Bug#768918: pulseaudio: Streams do not switch to correct sink when USB speakers are removed

Package: pulseaudio
Version: 5.0-13
Severity: normal
I have added these lines to my /etc/pulse/default.pa:
# fc-added
set-default-sink alsa_output.pci-0000_00_1b.0.analog-stereo
set-default-source alsa_input.pci-0000_00_1b.0.analog-stereo
load-module module-switch-on-connect
These define a default sink (and source), and loads module-switch-on-connect,
which correctly causes pulseaudio to switch any playing streams to my external
USB speakers when I plug them in. I expect that when i unplug the USB speakers,
playing streams will return to the default sink which I have defined in my
config. This does not happen. What happens is that pulseaudio switches the
stream to its sink #0, which is an HDMI audio device that is not connected to
any output.
When I check the default sink again after having unplugged the USB device by
checking the output of "pacmd list-sinks" and looking for the asterisk, it is
correctly set back to the default I've defined in my config.
My suspicion is that the module module-rescue-streams, which is responsible for
switching streams once a sink becomes unavailable, is being called _before_ the
default sink is set back from the USB device to the config-defined default
device, and it is choosing the first available sink it finds, which is #0. (The
function find_evacuation_source in module-rescue-streams.c looks like it would
do that, although I haven't been able run it in the debugger and set a
breakpoint to check.)
