Symptoms
- You can hear the other side but they can't hear you
- Neither side can hear anything during two-way talk
- Audio cuts in and out or has a long delay
- Feature worked before but stopped recently
Likely causes
- CommonMicrophone muted or phone app missing microphone permissionThe phone's OS may block microphone access for the app if permission was denied.
- CommonCamera speaker volume turned down or muted in-appSome apps have a separate volume slider for the camera's speaker output.
- PossibleWeak Wi-Fi signal causing audio dropouts or delayTwo-way audio is sensitive to latency and can break up badly on a weak connection.
- PossiblePhone's own microphone or speaker issue unrelated to the cameraA phone case covering the mic, or a phone hardware issue, can look like a camera problem.
- Less commonCamera's microphone or speaker hardware failureOutdoor exposure over time can damage the small speaker or mic components.
What to do
- Check your phone's app permissions and confirm microphone access is allowed for the camera app.
- Check the in-app volume and mute settings for both the camera's mic and speaker.
- Test two-way talk on a different phone to rule out a phone-specific issue.
- Improve Wi-Fi signal strength at the camera if it's marked weak.
- Restart both the app and the camera.
- Test the phone's microphone and speaker with another app to confirm the phone itself works.
- If audio still fails on multiple phones and networks, the camera's mic or speaker may be at fault.
When to call a pro
If the camera's speaker or microphone hardware has failed, contact the manufacturer since this generally isn't user-repairable.
