How to make independent playback from one PC of different melodies to different speakers?

Question

Audio

There was a task following. I have a computer that I want to use as a sound source. There are speakers in three rooms.
Question: how can I set up the playback of different background melodies on different speakers, but at the same time manage it centrally from a computer?
Bonus: will it be possible to add +1 channel - a Bluetooth speaker, with its own melody?

Answer 1

The simplest is to use multiple sound cards. Buy which thread is cheap on the same Ali and plug them into the splitter. Then it will remain on the software side to configure which instance plays which sound system.
