In most cases, the problem lies in the connection between the remote and the TV, because voice commands are transmitted over Bluetooth protocol, not through an infrared port. If a conventional brute force of channels works and a search does not, then the infrared module is good, but the Bluetooth connection is broken or is not working correctly. In this article, we will discuss all possible causes of the malfunction in detail and offer step-by-step instructions for their elimination.
Before you take your device to a service center or buy a new remote, you should try to solve the problem with software methods. Often, it is enough to simply reconnect the device or clean the cache of system services to restore the full functionality of the Google Assistant on your TV.
The main reasons for the failure of the microphone
The first thing to understand is the nature of the bug. Voice input on Xiaomi Mi TV and Redmi TV is a complex chain of interactions between the remote hardware, the Bluetooth module of the TV and Google servers. If even one link falls out, the function stops working. Most people find that the remote is simply not paired in Bluetooth mode, although the IR signal continues to flow.
Another common cause is software conflict: After a major firmware update, MIUI for TV, some system services may not work smoothly, and the microphone condition in the remote itself should be considered: moisture, dust, or mechanical shock can cause a sensitive element to fail. In rare cases, the problem lies in the privacy settings, where the microphone may be denied by default.
⚠️ Note: If your remote only supports IR communication (usually old or budget models without a microphone button), voice search through it is impossible. In this case, you will need to purchase the original Xiaomi Bluetooth Voice Remote remote or use the remote app on your smartphone.
It is important to distinguish between the types of remotes, because it depends on the method of diagnosis. Voice-enabled devices have built-in batteries or require high-quality batteries, since Bluetooth consumes more power than an IR emitter. Weak charge often leads to the remote running "over and over" or loses communication with the base immediately after the microphone is activated.
Diagnostics of Bluetooth remote connection
Since voice input relies on Bluetooth, the first step should be to check the connection status. Even if you can switch channels, it does not guarantee that the Bluetooth channel is active. Go to the settings of the TV and check the list of connected devices. The remote should be displayed there as an active input device.
It's often the remote that's "remembered" by the TV, but the connection is in sleep mode or has been frozen. Forced reconnection requires you to do the pairing again. This is the most effective way to solve 80 percent of voice control problems. Make sure that the distance between the remote and the TV is minimal during setup.
Follow the following steps to reconnect:
- 🔹 Press simultaneously and hold the Home (house icon) and Back (arrow) buttons for a period of time. 5-10 seconds.
- 🔹 On the TV screen should appear a message about finding a new device or a successful connection.
- 🔹 If the message doesn’t appear, try removing the batteries from the remote for 10 seconds, then inserting them back and repeating the procedure.
Some Xiaomi TVs with PatchWall or a pure Android TV may have different interfaces. If the standard combination doesn't work, check the instructions for your particular model. Sometimes you need to first remove the device from the Bluetooth list in the TV menu and then pair it.
☑️ Checking Bluetooth connection
Configure system parameters and permissions
Android TV has strict privacy policies: If access to the microphone has been accidentally blocked in the settings of the application or the system itself, voice search will cease to function, often after resetting settings or installing third-party launchers.
Check if the microphone restrictions are worth the cost for Google system services. Go to Settings → Apps → Show system processes. Go to Google or Google Play Services and check the permissions section. Make sure the Microphone slider is activated.
You should also pay attention to the input language. Voice search may not work if you have a language that is not supported by an assistant in your area, or if the keyboard layout is downed. Try changing the system language to English, checking the search work, and then returning the native language. This action often restarts the corresponding services.
⚠️ Warning: Do not install third-party voice control apps from unverified sources. They may conflict with the Google Assistant system, intercepting microphone control and causing disruptions to the staff remote.
Another important parameter is the date and time. If your TV has lost its time settings, Google's security certificates may stop working correctly, which blocks voice data from being transmitted to the server. Set up automatic time synchronization across the network in the Settings menu → Device → Date and time.
Problems with network connectivity and DNS
Voice search is not processed inside the TV, it's sent to Google's servers for recognition, so a stable Internet connection is critical. DNS-When you request or block certain ports, the team will not reach the destination.
Try to prescribe static settings in the TV network DNS-Often, providers default to slow or unstable DNS-servers, use of public DNS Google or Cloudflare can significantly improve system response.
To change the DNS, follow the following steps:
- Go to Settings. → Network and Internet.
- Select your connection (Wi-Fi or Ethernet) and click "Change" or "IP settings".
- Switch from DHCP to Static.
- In the DNS 1 and DNS 2 fields, enter the addresses 8.8.8.8 and 8.8.4.4.
Once you save your settings, be sure to restart your TV, and if the problem was ISP blocking requests or DNS crashes, voice search should work, and check if the router has parental controls that can block access to Google services.

Resetting settings and software updates
If software failures are system-specific, deeper intervention may be needed. The MIUI TV firmware update often includes Bluetooth stack bug fixes. Check for updates in the Settings menu → Device → System Update.
In case the update doesn’t help or the system is unstable after it, an effective method is to clean up the cache of Google services.This won’t delete your personal data or installed apps, but will reset temporary files that may have been corrupted.
The table below shows the main activities for system maintenance:
| Action. | Where to find out. | Risk of data loss |
|---|---|---|
| Cleaning up Google's cache | Settings → Applications | No. |
| Resetting network settings | Settings → Network | Wi-Fi passwords |
| Full reset (Factory Reset) | Settings → About the device → Reset | All data. |
| Update of the PO | Settings → About the device | No. |
A radical, but often the only way to work is to reset completely to factory settings. Before you do that, be sure to save your lists of important apps and passwords, as the TV will return to the "out of the box" state.

Use it. USB-It's a keyboard for settings after reset, and it's going to speed up the initial configuration of the TV, especially the Wi-Fi password.
Alternative methods of voice management
If the hardware remote is damaged and repair is impossible, don’t give up the convenience of voice control. Android TV ecosystem offers several alternative ways to enter commands that can work even more stable than the regular remote.
The most affordable option is to use a smartphone: the official Google Home or Android TV Remote Control app allows you to use your phone's microphone to control your TV. The phone and TV must be on the same Wi-Fi network, a solution that often helps when the remote is out of touch.
You can also connect. USB-A headset or a regular computer microphone if your Xiaomi TV model supports external audio devices. USB-port and driver support system, which is not implemented in all models.
⚠️ Note: When using third-party remote apps on your smartphone, make sure they have permission to access the microphone in the settings Android/iOS. Without this permission, the voice input button in the app will be inactive.
For advanced users, alternative launchers like FLauncher or ATV Launcher are available, which have their own built-in voice search modules, and can bypass the system limitations of the standard PatchWall shell if that’s where the problem lies.
💡
If the desktop is faulty, using your smartphone as a remote control over Wi-Fi is the fastest and freest temporary solution to access voice search.
