rplayd - rplay sound server

rplayd  is  the sound server for the rplay audio system.  The server listens for requests to play, pause,
       continue, and stop sounds using both the RPLAY and RPTP protocols.  Normally RPLAY requests are  received
       on  port 5555/udp and RPTP on 5556/tcp.  (Older ports 55555/udp and 55556/tcp are also supported)  Access
       to the server is restricted using the rplay.hosts file.

       rplayd can be started during the system boot process, via inetd, or by individual users.  root access may
       be required depending on audio device permissions.

       In most causes rplayd will play sounds that are available on the local disk.  However, rplayd can be sent
       sounds via the network and rplayd can also contact other rplayds to share sound files.  The index of  all
       the  local sound files is stored in rplay.conf and remote rplayds are specified in rplay.servers.  Sounds
       received from other rplayds will be stored in a cache directory normally  located  in  /tmp/.rplay-cache.
       Cache entries are expired on an LRU basis.

       Many sound file formats are supported by rplayd.  These include:

           AU AIFF WAV VOC UB UL
           G.721 4-bit, G.723 3-bit, G.723 5-bit
           GSM

       Other  formats  can be played using external helper applications which convert unknown file formats to CD
       quality data which can then be played by rplayd.  See rplay.helpers(5)

       Several sounds can be played at once and sounds can  be  played  at  any  sample  rate.   rplayd  can  be
       configured to output many different formats using the various --audio options.

       On  some  systems,  namely Solaris and Linux, rplayd can read sounds directly from CDROM using CDDA.  The
       special sound name cdrom: will play the entire CDROM.  cdrom:3-5 will play tracks 3 through 5.

-ADEVICE,--audio-device=DEVICE
              Use DEVICE for the audio device (/dev/dsp).

       -BN,--audio-bits=N
              Audio device bits per sample, 8 or 16.

       --audio-channels=N
              Number of audio channels to use, 1 == mono, 2 == stereo.

       -cN,--audio-close=N
              Close /dev/dsp after N idle seconds, disabled with 0 (5).

       -FN,--audio_flush=N
              Flush /dev/dsp after N idle seconds, disabled with 0 (-1).  N = -1 : flush when spool is empty.  N
              = -2 : flush after each audio write. (not recommended) N should be <= to the audio close timeout.

       --audio-format=FORMAT
              Tell rplayd to write audio data using FORMAT, where  FORMAT  can  be  ulaw,  linear-8,  ulinear-8,
              linear-16, or ulinear-16.  (linear = signed, ulinear = unsigned)

       --audio-fragsize=N
              Audio  fragment  size  (0).   The default size is zero which lets the audio driver pick the "best"
              size.  The size specified must be a power of 2 greater than 16.  Example:  256, 1024, 4096.

       --audio-info=INFO,--info=INFO,-iINFO
              Specify complete audio device information with one option.  INFO is of  the  form:  format,sample-
              rate,bits,channels Examples: `ulaw,8000,8,1' and `linear-16,44100,16,2' Also provided are:
                  --audio-info-ulaw, --info-ulaw -> ulaw,8000,8,1

       --audio-match
              Attempt  to  match  the  sample rate of the audio device with the sample rate of the current sound
              when no other sounds are playing.  If the match fails, --audio-sample-rate is used.   This  option
              overrides --audio-bufsize.

       --audio-port=PORT[,PORT...]
              Output  audio  to  the  specified  audio  port(s).   Valid  ports  are `speaker', `headphone', and
              `lineout'.  Multiple ports can be specified using `speaker,headphone,lineout'

       -rN,--audio-rate=N
              Write the audio buffer N times per second (0).

       -RN,--audio-sample-rate=N
              Sample rate of the audio device.

       --auth Enable host access authentication.

       -DDIR,--cache-directory=DIR
              Use DIR for rplay.cache (/tmp/.rplay-cache).

       --cdrom0=DEVICE,--cdrom1=DEVICE,--cdrom2=DEVICE,--cdrom3=DEVICE
              Specify the cdrom[0-3] to DEVICE mapping.  For Solaris 2.x the default mapping  is  cdrom[0-3]  ->
              /vol/dev/aliases/cdrom[0-3].  Linux uses cdrom[0-3] -> /dev/cdrom[0-3].

       -CFILE,--conf=FILE
              Use FILE for rplay.conf (/etc/rplay/rplay.conf).

       --memory-cache-size=N
              Maximum size in bytes of the memory cache, disable caching with 0 (4194304).

       --memory-cache-sound-size=N
