I also doubt that this is true. Where is that spec? I have tested quite a f=

GPUs (Intel with i915, Nvidia, r600) and all of them had proper HDMI audio/=

support, which was completely unrelated to HDCP.

Even on Windows HBR audio does not have anything to do with HDCP. I am not
using HDCP there either and my RX480 properly passes all audio formats to my
AVR on Windows.
