Hello yesterday I built my HTPC with an EVGA stinger board. Pretty cool, it fits perfectly into the Streacom F1C Evo chassis... Also I can confirm now that the Noctua l9i fits onto the stinger as well as into this chassis :)
 
My only problem now is that I can't get audio over HDMI to work and I am out of ideas. I did a clean install of Windows 8.1, I tried to install the latest Intel Graphics Driver. I tried to connect the HDMI cable directly to my TV instead of the Bose Lifestyle entertainment system etc. ! I even disabled the onboard sound card to avoid any conflicts. But it always tells me that the are no audio devices installed.
 
In the device manager everything is ok... I can also see the HDMI Devices in the video sound and game controller section... but only if I enable "show hidden devices". When I click on them they tell me that there is nothing connected to it - but why? I get the video perfectly fine over my TV so yes HDMI is definately connected and working. But I am not sure what I miss here? Searching for problems with Intel HD Graphics and HDMI I find some issues but none of these fits mine...!
 
Maybe someone of you has had a similar problem or can help me out?
 
Thanks in advance,
Oliver
 

After several hours of more testing I am pretty confident now that this is a bios issue. Is anyone able to check if he can get HDMI audio output over the integrated graphic HDMI port of this board?
 
I tried to check the different bios options but I don't find anything related to this... please can you guys look into that - since I have built a HTPC with your board I really need the integrated HDMI audio output to work otherwise the board would be totally useless to me :(
 
Thanks again,
Oliver

Hmm hope this will be fixed in a future BIOS update

Hello Jacob,
 
yes I am using the onboard HDMI graphics port. The audio chip is disabled, since I don't need any audio on the audio ports. I am just using the audio over HDMI. The strange thing is that if I set the graphic BIOS mode to Legacy Mode, all is fine. As soon as you switch the option to UEFI mode, the audio is not working anymore -> no devices for HDMI audio are found (in device manager you can see that they are hidden and say - hardware not connected...).
So this was really haaaaard to find because at beginning I switched all BIOS to UEFI mode. Not sure if this bug is related to the onboard graphics card from intel or if its a bug in the stinger?
 
Kind regards,
LD

Hope it's k

I was able to resolve this by manually installing the Intel Display Audio driver as in these steps:
 
Download the "Intel HD Graphics" driver for the motherboard here:
\Downloads\Z87_Intel Graphics v15.31.9.3165\Intel Graphics v15.31.9.3165\Intel® HD Graphics Driver - 64 Bit\win64.zip needs to be unzipped
 
Then right clicking "High Definition Audio Device" under device manager and installing driver by selecting the win64/DisplayAudio folder.
 
The audio drivers aren't installed when updating the display drivers for whatever reason.
