I have been able to rip from /dev/cdrom linking to /dev/acd0a using
cdda2wav without a problem. I just changed /dev/cdrom to link to
/dev/acd0c and am getting the same error.

I suspect that somehow cdparanoia/Linux binaries are expecting the cdrom
device to be of a different form than what that device looks like under
FreeBSD. Which gets us back to the question of what a "cooked ioctl" is
and how one could perhaps create a device entry for a CDROM under
FreeBSD that would meet the cooked ioctl test.

Thanks in advance,
