Okay so I have a computer I recently built and I am having some difficulties with the Audio. I have a RAIDMAX Cobra case with front audio ports and Asus M5A99FX Pro R2.0 motherboard with 8-channel audio. I have downloaded all the drivers that asus says to download, I have downloaded all the drivers that are compatible with this motherboard and yet I still cannot use my MIC or Headphones in any of the ports. (Front or Back) There are options in my BIOS to set the Azalia On-board audio from SPDIF to HDMI, I've tried both settings. Also, I have the option of setting it from AC'97 to HD, I also tried both. I am not sure what settings I should be using or if my audio ports are bad... Please this is a bran new machine! I need help badly. Thanks!

PS My HDMI cable on my graphics card works for audio is that interfering? I have tried unplugging it and using just my VGA cable.
 
Video cards often contain a built-in sound chip for HDMI audio. It often get set as the default audio device when you install the driver.

You need to open the Windows Control Panel and navigate to the Sound section. There you can manage multiple sound devices. The motherboard uses the Realtek ALC892 8-Channel High Definition Audio CODEC.

Yea I tried disabling the HDMI audio and picking my headphones and microphones as the default devices but they wont do anything. The only way I can get my devices to appear as plugged in is when I use my Realtek Audio Configuration UI and choose AC'97 as the Front Panel audio mode and I can get my front panel to actually appear as if I have something plugged in (even if there's not) and no audio is displayed even though it says there is. not sure what is going on
 
HD audio was the successor to the AC'97 PC audio standard. This occurred in 2004, so you would need to be using a very old case or very old motherboard to be using AC'97. Most new cases include cables for HD audio and AC'97, but you usually don't need to bother connecting the AC'97 cable.
