I think I know what it means. The easiest way to think about it is probably to realize that in order to play audio, the bits recorded on the CD have to make it to the digital-analog converter somehow. If there's no direct line from the CD drive to the sound card (as we were discussing in the trimmed text), then that data has to be moved around in software. Some tool is needed to extract the audio data from the CD drive, and some tool is needed to send those off to the sound card; these tools can be the same, but need not be. I tend to use cdparanoia for the first step, and the play(1) utility provided by audio/sox for the second step, leaving the bits around on my (sizable) hard drive for later use. It sounds like xmms and amarok can combine the two steps into one, without leaving the bits on disk as an intermediate; I'm not sure offhand whether there are more lightweight utilities that can also do so. -Ben
