That is complete nonsense.  You can get a WAV (or RAW) file no matter
what audio compression is used:   

mplayer INPUT.avi -ao pcm -aofile fileout.wav

No, that's what -dumpaudio does.

If you left "-ao pcm" off, it would do exactly the same thing.  Clearly,
dumpaudio is taking priority.  Leave off dumpaudio, and it will output a
wav file.
