S6000 - ProSound 2 Dragon Wheel no sound during bonus

[Nurbo]

Hello,


I have a Bally S6000 Dragon Wheel. It is equipped with a ProSound 2 - AS-03356-0512 rev D.

When there is a normal gain I have music as an Alpha S9000.

When I trigger a bonus, there is a voice that says I have to turn the wheel, BUT, when the arrow turns, there is no sound.

Here is a video of my machine:

In this video found on YouTube, there are many sound when the arrow turns:

This is the ProSound board in my machine.



The socket circled in blue is empty. The one circled in yellow seems to have a chip inside.

Do I have to find a special chip for this game ?

Thank You !
