Exactly, this is about the most common problem encounter in getting
started. Usually it's just a matter of using alsamixer to set your
"Line" as "CAPTUR" and to turn up the volume on the slider with the
sub-caption "Capture".

To be expected but at least that confirms that the analog signal
is reaching the sound card. Now you just need to digitize it with
the DSP.
