Can't hear the sound after I am into the game

Hi All,

I am a new here and my English ability is very limited.
I got a strange issue. When I play AoE DE. It works in the first several times.
But someday I can’t here the sound(the horn) when I got attack. And I also found that there is no weapons sound. But when I select the accessibility, such as Menu, Chat, Game, I can here the voice. The music volume and the sound volume are in the high.
I also can here the sound of the entry video.
I did remove and install AoE, I also reset my Windows 10. But there is still no sound effect when I got attack or the introduce in every next unit.
Could someone can help me to resolve it? Thanks a lot!!!
