Wtf is with all the livestreams all of a sudden? Not saying yours sucks but COME ON O.o
Huh?
Not sure.
I just set mine up because I'm terribly bored, and trying to find things to do.
Set the audio input to "Speakers' Audio".
I tried that, too. It still didn't make any sort of sound. I'm not playing any sound at the moment, though, so hard to tell.
If it helps, I have an IDT HD Audio chip (Dolby Home Theater)
