Arena Specific Music, PA Sound Effects, and Crowd
"We added over 500 new arena-specific sounds and music clips to enhance the realism of the uniqueness of each NBA arena in 2K12. You’ll hear the fire-truck siren after a big dunk by Josh Smith, or the screech of a hawk after a clutch basket in Atlanta. While many new sounds were added for the superstars of the NBA, this year we made a big effort in expanding coverage to a lot more players. When Jonas Jerebko drops in a bucket, you’ll hear his customary horn sound effect, and custom-style situational PA calls were added for dozens of players including the likes of Ty Lawson and Tayshaun Prince:"
I never encountered this in my game. I've tried to set sound effects and PA vol to 100 but still don't hear any arena music..
