Same result on my notebook (HP nx6320) and this is not a surprise. The
"mixer" command does not show a "cd" input, meaning that there is no
input port for the analog audio output of the CD drive (if any). The
"status audio" arguments instructs cdcontrol to inquire the drive, not
the audio device.

NetBSD's "cdplay" supports digital transfer mode since version 4.0.
Perhaps this feature could be implemented on cdcontrol.
