Hello guys, I recently got into the business of making videos for FSX. When I'm recording with Fraps I can't hear the sound of the engines of the PMDG 737-800 NGX. Please watch this video in HD and see, their were lots of add-ons used.

I added some music because you couldn't hear the sound, just too make it a little bit better. I know that you need to configure something in the PMDG sound settings but I don't know what. If anyone has any thoughts on how to fix this please help.

P.S - Read the description to see all the add-ons used, and lastly enjoy the video.
