Modern Xiaomi TVs, running on the operating system Android TV or Google TV, often equipped with built-in acoustics, the quality of which may not satisfy demanding users. To create a full-fledged home theater owners often resort to buying external audio systems, and wireless connection becomes one of the most convenient solutions.
The process of pairing devices does not require deep technical knowledge, but it has its own nuances, depending on the firmware version and the TV model. Wireless audio transmission over Bluetooth protocol provides sufficient sound quality for watching movies and listening to music, although it is inferior to wired interfaces in bandwidth. In this article, we will discuss in detail an algorithm of actions that will allow you to quickly adjust the output of sound to external acoustics.
It is worth noting that the stability of the connection depends on the distance between the devices and the presence of interference in the air. Before setting up, make sure that your soundbar is healthy and is in standby mode. Proper equipment preparation is the key to successful synchronization without unnecessary reboots and resets.
Preparation of equipment for wireless connection
The first step before you start the pairing procedure is to properly prepare both devices: the Xiaomi Mi TV or Xiaomi TV Stick should be on and running the current version of the operating system. Check for updates in the settings menu, as older versions of Android TV may have bugs affecting the Bluetooth module.
Soundbar also requires pre-tuning. Most models need to be put into a special visibility mode for the TV to detect them, which usually requires clamping a certain combination of buttons on the remote or device body until the indicator flashes blue or red.
Make sure there are no massive metal objects or working microwave ovens between the TV and the acoustic system that can cause interference in the 2.4 GHz range. The optimal distance for the initial setup is no more than 1-2 meters. Once successfully connected, the range can be extended, but for the initial handshake it is better to be in close proximity.
⚠️ Warning: If the indicator on the soundbar flashes too quickly or changes color in an unusual way, it may already be trying to connect with another gadget from its history.
It is also important to check the battery charge in the remote control, if it is wireless, or make sure that the power from the network is stable. Unstable voltage can lead to interruptions in the operation of the Bluetooth module, which will complicate the search and connection process.
Step-by-step instructions for activating Bluetooth on Xiaomi TV
The interface of Xiaomi TVs may vary slightly depending on the regional version of the firmware (Global, EU, CN), but the logic of the device search remains the same. You need to get to the main menu of system settings. To do this, click the button with the image of the gear on the remote control or select the appropriate icon in the upper right corner of the screen.
In the menu that opens, find the connection and peripheral section. In the classic PatchWall shell or pure Android TV, this item is often called Devices and Accessories or Bluetooth, and this is where all the wireless interfaces of the TV are managed.
Once you go to the desired partition, you need to activate the wireless module itself if it is turned off. The system will automatically start scanning the surrounding space for available gadgets. If the list is empty, click Add Device or Search to initiate a forced scan.
☑️ Device search algorithm
In the search process, the TV can display not only the name of the soundbar model, but also its name. MAC-Be careful when choosing, especially if other Bluetooth devices of your neighbors or your own gadgets, such as headphones or smartphones, are in sight.
The pairing process and the selection of the output device
When your soundbar name appears on the list of available devices (e.g. Samsung) HW-Q60T or JBL Bar 5.1), select it with the remote and press the button «OK» Or "Enter." You may see a request on the TV for a pairing confirmation or input. PIN-In most modern systems, the code is either not required or is standard (0000 or 1234), which is usually displayed on the screen.
Once confirmed, the TV will display a successful connection notification, the audio should automatically switch from the TV speakers to external acoustics, if this does not happen, you must manually change the audio output settings in the corresponding menu, sometimes the system suggests selecting a usage profile: "Music", "Film" or "Games", which affects the priorities of signal processing.
In some cases, the TV may request permission to access contacts or call logs, even if the device is only used for sound.To improve security and data privacy, it is recommended to reject such requests, since the soundbar does not need access to personal information to play audio.
| Status of indicator | Meaning | User action |
|---|---|---|
| Slow blinking | Standby/search mode | Run a search on TV. |
| Fast blinking. | The mode of pairing (Pairing) | Select the device in the list |
| It's burning all the time. | Successful connection | Check for sound. |
| Blinks red. | Error or low charge | Check the power and distance |
If the connection is successful but the sound is not available, check the volume level on the soundbar itself. Often, after switching on, the external acoustics have a minimum volume level, and the sound seems to be missing, although in fact it is played very quietly.
Configuring sound and codec parameters
After successful pairing, it is important to pay attention to the audio format settings. Xiaomi TVs support various codecs such as SBC, AAC, aptX and sometimes LDAC. The quality of playback depends on which codec will be selected to transmit the signal between the TV and the soundbar.
To access advanced settings, go to the Sound section of the main settings menu. Here you can find the Digital Output or Sound Format. For Bluetooth devices, the best choice is often AAC or aptX if both devices support these standards. SBC is the basic codec and provides compatibility, but can give less detail to the sound.
What is Latency (Sound Delay)?
The sound effects menu can also disable built-in TV audio enhancements such as virtual surround sound or equalizer to avoid dual signal processing, especially if your soundbar has its own processing algorithms that may conflict with MIUI TV software filters.
Some users prefer to use Auto mode in the output format settings, in which case the TV itself tries to determine the best format supported by the connected device, however, if you encounter distortion or cracking, it is better to manually fix the specific codec.
Solving Typical Problems and Dissynchronization
One of the most common problems with wireless acoustics is the audio and video sequence dissynchronization. Sound can lag behind the picture, which is especially annoying when watching dialogue in movies. To solve this problem, audio settings often include the "Audio Delay Correction" option, which allows you to artificially delay the video sequence or speed up the audio stream.
If the connection is constantly interrupted or the sound becomes intermittent, try to reduce the distance between the TV and the soundbar. It is also worth checking whether the air is congested with other devices. A Wi-Fi router running at 2.4 GHz can cause serious interference with the Bluetooth connection.
⚠️ Attention: Use USB-2.4GHz Wi-Fi adapters, plugged directly into the port next to a Bluetooth antenna TV, often cause unstable sound performance. Use a Wi-Fi extender for the adapter or switch the router to 5GHz.
If the TV doesn't see the soundbar after several attempts, reboot both devices completely. Pull the power cords out of the socket for 10-15 seconds to reset the residual charge and clear the cache of the communication modules.
💡
If audio desynchronization is only seen in one particular app (like YouTube or Netflix), the problem may be on the app side.Try clearing that app's cache in the Android TV settings.
It is also worth considering that some older soundbar models may not work properly with new versions of Android TV. In such cases, the only solution is to use an optical cable (S/PDIF) or HDMI ARC, if this is possible.
Features of using different soundbar models
Different speakers implement the Bluetooth protocol differently. Samsung soundbars, for example, often require the use of the SmartThings app for initial setup, after which they can operate in Bluetooth receiver mode independently of the smartphone. Sony and JBL devices are usually more versatile and connect like standard audio headsets.
Multi-channel systems (5.1, 7.1) via Bluetooth are most often stereo (2.0) because standard Bluetooth bandwidth is not enough to transmit uncompressed multi-channel sound. Full surround sound via Bluetooth requires specific codecs and support from both devices, which is rare.
When connecting subwoofer soundbars, make sure that the subwoofer itself is also connected to the main panel (usually automatically via radio). Sometimes when switching the signal source on the TV, the subwoofer may go into standby mode, and it will require a short-term increase in volume to activate it.
💡
Bluetooth is a convenient solution for music and casual TV viewing, but for a home theater with surround sound, it is preferable to use an HDMI ARC or optical cable to avoid audio compression.
Some advanced models allow you to connect two Bluetooth devices at once, creating a stereo pair or multiroom system. However, Xiaomi TVs normally support audio output to only one Bluetooth device at a time, unless you use third-party launchers or modifications.
