Public bug reported:
pavucontrol shows Display Port/HDMI output as "(unplugged)" and cannot
be chosen as a sink. This is only a problem with the dock; audio works
when plugging HDMI through the laptop's DP input.
The audio did work with the dock in Ubuntu 14.04. Did something in jack
detection change? Anyway, my work around is to plug a 3.4mm audio cable
into the dock and power the speakers that way, but it would be nice to
use the HDMI audio again.
I would love to have a work around. I've attached the output from alsa-
info.sh, just in case this is useful.
