No sound output device on Xubuntu 18.04.4

[krasoffski]

It is not possible to configure sound output after installation from ppa.

Launching from shell shows following:

Warning: Audio format is not supported by device ""
using null output device, none available
Warning: Audio format is not supported by device ""

Some QT5 libs missing?

There is an issue with the dependencies of the DEB packages. It should depend on libqt5multimedia-plugins (see issue #14). Please install libqt5multimedia5-plugins manually, eg. using

  $ sudo apt-get install libqt5multimedia5-plugins

on the command line. I'll fix that for the next release.
