I had profile "Output Analog Surround 5.1 + Input Analog Stereo".  I 
also tried "5.0".  This is pulseaudio-0.9.15.  Perhaps this is a known 
issue addressed since then?
I just tried switching to "Digital stereo output" and the hardware 
device disappeared!  And now there is no way to switch back...
