NAME
     cdplay -- compact disc player

SYNOPSIS
     cdplay [-a audio device] [-f device] [command ...]

DESCRIPTION
     cdplay is a program to control the audio features of a CD-ROM drive.

     If no command is given, then cdplay enters interactive mode, reading commands from the stan-
     dard input.

     The following options are available:

     -a audio device
	     Specify the audio device to use.  Used only in digital transfer mode.  If not speci-
	     fied, the environment variables AUDIODEV and SPEAKER will be tried (in this order)
	     to find the device; as a last resort, /dev/sound will be used.  If the ``-a'' com-
	     mand line option is used, or the CDPLAY_DIGITAL environment variable is present,
	     digital transfer mode is switched on automatically.

     -f device
	     Specify the control device to use.  Both absolute paths and paths relative to /dev
	     are accepted.  The suffix 'c' (or 'd' on some architectures, see disklabel(8) for
	     details) is added to the device name if needed.  If the device not specified, the
	     environment variables MUSIC_CD, CD_DRIVE, DISC and CDPLAY will be tried (in this
	     order) to find the device.

     The available commands are listed below.  Only as many characters as are required to
     uniquely identify a command need be specified.  The word play can be omitted in all cases.

     play [first_track [last_track]]
		 Play from track first_track to track last_track.  The first track has number 1.

     play [start_m:start_s.start_f [end_m:end_s.end_f]]
		 Play from the absolute address (MSF) defined by start_m in minutes, start_s, in
		 seconds and start_f (frame number) to the absolute address defined by end_m in
		 minutes, end_s, in seconds and end_f (frame number).  Minutes are in the range
		 0-99.	Seconds are in the range 0-59.	Frame numbers are in the range 0-74.

     play [#start_block [length]]
		 Play starting from the logical block start_block using length logical blocks.

     next	 Skip to the next track.

     prev	 Skip to the previous track.

     pause	 Stop playing.	Do not stop the disc.

     resume	 Resume playing.  Used after the pause command.

     shuffle	 Select shuffle play.  Only valid in interactive mode.

     single [track]
		 Pick a single track and play it repeatedly.  If a track argument is not given
		 the single command will shut shuffle mode off and play the disc normally.  Only
		 valid in interactive mode.

     skip	 Skip to another track.  Only valid when shuffle play is selected.

     stop	 Stop the disc.

     eject	 Eject the disc.

     close	 Inject the disc.

     volume left_channel right_channel
		 Set the volume of left channel to left_channel and the volume of right channel
		 to right_channel.  Allowed values are in the range 0-255.

     volume value
		 Set the volume of both left channel right channel to value.  Allowed values are
		 in the range 0-255.

     volume mute
		 Turn the sound off.

     volume mono

     info	 Print the table of contents.

     status	 Display the current audio, media and volume status.

     digital n	 Turn on digital transfer mode.  In this mode, cdplay reads digital data from
		 disc and sends it to an audio device.	A SCSI or ATAPI CD-ROM is required; and
		 the audio device must support CD audio format (44100 Hz sampling rate, 16-bit
		 stereo samples).  Audio data are read and written in groups of n frames (5 by
		 default, or 1/15 seconds).

     analog	 Switch from digital back to analog mode.

     help	 Print the list of available commands.

     reset	 Perform the hardware reset of the device.

     set msf	 Set minute-second-frame ioctl mode (default).

     set lba	 Set LBA ioctl mode.

     quit	 Quit the program.
