Incredible Hulk sound update.

Maybe this might help a newb like me. Lol. I had no game play sound on my System1. The taunt sound came on so I knew it wasn't a speaker/soundboard issue. Changed all pins leaving the power supply and still nothing. I finally tried something new (after 2 weeks of troubleshooting ) lol. I held the reset button on the mpu for 12 seconds, restarted the game and it's working. Lol. Might be obvious to some but it wasn't to me. Tks y'all.
