Thought it was "Hey, you okay?" but I'm not good at reading lips, so you might be right. ;) It's from the Spartak UMMC game in the 2008-09 Euroleague. Spartak and UMMC met in the semifinals, Spartak won and went on to threepeat the Euroleague championship over Halcon Avenida.
Don't know what's going on exactly. You can't hear anything from the original video either. Best guess is someone off screen was saying something or otherwise being disruptive during a timeout while they were trying to listen to the coach.
