Ok!
So after a month and a help of a friend from Canada seems that the user drums are not the problem. This distortion short sound is hear only when start a style with key start.(on the factory audio style too).
If Can somebody who has audya try this at home to let me know is just mine or is a common problem.
Just select a style with audio drums and try intro with key start.It needs a few times becouse it don't happen every time.
Thanks a lot.
