I'm trying to use the Steam Link software on a Raspberry Pi 4 with openHABian (I know it's a bit unconventional but it would be great if I could use my RPI for multiple purposes).

When connecting to the computer, it's stuck at the 'tips screen'. I've tried serveral posible solutions like running 'rpi-update', Comment out vc4-fkms-v3d in /boot/config.txt, switching the HDMI port that's being used. This doesn't seem to work.

In the log on my host PC, I can see that the error message "CLIENT: OMX_Init() failed: -2147479543" was being spammed in the log. It's also the first and only error type I can find in the log. For what I can understand OMX is a video player that steam link uses. But I can't find the meaning of this error.

Is it possible that I should install something else that OMX needs to have? Or did anyone else bump into this problem?
