New Pulsar Pachislo - no sound

[Kaasie]

Hi Guys, I have a good new Pulsar pachislo like this one:

It's fully working but Im not getting sound. Can you control this on the power supply? It has the sound card in it but can you control sound via the buttons and if you, how?

Thanks for helping me out if possible
