I do a *lot* of recording with my SBLive! card and FreeBSD. It's all 
guitar and drum machine through a 4-track, plugged into my sound card. The 
trick with the line-in (at least on my rig) was that the input volume on 
that channel was zero by default. I use the 4-track to do a little pre-mix 
before recording.

I found that if I pull up an audio mixer (kmix, since I use KDE) I can 
bring the level up on line-in just fine. However, I have found that for 
certain tracks the mic input is better, although I have to bring the input 
gain down with kmix. Also, if you need to 'clean up' your recordings to 
get the 'eggs-frying' noise out of the mix (all my vinyl has it :), 
Audacity has great noise filters and it's in the ports collection.


PS: If you want to carry on this discussion and feel it too off-topic,
