<pre>By the way, the kernel patch that you reverted in the build that fixed the
issue was this one:
<a href="https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?h=next-20171013&id=8a2d6ae1f737fd22eaeadd0dc32b85c92f239025">https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/?h=next-20171013&id=8a2d6ae1f737fd22eaeadd0dc32b85c92f239025</a>
The Arch bug discussion referenced this blog post:
<a href="https://linuxiumcomau.blogspot.com/2017/10/fixing-broken-hdmi-audio.html">https://linuxiumcomau.blogspot.com/2017/10/fixing-broken-hdmi-audio.html</a>
As you can see from that blog post, there are now multiple devices created for
HDMI. Have you verified that none of those work? You should check that before
reporting the issue to the alsa developers. It's not a bug that there are
multiple devices, since the hardware (at least in some sense) supports multiple
HDMI outputs. I don't know why the kernel creates multiple devices even when
there's only one physical HDMI connector, but this is the standard way how HDMI
audio works on Linux (it's not only Intel that creates multiple audio devices
for HDMI).
I don't know if Kodi is able to figure out which HDMI device is actually
connected to a monitor. The information about what outputs are plugged in is
available in the alsa mixer.</pre>
