Public bug reported:

Sometimes when i start up firefox in the morning i can't hear any audio.
Or sometimes a page that wants to play audio will freeze, waiting.  When
these happen i'll launch pavucontrol next and it'll say "Establishing
connection to PulseAudio. Please wait..." and just keep waiting.  i look
for the pulseaudio process, it's there as usual.  Even so i just launch
an additional pulseaudio process, and then pavucontrol is immediately
all happy.  Firefox might also immediately become all happy, or less
often i'll also need to restart firefox before i can play audio.

i usually shut off my computer at night.  Starting it up each morning,
manifestations as described above might be separated by a couple weeks,
or might happen a couple times within a week.
