By running an Icecast streaming server you are able to stream the audio output from Ubuntu to any client capable of playing internet radio streams.
The answer is yes. However the windows computer will have to initiate the playback.
What you want to do is set up your linux box as a streaming server. There are multiple packages that accomplish this, Gnump3D is the GNU - free and open source software that will accomplish this.
There are various GUI wrappers that help you configure and use gnump3D, in essence though anything that gnump3d plays will be streamed from your computer. Any computer on the local network will be able to play audio files stored on the ubuntu computer.
As Takkat pointed out (and I wasn't aware so +1 to him), Gnump3D is not in the repos for recent Ubuntu releases. You can go at it yourself (and if you do please make a post on the ubuntu forums and link in a comment here), or try other equivalent packages (Icecast, mentioned in Takkat's answer works well).
