I'm plugging the line output of my Roku XR to the Line Input of the PC.
The PC Line Out goes to a stereo amp with two 400watt Speakers.
This means I don't have to listen to audio thru the cheesy speakers
built into my RCA TV
The audio input is also switched for my HDTV converter Box.
when I'm watching over the air TV programs.
Thats just one way to do it.
