This chapter contains programs involved with audio file manipulation; that is to say playing, recording, ripping and the other common things which people want to do. To use much of this software, you will require either the kernel sound drivers installed, or ALSA-0.9.6 installed. Note that in the 2.5 kernel development tree, the old drivers are being replaced with ALSA and so when the stable 2.6 series arrives; most people will be using it by default.
