Using $alsamixer, then F6, then select "0  HDA Intel" and un-muting S/PDIF
gets HDMI audio going, but you can not control the volume. Further more the
changes are lost after a reboot.

If you install pavucontrol and configure it to use HDMI, the changes are
saved, but the keyboard multi-media controls have no effect on pulseaudio

Please note pavucontrol worked fine in Wheezy. Both Jessie and Wheezy use
the Xfce desktop.
