Wilco Airbus Series volume 1 problem

Hi guys,after a long time I´ve installed the Wilco Airbus serioes voulme 1 yesterday and patched it with the latest SP 1e. I haven´t flown the plane befpore that patch and I´m havein now some sound problem: In the view directly to the front I can´t near any engine sounds. In every other angle and outside it´s working all right. Does someone have a soultion on that?EDIT: Solved! The speakers weren´t in Stereo mode. Now ít´s working again. And I see how badly coded these planes are! Why did I buy them?
