Never had an arcade board before. After swapping in darksoft's cps2 board theres no sound.
Set up...
HAS Supergun
MVC rev 7 pal g used for multi
Mwp 606 psu
I've checked each pin and things seem fine. Tried reconnecting everything multiple times.
And yes I've tried holding down each button on the A board as it boots to try to reset the audio.
I have a naomi 2 that has sound working through this supergun with the same set up, so I'm sure its an issue somewhere in the c0s2 boards but I honestly don't know where to begin.
Should I try replacing the super cap on the a board?
Thanks for your help

Old romset by the way. Maybe its the roms??

Updating original post to keep track of what issues I'm seeing and what I've tried.
Issues...
No sound
Test suite reports sound init was bad.
Test suite shows correct System Speed but then shows it's value gradually decreasing over time. Voltage remains steady at 5V on Jamma edge though
Green screen on booting an encrypted game.
Tried...
I've tried cleaning everything with 99% IPA.
Probing 5V and Ground on the Jamma edge correctly reports 5V
Removing and reconnecting A/B/Multi boards repeatedly.
Checked for bent pins, none appear bent. One set of 2 were bent slightly and I straightened them.
Tried different rom sets. Decrypted "work" but then slow to a crawl.
Connected Naomi to HAS supergun, confirmed sound works.
Double checking solder connections from QSB to key writing pads. Seems good.
Tool to check flash writing reports fine for both tests.
