Front Panel and Back audio does not work

[Painless32]

I got a new power supply (same as old one). I unplugged everything and plugged my new PSU in. So far I see no problems but even performance boosts such as Faster boot and system running cooler. When I boot into windows I notice a muted sound Icon on the notifications. I click it and It starts searching for solution. I may have incorrectly plugged the yellow audio cord to the pins or something but I double checked it. I check device manager and search for hardware changes, doesn't even find my Realtek HD audio. after this i tried plugging in the Green and Pink cords to the back of the computer, still doesn't find it! Please help

Nevermind guys I figured it out in the bios there was a setting
"Onboard Audio" it was set to Auto. I set it to Enabled everything works now.
