Is it possible to use HA instance as Chomecast

Hey,
currently I’m running HA OS in a virtual environment, but I want to install it ‘on the bare hardware’ in the future (because I’m struggling with autostart configuration, but that’s another topic)

So is it somehow possible to (chrome)cast to the device where HA OS is installed on, through any Add-on/emulator or anything, that I can stream e.g. Spotify or YouTube videos to a connected monitor of the HA x86 system?
Or is the sort of terminal the only thing, the device with the OS will ever show?

You posted in the operating system section, and the answer is no for HAOS.

You possibly could by using, say, proxmox and running another os for receiving casts.
