A PIE sound problem...plz help

[Kiwen]

Hi all thx for reading my thread. i've just made a small level and it seems no problem until i added some ambient sound as my bgm.
When play in editor, when my charactor stop acting(moving, rotating, shooting,etc.), the bgm will go slow, like 50% speed of the original, and the game also become...slow. But when i move the charactor again, everything goes back to normal. i totally have no idea about this, so i wonder if there is anyone met the same problem before or got any explanation about this...thx a lot!

Yeah i did quite a lot...but for the bgm i just used a Play Music Track node, which is connected to the level loaded event. Btw my level loaded nodes are more than one... so i wonder if this has some relationship with my problem... but anyway, i still have no idea about this, especially why this problem disappear after i "act".
