If your speakers are connected via the line out on the soundcard, then 
the audio must be being captured from line in unless you have 
hardware monitoring features (often called 'zero latency 
monitoring').

If that's not the case (ie you are not routing the speakers through 
the soundcard) and assuming your soundcard is fully supported by the 
installed driver and is set up correctly, it sounds to me like you 
haven't got your mixer set to the right channel for recording from 
line in.

If you have ALSA drivers installed, try running alsamixer and see 
which channel is set for 'capture'. If you have OSS drivers, try 
aumix or kmix.

If that fails then I would go back and check that your soundcard is 
fully supported by the driver, then try some setup tests.
 
Cheers
