Public bug reported:

The xenial backport of the fix for 1781428 malfunctioned due to the use
of snapd-glib behaviour introduced after the version included in xenial:
namely auto-connection (and reconnection) to the snapd socket that was
introduced in snapd-glib 1.24.

With the policy module loaded, Pulse Audio will contact snapd to check
the interfaces plugged by a client in order to decide whether to provide
access to the microphone.  As the Pulse Audio daemon is long lived, it
is not uncommon for the socket connection to be disconnected (either due
to a timeout, or because snapd is upgraded while the user is logged in).
So simply adding a snapd_client_connect() call at module initialisation
time is not sufficient.

The specific snapd-glib calls that could be affected are:

 * snapd_client_list_one_async
 * snapd_client_get_interfaces_async

** Affects: snapd-glib (Ubuntu)
