sequence中调用play rate track会改变音频播放速度，而音频本不该被影响
play rate track in sequence will change the speed of the audio, which should not be affected
Set the Sequencer.Audio.MaxDesyncTolerance CVar to zero to work around this until it is fixed in a future version. You can add it to the:
[ConsoleVariables]
Sequencer.Audio.MaxDesyncTolerance=0
Section of your game’s DefaultEngine.ini to have it automatically be applied. This feature was added to handle long game replays that used long streamed audio clips, so disabling it is unlikely to affect your project.
