Z170MX Gaming 5 Audio problem

[Ritchie]

Components:

• Z170MX Gaming 5
• Intel Core i7 6700
• 32GB(2x16GB) HyperX DDR4
• 2x 256GB Crucial SSDs
• 2TB Western Digital HDD
• EVGA GTX980Ti
• Windows 10 64-bit

Z170MX G5 contains the ALC1150 Realtek audio chipset. You get the Creative "look at how many buttons I have" suite too. Manual and online states install Realtek first then Creative (I didn't want it anyway). A clean and fresh install of Windows 10 goes on works fine. I begin installing drivers network, storage etc. I then move to audio I do as the manual states and install Realtek driver first. Asked to restart and no startup sound. So looked in the taskbar and it say everything is fine. It isn't so I look in playback devices and Windows has already diagnosed by HDMI outputs on my GPU with HD audio and added them but the Realtek is no where to be found.
Windows did not find it and Realtek's drivers didn't find it so I take a punt at Creative having the final piece of the puzzle. Install, restart, nope. Same "I'm fine response" but definitely not. So I uninstall the Creative drivers, restart, uninstall Realtek drivers, restart, install nVidia drivers. Graphics now working properly but sound is obviously not still.
Next stop Realtek. Realtek brag about how wonderful the chip is but Google shows the real situation. Many posts about it not doing something (eg 5.1 or DTS after updates) but none about it not working so I assume its my drivers from the OEM DVD and download from Realtek. Install and restart only to be greeted by the same "I'm fine" message which is clearly not true.

I'm not a newbie at this by a couple decades and I'm not scared of getting my hands dirty in code or hardware (both are my job). I cannot for the life of me get Windows to make a peep through the Realtek audio. Have I missed something stupid in my excitment at new kit I've exhausted my searches and am concerned I cannot see the wood for the trees.
This is my first Gigabyte board for many many years as the last one I had did not work properly either so I stayed away.

did you make it your default sound n did you try  installing thru device manager.   I personally don't use windows 10 so not much help.

The last post on that thread is correct. Thank you.
I was ready to go back to Asus by the time I posted so my credit card is significantly better off

Solution Steps:

• Go to BIOS
• Go to Chipset
• Under Audio Controller
• Disable Audio DSP
• Reboot

Audio devices with install automatically and without worry.

I even tried to do as you suggest above. But unfortunately for me, it was not possible  . My bios is already in version F20 (the last update), I no longer found this option Audio DSP. I tried to do a bios dowgrade, but it was not allowed.
I am out of audio on the computer and waiting for a new bios, that bring back the option audio DSP option, so I can disable it and test to hear if the audio will work perfectly.

It is malfunction / poor design in audio circuit in the motherboard.
We see this complain a lot of kind gigabyte motherboards
It is not driver issue
