After the application is initialized, this type of object is created and its initialization function is called. The sound can be further added. You can call the corresponding function when playing the video.

Some functions have not been completed, such as obtaining the volume in the configuration, saving the volume settings, and switching the sound.

In addition, audioservicesplaysystemsound (sys_sid); the sound does not know how to control the volume ~~
