<pre>Graphics card: ASUS Radeon R9 270
Kernel: 5.2.9-arch1-1-ARCH
I recently had some issues with the "radeon" driver and discovered that the
"amdgpu" driver now has support for Southern Islands (SI) GPUs using the
amdgpu.si_support=1 boot flag.
Graphics stuff works great with "amdgpu" so far, however, all HDMI audio
outputs are marked as "(unplugged) (unavailable)". This seems to be a similar
problem, based on IRC logs by BCMM at
<a href="https://dri.freedesktop.org/~cbrill/dri-log/?channel=radeon&highlight_names=&date=2018-09-05">https://dri.freedesktop.org/~cbrill/dri-log/?channel=radeon&highlight_names=&date=2018-09-05</a>
which lead me to this bug report.
