I have an mk2 start up bong is good and loud.
Then no sound in games, in test no sound except the single tone in the sound board test that indicates hardware is good!

Everyone is having mk2 sound problems at same time!
haha

I appreciate any and all help!
Thanks@!

the bong signifies that your cabling is correct. so I'm going to say it's probably the same problem I had with my MK2, and the UJ12/UG12 roms have corrosion on the chip legs OR they're not seated into the sockets all the way.

you ever get any random UE13 Custom Chip Bad errors ever? game resets itself over and over?

I wouldn't be suprised if the chips just do need reseated. I have never used this pcb, and I do know it spent some time in less savory storage. I just tried the game with no sound/no cable a week ago for first time and had grafix glitches, reseated some chips on main pcb and it was fine then.
I haven't hardly had the board running for more then 1 minute, so I'm not sure about errors and resetting, but ido think when it first boots it says something about some error wioth bios and just using factory defaults? Ididnt completely catch it. Does that make me any sense?
