I've found that if I try to record stuff off the air using mencoder, I 
have to explicitly switch the mixer to record from "line" to get audio 
recorded. Mencoder is supposed to do this internally via "adevice", but 
that option seems unsupported on FreeBSD.

Try running "mixer =rec line rec 100" just before you start nuvrec.
