I don't know anything about how "K3B, DeVeDe, ManDVD, Kdenllive" encode audio.

FFmpeg's AC3 encoder was changed to expect float (instead of int16). The new
encoder is faster on typical hardware (and at least not worse in quality). To
get the original behaviour, the programs have to open "ac3_fixed" instead of
"ac3". (And yes, I know I've claimed in the past we do not break ABI,)
