This could go in the existing Nimitz thread, but since that's getting long and some folks may have stopped reading it -- who really want to know about this fix -- I'm starting a tiny, independent thread.
If you're using Javier's Nimitz -- probably my favorite add-on of the year so far -- do yourself a favor and install the tiny sound files provided by Wingmate here: http://www.sim-outhouse.com/sohforums/showpost.php?p=203074&postcount=342. I thought I did this, and kept wondering why I still wasn't getting any sounds when the JBD went up for cat launches. Checked, and I hadn't installed the fix after all; must have just looked at it and maybe got interrupted. In any case, do it. It's easy and, not only will you get your JBD sound back, but more importantly you will get the big catapault "woosh" sound back that you forgot about from the Acceleration carrier...
