The only settings on an Sigma150b are the volume settings for the game Volume, and door alarm.
So something is wrong beginning where the sound ROM chips are on the MPU board.
I photo a couple of pictures I hope will help but I'd like you to remove
the two sound ROMs to check for a folded-under eprom leg.
While you are able to perform the sound tests, for some reason it's not outputting the sounds during game mode.

For each sound that is generated, it needs an input from the microprocessor to command a read sound byte from the two ROMs to produce sound for an event.
If one of the eprom legs on that line are folded underneath the chip body, then it's being allowed to complete the command for the sound event.

Be very, very careful when re-inserting the eproms so you don't fold a leg underneath.
Use a magnifying glass if possible to make sure you see that each leg in firmly inserted into the chip sockets.

Here's some pictures you can look at and they can be opened in another webpage to be enlarge if needed...>>>

Are you sure it is a 150b and not a 150plus?...Post photo's of your MPU board if not sure...
