Dodgy sound when i installed a infinity chip

[seaneyb2003]

Well... another ps2 installs gone wrong. I installed a matrix infinity in my v7 console. I turned it on and the ps2 loads properly displays fine but the ps2's music is all wierd and kinda spooky sounding its like distorted. I goes to play the games like normal it goes to load and it goes to a blank screen and goes back to the menu and shows i have a ps2 game in the drive. Im not sure what it could be Heres a pic below but im unsure of what it could be. Ive rechecked over the bios area. Is it the 3.3v power wire? im not sure can someone help
