Audio sync issues can be adjusted in the app settings. Go to Settings > Audio/Video and use the audio delay adjustment slider. Start with small increments (±50ms) until the sync is perfect. Network latency can also affect sync - try using a wired connection for best results.

• Check your device's volume levels and mute settings
• Verify the receiving device's audio output settings
• Try switching audio quality settings in the app
