USB-C Dock with HDMI no output

[coolmule]

Using a USB-C dock with a new pinebook. The other ports on the hub function. However there is no HDMI output.

When examining the "display configuration" GUI window (KDE) there is a second window called "DP-1" when the dock is plugged in, irregardless of whether a HDMI is plugged in or not.

When inserting the USB-C cable the other way around, the Display Configuration does not show any extra monitors irregardless of HDMI. It does not display the "DP-1" window in this case either.

HDMI on the USB-C dock works when connected to other devices

I updated Manjaro and HDMI is also stopped working for me.
It was working before the update.

I also have no sound via USB-C to HDMI adapter to my TV. Haven't looked much into it yet since I can just plug my speaker system via headphone jack
