Hello,I just got a Neo geo mvs arcade everthing works fine exept the sound,If anybody can help me out how to fix this problem,Thank you!!!!!!!!!!!!!!!!
 
1. Adjust volume control, flip DIP switch 1, power it up, and see if you get sound on the hardware tests. (Player 1 start to choose test, joystick and player 1 button 1 to select options on the screen.)

If you have sound proceed to step 2. If you have no sound and you are sure the wiring/speaker is good in the cab then install an audio cap kit.

2. Reset the backup memory. It's in the hardware tests. When done, flip the dip switch back and test a cart.

If you have sound, enjoy! (And let it run for 24hrs to charge the battery on the board)... If no sound here but you DO have sound on the hardware tests then clean the slots and the cartridge edge connectors.

http://www.hardmvs.com has instructions on cleaning the carts/slots.
 
I just installed a Universe 4.0 bios and no sound. The slider works in that I can hear the white noise from the speakers get louder when I turn the volume up.

This is a MVS 4 and I think I am using the right bios version. The Jukebox player errors when I try and run it too.
