I can try it, just to check that the cable/port combo is ok. I'm not sure how would that help - the reason I'm using the edge kernel is to use the upstream/Linux kernel implementation and the implementation may not be the same as the one provided in the outdated vendor image.

tl;dr; You need to fix the driver code similar we do it here https://github.com/armbian/build/tree/main/patch/misc I tried this: https://github.com/albertogviana/YT6801 (but tuxedo v1.0.30 might have this already fixed) https://paste.armbian.com/xeraretaxu.diff I fix the most obvious errors, but don't have time to deal with this code. Some intermediate or old kernels might be missing matched headers. They are present at latest kernel (tested). BTW, it works for me: khadas-mind:Downloads:% sudo dpkg -i tuxedo-yt6801_1.0.30tux4_all.deb Selecting previously unselected package tuxedo-yt6801.

I suggest to confirm first that it works with the vendor image, just in case. If you boot the vendor image you could also gather some info, like aplay -L, etc.

@Dantes Board is now supported, i advice you to wait next nightly release for fix some issue on cpufreq driver. If experiencing some issue please report on https://forum.armbian.com/forum/85-rockchip/

@Ducdanh Nguyen, can you contact seller of your tv box and ask if they can provide firmware (or "firmware update") for it?
