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.

I don't recall having that problem with the Turboprop Simulations - Lockheed C-130 Hercules Sound Pack. I do think it's better than the default C-130 Sound though.
I'm currently reinstalling FSX and all my addons, so I'll reinstall the sound pack (it is down the bottom of the list, but I'll bump it up) and see if it happens to me too. ;)
