Desktop not recognizing speakers.

[xeloth12]

So, not sure if this is the right place to post this, but I was cleaning my desktop for the first time with an air duster. After I had finished cleaning it out I plugged everything back in, and everything worked fine except the sound. It says I have Realtek Digital Output and Realtek HD Audio Output 2, yet it won't recognize the speakers or headphone in either the front or back jacks. If it helps I'm using an ASrock FM2A75M Pro 4+ motherboard.

You should be able to go to the bottom right and right click Realtek HD Audio Manager and then reset up all your speakers from there.
