A. 1. Check Volume Settings: Ensure that your device's volume is turned up and not muted. Also, check the in-app volume settings during the video chat.
2. Microphone Permissions: Go to Settings > DingTalk and ensure that microphone access is enabled. If it is disabled, enable it and restart the app.
3. Restart the Call: Sometimes, simply hanging up and rejoining the call can resolve audio issues.
B. 4. Use Headphones: If the audio issues persist, try using wired or Bluetooth headphones to see if that improves the audio quality.
