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.

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.

If you think things can't get worse it's probably only
because you lack sufficient imagination.
