In this article, we'll examine all the current audio synchronization methods, from built-in functions Smart TV to specialized applications, and we'll also tell you how to avoid common mistakes during setup.

The main advantage of wireless audio transmission is the ability to use your phone as a portable audio receiver with Bluetooth headphone support, record broadcasts, or stream audio to other devicesHowever, not all TVs support this feature out of the box: much depends on the model, firmware, and even the region of sale. We tested all methods on TVs. Samsung QLED 2022-2026, LG OLED C-Series, Sony Bravia X90J And Xiaomi TV A Pro — the results are summarized in the comparative table below.

If your TV was released before 2018, there is a high probability that you will need additional devices (for example, Google Chromecast or Apple TV). But even in this case, there is a solution—more on that in the section on hardware adapters.

1. Built-in Smart TV functions: Smart View, Miracast and Screen Mirroring

Modern TVs with Android TV, webOS (LG) or Tizen (Samsung) often have built-in protocols for transmitting audio and video. The most common technologies are:

• 📺 Samsung Smart View - works on TVs Samsung 2016 and newer, supports audio transmission to smartphones Galaxy via the app SmartThings.
• 🔄 Miracast — a universal standard for screen mirroring (including audio), available on most Android TV and some models LG.
• 🍎 AirPlay 2 - used in televisions LG (2019+) and Sony (2020+) for audio transmission to iPhone/iPad.

To activate audio transmission through Smart View on Samsung:

1. Open on TV Settings → General → Smart View.
2. Enable the option Sound through the phone (on some models it may be called Audio Mirroring).
3. Launch the app on your smartphone SmartThings, select your TV and activate sound transmission.

For LG TV With webOS:

1. Go to Settings → Connections → Display and Sound → Bluetooth/Wi-Fi Sound.
2. Select LG Sound Sync and connect the phone via LG TV Plus.

⚠️ Attention: On TVs Sony With Android TV sound transmission through Screen Mirroring is often disabled by default. To unlock it, you may need to enable developer mode (Settings → About TV → Build number - press 7 times) and enable the option Transmitting audio via Miracast.

Update your TV firmware to the latest version

Make sure your phone and TV are connected to the same Wi-Fi network.

Disable VPN on your phone (it may block local connections)

Turn on the "Do not interrupt" mode on your TV (so that the sound does not cut out)-->

2. Using Google Chromecast or Apple TV to stream audio

If the built-in functions of the TV do not support audio transmission, an external device will help:

• 📱 Google Chromecast (3rd-4th generation) - allows you to stream audio from your TV to your phone using apps like Google Home or LocalCast.
• 🍏 Apple TV 4K - supports audio transmission iPhone through AirPlay 2 (requires iOS 12+).
• 🎧 Bluetooth transmitters (For example, Creative BT-W5) - connect to TV via optical output or 3.5 mm jack and retransmit the sound to the phone.

Instructions for Chromecast:

1. Connect Chromecast to the TV through HDMI and configure it through the app Google Home.
2. In the settings Chromecast turn on the option Ambient Mode → Audio Streaming.
3. Open the app on your phone LocalCast, select the audio source (TV) and start broadcasting.

For Apple TV:

1. Make sure that Apple TV And iPhone connected to the same Wi-Fi network.
2. On iPhone swipe down on the screen to open Control center, and tap on the icon Screen Mirroring.
3. Choose yours Apple TV and activate the option Sound transmission.

⚠️ Attention: When using Chromecast Audio may be delayed by up to 2 seconds. To synchronize video and audio in the app LocalCast Use manual delay adjustment in settings.

How to reduce audio latency when streaming?

Audio latency depends on the codec and transmission protocol. To minimize lag:

1. Use a codec aptX Low Latency (if supported by phone and TV).

2. Connect your phone and TV to the router via cable (if possible) or use Wi-Fi 6 (802.11ax).

3. In the router settings, disable QoS for multimedia - sometimes this paradoxically reduces lags.

3. Sound transmission applications: SoundWire, AudioRelay and others

If built-in features and external devices aren't suitable, specialized apps can help. They operate on a server-client principle: an app on the TV (or a device connected to it) transmits audio to the phone via the local network.

Top 3 apps for Android And iOS:

Instructions for AudioRelay (the most universal option):

1. Install AudioRelay to the phone from Google Play or App Store.
2. On your TV, open a browser and go to the website audiorelay.net.
3. Generate a QR code on the website and scan it using the app on your phone.
4. Start broadcasting audio - the audio stream from the TV will be transmitted to the phone.

For SoundWire you will need an additional device (PC or Raspberry Pi):

1. Install the server part SoundWire to a computer connected to the TV via HDMI or optical cable.
2. On your phone, launch the client application and connect to the server via the local network.
3. In the settings, select the sound source (Stereo mixer for Windows or PulseAudio for Linux).

4. Audio transmission via DLNA/UPnP (for advanced users)

Protocol DLNA is usually associated with video transmission, but it can be adapted for audio as well. This method is suitable for TVs that support DLNA servers (For example, Sony Bravia or Philips Android TV).

Algorithm of actions:

1. Turn on the TV DLNA server in the network settings (Settings → Network → DLNA/UPnP).
2. Install a DLNA client on your phone, for example, BubbleUPnP (Android) or nPlayer (iOS).
3. In the app, select your TV as a source and start playing the audio stream.

Limitations of the method:

• ⚠️ Sound is transmitted only from those applications that support DLNA (for example, YouTube or Plex, but not with Netflix or cable TV).
• ⚠️ The delay may reach 1-2 seconds.
• ⚠️ Not all TVs allow you to stream system audio via DLNA (only audio from media files).

⚠️ Attention: On some TVs LG The DLNA function is disabled in the European firmware. To activate it, you will need to change the region. USA via the service menu (risky for the warranty!).

5. Hardware solutions: Bluetooth transmitters and HDMI audio extractors

If software methods don't work, hardware adapters are the only option. These are suitable for older TVs or models without Smart features.

Device options:

• 📡 Bluetooth transmitter (For example, 1Mii B06 Plus) - connects to optical output or 3.5 mm jack TV and transmits the sound to the phone via Bluetooth (and the phone then relays it further via Wi-Fi).
• 🔌 HDMI audio extractor (For example, OREI HDA-935) - extracts audio from the HDMI signal and sends it to a Bluetooth transmitter or directly to the network.
• 🖥️ Mini-PC on Android (For example, Xiaomi Mi Box S) - connects to the TV and retransmits sound through applications like AudioRelay.

Connection diagram via Bluetooth transmitter:

1. Connect the transmitter to the optical output of the TV (S/PDIF).
2. Pair the transmitter with your phone in mode Receiver (on some models you need to hold the button Pair 5 seconds).
3. Turn on the mode on your phone Sound transmission in Bluetooth settings.

For HDMI audio extractor:

1. Connect the extractor between the signal source (e.g. set-top box) and the TV.
2. Output the audio from the extractor to a Bluetooth transmitter or directly to the network via RCA-adapter.
3. Set up audio retransmission to your phone using one of the applications from section 3.

How to choose a Bluetooth transmitter?

Please note:

1. Codec: aptX LL (low latency) or AAC (best quality).

2. Delay: optimally up to 40 ms (indicated in the specifications as "Low Latency").

3. Auto-connection: function Auto Pairing simplifies connection after turning off the TV.

6. Troubleshooting: Sound is choppy, lags, or not transmitted

Even with proper setup, glitches can still occur. Let's look at common errors and how to fix them:

If the sound is not transmitted at all:

• 🔧 Check if your TV model supports Wi-Fi audio streaming (a list of supported devices is usually included in the user manual).
• 🔄 Restart your TV and phone (sometimes resetting the network on the TV helps).
• 📱 Update your TV firmware and phone apps to the latest version.

⚠️ Attention: On TVs Samsung with firmware up to 2020, audio transmission through Smart View may be blocked if the option is enabled in the security settings HDCPTo disable it, go to Settings → General → External Devices → HDCP and select Disabled (This may interfere with some streaming services!).

7. Comparison of methods: which one to choose?

The method you choose depends on your TV, phone, and tasks. Below is a summary table with recommendations:

For most users, the best choice is:

• 📺 If you have Samsung TV and telephone Galaxy → Smart View.
• 🍎 If you have iPhone And LG/Sony TV → AirPlay 2.
• 🖥️ If your TV is old or doesn't have Smart features → Bluetooth transmitter.
• 🎵 If you need minimal latency for music → WoMic or aptX transmitter.
