Hello, i had the same issue, try this:

  1. Open the game without internet connection.
  2. Once u are in game u should still hearing sound, if it does, start internet connection.
  3. Open matchmaking and wait until u got online. After that u should keep hearing.
    I hope u can solve it with this.
