Modern Smart TVs from Xiaomi and Redmi are equipped with powerful multimedia capabilities that are often underestimated by ordinary users. The built-in acoustic system of these devices is able to produce high-quality sound that is much superior to standard computer speakers or cheap Bluetooth speakers. Using the TV as a full-fledged music center is not only convenient, but also allows you to enjoy your favorite tracks in high quality without buying additional equipment.
However, many owners have difficulty simply streaming audio from a smartphone or laptop to the big screen. Android TV or PatchWall’s proprietary shell interface may have its own nuances that obscure the obvious features. In this article, we’ll take a look at all the possible ways to stream audio, from built-in features to third-party applications.
You will learn how to set up a wireless connection, what codecs your TV supports, and how to avoid audio delays when watching videos or listening to music. We will look at both wired and wireless methods so you can choose the best option for your situation.
Use of the built-in Chromecast function
The most native and stable way to transfer content to Xiaomi Mi TV devices is Google Cast (Chromecast built-in) technology, which is built directly into the TV operating system and does not require additional receivers. To work, you will need a mobile device based on Android or iOS, connected to the same Wi-Fi network as the TV.
The process of launching the broadcast is as simple as possible and implemented at the application level. You do not need to look for complex settings in the menu of the TV, just open a supported application on your smartphone. Among these applications are popular streaming services like YouTube, Netflix, Spotify, Yandex.Music and many others.
The app will automatically detect available devices on the local network. You just need to click on the broadcast icon, which usually looks like a rectangle with waves in the corner of the screen. Once you select your Xiaomi TV from the list, playback control will go to the TV, and the smartphone will work as a remote.
⚠️ Warning: Make sure your TV has Google Cast enabled. Check this out in Settings. → Annexes → System applications → Built-in Chromecast.If the service is disabled, the stream won't work.
An important advantage of this method is the ability to control the playback queue and volume directly from the phone while the TV is decoding the audio stream, which frees up the resources of the smartphone and allows you to use it for other tasks without interrupting music.
💡
For the best sound quality in the source app settings (such as Spotify or YouTube Music), choose the highest available audio quality, as the TV is capable of playing streams with high bitrate.
Screen and sound broadcast via Miracast
Miracast technology (often referred to simply as “Translation” or “Wireless Display”) allows you to duplicate a smartphone screen onto a TV along with sound. Unlike Chromecast, which streams content from a link, Miracast streams video in real time. It’s a versatile method that works even with applications that don’t have a built-in Cast button.
To connect to Xiaomi TVs with PatchWall shell or pure Android TV, you need to activate the reception mode. It is usually in the signal source menu or in quick settings. On Android smartphones, this feature can be called variously: Translation, Smart View (Samsung), Projection (Huawei/Honor) or Screen Replay.
The algorithm of actions is as follows:
- 📺 Open the Miracast app on your TV or select the source of the Wireless Display signal».
- 📱 On the smartphone, lower the notification curtain and find the screen broadcast button.
- 🔗 Wait for your TV name to appear on the list of available devices.
- ✅ Click on the name to establish the connection and start mirroring.
It should be borne in mind that when using Miracast, the smartphone screen must be turned on, which can lead to increased battery consumption, and in addition, a stable Wi-Fi signal is required to transmit high-quality sound, since the video stream and audio track are transmitted simultaneously.
Connection via Bluetooth adapter
Many Xiaomi TVs have a built-in Bluetooth module, which allows them to be used as an external speaker system. You can connect your smartphone, tablet or laptop over Bluetooth and stream any system sound directly to the TV speakers. This is ideal for listening to music from non-Cast apps or for gaming.
The pairing process is standard for Android devices. You need to go to the Bluetooth settings on your TV and turn on the search mode. Then on your smartphone you need to find the device with the name of your TV (for example, MI TV or Redmi TV) and perform pairing. In some cases, you may need to confirm the code on the TV screen.
However, there is an important caveat: not all Xiaomi TVs can receive Bluetooth audio in A2DP Sink mode (receiver). Some models only work in source mode (connect Bluetooth headphones to TV). To check support, try to find your phone in the list of available devices on the TV.
⚠️ Attention: Bluetooth can cause noticeable latency, which is critical for gaming or video where the audio is not synchronized with the image, but is completely invisible when listening to music.
If you don't have Bluetooth built-in on your TV or it doesn't work as a receiver, you can buy an external USB Bluetooth adapter. However, support for such adapters on Android TV is limited and requires drivers on the system, which is rare.
☑️ Checking Bluetooth connection
Comparison of connection methods: table
To make it easier for you to choose the right way, we have prepared a comparative table of basic broadcast methods, which will help you to understand which option is best for your tasks: listening to music in the background, watching clips or playing games.
| Method | Sound quality | Delay (Latency) | Phone battery consumption | Stability |
|---|---|---|---|---|
| Chromecast | High (up to Lossless) | Minimum | Low. | Tall. |
| Miracast | Medium/High | Medium | High-pitched | Depends on Wi-Fi. |
| Bluetooth | Medium (SBC/AAC compression) | Tall. | Medium. | Medium |
| DLNA | High (original) | No (local file) | Low. | Tall. |
As you can see from the table, Chromecast and DLNA are best suited for listening to music, as they provide better quality and do not land the smartphone battery. Miracast is good for video, where synchronization is important, and Bluetooth is for versatility when other methods are not available.
Use of DLNA and Network Players
If you have a large collection of music in FLAC, WAV or MP3 formats on your smartphone or computer, you can stream them directly over the local network using DLNA technology. Xiaomi TVs work perfectly with popular network players such as VLC for Android or the built-in MI Video player.
To implement this method, you do not need to configure anything on the TV, except for a Wi-Fi connection. On a smartphone, you just need to open a file in a player that supports casting (for example, VLC), and choose a playback device.
This is especially true for audiophiles who value sound quality, and direct file transfer eliminates the additional stream compression that often occurs when streaming via cloud services or Bluetooth, and you get the sound exactly as it was recorded.
How to improve buffering when streaming heavy files?
Broadcasting sound from a computer (Windows/macOS)
PC owners can also use a Xiaomi TV as external speakers. On Windows 10 and 11, this feature is built-in and is called Connection or Caste to Device. You don't need to install third-party software if the TV supports DLNA/UPnP.
To connect, open the Windows Action Panel (Win + A) and select Connect. If the TV is not visible, make sure that the system settings include wireless display support. MacOS is more complicated because Apple uses its AirPlay protocol. To stream audio from Mac to Android TV, you will need to install third-party software, such as a Chrome browser plugin or specialized utilities like AirServer (on the TV side).
Another reliable way for a PC is to use Google Chrome. Open a tab with music (like the web version of Yandex.Music), click three dots in the browser menu and select Translate. From the source, specify Tab or Whole Screen, and the sound will go through the TV.
⚠️ Note: When broadcasting audio from a computer through the Chrome browser, audio and video in clips may be dissynchronized. For purely music tracks, this does not matter, but for video content, it is better to use native applications on Smart TV.
Solution: No sound or interruption
Even with the right setup, users can encounter problems, the most common being the lack of sound when connecting via Miracast or HDMI (if an adapter is used), in which case you need to manually switch the audio output in the phone settings to an external device.
Another common problem is intermittent sound or stuttering, which almost always indicates problems with the Wi-Fi network, if the router is overloaded or the signal is weak, the play buffer does not have time to fill up, in which case, try to bring the router closer to the TV or switch to 5 GHz.
It’s also worth checking your smartphone’s energy saving settings. Aggressive energy saving modes can kill the background streaming process, considering it an unnecessary resource user. Add a streaming app (YouTube, Spotify, VLC) to the battery exceptions.
💡
The quality of wireless audio broadcasting is 90% dependent on the stability of the Wi-Fi connection. If the music is constantly interrupted, check the router signal first, not the settings of the TV.
