sound not working after reassembling

Hi, I recently purchased some tools from you to replace my macs dc connector. Everything went ok, but I have lost the audio. Can you tell me which connector to check to make sure I plugged it in good? Thanks

I would attempt to reset the PRAM (hold command + option + P + R while powering on until you've heard it chime twice).

If that didn't work I would reset the SMC

Make sure your Mac is connected to power and turned off
Press and hold the left Shift + Control + Option buttons while pressing the power button for 5 seconds
Let go of all the keys & button
Attempt to power on after waiting 2-3 seconds

If it still had no sound then I would check the subwoofer cable and the left speaker cable

Hopefully one of those steps fixes it for you!
