Summary: hdmi/displayport audio is a semitone lower when amdgpu
driver is used
Product: DRI
Version: unspecified
Hardware: x86-64 (AMD64)

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
