I have a ASUS GL702VM-GC143T ROG Strix laptop with an GTX 1060M GPU. Under Linux (I usually use Gentoo but same behaviour with Xubuntu) when I plug the HDMI cable from my TV into the laptop the display shows up but no HDMI audio device is discovered. Under Windows 10 the HDMI audio device shows up when the HDMI cable is plugged in.
With the HDMI cable connected while running Xorg no HDMI audio shows using lspci and the ALSA module snd-hda-codec-hdmi never gets loaded. I have tried the setpci method to rescan the PCI bus but it doesn’t make any difference.
Kernel: 4.13.10-gentoo, NVIDIA driver version: 387.12
At the moment I can’t think of anything else to try and am presuming there is a bug which is stopping the GPU from ‘switching on’ the HDMI audio part.
Thanks in advance.
