Using the Gaming 9 and 7900x with F5 BIOS. I can't get any of the Creative software to open. Yes, sound chip is enabled in BIOS. It kept saying that no device was present. Can't get any sound out of the HDMI. The S/PDIF only can do stereo. I don't get it. My last Gigabyte board. The Z170X Gaming G1 had the same issues with onboard audio. Do I just have the one sound setup that never works with any motherboard? I only want to get surround sound to my receiver. Pioneer Elite SC-61. So I bought a SoundBlaster ZxR. Now sound works perfectly. I shouldn't have to get a soundcard for surround with a $500 board.
