I am having sound issues with the board. On boot-up there's no Gong sound. But after a while you hear 2 gong sounds. So i am wondering if the U2 chip is done. Or something else is causing the issue. Graphics and game itself plays perfectly. No audio even after the Test mode to adjust it. If someone can help me here to pin point it. That be greatly appericated.
 
Have you tried unplugging the audio board cable. Maybe check your voltages coming out of the power supply. Sometimes the MK boards get funky when the voltage is off.

Definitely. Ive had this exact problem due to a lack of power.

My Vegas 777 boards will always reboot or do funky stuff it they don't get enough voltage. If I remember correctly, so did my Crusin Exotica.
