No. If you have a cable inside your box that goes from tv card audio outlet -> 
audio card line inlet it'll be line1, not line. So you can still use the line 
channel for extarnal audio that you want to get into your soundcard as the 
line-in. But not all tv cards have this.

No. There are (many) cards with a sound processor of their own, but as far as 
I know on FreeBSD they don't get their own mixer (as on Linux) but rather 
become the video mixer channel (or something).
