It appears I wasn't the only one with this experience, as I received an e-mail that says:

Dear V-Pass Customer,
We apologize the live online audio broadcast of Georgia Tech at Virginia football game on Saturday, Sept. 22 dropped silent near the end of the game. We have resolved the technical issue that caused this to happen and we are confident a similar occurrence will not happen again.
Pay $40, and it conks out right at the end of the game.
