Audio problem: As Eddie walks into the bar with Roger stuffed into his coat, you can hear somebody shooting pool. But only two seconds later Eddie walks past the pool table and, here, we can see one of the patrons actually passed out and laying down on top of it. It would be impossible to shoot pool under those circumstances, which means the pool ball noises were dubbed over.
Audio problem: The first thing we can hear as Eddie walks upstairs into the bar is a rack of pool balls being broken. But two seconds later he greets his buddy Harry, and at this point we can see how all of the balls have settled and a player is lined up and prepared to take his shot at the corner pocket. It takes more than two seconds for a rack of pool balls to settle.
