Installing Sound driver

I reformated my computer, and with it went the sound driver. I do not know what sound card I have in order to find the appropriate driver. I opened the computer and looked for a sound box. I'm not very familiar with what I'm looking for in there. I saw a small box there that said foxconn, which is on the inside of where I plug in my speakers cord on the back panel of the computer. I also tried looking in the device manager but nothing is installed there. Same with DXDIAG in the run command, no sound card info is given there.
What I did see inside my computer is a bunch of stuff written on the motherboad, I assume this is the motherboard module: E210882
How can I find which sound card I have?
