I'm working on the sound on my system running 8.2-RELEASE.  Currently I 
have sound input and output working using snd_hda (i.e. I can record on 
line in, and play it back on line out).

What I would like to do is take the audio coming in on line-in and send it 
back out the line-out "live" without recording it.

Is this easy to do?  I'd appreciate any hints.

Thanks,
Brandon
