No audio over DVI port with amdgpu (RX 570) - remove audio restriction
As I have to use the DVI port to connect to my TV (via DVI->HDMI cable) because there is no direct way to change the pixel format (Full RGB output required to fix a wrong color problem with my TV).
The same cable works fine with Windows 10 (there you have change the pixel format even if the DVI port is used in the driver settings, but this could be done for HDMI as well). Sound is working fine with Intel or Nvidia gfx on Linux too via DVI ports.
Please remove that restriction - it should not even require an override, but I could live with "amdgpu.audio=1". I think this worked with my older Radeon gfx cards.
Technically single link DVI is the same as HDMI. So why should audio detection not work the same way?
