The problem might very well come from our faad2 decoder plugin.
This plugin forces the FAAD_FMT_FLOAT mode for the libfaad2 output and I'm 
pretty sure this isn't supported in the fixed point version of libfaad2.
You'll likely have to tweak modules/codec/faad.c to use FAAD_FMT_16BIT and 
make the appropriate changes so VLC knows it's dealing with 16bits integers 
instead of floats.
