Plextor PX-870A drives

I have a couple of Plextor PX-870A drives in different machines
(see below) that I'm trying to use with atapicam.  The drives mostly
work (booting, reading data, etc.) but for whatever reason neither
of them will play audio CDs using the "cdcontrol play" command.
They just sit there.  The drives never spin up.  There are no obvious
errors.  I've tried multiple types of CDs (CD-Rs that I burn and
commercial audio CDs).  I can burn audio CDs using cdrecord that
play in other drives, they just won't play in these drives.  And while
"cdcontrol info" will show me what tracks are on a CD it just
won't play them.  I have a Plextor PX-850A that works fine.  Is
there something incompatible with PX-870A drives and FreeBSD?  I
can provide more info if needed.
