Bug#973851: musescore3: "PulseAudio Context Connect Failed with Error: Connection denied."

[rv]

Package: musescore3
Version: 3.2.3+dfsg1-7
Severity: important
X-Debbugs-Cc: riveravaldezm...@gmail.com

Dear Maintainer,

   * What led up to the situation?

AFAICT last upgrade.

There's no playback audio in notes input.

Launching musescore3 produces this output:

$ musescore3 
PulseAudio Context Connect Failed with Error: Connection denied
init PulseAudio failed
no audio driver found
Cannot start I/O
sequencer init failed

But PA seems to be running fine and audio works (for instance, with mplayer and 
audacious).

Let me know if I can add any useful information.

Thanks a lot, best regards!
