network stream with Windows. make music in the whole apartment

[dasdoing]

I want to extend my listening room (windows) into the the rest of the apartment via a bluetooth speaker.
I tried SoundWire some time ago but wasn't realy working.
What software solutions are there?
music needs to be in sync, which will probably mean that my mains need some delay.
what are solutions for this?
