[Impact]

A HDMI audio device usually has several output ports, each port
represents a profile in pulseaudio, without this patch, the puseaudio
always choose the first profile no matter it is active or not.

[Test Case]

connect each port of HDMI device, and check if the profile of that port
is active or not.

[Regression Potential]

no regression possibility, since this commit is already in artful and
bionic.
