I did some poking around in the code and it looks like it sets the
volume for the device based on the value from the recording

Perhaps if you make up some new recording profiles with different
volume settings and assign them to the different inputs. It's been a
while since I poked around the backend setup screens, so I don't know
how easy that is, or if it's possible to use different recoding
profiles on the tuner and composite inputs of the same card.

I might try it this weekend, since I have the same issue.
