Don't we just love software that gives half-error messages?  Just how
difficult would it have been for the author to have identified just what

Is your user a member of the audio group?  I do CD ripping sometimes, and
the three groups acm is a member of which seem relevant are audio, cdrom,
and cdrw.

Running ripping as root isn't ideal.
