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.

Yes, that explains what happens on my notebook and corresponds to
what the Handbook says:
If all goes well, you should now have a functioning sound card. If your
CD-ROM or DVD-ROM drive's audio-out pins are properly connected to your
sound card, you can put a CD in the drive and play it with
cdcontrol(1):
% cdcontrol -f /dev/acd0 play 1

Indeed, both the 'mixer' command and the (much more comfortable) 'rexima'
port show only 5 mixer devices:
Mixer vol is currently set to 12:12
Mixer pcm is currently set to 30:30
Mixer speaker is currently set to 8:8
Mixer mic is currently set to 0:0
Mixer rec is currently set to 0:0

There is no 'cd' mixer device, and the only mixer device file on
this notebook is '/dev/mixer0'.

But this does not explain why mplayer, in contrast with vlc, refuses
to play the CD, does it ?

No, doesn't. On my notebook I'm able to play audio CDs with mplayer
using either your command syntax, "mplayer cdda://1//dev/acd0" and
with the simpler one "mplayer cdda://1". The audio is bad, however
(has periodic interruptions). This is certainly a problem in mplayer
since GXine works fine.

What is the meaning and reason of the above FAILURE lines ?
2 identical lines with the GENERIC kernel,
1 single line, if I add 'device atapicam'.

I doubt atapican has something to do with your problem but you can
check this by booting with GENERIC and issue "kldload atapicam" later.
I did it here and had no additional problem with mplayer besides the
bumpy audio output. I guess your problem is in the CD drive. I suggest
you to do three things:

1. Try to insert the CD and wait until it stops pinning before
starting mplayer. Some drives are a bit lazy on media recognition.

2. Run "truss mplayer ..." and look for error messages.

3. Attempt to use a different player. Xine and/or one of its alternate
front-ends like GXine or Kaffeine are good choices.

because you lack sufficient imagination.
