Windows 7 audio playback

Hi, I’m new to this system/forum.
I cannot seem to hear the record player through my laptop, I’ve tried adding an external speaker system to no avail, if I pull the codec? Cord, my laptop goes back to normal. I’m trying to hear what’s recording, while recording, and playbacks. Any tips? Thanks mike

I don’t understand what you mean.
What is the “cord” and what are you doing with it to make the laptop go back to normal?
