ATV: Crystal-HD Card not working

Hi There
I have some Problems with my Apple TV 1G running OSMC 2017.10.1

Ive installed my Broadcom BCM70015 Video Decoder Card but i Cant enable it! – the Option in settings->Playback are greyed out so i can´t interact with it and enable it

I think the Card is Working because ist listed in a pci listing as 02:00.0 Multimedia controller: Broadcom Corporation BCM70015 Video Decoder [Crystal HD]

Is there Any Bug or Workaround?

It’s only supported in 2017.01-1 and earlier (Jarvis).
It’s intentionally greyed out however, as the decoder is always used if present.
