Chiaki is a ps remote play client for linux, that is used to stream your playstation to your whatever client you have it installed on.
It's extreamly usefull to get audio from your playstation to fx your pc, the only “downside” is that you need your playstation controller connected to your pc. So sometimes there can be a fair bit of input delay all depending on the network connection between your pc and playstation.
It can be installed with either the software center or flatpak, the software center is just a easier way to install the flatpak package, but its all the same. https://flathub.org/apps/re.chiaki.Chiaki
