[pulseaudio-discuss] Inserting headphone "locks" audio

[John Oliver]

I have two drop-downs, both titled "Built-in Audio"  The top is "Digital
Stereo (HDMI) Output" and the other is "Analog Stereo Duplex"

I'm not clear on what I would change.  The top one has a bunch of other
options, all of which are unplugged and unavailable.  The other has three
more options... "Analog Stereo Input", "Analog Stereo Output", and "Off"
