Have you ever tried screen mirroring your iPhone to your TV, only to realize there's no sound when screen mirroring iPhone to TV? It's a common issue that can be frustrating, especially when you want to enjoy your favorite movies, videos, or music with proper audio. But don't worry, you're not alone. In this article, I'll explain the possible reasons why screen mirroring sound is not working and provide practical, effective solutions to fix it. Whether you're casting to a Roku, smart TV, or using AirPlay, I've got you covered.
Why Is There No Sound When Screen Mirroring iPhone to TV?
Understanding why screen mirroring sound is not working can help pinpoint the solution. Common reasons for no sound on screen mirroring from iPhone to TV include:
- Wi-Fi Connectivity Issues:
- Network Bandwidth: Screen mirroring is a bandwidth-intensive process. If your Wi-Fi network is not stable or is congested (e.g., many devices are connected), it can cause issues with both video and audio transmission. A dual-band router (2.4 GHz vs. 5 GHz) can help improve stability, as 5 GHz offers higher speeds and lower interference.
- Router Settings: Ensure your router's Quality of Service (QoS) settings are optimized to prioritize the mirroring devices. Some routers may deprioritize bandwidth for devices not directly connected to the network, causing glitches, especially in audio.
- Audio Output Settings:
- Audio Channel Routing: Even though you're mirroring video, your iPhone may still be sending audio to its internal speaker. This can happen if the audio output channel isn't switched automatically. Sometimes, manually selecting the audio output for screen mirroring can help. Control Center > AirPlay > Audio Output allows you to select the TV as the destination for the sound.
- Stereo vs. Surround Sound Settings: Certain TVs or audio systems might have stereo or surround sound settings that need to be adjusted based on the input. If the TV's audio output is set to stereo, it may not process certain audio signals from AirPlay properly.
- Device or App-Specific Problems:
- AirPlay and App Limitations: While AirPlay on iPhone usually transmits both video and sound, some apps, particularly streaming services like Netflix, Hulu, or Disney+, may restrict audio transmission through AirPlay to protect copyrighted content (due to DRM).
- App Sound Toggle: Some third-party apps may have their own settings for audio output. Check the app's settings to see if sound is muted by default or if there's an option to enable sound for screen mirroring.
- TV Settings:
- Audio Sync & Input Conflicts: Some modern TVs automatically try to sync the audio with the video during screen mirroring. If your TV has a "Lip Sync" or "Audio Delay" setting, ensure it's set to auto or off. Some TVs may also prioritize audio from other inputs (like HDMI or external devices) over the screen mirroring connection, leading to audio issues.
- TV Firmware and Compatibility: If your TV is running an outdated firmware or has compatibility issues with newer mirroring technologies, it can block or distort the audio. Check for TV firmware updates that might resolve compatibility issues with screen mirroring.
How to Get Sound on TV When Screen Mirroring from iPhone
If you're facing no sound when casting to TV from iPhone, it can be frustrating, but with the right steps, you can get it working in no time. Here's an enhanced, step-by-step guide to troubleshoot and fix the screen mirror no sound issue, along with some fresh insights to ensure everything works as expected:
Check the Volume Settings
- Volume Sync: Ensure that the volume is up on both your iPhone and TV. Sometimes, even if the TV's volume is up, sound may still be routed incorrectly if the volume output channel is not selected.
- Advanced Audio Output: For TVs with advanced sound systems (like Dolby Atmos or DTS), ensure the TV is configured to handle audio from screen mirroring. For example, certain TVs may need to be set to "Auto" mode to correctly accept the audio from the iPhone.
Check Your Screen Mirroring App
- App-Specific Sound Settings: Some third-party apps like PigeonCast have specific sound options that are enabled by default. If you're using PigeonCast, check if the Sound toggle is turned on in the settings. If you're using other apps, look for similar sound options in the app's menu to ensure the audio is enabled for casting.
- App Updates: Ensure that the mirroring app is up-to-date. Often, updates fix bugs related to sound transmission, ensuring a smoother experience for both audio and video.
Tip: PigeonCast is a free screen mirroring app designed for iPhone-to-TV screen mirroring. If your iPhone screen mirroring is not working, you can give it a try.

Reconnect Your Devices
- Network Check: If sound isn't working, try disconnecting both your iPhone and TV and reconnecting them. Additionally, make sure your devices are connected to the same Wi-Fi network to avoid network configuration issues that may block audio.
- Network Bandwidth Test: If you're using a 5 GHz Wi-Fi network, make sure the router supports the bandwidth needed for smooth mirroring. Use a speed test to ensure the connection is strong enough for both audio and video transmission.
Select Audio Output on iPhone
If the sound is coming from the iPhone but not the TV when mirroring over AirPlay, follow these steps:
- Open Control Center on your iPhone.
- Tap the AirPlay or screen mirroring icon.
- Ensure that TV is selected as the audio output.
- Make sure there are no conflicts in the audio settings in your TV’s audio settings.
Check TV Audio Settings
- Audio Source Input: On your TV, go to the audio settings and ensure it is set to accept audio from the screen mirroring input. Some TVs may require you to manually select the audio source for mirroring.
- Audio Sync: Disable or adjust audio sync settings on your TV to ensure proper lip-sync between audio and video.
Update Your Device Firmware
- Firmware Updates: Always check for software updates for both your iPhone and TV. New updates can resolve known bugs and improve compatibility for screen mirroring.
- Driver Compatibility: On some TVs, specific mirroring apps or AirPlay drivers may need an update to handle the latest sound protocols. Make sure everything is updated to the latest versions.
Try a Wired Connection
- HDMI Adapter: If Wi-Fi-based sound not working on screen mirroring still happens, using a compatible HDMI adapter is an excellent alternative. It bypasses Wi-Fi issues and ensures a stable, direct connection for both audio and video. This solution also prevents audio lag and ensures a high-quality audio output.
- Surround Sound Configuration: For users with home theater systems, using a wired HDMI connection often guarantees stereo or surround sound, providing a richer audio experience.
