Heyo! I’m aware that this is being worked on, just wanted to give a heads up to the NoMachine team (and anyone browsing): Ubuntu 22.10 (Kinetic) has now officially removed Pulseaudio from the standard install, and is going to be releasing with Pipewire out of the box for all audio.
Relevant thread: https://discourse.ubuntu.com/t/pipewire-as-a-replacement-for-pulseaudio/28489/2
Relevant NoMachine KB feature request for anyone coming across this:
