[Bug 1378969] Re: pulseaudio doesn't enforce remembered volume when changing to HDMI output

hurray for one-file-at-a-time

** Attachment added: "hdmi-before"
   https://bugs.launchpad.net/ubuntu/+source/pulseaudio/+bug/1378969/+attachment/4228770/+files/hdmi-before

** Description changed:

  When I change my sound output to use a HDMI output, even though `pactl
  list` reports the correct volume level, the output volume is in fact
  100%. Executing the following command afterwards solves the problem.
  
  $ pactl set-sink-volume <SINK-NUM> +0
  
  Attached is three outputs of `pactl list`:
  1) "hdmi-before" : taken when HDMI output is working as it should
  2) "hdmi-after" : this is taken after changing away from the HDMI output (to laptop speaker), and back to HDMI again -- reported volume level is 50%, but real output level is 100%.
- 3) "hdmi-after-adjust" : taken after executing the command listed above (which sets real out level to 50%)
+ 3) "hdmi-after-adjust" : taken after executing the command listed above (which sets real output level to 50%)
  
  If it has any interest, I used the built in system settings to change
  sound output (even though the same problem occurs when doing so from the
  command line).
