kernel tries to enable nvlink every second, audio stutters

[sluedecke]

I have a recent ASUS ROG Flow X16 running with arch linux and I have set it up to use nvidia-exec in order to keep power consumption in check.

The machine starts fine with the gGPU disabled and I can use nvidia-exec for all games/applications.

But: right after booting with the dGPU disabled, the nvidia-dkms kernel module repeatedly (every second) tries to enable nvidia-nvlink. Every attempt makes my audio stutter, every attempt fails.

When I do nvx on, stuttering stops and so do the error messages in the journal. I can then turn the dGPU off again with npx off and everything seems to be perfect.

While I write this, I have the gut feeling that this is probably an issue with the nvidia-dkms module, right? Or is it something you can fix with small effort?

not sure if you're still having this issue given the date..
however, if still unresolved, the first step i recommend you check is if nvidia-persistenced.service and nvidia-powerd.service are disabled with systemctl status.
