I recently done a new build, not with the same specs I have on here;
i5 2500k
p8z77-m pro
sapphire radeon 6870
I cannot get any sound through the front+back headphone jacks, realtek doesnt detect any audio devices, however i can mess around with the settings to get windows to say i have speakers+mic and 2nd audio devices plugged regardless if anything is plugged in or not. I have tried everything!

Hiyya and welcome aaron mate sure the board is hooked up right?
Otherwise drivers? or failing that a decent sound card I use a cheap Asus Xonar DG which gives excellent audio and mixing features but my next build is having the Asus Xonar DS or DX .
Another option would be one of those card readers in a front bay but am surprised you cannot get sound off the board connections?
