--- Comment #12 from Philippe Normand <pnormand at igalia.com> ---
OK I've rebased to F34. Can reproduce the issue now:

So we call setMuted(true) and get a GObject notification from playbin but the value is false instead of true, and a while later another notification which is correct this time...
