Equalizer doesn't work with all audio types

As pointed out in here: http://forum.videolan.org/viewtopic.php?f=14&t=36679&st=0&sk=t&sd=a&start=15#p158928

There are some audio files which won't work with VLC equalizer (equalizer error: rate not supported, main warning: no audio filter module matching "equalizer" could be loaded). I tested with Win32 vlc-1.0.0-git-20080908-0006.

Sample file: http://www.raiska.com/vlc/eq_audio.wav
