           Summary: inconsistent handling of Audio-CDs
           Product: Wine
           Version: 1.1.32
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: ntdll
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: hoehle at users.sourceforge.net


mci "open cdaudio" fails on pure Audio CDs, but the bug is not within MCI
rather than in volume management or kernel32/ntdll (the MCI calls
GetDriveTypeW).

Case A) When an audio-only CD is inserted before Wine is started, it creates
the link
dosdevices/d:: -> /dev/scd0
and in system.reg:
[Software\\Wine\\Drives]
"d:"="cdrom"
mciSendString "open cdaudio" fails (MCIERR bad device) because GetDriveTypeW
does not return a CDROM type. It would succeed on MS-Windows.

Wine creates the additional link d: -> /media/cdrom0 only when using a
data-only CD-ROM or a mixed data + audio CD.
In the latter case, mciSendString "open cdaudio" succeeds.

Conversely, an existing dosdevices/d:: link causes dosdevices/d: to be removed
when Wine starts with a pure Audio-CD in the drive.

For consistency, you should have dosdevices/d:: point to your CD-ROM device,
because of another bug in volume management:
 MCI "open e:\ type cdaudio" fails, while
 open d:\ succeeds
 even when E: is the CD-ROM!


Case B) Defining a CD-ROM myself (or like Wine did years ago?) using:
dosdevices/d: -> /media/cdrom
  (which is in turn a link to /media/cdrom0 in Ubuntu)
dosdevices/d:: does not exist.
[Software\\Wine\\Drives]
"d:"="cdrom"
mciSendString "open cdaudio" succeeds.
"play cdaudio" causes the drive to spin, but is sometimes returned with
MCIERR_HARDWARE.
AoE2 sends slightly different MCI commands and manages to play the CD.
Even Crazy Machines successfully plays the audio CD with this setup.

Using Ubuntu Intrepid.
