I have the same problem. Install that software don’t solve anything.
Also I installed your ISO win10.wim (https://mega.nz/folder/Q9UBCAoQ#590rq3MDt82iwUMs_VJ6SQ) and Windows devices are recogniced but sound only works in the 3’5 jack audio. The HDMI never sounds.

I think that the problem is in the drivers. There are more devices that are not recognized.

We need newer or better drivers (Drivers taken from https://dl.radxa.com/rockpix/drivers/windows/ROCKPiX_driver_archive_20200904.zip)

Error%2051

Translation into english:
Windows found a problem when installing the device drivers
Windows found drivers for the device, but an error occurred when trying to install them.
This device is waiting for another device or set of devices to start. (Code 51)

Why haven’t we heard about it? Does our device have a manufacturing defect?

I got mine working by updating my Windows Display Driver. At first it wouldn’t let me do that, so I had to go to the Group Policy Editor and navigate to Computer Configuration\Administrative Templates\System\Device Installation\Device Installation Restrictions. I right-clicked the entry labeled “Prevent installation of devices using drivers that match these device setup classes” and hit “Edit” in the context menu. I clicked the “Disable” radio button, hit “Apply” and exited out.

After doing that, I was able to update the drivers. I went to Device Manager>Display Adapters>Intel ® HD Graphics. Right-clicked, hit update drivers in the context menu.

This got sound over HDMI and made the graphics function much better, too.

Yep! This worked for me! Thanks
