Xiaomi Redmi TV Soundbar connection: full guide

Modern TVs, including popular Xiaomi Mi TVs and Redmi Smart TVs, often feature thin packages that inevitably affect the quality of the built-in sound. To compensate for the lack of powerful speakers and get a truly cinematic sound, users acquire external acoustic systems. The subwoofer and the main soundbar module can radically change the perception of movies and games, adding depth to low frequencies and clarity to dialogue.

However, after buying a device, many owners are faced with the question of how to integrate it into the home entertainment network. The process of connecting Xiaomi Redmi TV Soundbar may seem difficult only at first glance, but in fact it requires only a careful study of the ports on the back of the TV. The right choice of data interface directly affects the final audio quality, so it is important not just to plug in the cable, but to choose the best method for your particular TV model.

In this article, we will take a look at all the switching options available, from wired high-speed connections to wireless protocols. You will learn how to configure the output of sound in the Android TV system, how to activate volume control from the TV remote and what to do if the sound does not appear immediately. Proper initialization of equipment will avoid most typical errors and enjoy surround sound without unnecessary delay.

Choosing the optimal connection interface

The first step before starting a physical connection is to review the available ports on your TV and the speaker system itself. Xiaomi Redmi TV Soundbar usually offers a wide range of interfaces, including HDMI, optical output and Bluetooth, but not all of them can be equivalent in signal quality. Choosing the right cable is the foundation for the stable operation of the entire multimedia system in your home.

The most modern and preferred option is to use the protocol. HDMI ARC (Audio Return Channel, which allows you to transmit high-resolution multichannel audio without compression, and also allows you to control the soundbar volume with a standard remote control. HDMI-The ports will be marked with the appropriate abbreviation, and it is it that should be used in the first place.

In cases where HDMI is not possible due to port occupancy or compatibility with older technology, you can use the optical cable Toslink. It also provides lossless digital audio transmission, supporting formats like Dolby Digital, although it does not allow you to control the soundbar from the TV remote as flexibly as HDMI. For wireless connection, Bluetooth module is convenient without wires, but can introduce a small audio delay.

It is important to consider that some older TV models may not support both-way HDMI transmission, which will require additional adapters or a change in connectivity strategy. Always pay attention to the inscriptions next to the sockets on the back so as not to connect the cable to the port, designed only for video input.

Connection via HDMI ARC: maximum quality

The HDMI ARC interface is the gold standard for connecting modern acoustics to a TV, it allows for uncompressed multichannel audio and, critically, provides a CEC (Consumer Electronics Control) feature that synchronizes the remote and soundbar. To get started, you'll need an HDMI cable that supports 1.4 or higher, preferably labeled "High Speed."

The installation process begins by searching the back of the TV for a connector signed as HDMI (ARC) or simply ARC. Insert one end of the cable into that port and the other into the corresponding socket on the Xiaomi soundbar. After the physical connection, you need to turn on both devices so that the system can automatically identify the new periphery and switch the audio output.

Customization of the software part often happens automatically, but some versions of the MIUI for TV firmware require manual intervention. Go to the settings menu, select the Sound section and set the value of "HDMI ARC" or "Auto" in the "General settings" section. Also make sure that the HDMI-CEC function is activated in the "General settings" section, which can be called differently depending on the matrix manufacturer (for example, SimpLink or Anynet+).

⚠️ Note: If you have connected the cable HDMI If you've lost a picture or you've got an error message, try replacing the cable with a better one. Cheap cables may not be able to handle the bandwidth required to transmit video and audio simultaneously.

The advantage of this method is the ability to transmit the most advanced audio formats, such as Dolby Atmos (supported by content and hardware).In addition, when you turn off the TV, the soundbar will also go into standby mode, which saves electricity and eliminates the need to use two remotes to control the volume.

Use of optical cable Toslink

The S/PDIF optical interface (often labeled Optical or Toslink) remains one of the most reliable ways to transmit digital sound, using pulses of light to transmit data, which completely eliminates the possibility of electromagnetic inputs, which can manifest as background or hissing in the acoustic system.

To connect, look at the back of your TV for the Digital Audio Out (Optical) port. Remove the protective caps from both ends of the optical cable and insert them until the characteristic click. It is important not to bend the cable at a sharp angle, as there is a fragile fiberglass inside, damage to which will cause you to lose your signal. On the soundbar, select Optical mode if the switching does not happen automatically.

In the settings of the Xiaomi TV, you need to force the format of the output. Go to Settings → Sound → Digital output and select the option “Optical” or “S/PDIF”. Here you should pay attention to the coding format: for maximum compatible quality, choose PCM for stereo or Pass-through for surround sound, if the soundbar can decode it yourself.

The main limitation of optical cable is the inability to transmit the latest object-oriented audio formats, such as Dolby TrueHD or DTS-HD Master Audio. However, for most streaming services and cable TV, the bandwidth of Toslink is quite enough to produce high-quality 5.1 surround sound.

Wireless connection via Bluetooth

Bluetooth technology offers maximum freedom of placement and no extra wires, which is especially true for interiors where every cable is in sight.The Xiaomi Redmi TV Soundbar features a Bluetooth module that makes it easy to pair it with a TV if both devices support this protocol.This is ideal for temporary connection or if all the wired ports are already busy.

To pair, turn on the soundbar and activate the device search mode. Usually, you need to press and hold the Bluetooth button on the remote or the case before the indicator flashes. On the TV, go to the Settings menu → Remotes and accessories → Device search or a similar section depending on the version of Android TV. When the name of your soundbar appears in the list, select it to connect.

Note that when transmitting over Bluetooth, the audio signal is compressed to save traffic, which can slightly reduce the detail of high frequencies compared to wired methods. In addition, the range is limited, and the presence of obstacles between the TV and the soundbar can cause interruptions. For stable operation, the distance between devices should not exceed 5-7 meters.

Despite the limitations, Bluetooth remains a convenient way to quickly connect your smartphone or tablet to a soundbar to listen to music without the TV. Simply switch the soundbar source to BT mode and search from your mobile device, the quality of the transmission in this case will depend on the codec used (AAC, aptX or SBC).

Customization of sound in the Android TV system

After physical connection, you need to configure the software part correctly so that the Xiaomi or Redmi TV transmits sound to external acoustics, not to built-in speakers. In the Android TV operating system, a special section in the main settings menu, which takes priority over automatic device definition, is responsible for this.

Open the settings menu and go to the Sound section (or Display & Sound in English). Find Dynamics or Audio Drive. Here you will be asked to choose the source: TV Dynamics or Audio System. Choose the second option to activate the external output. If you use HDMI ARC, the system can suggest switching by confirming the action.

For advanced users, there is an engineer mode or advanced sound settings available where you can adjust the equalizer and balance. However, for basic work Redmi TV Soundbar just set the output format to Auto or HDMI. If the sound wheezes or interrupts, try changing the sampling frequency in additional settings or switching the mode from Volume Sound to Stereo for verification.

💡

If the sound is only played through the TV's built-in speakers, even when the external output is selected, try to completely turn the TV off the socket for 1 minute. HDMI-handshakes and will force the system to re-interview connected devices.

Don’t forget to regularly update your TV software through the Settings menu → About TV → System Update. Manufacturers often release patches that improve compatibility with external audio systems and fix HDMI-CEC protocol bugs, which directly affects the soundbar’s work tab.

Diagnostics and solution

Even with the right connection, there can be situations where the sound is missing or not working correctly. One of the common problems is that there is no signal when using adapters or old cables. In this case, the system can assume that the external device is not connected, and continue to output the sound to the built-in speakers. Check the density of the contacts and try to stick the cable.

If the soundbar is on but no sound, check the audio format settings. Some TV models default to try to output sound in a format that the soundbar cannot decode (e.g. DTS on a device without DTS support), in which case you need to manually switch the output format in the TV settings to PCM, which is the universal standard.

⚠️ Attention: When using an optical cable, make sure that protective plastic plugs are removed from the ends of the connector. Often users insert a cable with plugs, thinking that the connection is there, although the light signal does not physically pass through.

In case of problems with volume control from the TV remote, make sure that the CEC function is activated not only in the TV, but also supported by the soundbar itself in the current mode of operation. Sometimes it helps to reconnect the HDMI cable with the devices on (although this is not recommended often), which causes the controller to shake hands again.

💡

90% of audio problems are solved by choosing the right Audio output in the TV settings and replacing the HDMI cable with a certified version of High Speed.
