but for some reason they didn't go with that audio-stream

Wait, what? I really looked forward to this one since I read the slides when they appeared. Then i watched a portion of the talk and skipped to your exciting demos, because I couldn't understand anything you said.

Is there any possibility to get a new video with the other stream?

I listened to this right through over laptop speakers and heard every word without problems. Perhaps you're just not used to Sam's English accent?

Yes, that's a problem too.
