Try the workaround in
<a href="https://devtalk.nvidia.com/default/topic/1024022/linux/gtx-1060-no-audio-over-hdmi-only-hda-intel-detected-azalia/post/5211273/#5211273">https://devtalk.nvidia.com/default/topic/1024022/linux/gtx-1060-no-audio-over-hdmi-only-hda-intel-detected-azalia/post/5211273/#5211273</a>
for now.
Some implications met. Workaround seems to have effects/depends on ACPI,
backlight control not working, sleep/resume breaking audio, see same thread.
Most interesting issue met in
<a href="https://devtalk.nvidia.com/default/topic/1025831/linux/gtx-1060m-with-linux-no-hdmi-audio-device-/">https://devtalk.nvidia.com/default/topic/1025831/linux/gtx-1060m-with-linux-no-hdmi-audio-device-/</a>
Workaround there works on linux 4.4 but not on 4.9, turning acpi off makes
audio device appear on 4.9 without workaround.
Another green acpi hell needing kernel quirks?</pre>
