strange sound when you change views

[stabell 0]

Hello!I don't know if this is a PMDG only matter, but when I change views, from cockpit to outside and back to cockpit, I get double sound. It is two sets of sounds on top of eachother, resulting in a "flanger" sound. This is even more appearent in outside view, where the engine sounds get strange. Does anybody know how to get around this, or is it just me?Regards,tore Stabell Kul
