Reply to S2 audio routing.

After the 2.5 update I can't figure out how to set my s2 to be the soundcard on my computer aswell, like for watching movies and such. Before the 2.5 update I was able to set it up as my soundcard, and now i can't figure out how to set it up again. I'm sure its a simple problem but if anyone could help me on how to solve it, i would appreciate it. Thanks!
