What steps will reproduce the problem?
(0) Sign in 
(1) Plug USB headphone 
(2) Play any youtube music 
(3) Plug hdmi cable 
(4) Unplug USB cable 
(5) Unplug hdmi cable 
(6) Plug USB headphone 
(7) Plug hdmi cable ( audio can be heard via hdmi)  
(8) Repeat step 4, 5 
(9) Close youtube page 
(10) Plug USB headphone 

What is the expected output?
-USB headphone should be auto-selected as audio Output under ubertray 
-Audio should be heard via USB headphone  

What do you see instead?
-USB headphone is not auto selected as audio Output under ubertray 
- Audio heard via speaker 

Always, tried several devices new or old  
if plugging 3.5 mm headphone at step 10, it's auto-selected 

P2 as it's involving long steps

So by the repro steps, on the third plug of USB headphones (having HDMI always following USB), the USB audio node does not show.

Is step (9) mandatory i.e. closing the source of audio. Can you reproduce with other audio source, or even without playing audio?

In step 8: Active node is HDMI and Inactive node is USB 
Now if we unplug USB head phone first ( repeat step 4) then this node will be in Inactive state. 

In Step 10: we are plugging USB headset which is in Inactive state.

@Helen can you please confirm the USB Headset state(Active/Inactive) while Unplugging in step 8.

Yes, step 9 : close youtube is optional. USB headphone is listed under Ubertray, however it's not auto switched/selected as output. 
Audio Input under Ubertray is switched/selected as USB microphone.

sontis@ is right - at 4) hdmi becomes active output, resp. in 7) it becomes active too, and b/c in 8) we unplug USB headphones while not being the active output node(but active input node), then it is remembered as such, and plugging it back later in 10) does not enable it as active output, but just active input.

This is WAI. Interesting user case though.
