Hey @popcornmix @vanfanel , with audio=off I just deactivate the brcm sound card, what do I have to deactivate vc4-hdmi soundcard? How can I add a present but empty dmas?...

@6by9 Yes this is as I tried, but I deactivate brcm soundcard and not the vc4-hdmi

I am running a 4.9 kernel, and now I understand. The 'audio' parameter hasn't been implemented in 4.9. So I have to look for another solution or update the kernel....
