Ah ... mine have more.  <F4> in alsamixer brings up all these Capture devices:

Front Mic  67<>67
Mic        67<>67
Capture    80<>80
Capture    80<>80
Digital    61<>61
Digital    33<>33
Input So   Digital Mic  (other options are: Front Mic, Mic)
Input So   Digital Mic  (other options are: Front Mic, Mic)

There's a microphone on the top of the screen and a jack on the front left of
