Hi everyone! I tried installing hardware decoding from this link - https://forum.armbian.com/topic/32449-repository-for-v4l2request-hardware-video-decoding-rockchip-allwinner/ , but it didn't work for me. My board version is 5.1. Has anyone been able to fix this?

I tried to enable the I2S / PCM5102 service with AI, but unfortunately, despite numerous attempts, I couldn't. But anyone can use a USB audio card. Maybe someone else will figure out how to enable it 🙂 Best regards

Support for DP Alt Mode is now functional for the A7S running kernel 6.6. https://github.com/NickAlilovic/build/releases/tag/Radxa-cubie-A7S-v0.6.4

yes, i've studied the schematic well to see if that gave any clues and I have learned that it ties into the Power Management Unit. It remains that the button doesn't work on mainline kernels but does on the vendor kernel. There must be some init step or configuration that's missing.
