You cannot mount audio CDs.

The important lines from your system log are:

acd0: FAILURE - READ_BIG ILLEGAL REQUEST asc=0x64 ascq=0x00 
SCSI status: Check Condition
SCSI sense: ILLEGAL REQUEST asc:64,0 (Illegal mode for this track)

This seems to indicate that the CD cannot be read. Can it be read
with a different drive? Maybe the drive is faulty. Or the media
is. Can you check the media in a "hardware CD player"?

First of all, HAL seems to be interfering. To check, make sure HAL
is not running, then do "cdcontrol play 1". Have the "mixer" program
push all volumes up.

In how far does mplayer "see a drive"?

Does the drive have a phones connector at the front? Does it maybe
play from there? Playing audio CDs is a feature of drives that does
not neccessarily need CPU / system attention (except for starting
the playback by a drive command).

Are you accessing the drive by ATAPI or ATAPICAM?

So no problem on this side.
