Hello all, I am using plain linux kernel 5.2.13 with proprietary nvidia driver 435.21 on my Nvidia Optimus (UHD 630 + 1050 Ti) notebook. Nothing fancy here and everything is up to date but in order to utilize HDMI audio over Nvidia card, I have to use this fix: https://wiki.archlinux.org/index.php/NVIDIA/Troubleshooting#No_audio_over_HD... This fix works. However either I need to manually execute those commands every time I boot (this causes X to restart) or I need to make a systemd service out of them and enable it to work on every boot (I got the idea from Nvidia forums). But systemd service sometimes makes X fail to start. So I was wondering if there is any kernel parameter with the same effect which I can apply BEFORE or DURING loading nvidia modules by simply adding it to boot options. Thanks in advance -- Ali Emre Gülcü
