@khelpix

what info do you need tell me?

I just link the thread where you can read how to format properly the code and put the only single line of code to give every info we need…

Anyway…

@khelpix

video-hybrid-intel-nvidia-prime 2020.11.30 false PCI

So this is laptop with Intel + Nvidia card right? try editing the file /etc/udev/rules.d/90-mhwd-prime-powermanagement.rules and put a # after the line # Remove NVIDIA Audio devices, if present,should be like this

#ACTION==“add”, SUBSYSTEM==“pci”, ATTR{vendor}==“0x10de”, ATTR{class}==“0x040300”, ATTR{remove}=“1”

save and reboot,the audio should work now.

[khelpix]

■■■■ this is awesome, this was the solution ->>>>>>
sudo nano /etc/udev/rules.d/90-mhwd-prime-powermanagement.rules

[khelpix]

@XRaTiX

#ACTION==“add”, SUBSYSTEM==“pci”, ATTR{vendor}==“0x10de”, ATTR{class}==“0x040300”, ATTR{remove}=“1”

just set this
