I purchased the Turboprop Simulations - Lockheed C-130 Hercules Sound Pack FSX and installed it.  My complaint is that I still only get cockpit engine noise when I scan either all the way to the left or right.  Respectively, I here the left engines when scanned to the left and right engine noise when scanned to the right.  I get no engine sounds when my view is straight ahead  or ~ 45 degrees left or right.   This is the same for all cockpit views.  I do get engine sounds when viewing the cargo bay.  This is the same exact problem I was having before I installed the Turboprop Simulations - Lockheed C-130 Hercules Sound Pack FSX.   The sound works fine with all the exterior views.  Any suggestions here or people with similar problems?

Thanks for your help in advance.
