ASRock Z68 Extreme3 Gen3 Onboard Audio Doesn't Work

Hello everyone. I just build a new PC using an ASRock Z68 Extreme3 Gen3 motherboard. I updated the BIOS and all drivers, and still can't get the onboard audio to work. I've tried a simple set of 2.0 speakers and a headset. Both work on my other PC. When I plug the speakers in, it doesn't seem that they're being detected. Control Panel -> Sound shows that Realtek Digital Output is the default playback device. It says nothing else is plugged in. Same deal if I plug in the headset, either to the onboard audio jack or to the front panel.

I've also toyed with the BIOS settings. Onboard Audio and Front Panel Audio were both set to Auto by default. I tried Enabling Onboard and completely disabling Front Panel, but I'm still not getting anything out of the onboard video.

If I play any audio, the mixer shows sound being played through the Realtek Digital Output device...even if I don't have any speakers plugged in at all.

I'm using an ATI Radeon HD 7850. It has its own HD Audio driver it installs. I just tried disabling that as well, and I'm still not able to get the system to pick up my speakers.

Any thoughts? All I can think of at this point is that the onboard audio is dead, but everything else on the motherboard appears to be working just fine.

I unplugged the front panel HDA cable and reinstalled the drivers again. The Control Panel now shows that my speakers are the default output device. However, I'm still not getting any audio. If I play some music or a movie and open the volume on the task bar, I see the audio levels rise and fall as the music plays. Just not actual output. Nothing is muted, and I've got the volume for everything turned up to 100%.

They're plugged into the green output jack. I can't set them to the default sound device, it says they're not plugged in. The only available device is Realtek Digital Output, which is using an output (S/PDIF) that I'm not using. Everything looks good in the device manager. I also updated the drivers to the newest version from Realtek's site. The Realtek HD Audio Manager doesn't seem to detect any of the analog ports at all. It always sends output through the digital output, and tells me that nothing else is plugged in. I've tested the speakers on two other PCs and they work fine.

I've also had this problem with the exact same motherboard. Why is this such a common issue, did they just decide to half-ass the onboard audio? Installed a third-party audiocard, luckily there was just barely enough room in my small tower for it. Also after about a year with this motherboard I can say the network adapter is starting to go, anytime the internet goes down temporarily I have to fight with it for an hour to get it back up and running, i.e. reseting network adapter, repeatedly restarting computer, etc.

Exact Same problem, What triggered it was the switching to my HDD, To a SSD, Thats the only thing I changed, And I hope i dont start experiencing the Network problems with this mobo, Like i had with the 970a- g46, So...Ive dont ALOT of research, and the only way to fix this problem is 1.) Buy a new MotherBoard, 2.) Get a soundcard
