To output audio over HDMI you need to output a video signal as well.
This creates additional pressure on the memory bandwith because the
hardware now needs to handle two video signals instead of one.
You need to connect your screen to the output of the amplifier to avoid
this.

I have rx480 which I connect into 1920x1080 pc screen via DP and audio
into external amplifier via HDMI. This causes rx480 to raise the
memory speed to 2000 while doing really simple tasks like watching
youtube. I really dont need thatkind of speed for memory. And I am not
aware that it's possible to change between 300mhz 2000mhz memory
speeds, but gpu supports this in steps which would be really great for
memory too. I only need the audio data submited to the amplifier. Is
it possible somehow to form a patch that it somehow recognizes my
amplifier and understands that I am sending audio that I dont
need/want it to max the memory speed? I would be really happy for such
patch for personal use. If it's too hacky to be merged into upstream.
