Screen mirroring has picture but no sound

Apple’s AirPlay troubleshooting guidance specifically says to check that both the iOS device or Mac and the television or receiver are turned up and not muted when video is visible without audio. A phone’s volume buttons may control a different output depending on the current route, so look at the on-screen volume/mute controls on both endpoints rather than assuming one slider governs the whole chain. If the TV feeds a receiver or soundbar, that device may own the final volume.

1. Raise the sender’s media volume and confirm it is not muted while the mirrored video is playing.

   If audio begins, the sender-side level or mute was the immediate issue.

   If that does not help: If silent, check the TV or receiver separately; do not repeatedly raise volume to unsafe levels.

2. Raise the TV/receiver volume and check its mute indicator while the same video continues.

   A change here identifies the playback endpoint’s level as relevant.

   If that does not help: If no sound, determine which device is selected as the TV’s audio output.

3. If a soundbar or AV receiver is intentionally used, check its own volume, input, and standby state according to its manual.

   This tests the actual final speaker path rather than the TV’s internal speakers.

   If that does not help: If the TV’s built-in speakers are selected but an external system is expected, reconnect the intended output using the device manuals.

A TV program playing from a built-in app and a mirrored phone video do not use the same audio path. Test a second ordinary video or audio item from the phone, then play something in a TV app. If TV apps have sound but all mirrored content is silent, focus on the sender-to-receiver route. If TV apps are also silent, the problem is broader TV/external-audio troubleshooting and should not be attributed to mirroring. If only one app is silent, check its own audio controls and support documentation.

1. Play a second short video or local recording from the phone using the same mirror session.

   If it has audio, the first app/title is the narrower suspect.

   If that does not help: If every mirrored item is silent, continue with route and receiver checks.

2. Play a TV built-in app through the same speakers or soundbar.

   Sound here shows that the TV’s general output path can work even though mirroring remains silent.

   If that does not help: Silence here too indicates a TV or external-audio issue beyond the phone mirror session.

3. If possible, compare a different compatible sender or receiver without changing other settings.

   A result that follows one phone, app, or TV helps isolate the responsible endpoint.

   If that does not help: If no second device is available, record that limitation rather than treating it as proof of a hardware fault.

AirPlay or a device’s wireless display feature may direct audio to a receiver or external system. Confirm that the intended TV/receiver is still selected and that headphones, a Bluetooth speaker, another AirPlay destination, or a previously paired accessory has not taken the audio route. Menu names differ by phone and OS; use the operating system’s current playback-output control rather than assuming a fixed settings path. Also distinguish full-screen mirroring from an app’s direct playback: a video app may hand playback to the TV in a way that changes which device controls audio.

1. Open the sender’s current audio-output/destination control and confirm the active destination matches the TV or receiver showing the picture.

   If audio was routed elsewhere, selecting the intended supported destination may restore sound.

   If that does not help: If the TV is selected but remains silent, continue with endpoint volume and app comparisons.

2. Stop the session, disconnect unused Bluetooth/audio destinations temporarily, and start a fresh mirror session.

   If sound returns, the prior route or session state likely mattered.

   If that does not help: If not, restore any accessories you need and contact the device maker with the test results.

3. Try the app’s own Cast/AirPlay playback control if available and note whether sound differs from full-screen mirroring.

   Different outcomes indicate that app playback and screen mirroring use different routes.

   If that does not help: Use the supported mode that works and report the mode-specific failure to the platform/app provider.

When a TV is connected to a soundbar or AV receiver, hearing a mirrored picture without sound does not automatically mean the phone failed to send audio. The TV may be set to an external audio output that is off, on the wrong input, or temporarily unavailable. Conversely, the TV’s internal speakers may be muted because audio is expected over HDMI ARC/eARC or another connection. Check which system normally plays TV sound and verify that system with an ordinary TV app before changing cables, HDMI control settings, or advanced audio formats. Exact labels and behavior vary by model.

If the sender and TV/receiver are unmuted, the selected destination is correct, TV apps have sound, and every supported mirrored source remains silent, collect the phone model/OS, receiver model/software, mirroring method, app/source tested, and whether external speakers are used. Contact the platform or TV maker. If one streaming app alone is silent, contact that service first. Avoid factory resets and audio-format changes until support identifies a model-specific reason; those steps can erase setup or change unrelated playback behavior.

Why can I see my iPhone on AirPlay but hear no sound?

Check mute and volume on both the iPhone and TV or receiver, then verify the selected playback destination. Apple lists both endpoints’ volume as a first check.

Why is only one mirrored app silent?

The app may handle audio or playback differently. Compare another item and use the app’s supported TV playback route; contact the app provider if only that app fails.

TV apps have sound but phone mirroring does not. What does that mean?

It narrows the issue toward the sender, mirroring session, app, or wireless audio route rather than the TV’s entire speaker system.
