Hi friends! Just for clarification, please provide what speakers or headset you are using. For voice chat issues, we recommend these connection steps, as it may be an issue with the VoiP. You could also try verifying your game files (Depending if you purchased the game through Steam or Uplay). These PC steps may also help.
If that does not help, please make a ticket with your msinfo and dxdiag files attached. Thanks!
