One can not play audio-cd on freebsd without root access.
No matter what you put in devfs* Tried it since freebsd4*

All,

I was getting exactly this same error following a fresh 8.1 load

the solution was explained in the gnome install FAQ - here is a clip
- the devfs.conf changes fixed the problem.

To figure out which CD/DVD drive you will be using, run the following
command as root:

# camcontrol devlist


Your output will look similar to the following:

<QSI CDRW/DVD SBW-242 UD22>        at scbus1 target 0 lun 0 (cd0,pass0)


The devices in parentheses at the end are important. You must make
sure the /dev entries for those devices are writable by the users
that will be using brasero, totem, rhythmbox, or sound-juicer. In
addition to those devices, /dev/xpt* must also be writable to your
brasero, totem, rhythmbox, and sound-juicer users. The
following /etc/devfs.conf configuration will achieve the desired
results given the above devlist:

perm    cd0     0666
perm    xpt0    0666
perm    pass0   0666

I made those modifications a long time ago without success.

# camcontrol devlist
<PHILIPS DVD8801 GW02>              at scbus1 target 0 lun 0 (pass0,cd0)
<Generic USB SD Reader 1.00>        at scbus2 target 0 lun 0 (pass1,da0)
<Generic USB CF Reader 1.01>        at scbus2 target 0 lun 1 (pass2,da1)

<Generic USB MS Reader 1.03>        at scbus2 target 0 lun 3 (pass4,da3)

# cat /etc/devfs.conf

<snippet>

perm    cd0     0666
perm    acd0    0666
perm    xpt0    0666
