sr0 (or scd0, which is the same device) is "first Scsi (CD-)Rom" device;
that is: the special file for the first SCSI-emulated CD-rom drive.
So as long as you're using "ide-scsi", your CD-rom/writer drive moves
from /dev/hd? to /dev/sr0 (cq /dev/scd0), which has to be readable
for the program to USE it, but to WRITE CD-r(w)'s, it also has to
be writable for the program to send "low-level" commands to it.

By default these devices are only read-write for people/programs,
belonging to the group "cdrom", so you may have to put yourself into
that group (or run the program as root, of course).

sg? are the Scsi Generic devices, which are needed for instance for
the "scan-bus" functions some programs use. In a lot of kernels you
will have to load the "sg" kernel module for them to be usable.
As sg is a low-level interface, ITS default is to be only read-writable
for ROOT.

I don't know KAudioCreator, am using "cdrecord" myself, and I normally
go to root first, to create CD's, as our scripts use too many "root-only"
functionality, for instance setting of real-time priority.
You could setup "sudo" for it, if that's a problem.
