OK, Line is set as the capture source. I tried this, as a diagnostic test:
,--
| eben@pc:~$ arecord -t wav -c 2 -r 44100 -d 10 -f S16_LE > test.wav
| Recording WAVE 'stdin' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo
| eben@pc:~$ aplay test.wav
| Playing WAVE 'test.wav' : Unsigned 8 bit, Rate 44100 Hz, Stereo
| eben@pc:~$
'--
and nothing got recorded. In fact the file looked like this:
,--
| eben@pc:~$ od -t x1z test.wav

I heard the Line In (live) through my speakers, since I've got it unmuted.
Are there any other sliders or switches I need to twiddle?
