Comme= nt # 20 on bug 10190= 0 from Alex Deucher 
Everything looks like it's implemented properly in the code to=
 enable HBR
audio.  Take a look at:
drivers/gpu/drm/amd/display/dc/dce/dce_audio.c for audio configuration
drivers/gpu/drm/amd/display/dc/dce/dce_stream_encoder.c for display stream
infoframes

Can you add some debugging output to dce_aud_az_configure() to see why it m=
ay
not be getting enabled in your case?  Specifically see if
is_audio_format_supported() is failing for HBR formats and why and see if
set_high_bit_rate_capable() is getting enabled.
