GT 1030 HDMI audio working but not everywhere

I'm using a GT 1030 2G with my HP 8300. As mentioned in the Guide to the Hp 8300 I installed VoodooHDA 2.9 and AppleHDADisabler.
HDMI audio is working so far. But some (not all) youtube videos and all videos in the fotos app have no sound over HDMI (analog is working).
I'm not sure if this is a Hackintosh or Mac OS problem.

Any suggestions what to do?
