Question On-board sound card seems to be dead after GPU installation ?

[frozensun]

Hi guys.
I was using my new PC via displayport on motherboard (Z690-f strix) and sound card was working normally (Realtek audio console).
I did installed graphics card to motherboard, turned on the PC and noticed in lower right corner red X on sound.
Windows installed display drivers automatically, but still I don't see any device except nVidia High definiton audio.
I reinstalled audio drivers, no luck.
There is no even sound card in device manager and when lauching realtek audio console I get an error:
"Realtek Audio Console doesn't support for this machine.
But it was working normally prior to graphics card installation,
What happened,what to do?
So now even when I removed the graphics card, sound card is dead.
What coild possibly kill some electronic component on PCB around sound chip?
PC was off the current all the time when GPU installed, I even plugged off DP cable.

Yes, >USB Audio Controller Enabled.

That is not correct setting for enabling integrated audio.
This setting allows connecting external USB audio.

Try updating BIOS to latest version.

Is the motherboard brand new? If so return it to your retailer as dead on arrival. Otherwise if it is still in warranty RMA?
