I think you are a tad confused as to what ATAPICAM does.  It does in 
fact provide access to ATAPI drives via the CAM layer, but in the 
case of cdda2wav it can speak to ATAPI drives natively, it doesn't 
require ATAPICAM to speak to them.  IDE optical drives were /dev/acdX 
in 4.x just like they are in 5.x and 6.x

There is a bug in the command, since 5.x the correct device name 
should not be /dev/acd0a, but /dev/acd0

The following PR contains the patch to fix the outdated device name in 
the handbook.

# cdda2wav -D /dev/acd0 -t 7
cdrom device (/dev/acd0) is not of type generic SCSI. Setting 
interface to cooked_ioctl.
