Description:
Musescore cannot play audio with pulseaudio. This is the log output:

$ LANG=en_US.UTF-8 mscore
using qt5ct plugin
initScoreFonts 0x3294230
pa_stream_new failed: Invalid argument
init PulseAudio failed
no audio driver found
init Help from: </usr/share/mscore-2.0/manual/doc_en.qhc>
cannot setup data for help engine: Cannot open collection file: /usr/share/mscore-2.0/manual/doc_en.qhc
Cannot start I/O
sequencer init failed
QNetworkReplyImplPrivate::error: Internal problem, this method must only be called once.

Mscore also displays a small window in the background with the title "Loading..." and an empty loading bar inside.

Jack playback works fine as a workaround.

Steps to reproduce:
* open Musescore
* the playback buttons will be greyed out
This task depends upon

PulseAudio works fine here, did the last release fix this or does it still happen? Did you try reverting your PulseAudio configuration to the default?
