Summary 06445: mk: [possible] In attract mode at the certain point, music and fx are off
Description Launch mk and watch the attract mode, that is a loop of the following sequences:
Mortal kombat title, score screen, character bio, some demo fights

After the 4º loop with the scorpion's bio, the sound and fx are off. I would like if someone can check it with an original pcb.

If you insert a credit, the fx works and the music plays in the character selection screen,
Steps To Reproduce Wait until the subzero bio is displayed in attract mode (5ºloop).

Demonstration sound for many games isn't on 100% of the time. Some alternate between demonstration sounds, demonstration silence. Atari games were known to only play demonstration sounds once every 4 or 5 loops (Indiana Jones: Temple of Doom [indytemp], for example). Mortal Kombat 2 [mk2] does a similar thing.. muting sound after a few cycles of the title screen and it has completely different sound hardware.

I honestly don't believe that something like this is even worth investigating.

After what you said and some time investigating, I think you're right, is the normal behaviour of the game. You can close the report unless someone would like to compare it with a real pcb...

I remember perfectly about it.
After a time attract sound is disabled and will be enabled after some cycles.
Tafoid is correct. Several arcades work of same mode.
Emulation is correct too ;-)
