I've chatted with the manager and he tries to never start audio for something he can't keep on the whole time, and trivia wins out over sports on trivia nights. so even if the game started at 8:00, he'd avoid putting the audio on if he knew it was going to have to be shut off for 9:00. Stinks, but I can understand.
But yeah audio levels for trivia can be atrocious.
But, 'Merica !
