Integrating Sony’s high-quality acoustics into the Xiaomi-based smart home ecosystem (MIUI TV) is a logical step for those looking to unlock the potential of embedded soundtracks in movies and games. The standard sound of flat TVs often fails to convey the depth of bass or clarity of dialogue that specialized systems provide. The right connection of these devices turns ordinary movie watching into a full-fledged cinematic experience with surround sound.
The pairing process may seem complicated because of the variety of interfaces and operating system versions, but in practice it comes down to choosing the right cable or data protocol. You have to choose between wired options that provide maximum quality without delay, or wireless solutions to minimize the number of wires in the interior. Each method has its own technical nuances that must be considered for stable operation.
In this guide, we will take a look at all the switching options available, from modern digital standards to classic analog connections. You will learn how to activate the ARC protocol to control the volume of a single remote, and what audio codec settings should be changed in the TV menu.
Choosing the optimal connection interface
The first and most important step is to analyze the available ports on the back or side of your Xiaomi TV and the back of the Sony soundbar.Modern models tend to feature a full set of digital interfaces, while devices of the past may require adapters or specific cables.
The most preferred option for modern home theater systems is to use an HDMI interface that can deliver multi-channel sound without loss of quality. If your soundbar and TV model support the eARC (Enhanced Audio Return Channel) standard, you will get access to object-oriented sound formats such as Dolby Atmos and DTS:X. This provides incredible detail and spatial positioning of objects.
⚠️ Note: Not all ports HDMI Xiaomi TVs support a return audio channel. ARC or eARC near the connector, usually HDMI 1 HDMI 2.
For older models or in situations where HDMI is busy with game consoles, you can use the Toslink optical output. This interface transmits digital audio signals over a light guide, which completely eliminates electromagnetic homing, but has a bandwidth limitation and does not support the latest compression formats. However, for stereo and basic surround sound, its quality is quite sufficient.
- 🔌 HDMI ARC/eARC: Best choice for sound quality and ease of control of one remote.
- 🔦 Optical cable: A reliable alternative if HDMI It is busy, but without the support of the latest codecs.
- 📡 Bluetooth: Convenient for wireless connectivity, but can delay and compress audio stream.
- 🎧 3.5 mm AUX: Analog version of the latest resort, the sound quality will be much lower than digital methods.
Connection via HDMI ARC and eARC
Using an HDMI backup audio channel (ARC) cable is the “gold standard” for soundbar connectivity, which allows you to transmit sound from your TV to your speaker while simultaneously controlling the volume and onset of devices from the remote of your Xiaomi TV.
The physical connection process is extremely simple: one end of the cable is inserted into the port. HDMI (ARC) on the TV, and the other to the port HDMI OUT (ARC) It's important not to confuse the ports, because you're connected to the normal one. HDMI-When the soundbar is input, it doesn't activate the sound return function. When the physical connection is made, the system automatically recognizes the new device if the function is enabled. CEC.
☑️ Connection check HDMI ARC
CEC (Consumer Electronics Control) technology is critical for comfort, allowing you to synchronize the operation of devices: when you turn on the TV, the soundbar will automatically turn on, and the volume adjustment of the Xiaomi remote buttons will control external acoustics, which can be called differently on the menu of Xiaomi TVs, for example, “HDMI Control” or “HDMI Control”.
If you own top-end eARC-enabled models, make sure that the audio settings are “Auto Pass-through” or “Bitstream” mode, which will allow the TV to not decode the sound itself, but to transmit the original digital stream directly to the Sony soundbar decoder, which will do a much better job than the built-in TV.
Optical output setting (Toslink)
The optical connection remains popular because of its versatility and immunity from interference.The Toslink cable transmits a light signal, so it is absolutely immune to electromagnetic interference, which sometimes happens with cheap ones. HDMI-You'll need a cable with a square section of connectors protected by plastic plugs to connect.
When connected via optics, you lose the ability to control the soundbar from the TV remote via the CEC protocol, since the optical cable only transmits audio data. You will have to use two remotes: one for managing content on Xiaomi, the other for adjusting volume and equalizer modes on Sony. However, many users find this an acceptable compromise for the sake of stability of the connection.
In the TV settings, you need to manually switch the output. Go to the Settings → Sound → Audio output menu and select Optical or S/PDIF. It is also important to set the output format to PCM or Dolby Digital, as raw bitstream through optics may not play on some soundbar models.
⚠️ Warning: Optical cables are fragile inside, and when bending at less than 90 degrees, the fiber can break, causing the sound to disappear completely or collide.
The advantage of this method is that you can connect the soundbar to a TV that is already occupied by another device via HDMI, such as a game console, so you just display the video on the screen and route the sound through a digital output to external acoustics, which is especially true for owners of TVs with limited ports.
Wireless connection via Bluetooth
Bluetooth technology offers maximum freedom from wires, which is ideal for minimalist interiors. Xiaomi TVs with Bluetooth 4.0 and higher easily detect Sony soundbars that support the A2DP profile. However, it is worth considering that wireless transmission always introduces a small latency between video and audio.
To pair, put the soundbar in mode (usually by holding the Bluetooth button on the case or remote) and start searching for devices in the TV menu Settings → Remotes and accessories → Adding the device. Once the device is successfully connected, the system will remember the device, and the reconnection will occur automatically when both gadgets are turned on.
How to reduce the latency of the sound over Bluetooth?
Bluetooth audio quality is limited by compression codecs like SBC or AAC, so you can’t expect studio quality or support for formats like Dolby TrueHD, which is great for watching news channels, YouTube or listening to music where bitrate and multichannel requirements are not as critical as in theater systems.
- 📶 Range: Stable operation within the 5-8 footprint.
- 🔋 Energy consumption: Minimum impact on overall system energy efficiency.
- 🎵 Codecs: Support SBC, AAC, LDAC (It depends on the soundbar model).
Configuration of sound settings in MIUI TV
Once you're physically connected, you need to properly configure the software part of the Android TV or PatchWall operating system installed on your Xiaomi TV. By default, the system can try to play audio through the built-in speakers, ignoring the external system connected. The primary task is to switch output priority.
Go to Settings → Sound. Find Audio or Dynamics and select the appropriate interface (HDMI ARC, Optical Output). Next, you need to adjust the digital audio format. For maximum quality, choose Auto or Pass-through mode, which will allow the soundbar to decode Dolby Digital Plus or DTS signals.
💡
If the sound is interrupted or wheezing, try turning off the Dolby Volume or Auto Volume Control function in the sound settings, as these may conflict with soundbar processing.
You should also look at the synchronization settings, and if you notice that the actors' lip movements don't match the sound, look for "Sound Lag" or "Lip Sync" in the advanced audio settings. Adjust the value in milliseconds until the image and the audio are all in one, and a 50-100 ms shift is usually enough.
For users who need fine-tuning, Equalizer mode is available, where you can select profiles such as "Cinema", "Music" or "News", and you should choose a "Cinema" or "Standard" profile so as not to over-empower the bass artificially, since the Sony soundbar already has its own signal processing system.
Diagnostics and solution of common problems
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 HDCP or handshake versions of the protocol are incompatible between devices of different generations, in which case the full reboot cycle helps: turn off the TV and soundbar from the socket for 30 seconds, then turn on the acoustics first, then turn on the TV.
If there is a sound but it is quiet or distorted, check the settings on both devices. Make sure the soundbar does not activate Night Mode, which dynamically compresses the range of loud and quiet sounds. Also check if the TV is set to maximum volume, as some Xiaomi models at 100% volume can contribute digital distortion to the signal going to the external DAC.
| Problem. | Possible cause | Decision |
|---|---|---|
| No sound. | Not the right way out. | In the sound settings, select HDMI ARC |
| Crackling in the speakers | Interference or bad cable | Replace HDMI cable or move router |
| Razsynchronization | Delay in decoding | Configure Lip Sync or change format to PCM |
| The remote is down. | HDMI-CEC is disabled | Enable HDMI control in settings |
⚠️ Note: When you update your Xiaomi TV firmware, the audio settings may be reset to factory. After each major update, check if the audio output has switched back to the factory «TV Speaker».
In rare cases, the problem may lie in the cable itself. Cheap HDMI cables may not support the bandwidth required to transmit high-resolution audio along with 4K video. If you use an older cable, replace it with a High Speed HDMI certified with Ethernet support.
💡
90% of audio problems are solved by setting the format of the output (Pass-through) and activating the HDMI-CEC function in the menu of the TV.
Connection details for different Sony models
Sony’s soundbar lineup is extensive, and the HT, HW and PlayStation soundbar series models have their own characteristics. For example, the HT-A7000 series models require an eARC-enabled HDMI cable to run Dolby Atmos, while simpler models like the HT-S400 may be limited to a standard ARC.
Some Sony soundbars have an "Auto Power On" feature that allows them to be powered on with the TV, and to work with this feature over HDMI, you need to have the power control option active in the soundbar settings (via the remote or app), without which you will have to manually turn on the acoustics every time.
If you use a Sony soundbar in conjunction with a subwoofer, make sure that the wireless connection between them is established before connecting to the TV. The display on the front of the soundbar will tell you the status: flashing light usually means search mode or connection error, and even glow - ready to go.
Enhanced capabilities and applications
Owners of modern Sony soundbars can significantly expand the functionality of the device by installing the Sony | Music Center or Sony | Soundbar app on a smartphone. Through this interface, deep equalizer tuning is available, which is often not available through the standard menu of the Xiaomi TV.
The app allows you to create custom profiles for different use cases, for example, a separate profile for games with an emphasis on high frequencies for steps and a separate one for movies with amplified low frequencies. It is also convenient to update the soundbar firmware through the application, which can fix known compatibility bugs with Android TVs.
- 📱 Control: Full control of settings through a smartphone.
- 🎚️ Equator: Accurate frequency range setting.
- 🔄 Updates: Install the latest security and functionality patches.
Using voice assistants built into the soundbar (Google Assistant), also requires initial configuration through the application. After that, you can control playback, ask for the weather or turn on the smart home with your voice, even if the Xiaomi TV is turned off, turning the speaker system into a smart home control center.
