Name

       hcdplay — Control autonomous CDDA playback using Linux CDROM ioctls

Syntax

       hcdplay [-EPRSTs] [-D device] [-p first-track [last-track]]

Description

       CD-DA  discs  in  CD-ROM  drives  can  either  be  played back using Digital Audio Extraction (DAE) where
       software requests sector by sector, or by using the drive's autonomous playback  functions,  whereby  the
       drive's  firmware  will  do  the  sector  reading.  Software  is only required for a few control codes to
       initiate or terminate playback. (If the drive possesses extra buttons besides the eject function, such as
       the Sony CDU5221, Autonomous Playback can even be controlled using that method as well.)

       With  this  autonomous play mode, the drive can/will output sound using a variety of methods. Common ones
       are a 3.5mm headphone jack and a 4-pin Analog  Audio  connector  that  is  supposed  to  be  connected  a
       soundcard.  These  are  often  lacking  nowadays,  especially  external drives, slimline drives, and even
       internal 5.25" SATA drives. As such, these drives often do not even  implement  the  Autonomous  Playback
       functions anymore (the particular ATA commands are ignored).

Options

       -D, --device device
              The path to the CD-ROM device node. Defaults to /dev/sr0.

       -E, --eject
              Request that the drive be ejected.

       -P, --pause
              Pause playback. This can only be issued if the CD-ROM drive is in the Playing state.

       -R, --resume
              Resume playback. This can only be issued if the CD-ROM drive is in the Paused state.

       -S, --stop
              Stop playback.

       -T, --toc
              Print part of the disc's table of contents (TOC).

       -p, --play [first-track [last-track]]
              Start  playback  of  first-track and play until last-track. If no first track is specified, starts
              from 1. If no last track is specified, it will play until the end of the disc.

       -s, --start
              Start playback.
