IIRC it depends on the chip generation - for example amdgpu does not yet include HDMI audio support on SI parts.

Then why does it support the amdgpu.audio command line option, and why does booting an amdgpu kernel with amdgpu.audio=1 sound the same as booting a radeon kernel w/ radeon.audio=1?
Hm, I thought there was in issue there still. Anyway, was just a drive-by comment, please ignore me ;-) -Daniel
In linux/drivers/gpu/drm/amd/amdgpu:
:; grep -l audio_enable *.c|xargs dce_v10_0.c dce_v11_0.c dce_v6_0.c dce_v8_0.c
:; grep -l amdgpu_audio *.c |xargs amdgpu_connectors.c amdgpu_display.c amdgpu_drv.c atombios_encoders.c dce_v10_0.c dce_v11_0.c dce_v6_0.c dce_v8_0.c
