When a CD-ROM device is allocated, the user is queried whether or not to mount the CD-ROM.
If the CD contains a file system, answer yes to automatically mount the CD.
If the CD is an audio CD, answer no.
When the answer is no, if an audio action is specified in rmmount.conf, the audio action executes. By default, no audio action is specified.
To play an audio CD, the user must allocate both the audio and CD-ROM devices. The user can optionally manually invoke an audioplayer application after allocating the device. See "To Play an Audio CD" for how the security administrator can set up an audio action for users.
