Summary	08421: stakwin: Sound stuck in infinite loop bug
Description	After finishing the first race, the music will get stuck in an infinite loop. The music should stop after each race, but it just continues over and over in an infinite loop for the rest of the game.
Steps To Reproduce	1. Start playing the game as normal. 2. Finish the first race (the bug is most likely to happen if you finish in the top 3 and qualify for the next race). 3. At the end of the race, the music will get stuck in an infinite loop for the rest of the game.

The next time of running the game, it seemed to be ok. The error log shows missed reads of the soundlatches. [soundlatch2] is always missed, but [soundlatch] is only missed on the first run - this is where the problem comes from.
