[tde-users] Using external player for system sounds; how do I pass arguments?

I want to play system notifications through Pipewire's pw-play due to having some issues with ARtS (high CPU usage, volume spikes when playing multiple sounds - I'll write a bug report later), but if I just specify 'pw-play' as the player in the Knotify settings it only plays one sound at a time, I'm presuming since it's run as a foreground process. I know that you can add an '&' to the end of a command in the terminal to spawn it as a background process, is there a way to do something similar here? 'pw-play &' doesn't work since I'm assuming the file argument is appended to the end (or if the sound data is passed through stdin, idk how this works). Help would be appreciated.
