Owners of modern media players from Xiaomi often encounter a mysterious acronym in audio settings that promises cinematic sound right in the living room. DTS Sound technology is a complex audio processing algorithm designed to create a surround effect even when using a standard stereo system or built-in TV speakers. For home theater enthusiasts, understanding the principles of this codec becomes the key to unlocking the full potential of their device.
Many users mistakenly believe that having a logo on the box guarantees automatic operation of all functions without additional settings. In fact, digital signal processing requires the correct connection and compatibility of all links of the chain, from the signal source to the final speakers. In this article, we will discuss in detail what lies behind this term, why it may not work on your Xiaomi Mi Box or TV Stick, and how to squeeze the most out of available hardware.
It is worth noting that the multimedia market is saturated with various coding standards, and DTS is one of the main competitors of the Dolby Digital format, the difference between them lies not only in compression algorithms, but also in the licensing policies of developers, which directly affects the functionality of budget and medium-budget gadgets. Understanding these nuances will help to avoid disappointment when buying new equipment or trying to customize existing ones.
What is hidden behind the abbreviation DTS in the interface Android TV
When you see the DTS Sound option on your Xiaomi console menu, it’s a hardware and software package responsible for decoding and playing back audio streams encoded by DTS, Inc. It’s not just an equalizer that changes timbre, but a full-fledged decoder that converts compressed digital data into an analog signal or transmits them unchanged to external acoustics.
In the Android TV ecosystem, on which all modern Xiaomi boxes are based, support for this format is often implemented through system libraries. Decoding can occur by software, which loads the CPU, or hardware, if the chipset has a built-in decoder. It is important for users to distinguish between these concepts, since software processing can cause sound and image to be desynchronized when playing heavy files.
⚠️ Warning: Activating passthrough without a connected receiver can result in no sound at all, as the TV will not be able to decode the stream.
Xiaomi’s audio settings interface typically offers multiple modes of operation. You can choose to automatically define format, surround priority, or forced stereo. DTS Sound’s post-processing algorithm can also include virtualization, creating the illusion of multi-channel sound from two speakers, which is especially true for owners of simple TVs without soundbars.
Technical Differences Between DTS and Dolby Digital on Xiaomi
The perpetual confrontation between the two giants of the audio industry is reflected in the functionality of Xiaomi devices. Although both formats serve the same purpose of transmitting multichannel audio, their technical implementations differ significantly. DTS traditionally uses a lower degree of compression, which theoretically provides a higher bitrate and therefore better sound quality than Dolby Digital under similar conditions.
Xiaomi Mi Box S devices and newer models usually support both standards, but their implementation depends on the regional version of the firmware. Global versions often have all the necessary licenses, while Chinese versions may require the installation of third-party players for full operation. License restrictions are the main reason why some users can not activate the desired mode in a standard application.
A comparison table will help you better understand the differences in the characteristics of supported formats:
| Parameter | DTS Digital Surround | Dolby Digital Plus | PCM (Stereo) |
|---|---|---|---|
| Maximum bitrate | 1536 kbps | 6144 kbps | Depends on the frequency. |
| Channel | 5.1 | 7.1 | 2.0 |
| Data compression | Moderate. | High. | No compression. |
| Resource requirements | Average. | Low. | Minimum |
When choosing between formats in Xiaomi’s settings, you should focus on the capabilities of your acoustic system. If you have an old stereo receiver connected, turning on surround sound may not have any effect, and in some cases even worsen the quality due to the wrong downmix of channels.
How to activate and configure DTS Sound in the console menu
To enable the necessary features, the owner of a Xiaomi device needs to go through several steps in the system menu. First, go to the settings section, which can be called Settings or Settings, and then select the item associated with the device or preferences. Depending on the version of the PatchWall shell or pure Android TV, the path may differ slightly, but the logic remains the same.
Find the Sound and Vibration or Sound section. Inside you'll need Digital Output or Digital Output. That's where the key switches are hidden. To activate full decoding, select Auto or Pass-through. If you're using the TV's built-in speakers over HDMI, try PCM mode so that the console decodes the sound itself and sends it back to the finished stream.
After the settings change, the system can request confirmation or automatically restart the audio service. Check the health is carried out by running a test video file or streaming content marked 5.1. If the sound appeared only in stereo mode, then the data chain is interrupted somewhere or the receiver does not support the selected format.
☑️ Customization of sound on Xiaomi
Compatibility issues and lack of license on the device
One of the most common problems faced by users of Xiaomi TV Stick and boxes is the message about the lack of a license or the inability to include the desired format. This is due to the fact that Xiaomi, like many other manufacturers, has to pay royalties for each device sold. In some budget models or specific regional firmware, DTS support can be software-disabled.
If the audio settings don't have the necessary options, and when playing files, an error occurs "Audio format not supported", this is a sure sign of a lack of a license, in which case the standard Mi Video player or Android system player will not be able to process the track, the solution lies in installing third-party software that has its own built-in codecs and is not subject to system restrictions.
⚠️ Warning: Installing third-party codecs from unknown sources may lead to unstable system operation or conflicts with the system audio driver.
Also worth considering is the Android version. On older versions of the operating system (like Android 9 and below), support for new coding standards could be limited architecturally. Updating firmware to the latest available version via Settings → About Device → System Update sometimes adds missing components and fixes compatibility errors.
Using third-party players to play DTS
When Xiaomi’s system tools can’t decode, specialized applications come to the rescue, and VLC for Android has been a leader for many years, with its main advantage being its own built-in codecs that allow you to play almost any audio and video formats without depending on the capabilities of the TV or receiver itself, which is ideal for watching movies from a hard drive.
Another powerful tool is Kodi, which not only plays video, but also fine-tunes the audio output. In the Kodi settings (Settings → System → Audio), you can force passthrough for DTS and Dolby Digital to beam raw signals to your external receiver, which will take over the decoding, ensuring the best possible sound quality.
List of recommended players for Xiaomi
When using third-party players, it's important to set the output correctly. If you want the receiver to decode the sound itself, you need to select "Through" or "Passthrough" in the player settings. If the sound goes directly to the TV, you'd better leave the decoding on the application side by selecting PCM output mode or the like.
HDMI ARC and optical output setup for surround sound
To transfer multi-channel audio from Xiaomi to external acoustics, it is critical to use the HDMI interface correctly. HDMI ARC (Audio Return Channel) technology allows you to transmit sound from the TV to the saunbar or receiver over the same cable that the image is traveling through. However, if the console is connected directly to the receiver and then to the TV, the setting is simplified.
When using optical output (Toslink) via HDMI adapter or directly (if any), be aware of bandwidth limitations. Optics does not support the latest formats without compression, such as Dolby TrueHD or DTS-HD Master Audio. In this case, the sound will automatically convert to the basic Dolby Digital or DTS Core, which is still better than conventional stereo.
The TV menu also needs to activate the appropriate settings. Often the default is to output audio through the built-in speakers. Go to Settings → Sound → Audio output and select Optical output or HDMI ARC. It is also recommended to turn on Digital Out mode and select Auto or Pass-through.
💡
Use high-quality HDMI cables 2.0 and higher, especially if you plan to stream 4K HDR video along with surround sound. Cheap cables may not be able to cope and cause artifacts.
If after all the manipulations, the sound is only in stereo, check if the settings on the TV itself are "Stereo" instead of "Auto" or "Volume." Some TV manufacturers force the channels to mix into two, if not detected, external system support.
Frequently encountered errors and methods of their elimination
Even with the right setup, users can run into problems. One of the most common is lip-sync error, which often happens when software decodes heavy formats on weak processors. To solve the problem with your TV or receiver settings, look for an Audio Delay or Lip Sync setting and pick up the latency value.
Another common error is the complete absence of sound when Passthrough is enabled, which means that the console sends a digital stream and the receiving device (TV or receiver) cannot read it, in which case you need to temporarily switch the Xiaomi audio settings to PCM mode to return the sound, and then recheck the connection and support of the receiver formats.
⚠️ Warning: Frequently changing audio settings without restarting the device may cause the audio driver to freeze.If the sound is gone, perform a full reboot of the console via the menu or disconnect from the network.
Also worth mentioning is the problem with specific applications: Some streaming services (such as Netflix or Disney+) can ignore the system settings of the sound and use their own algorithms. If one application has sound and another does not, the problem lies in the compatibility of a particular application with your version of Android TV.
💡
The main reason for the DTS sound problems on Xiaomi is the mismatch between the settings of the console output and the capabilities of the receiving device (TV or receiver).
Comparison of Xiaomi models for support of audio codecs
Not all Xiaomi devices are created the same in terms of audio. Flagship models such as Xiaomi Mi Box S (2nd Gen) or Xiaomi TV Stick 4K are equipped with more modern chipsets that support hardware decoding of a wide range of formats, including Dolby Atmos and DTS. Budget models such as the first version of Mi TV Stick (Full HD) can have limitations.
Owners of older models, such as the Mi Box 1 or Mi Box 3, should consider that these devices run on older versions of Android, where support for modern codecs could be reduced by the manufacturer over time. VLC It is the only way to get a good sound.
When choosing a new console, pay attention to the specifications. Having a DTS logo on the box is a good sign, but it is always a good idea to check user reviews for your version of the firmware. Sometimes software updates can both add new features and, conversely, remove support for some formats due to licenses expiring.
