To listen to sound (["Ogg"], ?"MP3", .au files, !["CDs"] etc) on your sound card, you need to:

You can install too eg [ Sound/Audio apps] or [ wiki:?MAD apps using], 'xfreecd' (music CD playing software), 'mp3blaster' (full-screen console mp3-player), or 'saytime' (if you have no CD drive and no !["MP3s"]). Try to run them as root (it should work). With Debian, ordinary users lack permission to read the CD drive and write to the audio device (usually /dev/dsp), and they probably can't use these programs (yet; see next paragraph).
