Odd sound occurs at Level-D 767

Recently, I've purchased TSS's 767 GE sound to use it as a replacement sound for Level-D 767.

After install, i started flight sim and loaded Level-D 767.

Unfortunately, the engine sound sounds very odd.Just like a buzzing, scratchy, blare sound

I wasn't able to find any difference on replaced sound compared to default level-d sound. Of course I tried to configure the sound settings, but it wasn't a solution for problem.And when I replaced the sound file to other aircraft, It just works perfectly without problem :(

So it seems like a problem only occurs on Level-D 767, but I couldn't fimd any solution for it on any flight sim forum.

I'll be a great help for me if you guys help me to solve this problem !
