rplay-client 3.3.2-17build1 (riscv64 binary) in ubuntu focal

 This package contains the basic rplay clients (rplay, rptp). The clients
 are used to play sounds on the local host or remote systems.
 .
 RPlay allows sounds to be played to and from local and remote Unix
 systems. Sounds can be played with or without sending audio data over
 the network using either UDP or TCP/IP. RPlay audio servers can be
 configured to share sound files with each other.
 .
 Support for RPlay is included in several applications. These include
 xpilot, xlockmore, xboing, fvwm, and ctwm.
