# Troubleshooting Voice And Video Calls

If you're experiencing issues with voice or video calls in Junovy Talk, this guide will help you diagnose and resolve common problems.

## Before You Start

Ensure you have:

- A stable internet connection (wired connections are recommended for best results)
  - An up-to-date web browser (Chrome, Firefox, Edge, or Safari)
  - Working microphone and camera (if using video)
  - Granted browser permissions for camera and microphone

## Common Issues and Solutions

### No Audio - Others Can't Hear Me

1. **Check microphone permissions**: Ensure your browser has permission to access your microphone
   - Look for a camera/microphone icon in your browser's address bar
   - Click it to review and grant permissions

2. **Select the correct microphone**:

- Click "Check devices" in App Settings

- Ensure the correct microphone is selected

3. **Check if you're muted**:

- Look at the microphone icon in the call controls

- Press **M** to toggle mute

4. **Test your microphone**:

- Use the device preview before joining a call

- Speak and check if the audio level indicator responds

### No Audio - I Can't Hear Others

1. **Check your speakers/headphones**:
   - Ensure your audio output device is connected and working
   - Test with other applications to confirm

2. **Check browser audio permissions**:

- Ensure the browser tab isn't muted

- Check your system audio settings

3. **Select the correct output device**:

- Click "Check devices" in App Settings

- Verify the correct audio output is selected

### Video Not Working

1. **Check camera permissions**:
   - Ensure your browser has permission to access your camera
   - Some browsers show a camera icon in the address bar

2. **Verify camera selection**:

- If you have multiple cameras, ensure the correct one is selected

- Use "Check devices" in App Settings to test

3. **Check if camera is in use**:

- Another application may be using your camera

- Close other video applications and try again

4. **Restart your browser**:

- Sometimes a browser restart resolves camera issues

### Poor Call Quality

1. **Check your internet connection**:
   - Run a speed test to verify your connection
   - A stable connection of at least 2 Mbps is recommended

2. **Close unnecessary applications**:

- Background applications may consume bandwidth

- Close streaming services or large downloads

3. **Use a wired connection**:

- Wi-Fi can be unstable; try connecting via ethernet

4. **Reduce video quality**:

- Turn off your camera if you only need audio

- This reduces bandwidth requirements

5. **Check network restrictions**:

- Some networks may block video calling traffic

- Try using a different network if available

### Call Keeps Disconnecting

1. **Check internet stability**:
   - Intermittent connections cause disconnections
   - Test your connection with other services

2. **Update your browser**:

- Outdated browsers may have compatibility issues

- Ensure you're using the latest version

3. **Disable VPN**:

- VPN connections can sometimes interfere with calls

- Try disconnecting your VPN temporarily

### Screen Sharing Not Working

1. **Grant screen sharing permissions**:
   - Your browser needs permission to share your screen
   - On macOS, check System Preferences > Security & Privacy > Screen Recording

2. **Use a supported browser**:

- Screen sharing works best on Chrome and Firefox

- Safari has limited screen sharing capabilities

## Testing Your Setup

Use the "Check devices" button in App Settings to:

- Preview your camera
  - Test your microphone
  - Verify your audio output
