Hi Lou.

What issues are you having that are "new?"  :-?
When I first load the CS 727 into FSX, the sounds don't work (mainly the altitude alert and the cabin announcements), so I have to reload the aircraft to get them working. <- This is NOT new!
If I change the weather from Fair Weather or Clear skies (clears all weather) to anything else, the sound disappears again. The same applies if I use AS2012 (which I use for real world weather generation). <- This is new to me. I never noticed this until I checked with the problems that CSdoesnotwork mentioned in their post. That means it either didn't used to happen to me. OR. I had attributed it to my "forgetting" to reload the 727 into FSX, when in actual fact I had reloaded it into FSX.
