Summary	07552: wwfmania, wwfmaniab, wwfmaniac, wwfmaniap: Sound stops working during attract mode
Description	After attract mode displays the first wrester profile (it always seems to be Razor Ramon), the game's audio goes silent.
Steps To Reproduce	1. Run attract mode until you reach the Razor Ramon profile screen (approximately 2m40s in) 2. Let attract mode advance to the next screen ("Intercontinental Champs" leaderboard), then insert a coin. The game won't have any audio unless you enter service mode or reset the system.
Additional Information	-Before testing, increase the game's volume via the service menu -To reproduce the error more quickly, hit buttons (punch, kick, etc.) to skip screens during attract mode
