My Apollo Lake from ASRock J4205-ITX - AVR Denon X6200
firmware 1.66 : 4K - OK; 3D (Windows 10)  - OK; HD Passthrough - OK
firmware 1.72 : 4K - No; 3D (Windows 10)  - No; HD Passthrough - No

I tried with Linux :-) all fine. Hehe.

I got the firmware update tool for 1.72 from here

https://downloadcenter.intel.com/downloa...duct=95069


It's a windows tool.

I run linux/single-boot  on my J4205 htpc - Fedora 26. - 4.13.10-200.fc26.x86_64. With an AVR X2300W.

Do you need to flash this new firmware using the tool by booting windows from USB (hopefully not!), or does the kernel load the binary as a blob? If the latter which .bin did you use and how did you replace the old one in your system?

Please don't upgrade to 1.72, as Sound is as good as not working under Windows.
