iirc, you need to use special ioctls to read cd audio data and so dd doesn't work at
all for audio cds.

whilst we are on the subject though, a cdripping discussion came up a while ago WRT
accurate ripping of cds. at the time, i tried ripping an audio cd with cdrdao but
using the raw modes to see if the latent hardware r/w offsets were ignored in that
case. when i burned and ripped the resulting cdr back again, the image was indeed correctly aligned.

anyone else noticed this?

cheers,
pete.
