How to connect the soundbar to a Xiaomi TV: the complete guide

Xiaomi’s modern slim TVs are famous for their design and image quality, but physics dictates its laws: there’s simply no room for powerful speakers in a slim case. Built-in speakers often produce a flat sound devoid of depth and bass, which is especially noticeable when watching blockbusters or listening to music. That’s why connecting an external acoustic system like a soundbar becomes not just a whim, but a necessity for those who want a full theatrical experience at home.

Owners of Xiaomi Mi TV and Redmi TV devices running on Android TV or PatchWall have several options for integrating external sound. You can use wired connections for maximum quality or wireless technologies to preserve the aesthetics of the interior. The choice of the specific method depends on the model of your TV, the version of the operating system and the technical capabilities of the acoustic system itself.

In this article, we will take a look at all the connectivity options available, from classic HDMI ARC to modern Bluetooth protocols, and discuss the nuances of settings, possible remote conflicts, and ways to solve typical audio problems so you can enjoy clean and powerful audio without unnecessary technical complications.

Choosing the optimal connection interface

Before you grab the cables, you need to audit the available ports on the back or side of your Xiaomi TV. The brand range is diverse, from budget Redmi to flagship Mi TV QLED, and the set of interfaces can vary significantly. Understanding the available options will allow you to choose the method that will ensure the best sound quality and ease of management.

The most preferred option for modern systems is to use the HDMI ARC port or its newer version of eARC. This technology allows you to transmit not only high-quality multi-channel sound, but also control the soundbar volume using a remote control. If your soundbar supports HDMI, this is definitely the best choice for most use cases.

In situations where HDMI is busy or the audio device does not support this interface, Optical (Toslink) comes to the rescue, providing lossless digital audio, supporting formats like Dolby Digital, although inferior to HDMI in bandwidth for the latest audio codecs. Analog output 3.5 mm AUX should only be considered as a last resort, since it gives the least quality sound.

• 🔌 HDMI ARC/eARC: Best sound quality, support for all modern codecs and control of one remote control.
• 🔦 Optical cable (S/PDIF): Stable digital transmission, no electromagnetic tips, but no volume control from TV.
• 🎧 Bluetooth: No wires at all, but latency and less compression.
• 📺 Analog (3.5mm): Universality, but low sound quality and lack of surround sound support.

⚠️ Note: Not all ports HDMI Xiaomi TVs support the function ARC. This port is usually marked with a special inscription (ARC) Or (eARC) Connecting the soundbar to a normal port HDMI will allow you to display the image (if the soundbar has a through passage of the video), but the sound through it will not go without the use of additional cable.

For HDMI, it is recommended to use either 2.0 or 2.1 cables, especially if you plan to use eARC functions for formats like Dolby Atmos. Cheap cables may not be able to transmit data over long distances, which will lead to interruptions or no signal at all.

Connection via HDMI ARC and eARC

The HDMI ARC (Audio Return Channel) interface has become the gold standard for home theaters. It lets you transmit audio from TV to soundbar over the same cable that transmits video, but in the opposite direction. For Xiaomi owners, this means that once set up correctly, you won't need a second remote to control volume.

The connection process starts with the physical connection of the devices. You need to find an HDMI port marked ARC on your TV and the corresponding HDMI OUT port (ARC) on the soundbar. Once connected by cable, the system must automatically recognize the new device, but full operation often requires activation of the HDMI-CEC protocol in the settings of the TV.

On Xiaomi TVs with PatchWall shell or pure Android TV, the path to settings can look different. Usually you need to go to Settings, then select General or Device, and find HDMI-CEC. In some models, this feature may be called Mi Link or just CEC. Its activation is critical for synchronizing control.

If the audio doesn't appear automatically after you've connected, check the audio output settings. Go to Settings → Sound → Output and force HDMI ARC or External Speakers to select. Also make sure the audio format is set to Auto or PCM mode if the soundbar doesn't decode complex formats on its own.

💡

If the soundbar does not turn on automatically when you turn on the TV, check whether the “Switch Off” or “Sync Power” function is enabled in the HDMI-CEC settings of the soundbar itself.

Use of Optical Cable (S/PDIF)

The optical interface remains one of the most reliable ways to transmit sound, especially for previous generations of technology or in conditions of severe electromagnetic interference. Toslink cable transmits a signal using light, which completely eliminates the possibility of the occurrence of tips, which can manifest as background or cod in acoustics.

To connect, you'll need a cable with square connectors protected by plastic plugs. Before inserting the plug port, you need to remove. The connectors on Xiaomi TVs and soundbars usually have backlights that light up red when connected properly and powered. If there's no glow, check the cable's landing density to the characteristic click.

The main feature of this method is the lack of control signals. Xiaomi TV will consider optical output just a way of transmitting data stream, but will not be able to adjust the volume of the soundbar or turn it on / off with you. You will have to use two remotes: one for navigating the TV menu, the other for adjusting the volume.

In the TV audio settings, you need to manually switch audio output to Optical output or S/PDIF. It is also important to adjust the output format. If your soundbar supports Dolby Digital decoding, select this mode. If you only hear hissing or static noise, switch the format to PCM, as some simple soundbars do not understand the coded streams.

⚠️ Warning: Optical cable has a plastic core that can break when bent sharply.Do not bend the cable at less than 90 degrees or tighten it too tightly with screeds so as not to damage the fiber's internal structure.

Despite the lack of volume control from the TV remote, the optical connection is often chosen by audiophiles for its stability. Unlike Bluetooth, it completely eliminates signal compression and delay, making this method ideal for viewing content where synchronization of lips and sound is important.

Wireless connection via Bluetooth

Wireless is a choice for minimalism and no extra wires in the interior. Xiaomi Android TVs are equipped with a built-in Bluetooth module, which makes it easy to pair them with wireless soundbars and headphones. This method is convenient, but has its own technical limitations.

To begin pairing, turn the soundbar into search mode (usually by pressing the Bluetooth button for a long time or switching the mode with the Source button). On your TV, go to the Settings menu → Remotes and Accessories → Find devices or Add an accessory. Once you find the device in the list, select it to connect.

The main problem with Bluetooth connectivity is the potential for audio delay. When you watch dynamic movies or games, you may notice that the sound is behind the picture. In addition, Bluetooth bandwidth is limited, so you don't have to rely on a full-fledged Dolby Atmos or-audio in this case - the signal will be compressed by codecs like SBC or AAC.

However, for news channels, YouTube videos or background music, a Bluetooth soundbar is a great solution.Modern Xiaomi models with Bluetooth 5.0 and higher have significantly lower latency than their predecessors. If the delay is noticeable, try disabling other Bluetooth devices (mouse, keyboard, gamepad) to free up the channel.

Customization of sound parameters in the Xiaomi system

Once connected physically, it is important to properly configure the software. Xiaomi's TV operating system offers flexible calibration tools. The first thing to do is turn off the TV's built-in speakers if they don't automatically turn off to avoid echoing or mixing soundtracks.

In Settings → Sound, look at Sound Modes. Mode of Soundbars is often optimal for Movies or Custom Mode. In custom mode, you can customize the equalizer in detail, increasing the low frequencies if your soundbar lacks bass, or adjust the high frequencies for greater clarity of dialogs.

The Digital Output Format is a special feature, and if you use HDMI or Optics, you can choose between PCM and Auto/Bitstream. Auto allows the TV to determine the soundbar and send the best possible signal. PCM makes the TV decode the sound itself, which is useful if the soundbar is old and doesn't understand formats like Dolby Digital.

• 🎚️ Equator: Allows you to manually raise frequencies to improve speech intelligibility or add "warmth" to sound.
• 🔊 Volume on Turning: A useful feature to limit maximum volume so that a sharp start of advertising does not stun you.
• 🗣️ Improved dialogue: A special mode that highlights the frequencies of the human voice, making actors' speech clearer amid explosions.

Don’t forget to update your TV software. Xiaomi regularly releases patches that improve peripheral compatibility and fix bugs in the audio drivers. Check for updates in Settings → About TV → System Update.

💡

The correct configuration of the output format (Auto vs PCM) solves 90% of problems with no sound or hissing when connecting external acoustics.

Addressing common problems and conflicts

Even with the right connection, users can face a number of challenges, and one of the most common problems is that the TV remote stops controlling the soundbar volume, which often happens when using optical cables or when CEC protocols conflict, and then reconnecting the soundbar power cable (take it out of the socket for 10 seconds) and rebooting the TV helps.

Another common situation is that there is sound, but it is intermittent or cracking, which may indicate poor contact in the cable, the use of a poor-quality adapter or electromagnetic interference from a Wi-Fi router if you use Bluetooth. Try replacing the cable with a known serviceable one or push away sources of interference.

If the TV doesn't see the HDMI soundbar, check to see if the soundbar is on and if the soundbar is the right source (Input Source) for some soundbar models that don't go into standby mode, but turn off completely, so you need to turn them on separately in front of the TV.

In conclusion, connecting a soundbar to a Xiaomi TV is a simple process that dramatically changes the way you experience multimedia content. Regardless of the method you choose, whether it’s advanced HDMI eARC or simple Bluetooth communication, you will get a significant boost in sound quality, turning ordinary movie watching into a real event.
