Xiaomi’s multimedia audio device: what it is and how it works

Owners of Xiaomi smartphones and smart appliances often come across the enigmatic term “multimedia audio device” in system settings or when connecting accessories. For many users, this definition remains abstract, raising questions about what exactly lies behind this formulation and how it affects the quality of playback. A multimedia audio device is not one particular gadget, but a generalized class of hardware that the Android or MIUI system identifies as the source or receiver of sound intended for entertainment content.

In the Xiaomi ecosystem, the term covers a wide range of devices, from wired and wireless headphones to smart speakers and automotive systems. Understanding how this class of devices works allows you not only to correctly adjust the sound, but also to eliminate common problems, such as desynchronization of video and audio or low volume. It is important to understand the technical nuances to squeeze the maximum of the capabilities of your gadget.

In this article, we will take a closer look at which devices fall into this category, how they pair, and which codecs provide the best data quality. You will learn how to properly prioritize sound and why sometimes the system does not see the connected headset. A deep dive into the topic will help you avoid typical mistakes when using brand technology.

Classification of devices in the Xiaomi ecosystem

When a Xiaomi smartphone or TV reports a multimedia audio device being connected, it may be thinking about dozens of different peripheral options, primarily Bluetooth headsets that are divided into fully wireless (TWS) and classic neck or full-size models, which is the segment most often associated with multimedia functionality, as it involves listening to music and watching videos.

The second big group is fixed solutions, such as Xiaomi Smart Speaker smart speakers or TV-connected saunbars, which often use not only Bluetooth, but also Wi-Fi protocols or AUX wired connection to transmit a lossless signal, and the system classifies them as multimedia because the main task is to play content, not just voice, as is the case with phone calls.

Special attention should be paid to car systems and third-party DAC-When connecting a smartphone to the multimedia system of the car via Bluetooth or USB, The phone also identifies the car as an external audio device, allowing navigational cues and music to be redirected through the machine's speakers, and understanding what's connected helps in setting volume profiles.

The key here is the difference in connection profiles: The multimedia profile (A2DP) is responsible for high-quality stereo sound, while the headset profile (HFP) is used for monophonic conversations. Xiaomi automatically switches between these modes, but sometimes the user has to intervene manually in settings to achieve the desired result.

Sound and codec transmission technologies

The sound quality depends on the audio codec used. Xiaomi devices support a wide range of compression and data transfer algorithms. The basic standard is SBC, which provides acceptable quality but has limited bandwidth. For more demanding users, aptX, aptX HD and LDAC codecs are available, which allow you to transmit sound with minimal losses.

A special place is occupied by the technology of LDAC, developed by Sony, but supported by many flagships of Xiaomi, which allows you to transmit audio stream with a bitrate of up to 990 kbit / s, which is three times higher than the Bluetooth standard.

• 🎧 SBC — A mandatory codec for all Bluetooth devices, providing basic quality.
• 🎵 aptX – improves quality and reduces latency, popular in Xiaomi mid- and high-end devices.
• 🎼 LDAC — It provides high quality Hi-Res, but requires stable signal and support from both sides.
• 📞 AAC — standard for Apple devices, but also well implemented in Android for energy efficiency.

It is important to note that codec selection is often automatic, but it can be forced to change in the developer menu. The path to these settings is usually hidden: you need to click on the build number several times in the About Phone section to activate the developer mode. Then the option or System menu will appear in the Developer's Forward, where you can find the Bluetooth Audio Codec settings.

⚠️ Warning: Forced codec that is not supported by your headphones can result in complete no sound or severe distortion.Always check the headset specifications before changing system settings.

Using advanced codecs increases the battery load of your smartphone. If you care about your battery life over audiophile quality, it makes sense to leave standard settings or choose an AAC codec that balances quality and power consumption. Android tries to choose the best option, but manual tuning gives you better control.

Configuring and managing the connection

The process of pairing multimedia devices in the shell MIUI Or HyperOS, as simplified as possible. When you open a case of compatible headphones next to a Xiaomi smartphone, you often see an animated window offering to connect. This works thanks to the fast Pair protocol, which reads the message. MAC-Device address and automatically configures the required profiles.

For manual connectivity, go to Settings → Bluetooth. This shows the list of available devices. If your media device is not in pairing mode. For most Xiaomi headphones, this means holding a button on the case or touch zone for a long time until the indicator flashes.

The devices already connected are managed through a notification panel or a Mi Connect widget, and you can see the charge level of each headphone separately, which is a unique feature of the ecosystem, and you can also find headphones that make them loud if you lose them in the apartment.

In some cases, you need to reassign the control buttons. Standard actions (one touch, double, triple) can be reconfigured to suit your needs. For example, a triple touch can be assigned not to switch the track, but to call the voice assistant Xiao AI or Google Assistant. This is done in the Bluetooth settings menu by clicking on the gear next to the device name.

Resolving Sound and Delay Problems

One of the most common problems with wireless media is the desynchronization of audio and video, especially when watching videos on social networks or games, and latency depends on the quality of the Bluetooth connection, the codec version and the load of the radio channel.

To minimize delays in developer settings, you can activate the option “Disable Absolute Volume.” Sometimes this helps stabilize the connection. It’s also worth trying to clear the Bluetooth cache: to do this, find “Bluetooth” in the application menu, go to storage and click “Clear Cache.” After that, the phone will need to restart.

Another cause of problems can be energy saving: Xiaomi’s system aggressively optimizes the work of background processes, which sometimes leads to the shutdown of the Bluetooth module to save energy. To avoid this, look in the list of applications “Bluetooth” and “Bluetooth MIDI Service” and set the energy saving mode in the position “No restrictions”.

⚠️ Attention: If the connection problem remained after resetting Bluetooth, it may be due to hardware compatibility of Bluetooth versions.Outdated headphone models may not work properly with new Xiaomi smartphones.

Using a Smartphone as an Audio Device

Xiaomi's smartphone can be a source of sound, but also a receiver of sound. Translation or Cast allows you to output sound from your phone to a smart speaker or TV, which is convenient when you need to voice a video for a large company or use your phone as a microphone for a remote speaker.

To implement this scenario, devices must be on the same Wi-Fi network. In the notification curtain, select Translation or use the Google Home app. In the list of available devices, select your speaker or TV. After that, all media content, including system sounds, will be transmitted to an external device.

There is also the possibility of using the phone as a microphone for PCs through special applications, but within the Xiaomi ecosystem, the feature of using the phone as a remote for a Mi TV is more interesting. In this case, the sound can be broadcast back to the phone, which allows you to watch TV at night without disturbing others.

Model comparison and device selection

When choosing a multimedia device for bundling with a Xiaomi smartphone, you should pay attention to protocol support. Flagship headphone models such as the Xiaomi Buds 4 Pro offer the best integration, including spatial audio and adaptive noise cancellation. Budget models such as the Redmi Buds series offer good value for money, but can use simpler codecs.

If you choose a smart speaker, Chromecast built-in models will be more stable and functional in conjunction with Android. Simple Bluetooth speakers are deprived of the ability to control over Wi-Fi and voice commands, which limits their multimedia potential in a smart home.

• 🏆 For audiophiles: Supported models LDAC and Hi-Res Audio Wireless.
• 🏃 For sport: Devices with protection IPX4 and reliable mounting, even if the codec is basic.
• 🏠 Home: Smart speakers with Wi-Fi and voice control.

Battery life is an important criterion. Multimedia features such as Active Noise Canceling (ANC) significantly reduce battery life. When choosing a device, keep in mind that the claimed run time is often indicated for non-ANC mode.

⚠️ Note: When buying Xiaomi devices for use with iPhone, remember that some branded features (pop-up, in-app equalizer setting) may not be available or work with limitations.
