Word of advise: should anyone have these SPDIF/Optical Out issues in the future (see quoted post), the solution is to update Beelink’s firmware.
Does core elec work on Beelink GT-King Pro ?
Yes, just download the latest release and use dtb
g12b_s922x_beelink_gt_king (It does not have pro in its name, but it’s a multi-dtb that contains the dtb for both non-pro and -pro model)
Actually it contains dtb for s922x SoC revision A and B.
For future reference.
