Intel NUC10i7 Front Panel Audio Not Working

[K2]

I have a new Intel NUC 10i7 that the front panel audio currently doesn't work and has been 'hit or miss' (mostly miss) with working since I got the machine at the end of October. 

• Running Windows 10 Pro 20H2
• 32GB RAM w/ 512GB Samsung 970 EVO SSD
• I've had both BIOS versions 0046 and 0047 - neither have worked reliably or even repeatedly
• I've always had the yellow exclamation mark on the 'Intel(R) Smart Sound Technology OED device
• There has never been a Realtek device in the Device manager
• I've reinstalled both the Chipset Manager and the Management Engine
• After IDSA does any updates it's goes in to an infinite loop of saying their is a Realtek driver update, installing it, rebooting, and saying there is still a Realtek driver update.
• On occasion (less than one in ten) I've gotten the front panel audio to work once with a driver installation from the RealTek website when IDSA loops as detailed above.
• There is no RealTek control panel application 
• I have the HD Audio option selected in the BIOS

I would appreciate some help in figuring this out. I had an NUC5i3 for over 5 years and it was rock steady. I was expecting the same from the NUC10 but now I'm having buyers remorse.

Thx

Victor -

Thanks for the reply. Attached is the SSU report and several screenshots of the Intel SST OED status from the device manager.

Another data point worth considering - this PC has never booted in less than 90 seconds. From the very first day I had it. My five year old NUC5i5 would boot in 20 seconds. So there is something obviously not right. 

Thank you for your assistance,

1. Cold reboot - no change

2. Re-install Realtek drivers - no change

3. BIOS update via power button method - got an error message about an invalid flash image when I copied the FN0047.cap file to a USB flash drive.

Update on #3 (above) - after actually reading the instructions and downloading the correct BIOS update file I was able to update the BIOS using the F7 power-on recovery method.

Unfortunately it made no difference. I still have no audio. I even tried reinstalling the Realtek drivers following the BIOS update.
