GA-Z170X-GAMING 7 NO AUDIO from Rear Panel

[Bchick1]

Hello,
I have a brand new GA-170X-GAMING7 MoBo install with i57600K and Bios update F21.
Everything works but audio. I deleted all audio driver components from Device Manager and I downloaded latest SoundBlaster 3DrconDI driver [6.0.101.1049] and installed.
I can see movement of the soundbars if a do a test on each speaker but I hear no audio from the system.

I then moved the connection to the FRONT jacks on the case and I WAS ABLE to hear the sounds.

The front panel jacks are connected onto the mobo at the 'F_AUDIO' plug position.
I have so far tried everything I know from my experience but I cannot seem to get the audio to work correctly.

If anyone has some insight your guidance would be well appreciated.

Hi,
Two places I suggest you look.

One is in the audio control panel..  Ensure the correct output is selected.  If it supports port sense, test to see if unplugging / replugging speakers or headphones (green port) is detected. 

Second place to look is in Control Panel > Sound heading.  Playback tab...  ensure your speakers has a green checkmark...  selected as the default playback device.
