CD audio on Ultra 10

Hi all,

  I have installed potato on Ultra10(Creator). And recently, I set up 
audio drivers, but I have problem with cdaudio that cd player applica-
tion can't play (I try with Gnome CD-player, workman, playcd). 

  I think that is happened caused by ATAPI cdrom device which installed
on Ultra 10, not by audio drivers (cs4231 modules). I tried to log errors
when I run playcd, and get message as below :

---------------------------------------------------------------------------
hdc: packet command error: status=0x51 { DriveReady SeekComplete Error }
hdc: packet command error: error=0x54
ATAPI device hdc:
  Error: Illegal request -- (Sense key=0x05)
  Invalid command operation code -- (asc=0x20, ascq=0x00)
  The failed "Play Audio TrackIndex" packet command was: 
  "48 00 00 00 01 01 00 9e 01 00 00 00 "
---------------------------------------------------------------------------

  I wonder if others have the same problem with me. Any ideas what could
be wrong ? Thanks in advance.
