[Cialug] Firefox >60 audio

[L. V. Lammert]

Happened to try and watch a Youtube video last week on my laptop, and
could not get audio working; found notes about a serious issue with newer
FF versions on Linux playing Youtube audio.

In this case (my laptop):

 * VLC works fine (been using it for at least a year) w/HDMI
 * Audio works fine on a desktop (SueSE 15), but NOT on my laptop

Found notes on three possibe issues:

 * pulseaudio: enabled and running
 * DRM:  enabled
 * Media setting in about:config: True

Anyone else encountered this yet? As VLC uses HDMI audio, it may be
something with switching sources? IOW, with VLC both HDMI & internal are
available, .. but with Youtube last week HDMI was not available.
