|Tester||Endaar||View Status||Public||Platform||MAME (Official Binary)|
|Version||0.128u6||Fixed in Version||Build||Normal|
|Summary||02778: suzuka8h, suzuk8h2, finallap, finalap2, finalap3, fourtrax + clones: Music Playback becomes buzz/humming|
|Description||Shortly after starting the game - basically, as you get on the motorcycle - the music stops playing and turns into a loud hum. Sound effects continue to work normally and the game is playable.|
|Steps To Reproduce||Insert coin, start game.|
I tried a number of other games with the same driver. This issue appears to exist in Final Lap and Four Trax, although in both it is less noticeable. Four Trax's music actually worked briefly after the race started but then turned into a hum as well.
I did not try every single game sharing the driver, but a number of others work normally.

the buzzing is the engine sound... probably wrong tho, definitely sounds strange.
the ym2151 is silent at this point, so if it's meant to be playing some music, that is also a bug.

|I just uploaded a quick audio clip of what happens for me. This is right as the game itself starts and the rider is on track ready to run to the bike. There appears to be music which then turns into the hum. Maybe what I'm thinking is music though is just a sound effect. Anyway, hope it helps.|

According to Guru, testing on his real Final Lap 3 PCB:
"on real hardware if the voice2 ROM is removed there's still in-game sound whereas in MAME there are no in-game sounds and if both voice ROMs are removed from the PCB the in-game sound is almost exactly like in MAME, which suggests the voice ROMs are incorrectly mapped or a mirror mapping is missing."
I guess it could also be different c140 banking. Currently the device has 3 different banking types but maybe there's at least a fourth one?
