Binary package “libpulsedsp” in ubuntu bionic

PulseAudio OSS pre-load library

 PulseAudio, previously known as Polypaudio, is a sound server for POSIX and
 WIN32 systems. It is a drop in replacement for the ESD sound server with
 much better latency, mixing/re-sampling quality and overall architecture.
 This package provides the pre-load library used to redirect applications
 using OSS through pulseaudio.
