            Bug ID: 109338
           Summary: hdmi/displayport audio is a semitone lower when amdgpu
                    driver is used
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: thanosapostolou@outlook.com

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
