      The bug

      The new sound engine introduced in 1.14 sometimes causes sounds in a world to play late when an event happens. If the game lags as a result of high memory usage, then it would also sometimes cause sound to stutter.

      The lag might also cause music to stop completely if the Music slider is turned on. All of these problems did not happen before 1.14.


      The sound delay might be caused by the new sound engine having to load a sound right when a corresponding event happens in a world. If the Music slider is turned on, music would stop completely due to them just being streamed from the corresponding files.

      Once again, these problems did not occur in previous versions.

      Note before reproduction

      The bug might only affect certain sound cards, so please attempt reproduction first before confirming it.

      If successful, please check for the sound card involved by following the procedures below if using a Windows operating system:

      1. Open the Windows start menu, and then search for the "dxdiag" program.
      2. Open the program, and then click on the "Sound" tab.
        The sound card can be seen in the "Device" section.

      Please comment sound cards in the Comments section.
