You’re ready to stream a movie, present at a meeting, or share a video with friends, but when you mirror your screen to the TV, the audio stays behind. This common frustration happens because screen mirroring doesn’t always transmit sound automatically. The good news: you can absolutely screen mirror with audio on iPhones, Android devices, Windows PCs, and Macs using the right settings or equipment. Whether you want sound playing through your TV, external speakers, or a Bluetooth device, the solution is within reach.
This guide covers every proven method to mirror your screen with audio, from wireless options like AirPlay and Google Cast to wired connections using HDMI. You’ll find step-by-step instructions, device-specific tips, and user-verified workarounds to ensure your content plays with full sound every time.
Wireless Screen Mirroring with Audio
Most wireless protocols support audio transmission, but you need to configure them correctly. Here’s how to get sound working with popular wireless methods.
AirPlay Screen Mirroring on Apple Devices
Apple devices use AirPlay to mirror both video and audio to Apple TV or AirPlay-compatible smart TVs.

Full screen mirroring doesn’t always include system audio on Android devices.
How to enable audio during mirroring:
- Pull down Quick Settings and tap Cast or Smart View (Samsung)
- Look for “Cast screen/audio” or similar option
- Enable it before connecting if available
Some Android devices only support audio from specific apps, not system-wide sounds. For reliable audio, use app-based casting instead of full screen mirroring.
Windows PC Audio Management
Miracast sends full audio to your display, but you can redirect it afterward.
Change audio output after mirroring:
- Press Win + K to connect via Miracast
- Right-click the sound icon in your taskbar
- Go to Sounds, then Playback tab
- Select your preferred speaker as the default device
This lets you switch from TV speakers to headphones or external audio systems.
