The set suggestion sounds good excepting the rigorous definition of a set which is an unsorted collection of objects.
It sounds like what you want to do is some kind of set difference or intersection type ops on an array and use NULL as an empty marker. is this correct?

RPLAY(1) General Commands Manual RPLAY(1)
NAME
rplay - play, pause, continue, and stop sounds
SYNOPSIS
rplay [options] [sound ...]
DESCRIPTION
rplay is client that communicates with rplayd to play, pause, continue, and stop sounds using both the RPLAY and RPTP protocols. Sound
files can be played by rplayd directly if available on the local system or sounds can be sent over the network using UDP or TCP/IP. rplay
will attempt to determine whether or not the server has the sound before using the network.
OPTIONS
-b BYTES, --buffer-size=BYTES
Use of a buffer size of BYTES when playing sounds using RPTP flows. The default is 8K.
-c, --continue
Continue sounds.
-n N, --count=N
Number of times to play the sound, default = 1.
-N N, --list-count=N
Number of times to play all the sounds, default = 1.
--list-name=NAME
Name this list NAME. rplayd appends sounds with the same NAME into the same sound list -- it plays them sequentially.
--help Display helpful information.
-h HOST, --host=HOST, --hosts=HOST
Specify the rplay host, default = localhost.
-i INFO, --info=INFO
Audio information for a sound file. This option is intended to be used when sounds are read from standard input. INFO must be of
the form:
`format,sample-rate,bits,channels,byte-order,offset' Examples: ulaw,8000,8,1,big-endian,0
gsm,8000 Shorthand info is provided for Sun's audio devices using the following options: --info-amd, --info-dbri,
--info-cs4231. There's also: --info-ulaw and --info-gsm.
-p, --pause
Pause sounds.
--port=PORT
Use PORT instead of the default RPLAY/UDP or RPTP/TCP port.
-P N, --priority=N
Play sounds at priority N (0 <= N <= 255), default = 0.
-r, --random
Randomly choose one of the given sounds.
--reset
Tell the server to reset itself.
--rplay, --RPLAY
Force the use of the RPLAY protocol. The default protocol to be used is determined by checking whether or not the server has local
access to the specified sounds. RPLAY is used when sounds are accessible, otherwise RPTP and possibly flows are used. RPLAY will
also be used when sound accessibility cannot be determined.
--rptp, --RPTP
Force the use of the RPTP protocol. See `--rplay' for more information about protocols.
-R N, --sample-rate=N
Play sounds at sample rate N, default = 0.
-s, --stop
Stop sounds.
--version
Print the rplay version and exit.
-v N, --volume=N
Play sounds at volume N (0 <= N <= 255), default = 127.
