[Icecast] ezstream/madplay: problem with decoding

So here's the story: I thought I would explore further features of the ezstream,
including its ability to reencode various input types (e.g. ogg, mp3, flac) on
the fly into one type of stream (ezstream_reencode_mp3.xml config). It works
wonderfully except for one problem: the decoding of mp3s results in a steady
stream of noise (i.e. the source is not distinguishable among the noise). Using
the the standard config (ezstream_mp3.xml), everything works fine. So I think I
can conclude it is not a problem with my build of ezstream, but it may have
something to do with either the madplay build or the madplay settings. Sadly, I
have little experience with encoding/decoding and/or the settings involved but
wading through the man page, they seem to be appropriate:

madplay -b 16 -R 44100 -S -o raw:- "@T@"

Is there anyone that can shed any light on this?
