Modern televisions are no longer just devices for watching broadcast channels, but have become full-fledged multimedia centers. It's common to find yourself wanting to listen to your favorite track or podcast, but your smartphone's sound isn't powerful enough to fill a large room. In such cases, the most logical solution is to use a acoustic system your TV, which is usually much more powerful than the speakers of a mobile gadget.
Fortunately, complex cables and adapters are no longer required to accomplish this. Wireless technologies allow you to stream audio in seconds. There are several proven protocols, such as DLNA, AirPlay And Chromecast, each of which has its own characteristics and is supported by different models of equipment.
In this article, we will examine in detail all available connection methods and consider the nuances of setting up for operating systems. Android And iOSWe'll also help you solve common connection issues. You'll learn how to turn your TV into a high-quality wireless speaker for parties or background music.
Basic requirements and network preparation
Before you begin setting up streaming, you need to make sure your infrastructure is ready. A fundamental requirement for all wireless methods is that both devices are on the same local network. This means that the smartphone and TV must be connected to the same network. Wi-Fi router.
A common mistake users make is using a guest network or different frequency bands without roaming support. If your router broadcasts 2.4 GHz and 5 GHz networks with different names (SSIDs), make sure both devices are connected to the same one. Otherwise, they simply won't "see" each other in the list of available connections.
⚠️ Note: If you're using "Guest Network" mode on your router, client isolation may block data exchange between devices. To stream music, you must use your main home network.
It's also worth checking the software version on your TV. Manufacturers regularly release updates that improve the stability of network modules and add support for new codecs. Go to your TV's settings menu and find the section Support → Software Update (on Samsung) or Settings → System → About → Update (on Android TV).
DLNA technology: a universal standard for Android and iOS
One of the most common ways to transfer media files is the protocol DLNA (Digital Living Network Alliance). This technology is built into most modern TVs and allows you to stream music, photos, and videos directly from your smartphone. No complicated setup is required if both devices support the standard.
On Android smartphones, DLNA functionality is often built into the standard player or file manager. However, for advanced functionality and better compatibility with Smart TVs from various brands (LG, Sony, Philips), it's better to use specialized controller apps. These scan the network and find all available devices. renders (TVs).
The connection process is as follows:
- 📱 Download a controller app, such as BubbleUPnP or VLC for Android.
- 📡 Make sure your phone and TV are connected to the same Wi-Fi network.
- 📺 Open the app, select the desired track and click on the sound output icon (Cast).
- 🔊 Select your TV model from the list of devices.
iPhone users can also use this method, although Apple is pushing its own standard. Apps like 8player or nPlayer They do an excellent job of finding DLNA servers and renderers. The main advantage of this method is the ability to control playback from your phone, while the TV simply acts as an external sound card.
Apple Ecosystem: AirPlay 2 and HomeKit
Apple owners are lucky to have access to technology AirPlay, which delivers high-quality audio with minimal latency. Modern TVs from Samsung, LG, Sony, and Vizio support the AirPlay 2 standard, making the purchase of a separate Apple TV box unnecessary.
To start broadcasting, you don't need to install any additional apps. Simply open the Control Center on your iPhone (swipe down from the upper-right corner or up from the bottom on older models) and tap the button. Music or Screen mirroringYour TV will appear in the list of available devices.
It is important to note the difference between the operating modes:
- 🎵 Audio streaming: The phone acts as a remote control, while the TV handles decoding and playback. The phone screen can be used for other tasks.
- 📺 Mirroring: An exact copy of the phone's image and audio is transmitted to the TV screen. This consumes more battery power.
⚠️ Note: When you first connect your iPhone to your TV, a 4-digit code may appear on the TV screen. Enter this code on your smartphone to verify that your device is trusted.
If your TV doesn't show up in the AirPlay list, check the privacy settings on the TV itself. In the menu Settings → General → Apple AirPlay Settings Make sure the feature is enabled and access is allowed for "All" or "Same networks." Sometimes, rebooting the TV's Wi-Fi module through the menu helps. Settings → Network → Network Reset.

Google Chromecast and Cast built-in
Platform Google Cast (often called Chromecast built-in) is a standard for Android TVs, as well as many models from Sony, Philips, TCL, and Xiaomi. Unlike DLNA, it is controlled via cloud services, reducing the load on the local network and smartphone.
To use this technology, you must have the application installed on your Android smartphone. Google Home, although in many cases the built-in "Cast" function in the system menu is sufficient. Streaming apps like YouTube Music, Spotify, or Yandex.Music have a built-in Cast button (the screen icon with waves) that activates a device search.
Key features of Chromecast:
- 🌐 Independence: Once playback starts, you can turn off your phone or take it out of the house, and the music will continue playing.
- 🔊 Multiroom: You can create groups of devices to play music synchronously in different rooms.
- ⚡ Saving: The smartphone does not consume battery power to transmit the stream, it only sends control commands.
If the built-in feature doesn't work, you can purchase an external Chromecast with Google TV and connect it to the HDMI port of any TV. This will instantly add protocol support even to older models. Setup is done through the Google Home app, which will guide you step-by-step through the process of connecting to a Wi-Fi network.
What should I do if the Cast button doesn't appear in the app?
If the cast button is missing from the music app interface, make sure the app has permission to access your local network. On iOS, this can be checked in Settings → App Name → Local Network. On Android, check permissions in Settings → Apps → App Name → Permissions.
Streaming via Miracast and Screen Mirroring
Technology Miracast (known as Smart View on Samsung devices, and Screen Mirroring or Wireless Monitor on others) allows you to transmit images and sound directly, without using a router. The connection is established using the protocol Wi-Fi Direct, creating a direct connection between the phone and the TV.
This method is especially useful if you don't have internet access or your router is unstable. However, it's important to keep in mind that when transmitting audio via Miracast, your phone's screen usually needs to be on, as it will broadcast exactly what's on the display.
Connection instructions:
- Press the button on the TV remote control
InputorSourceand select the "Screen Mirroring" or "Miracast" source. - On your smartphone, pull down the notification shade and find the tile labeled "Cast," "Smart View," or "Projection."
- Select your TV from the list of available devices.
- Accept the connection request on the TV screen if it appears.
Sound quality when using Miracast may vary depending on Wi-Fi network congestion, as the technology is sensitive to interference. For listening to high-resolution music (Hi-Res), this method may be inferior to DLNA or AirPlay due to possible audio compression during video transmission.
Comparison of methods and troubleshooting
Choosing the optimal music streaming method depends on your operating system, TV model, and sound quality requirements. Below is a comparison table of the main technologies to help you decide on the best connection method.
| Characteristic | AirPlay 2 | Google Cast | DLNA | Miracast |
|---|---|---|---|---|
| Platform | iOS / macOS | Android / iOS | All OS | Android / Windows |
| Sound quality | High | High | Original | Compressed |
| Phone addiction | Low | Minimum | Average | High |
| Stability | High | High | Average | Depends on interference |
One common issue is audio and video desynchronization (if you're watching music videos) or delays when switching tracks. This can often be resolved by rebooting the router. It's also worth checking if the router has a "no-download" mode enabled. AP Isolation (Access Point Isolation), which prevents devices from seeing each other.
⚠️ Note: TV menu interfaces and function names may vary depending on the manufacturer and firmware version. If you don't find the item you're looking for, look for synonyms in the "Network" or "Connections" section.
If the sound is choppy or intermittent, try moving the router closer to the TV or switching the Wi-Fi frequency. Dual-band routers sometimes incorrectly distribute traffic between 2.4 GHz and 5 GHz devices, causing packet loss when streaming.
Questions and Answers (FAQ)
Is it possible to stream music if the TV is not Smart TV?
Yes, it is possible. For standard TVs, you'll need to purchase an external set-top box, such as a Chromecast, Apple TV, Amazon Fire Stick, or Android box. These devices connect via HDMI and add Smart TV functionality, allowing you to stream music over Wi-Fi.
Why doesn't the TV see the phone in the list of devices?
The most likely cause is that the devices are connected to different Wi-Fi networks (for example, one 2.4 GHz network, another 5 GHz network with different names, or one via guest access). The issue could also be caused by the antivirus software on the phone or the client isolation setting on the router.
Does playing music affect internet speed?
Music streaming uses relatively little bandwidth (around 50-150 MB per hour for high quality), so it shouldn't significantly impact the download speed of other devices unless the channel is overloaded.
How to improve sound quality when streaming via Bluetooth (if Wi-Fi doesn't work)?
Bluetooth has lower bandwidth than Wi-Fi. For better quality, ensure both devices support the aptX HD or LDAC codec. However, for the best results, Wi-Fi technologies (DLNA/AirPlay) are still recommended, as they don't compress audio as aggressively.
