No Audio over HDMI on GTX 1060

On my ASUS Strix gl502vm-db71, which has an Nvidia GTX1060 in it, I get no sound over HDMI when connecting it to the TV or external monitor.

The on GPU sound card doesn’t even appear to exist…

It seems we might be having the same issue. Did you ever find a solution for it?

Nope, I still have it, and nvidia doesn’t care. :)

try to desactivate your onboard audio in the BIOS .

Do you have any ACPI errors on your logs? I’m getting this which seems suspicious since it mentions HdaDsp:

ACPI Error: [PPMS] Namespace lookup failure, AE_ALREADY_EXISTS (20170531/dswload-378)
ACPI Exception: AE_ALREADY_EXISTS, During name lookup/catalog (20170531/psobject-252)
ACPI Exception: AE_ALREADY_EXISTS, (SSDT: HdaDsp) while loading table (20170531/tbxfload-228)
ACPI Error: 1 table load failures, 14 successful (20170531/tbxfload-246)

Deactivating the audio card in UEFI leaves me with no audio. Nothing is listed under aplay by then.
