Jack de Sena, aka Sokka is in some kinda web tv show called 'Dorm Life'
He stars as a party boy name Shane Reilly

I've been watching the series, its amusing especially to hear Sokka scream out 'BOOBIES!'
He doesn't appear to really change his voice much from how he sounded as Sokka anyways. haha.

Here is Episode 1 for your viewing pleasure:
