Panel wav files

This panel contains 70 or so wav files, and they are WAY too loud. Lowering 'cockpit' volume in FS does not change them.
Windows 98 had a device that I used to vary the volume of wav files, but I don't find it in Vista (Home Premium).
Perhaps it's renamed to ...?
Anything in FS SDK's, manipulate wav files?
I downloaded a couple of 'free' sound programs, but for some reason they wouldn't save the lowered setting.
Perhaps it was waiting for me to donate
