weird sound problem : a bug?

Unity Engine
1

Hello folks:

I had a working FPS type project. But after I added footstep function sounds from the FPS tutorial(http://unity3d.com/support/resources/tutorials/fpstutorial), the sounds in my project sound somewhat muffled and, especially, the door sounds sound raspy.
Funny thing is that the raspy noise remains even when the door sounds are turned off,

//audio.PlayOneShot(doorSnd);

footstep function is commented out, and footstep sounds are deleted from the project.
Now whenever doors are opend/closed I hear only that raspy noise. Sounds attached to other objects don’t trigger the noise. Closing relaunching the project didn’t help. It looks like the noise resides in a certain cache. Did anyone experienced a similar case? Could this be a bug in engine?

Thax for reading this, and I would appreciate any comment.

That sounds very weird :frowning: Are you getting any script compile errors?

No. Like I said the project used to be working all right untill I added the sounds.
