Remarks

Beginning with Windows Vista, CDROM class drivers do not use this IOCTL. Prior to Windows Vista, this IOCTL was used for audio playback on older CD-ROM drives that supported direct audio output in hardware.

Client applications should use the Media Control Interface (MCI) API rather than issuing this IOCTL.
