I had my friend pop in to make sure the audio was set up correctly and it seems to have been okay. But I noticed some mic feedback after I stopped streaming so there might have been a delayed mic echo but noone complained I guess.

Of course, that may be because noone was watching. :P
But it's not like I had any expectations of getting followers immediately, so it's no problem.
