Speaker and charging not working after heatsink replacement

Hello. When I tried to reinstall the IO board, I noticed that the sounds weren’t detected. The microphone too. The connectors were installed. Then when i plug the magsafe charger, power source is power adapter, but not charging. The USB port doesn’t detect any flashdrives.

Also, the camera wasn’t working. in photo booth, the green light was blinking. the rest wasn’t detected like the speaker, mic, usb ports, but the magsafe charger when plugged, tho wasn’t charging, system says the power source is the power adapter. how come?

What may seem to be the problem and how can I fix it? Thank you. I’m on my last 80% battery life. Please help.
