Modern Smart TVs from Xiaomi, running on the operating system Android TV or Google TV, are powerful multimedia centers, but their functionality in terms of audio input is often limited by the built-in microphone of the remote or lack thereof. Users often face the need to connect an external microphone for karaoke parties, voice control without a remote or even for streaming gameplay.
Unlike computers, where microphone connectivity is decided by choosing a device in the sound control panel, the Android ecosystem is a big part of the world. TV It has its own peripheral nuances, and it can ignore some of the things that are happening. USB-Headsets or require special permissions for applications that use voice input. In this article, we will take a detailed look at all the available ways of connecting, from wireless Bluetooth solutions to wired ones. USB-adapters, and also discuss the software settings necessary for stable operation.
It is worth noting that there is no one-size-fits-all method for all models, as hardware compatibility plays a key role. TV may not serve food USB-port is off or have current restrictions, which is critical for the operation of active microphones. Therefore, before buying equipment, it is important to study the specifications of your particular device and the version of the installed firmware.
Types of microphones and their compatibility with Android TV
The first step to successfully integrating external hardware is to understand what types of microphones can work with a television platform at all. The peripheral market is huge, but not every device is recognized by the TV operating system as a sound input device. The main division is by type of connection interface: wired USB, wireless Bluetooth and specialized karaoke systems.
The most common and often supported option is USB-microphone USB Audio Class 1.0 or 2.0: Android System TV It has built-in drivers for basic standards, which allows you to connect many computer headsets and voice recorders directly, but complex multi-channel devices or microphones that require you to install specific drivers on Windows are likely not to work on the TV.
The second popular option is Bluetooth headsets. Xiaomi TVs are equipped with a Bluetooth module that allows you to connect not only headphones for output, but also headsets for input. Here it is important to distinguish between profiles: for voice transmission, you need an HSP (Headset Profile) or HFP (Hands-Free Profile), while the A2DP profile is responsible only for high-quality stereo sound and is not suitable for a microphone.
⚠️ Note: Not all Bluetooth headsets correctly transmit the microphone to TVs. Often the system sees the device, connects to it, but uses the built-in microphone TV or remote to input the sound, ignoring the external headset.
Specialized karaoke microphones, which are often wireless systems with separate USB-This device is usually a standard device. USB-Sound card, which provides high compatibility with Xiaomi TV. They are the preferred choice if your primary goal is singing, as they often have built-in sound processing and less latency.
Connection USB-microphone through a direct interface
The easiest and most reliable way to connect a microphone to a Xiaomi TV is to use it. USB-This method provides minimal signal delay and does not require complex pairing procedures, USB-hub, if the port on the TV is occupied or located in a hard-to-reach place.
The connection process starts with the physical connection of the devices. USB-microphone in any free port USB 2.0 or 3.0 on the back or side of the TV, the system should emit a characteristic sound of the device connection, and a pop-up notification of new equipment may appear on the screen. If this does not happen, check if the port is powered (usually the indicator on the microphone lights up).
After you're physically connected, check your device recognition on the system. Go to the TV settings menu. The path may vary slightly depending on the version of the PatchWall shell or Android TV, but it usually looks like this: Settings → Device → Preferences → Sound or Settings → Accessories.
☑️ Verification USB-connection
In the audio settings section, find the input device or microphone. If the system recognizes the device, it will appear in the list of available audio sources. In some cases, you may need to manually select an external microphone instead of the built-in one. If the device is not detected, try using another device. USB-port, preferably one marked as USB 2.0, as they often have better peripheral compatibility.
💡
If the microphone requires more power than a single port can provide, use the device. USB-Hub with own power or connect the hub to the network, and the TV to the hub.
Setting up a Bluetooth microphone and headsets
Using wireless devices eliminates unnecessary wires, but requires the right pairing setup. Xiaomi TVs allow you to connect Bluetooth headsets, but the process may be different from connecting to a smartphone. First of all, put your microphone or headset in pairing mode (usually by pressing the on button for a long time before the indicator flashes).
On the remote, click the settings button or go to the main menu and select Settings → Remotes and Accessories → Add Accessory. The TV will start scanning available devices within range. Once your microphone name appears in the list, select it to connect.
After successful pairing, the system may request confirmation of the device’s use to input audio. It is important to make sure that the audio input option is activated in the profile of the connected device. In some versions of Android TV, this is regulated in the Settings menu → Special Features → Hearing aids or similar sections where you can prioritize the Bluetooth headset.
| Parameter | Description | Recommendation |
|---|---|---|
| Latency (Latency) | Time between the word and its processing | Critical for karaoke, preferably <100ms |
| Bluetooth codec | Algorithm of compression and sound transmission | SBC or aptX Low Latency are preferred |
| Radio of action | Distance of stable communication | No more than 5-7 meters without obstacles |
| Autoconnection | Automatic start when switched on | Enable in accessory settings |
Note that Bluetooth microphones can cause noticeable delay, making them less suitable for professional karaoke, but also more suitable for voice control or video calls. If you notice a lack of synchronization, try shortening the distance between the TV and the microphone or removing interference sources such as Wi-Fi routers or microwave ovens.
What if the TV doesn’t see a Bluetooth microphone?
Use of the USB-adapters and sound cards
If direct microphone connection is impossible or the sound quality does not suit you, an excellent solution is to use external microphones. USB-It's a little device that connects to a sound card. USB-The port of Xiaomi TV and provides standard 3.5mm jack connectors for microphone and headphones. It is a versatile solution that works with any analog microphone.
The advantage of this approach is that the TV sees the sound card as standard. USB-So, you don't have to worry about the compatibility of the drivers of a particular microphone, the sound card supports the class. UAC (USB Audio Class, it will earn plug-and-play.This is especially true for studio capacitor microphones, which may require phantom power (although simple power is available). USB-It is not usually given to cards, for dynamic microphones it is not a problem).
When choosing an adapter, consider having your own DAC/ADC (Digital Analog Converter) chips built into cheap adapters can add noise or have a low sampling rate. For karaoke and streaming, choose models with claimed support for 16-bit/48kHz or higher. Connect to a USB port, then select the name of your sound card as the output and input device in the TV audio settings.
⚠️ Attention: When in use USB-sound cards with a microphone input of 3.5 mm make sure you use a headset plug (TRRS) Or an adapter if your microphone has a separate plug, and the standard input on the adapter may not see the signal from a simple microphone cable.
Software configuration and applications for working with the microphone
Connecting equipment is only half the battle, and in order for the microphone to function, you need an app that captures and processes sound, and depending on your goals (karaoke, streaming, voice input), the software you need will vary.
For karaoke on Xiaomi TV, there are many apps from the Google Play store or the built-in PatchWall store. Popular options include Star Karaoke, TuneIn Radio (for some features), or specialized applications from microphone manufacturers. Once you install the application, you need to go to its settings and select the external device connected to it in the Audio Input or Microphone section.
If you plan to use the microphone for streaming or video calls (e.g. via Zoom or Skype on TV), make sure the app is given the appropriate permissions. Go to Settings → Apps → [Your App] → Permissions and activate access to the microphone. Without this step, the app will show an error or use an incorrect sound source.
💡
The key is to set up a specific application: even if the microphone is running on the system, the application can default to using the built-in sensor, so manual selection of the sound source in the software settings is mandatory.
For advanced users who want to use the TV as part of a stream-Setup, you may need to install audio processing applications such as Lesser AudioSwitch (requires installation via APK, as it is often absent from the official store), which allows you to force switch sources of input and output, which is necessary if the standard Android TV system stubbornly ignores the external microphone.
Solution: microphone is not working or quiet sound
Even with the right connection, users often run into problems: the microphone is not working, the sound is too quiet or there is a strong echo. One of the most common reasons is insufficient signal amplification. Unlike a PC, Android TV often does not have a Microphone Boost slider in the standard interface.
If the sound is quiet, try using an external sound card with its own volume control or a microphone with a built-in amplifier. Also check if the noise cancellation function is activated in the settings of the TV or application, which can mistakenly cut off useful voice frequencies, making speech indistinct.
The problem with echoes usually occurs when the sound from the TV speakers hits the microphone. For karaoke, this is partly normal, but for video calls, it's critical. Solution: use the headphones to output the sound, leaving the microphone active for input. This will break the acoustic loop. If the headphones are not in use, turn down the volume of the TV or change the microphone position so that it is directed away from the speakers.
