Hello! So I get no audio over HDMI, not only that, apparently I can’t get any HDMI audio output to show. I followed this guide but didn’t make any difference HDMI Audio on NVIDIA GPUs Kernel 4.12.13 (tried with 4.13, made no difference) nvidia driver 384.69 ################ aplay -l **** List …

For some reason, a lot of recent laptops are set up to boot with the GPU’s PCI audio function disabled. I haven’t done much investigation, but you can turn on the audio function and make the kernel see it by setting the appropriate PCI configuration bit and then telling the kernel to rescan the PCI …

This did it for me. I had to start with no nvidia modules loaded as rmmod refused to remove them once loaded. My configuration is similar to yours so the script ran without problems (other than the rmmod). Is it possible to get to a permanent fix for this in the long run? Like maybe forcing the nv…

can you specify how exactly the script needs to look? I tried using your code since my setup seems to be the same as yours but I’m getting error messages when I try to rmmod nvidia-drm …

See this for a possible cause: [url] https://devtalk.nvidia.com/default/topic/1024407/linux/nvidia_drm-remains-in-use-for-no-apparent-reason-after-xorg-shutdown-/post/5211176/#5211176[/url]

Any suggestions regarding how to automate this script so that it runs on boot before X.org starts?

Once you have the script running correctly, you could use it as a systemd service that must run before display-manager.service.

This script works for me under Ubuntu 17.10 if I run from a non-graphical terminal (e.g., tty3 by pressing CTRL+ALT+F3): #!/bin/sh sudo systemctl stop systemd-logind sudo systemctl stop gdm sudo setpci -s 01:00.0 0x488.l=0x2000000:0x2000000 sudo rmmod nvidia-drm nvidia-modeset nvidia sudo sh -c 'ec…

I’ll give that a try (the GRUB thing) and report back.

I was able to automatically have this work upon boot by using the legacy rc.local file, which is run by systemd upon boot. This is the content of the file: #!/bin/bash setpci -s 01:00.0 0x488.l=0x2000000:0x2000000 rmmod nvidia-drm nvidia-modeset nvidia echo 1 > /sys/bus/pci/devices/0000:01:00.0/rem…

I made a better workaround using systemd unit files. The service file i have created is now a dependency of getty , so i t runs before nvidia is loaded so nothing break and you only set the PCI value and rescan. Its important not to have early KMS enabled or you will have to unload the modules and…

Somebody here had the smart idea to use grub for that:
[url]75985 – [NVC1] HDMI audio device only visible after rescan
Would avoid the hassle with removing the modules and rescanning.
