It starts with two sections labeled Built-in Audio. One of them says 
Profile: Off, and the other says Profile: Analog Stereo Duplex.
When I connect the turntable a third section appears labeled PCM2900. It 
says Profile: Analog Stereo Duplex.

Clicking on the down-arrow provides a list of options, some input and 
some output. If I select Off, the sound returns to the speakers. Sound 
remains playing through the speakers when I select Analog Stereo Input, 
or Digital Stereo (IEC958) Input. I assume, coming through USB, the 
latter is the one I'll want for recording an LP.

This may solve the problem. Just to see, I left the USB cable plugged in 
and restarted the machine. When it came up, PCM Audio Codec still had a 
profile Digital Stereo (IEC958) Input.

So maybe it just needed to be told what I want it to be and will keep 
that going forward? Hope, hope.
