Sound disables after being played

So, I am experiencing a pretty bad issue. I have added custom sounds to my modded entity. Those sounds are playing fine. But after the sounds get played. Every single possible sound you can think of in minecraft gets disabled apart from the game's songs. So for example, when I break a block, I cant hear it break, when I hit an entity, I cant hear it get hurt. I only hear the minecrafts music. Please help!!
