Audio over HDMI with nvidia-xrun on Lenovo Y720

Hey, I have a Lenovo Y720 with a GTX1060 using the proprietary nvidia drivers. To connect the laptop with a TV I use nvidia-xrun and start plasma via

 nvidia-xrun plasmashell 

which works nice, except that I cannot switch audio output to HDMI.

A search lead me to this.
When I run these commands in terminal

 cat /proc/asound/cards 

does show the Nvidia Audio device, but I then cannot run nvidia-xrun anymore.
Did anyone of you experience similar problems and managed to solve them?

Thanks in advance!

Re: Audio over HDMI with nvidia-xrun on Lenovo Y720

Are you knowingly running nvidia-xrun because you have a usecase that there are times at which you want to use the intel card and other times at which you want to use the nvidia card?

If not and you unconditionally want to run the nvidia card, remove nvidia-xrun and set up Optimus instead: https://wiki.archlinux.org/index.php/NV … ing_nvidia

Yes, I need it to be switchabel to use Intel for low power consumption on the go and Nvidia when I'm more stationary.

Edit: Would it be possible to have different xorg.conf files and two sddm entries, one for normal, one for Nvidia? Logging in and out isn't the problem in my use case.
