Use local computer audio-out as source possible?

[GH2user]

I have a computer located in the study with a seperate old Logitech Z100 speakerset. I use if also for like F1TVpro (multiple screens) and sometimes to watch a movie/series and would like to stream this sound to all speakers in my house. Using Homeassistant/MusicAssistant and able to access it, I can run MA-app here as well if that would help.
Would this be possible already and if so how because I can't find it?
