Hello,
I dream of doing such a setup:
wl-500gp with usb soundcard.
windows laptop.

I would like to play all sounds from the windows laptop on the usb soundcard connected to wl-500gp. Is that possible to do in any way? It would work as a kind of wireless soundcard. Some drivers for windows would be needed, so that windows would think that it's a normal soundcard, but all the data would be send over wi-fi.

Is anyone aware of software that could do this? It would be great :-)
