I too encountered this problem: Bluetooth audio stopped working after I
upgraded to 16.04.
Running pulseaudio -v, I saw my headphones connect, then the
TryAcquire() error message from the subject line of this bug:

/org/bluez/hci0/dev_00_18_09_24_DD_95/fd3 (Operation Not Authorized)
Digging into the source, it looks like TryAcquire() simply tries to send
a message over the DBus. A little digging led me to
/etc/dbus-1/system.d/bluetooth.conf, which contains the following:
<!-- allow users of bluetooth group to communicate -->
<policy group="bluetooth">
<allow send_destination="org.bluez"/>
</policy>
<policy at_console="true">
<allow send_destination="org.bluez"/>
</policy>
I tried adding myself to the bluetooth group, restarted, and boom! now I
have audio.
So it appears something changed between 15.10 and 16.04 w.r.t. the DBus
permissions - the behavior of at_console perhaps? The bluez package
owns the above config file, so I added it to this bug.
