PulseAudio Qt Bindings
pulseaudio-qt is a Qt-style wrapper for libpulse.
It allows querying and manipulation of various PulseAudio objects such as Sinks, Sources and Streams. It does not wrap the full feature set of libpulse. If you are missing a certain feature please file a report or send a patch using KDE's GitLab.
This is a cmake project, so you should be able to simply run
cmake (with the proper command-line flags for your system setup), then
make install if desired.
