very big sound problemWhen I look out the virtual cockpit, I can not hear any engine sound.I turn to the direction of the cockpit wall / cab, I hear the sound.The same with the exterior views. I look forward on by plane, I hear from the side and rear, not the engines.work only in the window seat view you can hear the engine sound problems.All other sounds are there.I deleted the 737NGX ever installed ... and again without success.I need help!
