Internal Audio/Headphones not working after SuperDrive Removal

I removed my superdrive in preparation of getting an OptiBay for an SSD I have. Minus the struggle of sausage fingers and tiny screws, it went off without a hitch, threw the computer back together, and everything went along as I expected until I tried to play some music. There was no audio. I plugged in a set of headphones with no luck, although I did hear the distinctive "pop" in the headphone when plugging it in.

Bluetooth audio, as expected, works fine. I took an abundance of pictures hoping someone will say "oh, dummy, you probably used the wrong screw in this hole", as I will admit that I did not keep my screws as organized as I should have. Pictures are here: http://imgur.com/a/yGW3u#0

I also included snapshots of my System Information and Audio pref pane. Any help/suggestions would be greatly appreciated.
