In my home network I have laptop and desktop computers. Speakers are connected to the desktop, but I want to manage music from my laptop. Is there any other way to redirect sound from laptop to desktop?
Get rid of your default player and install Foobar or anything alike with remote-control plugin. It is quite a normal linux practice for lots of nix players like mpc; and now it's web 2.0, home easy networks and windows.
NAS can do that and they claim there is a way to make it run under Windows.
I haven't used it there, but I guess the setup will be hairy. Also, NAS seems pretty much dead after pulseaudio entered the stage.
