When I start flying from cold and dark, I switch views, and i hear this vacuum cleaner like noise. Any ideas?

Hi Ian, Please sign you full name to posts in this forum, per forum rules, thanks.http://forum.avsim.net/topic/245586-you-must-sign-your-full-real-name-to-posts-to-use-this-forum-posts-without-names-will-be-deleted/Just hit "Q" twice and the problem should clear up. Sometimes things get flooded in FS and this should fix it.* "Q" is the default key command to disable and re-enable the sound, so if you changed this key you will of course want to substitute it with whatever you changed it to.Hope this helps,

Thanks man.
