You're right, these look fine.  There is one other thing.  When I open
alsamixer in capture view on my cards, there is a setting for whether
capture is line in, cd, or mic. Is your capture set to mic?

I've had to switch this in the past when I wanted to record something
from a receiver via line in or from the mic.  Record wouldn't do what I
wanted, even though it was turned on.
