Chromium does not pick default pulseaudio sink

Bug #1793334 reported by Raul Dias on 2018-09-19

Bug Description

When changing the default sink (builtin audio) to USB audio (PCM2902) headphone, all desktop uses the new default sink.
All but Chromium (and Chrome).
For both Chromium (and Chrome), I have to change the output device in the application tab (PA). As soon as the audio pauses in Chrome/Chromium, it will resume in the builtin output audio device sink. This happens on a per tab basis (probably different process).
