My current use for this, is for my friend's system that I'm helping him with. One of his wishlist items is to be able to do something like this:
Play a sports event on the TV in his living room, with the audio playing through his main 5.1 system. Then, route that same audio to other zones in the house, outside, etc. Since most sports are going to come in via external tuners (OTA, Cable, etc), I was thinking Line In was the only real solution.
Can line in work from a separate sound card? Like a built in RealTek card? (yeah, I know they are not respected at all, but there's one onboard, so I'm asking). Otherwise, I'm guessing that something like the Asus U7 won't work for both input and output at the same time, right? The MOTU stuff looks nice, but I think it's out of the budget range unfortunately.
Thanks for the response!
Brian.
