I have enabled amdgpu kernel driver for southern islands GPUs with kernel parameters `radeon.si_support=0 amdgpu.si_support=1`. When amdgpu is used, then the hdmi/displayport audio is a semitone lower. Audio works properly with radeon kernel driver. I uploaded a video in order to demonstrate the problem https://youtu.be/URhOlW5zCp0 Additional info: * linux kernel: 4.20 * GPU: Radeon HD 7750 * inxi info: https://pastebin.com/LeipSnQj
