Excellent, thanks so much! I had been under the impression that you had to pay to get the radio broadcast directly from LSU (Geaux Zone, I believe?).
I saw "northernva" and assumed you might be using that service or one CBS used to provide—both pay per listen. A simple google search with keywords sync, radio, internet, and live tv should give you dozens of options to choose from to sync the two.

wwl radio 870. On a clear night, you can hear them all over the country. wwl.com They have been THE radio station for out of towners to catch the game for all of my 52 years. They are out of New Orleans.
