The integration of an audio system from one manufacturer with another brand’s TV panel often raises questions among users seeking to improve sound quality. The combination of Samsung and Xiaomi is popular because it allows the Korean company’s advanced sound technology to be combined with the Chinese giant’s affordable and functional screens. The right connection of devices provides access to surround sound and high frequencies that built-in TV speakers cannot provide.
Modern interfaces allow you to organize the transmission of audio stream in several ways, each of which has its own technical features. The choice of method depends on the available connectors on the back of your Mi TV or Redmi TV, as well as on the model of the Samsung home theater used. In this article, we will discuss all possible switching options in detail so that you can choose the most suitable for your situation.
Before you start physical manipulation, make sure that both devices are turned off or in standby mode.This basic electrical safety rule helps avoid power surges and potential port damage. Carefully inspect the rear panels of equipment to identify the types of connectors available.
Preparation of equipment and choice of interface
The first step in the setup process is to identify the ports that are present on your hardware. Xiaomi TVs usually come with a full suite of modern interfaces, including ARC/eARC-enabled HDMI, optical output and headphone jack. Samsung home theaters also offer a wide range of connectivity options, but configurations can vary depending on the model's year of release.
The most preferred option is always to use digital interfaces such as HDMI. These provide high-resolution uncompressed audio and allow volume control from the TV remote thanks to the CEC function. If your soundbar or receiver supports the HDMI eARC standard, this guarantees the best sound quality for Dolby Atmos and DTS:X formats.
In the event of absence HDMI-The optical connection should be considered in the port on the old model of the audio system. The digital optical cable (Toslink) transmits sound without loss of quality, although it does not support some of the latest audio formats (RCA 3.5 mm) should be used only as a last resort when other options are physically impossible.
⚠️ Warning: Make sure you use a serviceable cable.A damaged conductor can cause cracking, interruption of the signal or complete absence of sound even with the right settings.
💡
Use cables no longer than 3-5 meters long for HDMI and optical connections to avoid signal attenuation and loss of data quality.
Connection via HDMI ARC/eARC
The HDMI ARC (Audio Return Channel) interface is the gold standard for modern acoustics, allowing audio from the TV to the external system to be transmitted via the same cable that transmits video, making it much easier to install and less wired. To implement this feature, Xiaomi needs to find a port with the appropriate labeling.
The connection process starts with the HDMI cable connecting the devices. One end of the cable is inserted into the HDMI OUT port (TV-ARC) on the back of the Samsung home theater. The second end connects to the HDMI port (ARC) on the Xiaomi TV. This is usually the second or third port, but the exact location is better specified in the instructions for a specific TV model.
After the physical connection, activate the function in the program menu. On Mi TVs, go to the audio settings section and select the external output. The system automatically recognizes the connected device. If this does not happen, check if the CEC control option is enabled in the system settings.
- 🔌 HDMI ARC: Standard audio return channel, supports compressed multichannel formats.
- 🔊 HDMI eARC: Improved high-bandwidth version for object sound.
- 🎮 CEC: Protocol to control soundbar volume with TV remote.
- 📺 One Remote: Samsung's feature that could conflict with Xiaomi management requires customization.
☑️ Connection check HDMI ARC
Use of Optical Cable (Toslink)
The optical interface remains relevant for users whose hardware does not support HDMI ARC or has compatibility restrictions. The light signal transmitted over the fiber is completely protected from electromagnetic hoops, which guarantees the purity of the sound. The connector is characteristically shaped and often closed with a plastic plug that must be removed before connecting.
Use a Toslink cable to connect. Push one end into the Digital Audio Out (Optical) port on a Xiaomi TV and the other into the Digital In port on Samsung's soundbar. The cable should enter before the characteristic click, but don't put too much effort into it to avoid damaging the brittle fiber inside.
In the settings of the Android TV or PatchWall, you need to manually change the format of the output. The default system may try to output the signal through the built-in speakers or HDMI. Find the item "Digital output" and set the value "Auto" or "PCM" if you have problems with decoding.
| Parameter | HDMI ARC | Optical (Toslink) | Bluetooth |
|---|---|---|---|
| Sound quality | High (Lossless) | High (Compressed) | Medium (Compressed) |
| Control of the remote | Complete (CEC) | Only on/off | Limited. |
| Support for formats | Dolby Atmos, DTS:X | Dolby Digital, PCM | SBC, AAC, aptX |
| Stability | Maximum | Tall. | Depends on the interference. |
Why isn't there a sound on the optics?
Wireless Bluetooth connection
Bluetooth wireless technology is convenient for organizing space without unnecessary wires, although it is inferior in data transfer to wired analogues. This method is suitable for Samsung soundbar models equipped with an integrated Bluetooth module, and any Xiaomi TV based on Android TV. Latency when watching video can be noticeable, but modern codecs minimize this effect.
To pair, turn on pairing mode at home theater. This usually requires pressing and holding the Bluetooth or Pairing button on the remote or device body before the indicator flashes. On Xiaomi TV, go to Settings menu → Remotes and accessories → Add accessory.
The system will start searching for available devices. Once your soundbar name appears on the list (e.g., HW-Q60T), select it to connect to. Once successfully paired, the TV will automatically switch the audio output to the external system when turned on.
⚠️ Note: When using Bluetooth, volume control may not work properly due to differences in protocol implementation by different manufacturers.
Customization of sound parameters on Xiaomi TV
Once physically connected, it is critical to properly configure the software part.The PatchWall operating system or pure Android TV on Xiaomi TVs has flexible audio settings. Go to Settings → Sound to access the basic settings.
In Digital format, select Auto or Passthrough, which will allow the TV to transmit the original bit stream to a Samsung soundbar decoder that can handle better than the TV's built-in tools. If you hear distortions, try switching to PCM, but this will limit the sound of stereo.
It's also worth turning off the TV's built-in speakers if the system doesn't switch automatically. In some firmware, this is done by choosing "Audio System" instead of "Dynamics TV." Be sure to check the equalizer settings and turn off extra effects such as "Volume Sound" if they duplicate the soundbar features.
💡
The right setup of the digital format (Passthrough) is more important than the choice of connection type, as it determines whether the soundbar will be able to reach its potential.
Addressing common problems
Even if you follow all the instructions, you can have technical difficulties. Often users experience no sound or periodic loss of sound. First of all, check if the soundbar is in Mute or Silent mode. Also make sure that the TV does not have a minimum volume set that blocks the external output.
Problems with synchronizing audio and video (lip synchronization) are solved through delay settings. In the Xiaomi TV's audio menu, find "Sound Lag" or "A/V Sync" and move the slider until the lip movement matches the voice. Samsung soundbars can also have their own delay setting in the menu.
If the device is not detected by the system, perform a full reboot cycle, pull the power cords of both devices from the socket for 30 seconds, then turn on the soundbar first, then turn on the TV, which will clear the error cache and force the system to re-interview the ports.
