Hmmm, OK. Is that all one line in the alsa file? Not sure I understand
that. lsusb -v shows me this for my one USB audio device:

idVendor 0x041e Creative Technology, Ltd
idProduct 0x3f07

That's pretty clear about what's what. I gather I need a line like this
in the alsa file (index=2 to make it the second sound device, yes?):

options snd-usb-audio index=2 vid=0x041e pid=0x3f07

On the other hand, lspci -vn shows me this for the onboard audio controller:

00:1f.5 0401: 8086:24c5 (rev 03)
         Subsystem: 1179:ff01
         Flags: medium devsel, IRQ 11
         I/O ports at 1c00 [size=256]
         I/O ports at 18c0 [size=64]
         Memory at e0100c00 (32-bit, non-prefetchable) [size=512]
         Memory at e0100800 (32-bit, non-prefetchable) [size=256]
         Capabilities: [50] Power Management version 2

I guess the "8086:24c5" is the two numbers I need, minus the prefatory "0x"?
