So I have an old ASUS K46CM laptop running Xubuntu 20.04, with a functioning speaker but defunct audio jack. I've disabled the audio from BIOS now to deal with it.
This presents a new problem: I can no longer hibernate nor suspend this laptop. It generated an error that said:
0000:01:00.1: can't change power state from D3cold to D0 (config space inaccessible)
I googled around and found someone with a seemingly similar problem and a working solution: disable the device on boot with a custom udev rule, from this link below:
https://forums.developer.nvidia.com/t/kernel-5-6-system-freeze-when-resuming-from-suspend-or-hibernate/121630/21
The udev rule in question:
cat /etc/udev/rules.d/10-remove-nvidia-audio.rules
ACTION==“add”, KERNEL==“0000:01:00.1”, SUBSYSTEM==“pci”, RUN+="/bin/sh -c ‘echo 1 > /sys/bus/pci/devices/0000:01:00.1/remove’"
Except that it didn't work for me.
The problematic device:
01:00.1 Audio device: NVIDIA Corporation GF108 High Definition Audio Controller (rev ff)
... is still listed in my lspci output after I put that workaround:

Perhaps I've missed something? To be honest this is my first time dealing with a problem involving udev rules.
Thank you in advance.
