Mist, darkice bringt bei Debian von Natur aus keine Ünterstützung für mp3 mit (und das ist lizenzmäßig auch gut so).
Das musste ich erstmal für meinen Hausgebrauch ändern :-)

Description: Live audio streamer
DarkIce is an IceCast, IceCast2 and ShoutCast live audio streamer. It
takes audio input from a sound card, encodes it into mp3 and/or Ogg
Vorbis, and sends the mp3 stream to one or more IceCast and/or
ShoutCast servers, the Ogg Vorbis stream to one or more IceCast2
servers. DarkIce uses lame as a shared object as its mp3 encoder, and
the Ogg Vorbis as its Ogg Vorbis encoder.
