USB-C only storage and ethernet?

Has anyone tested the usability of the USB-C port on Ubook? I tried with an ethernet adapter and a multiport adapter. I was only able to make ethernet and external storage work via this interface. HDMI and sound were not available, at least not in my case.

HDMI is work on my ubook USB-C port

Try updating your software. Maybe somewhere the drivers are conflicting or not working properly.

Everything is on the last version. Is there any newer BIOS available perhaps (mine’s “from factory”, from around a year ago)?
