Vista Wireless Audio

I've been using a Linksys WMB54G Wireless Music Bridge to stream audio
from my WinXP
system to a remote home theater setup. I want to move to Vista, and,
after waiting for months,
Linksys hasn't been able to come up with drivers for this device with
Vista. There's a lot of
discussions about workarounds on a Linksys forum, but I haven't been
able to get any of them
to work at all/very well.

Can someone recommend a wireless audio solution that works with Vista?
I'd like to stream
as many types of audio as possible from the PC - MP3's, internet
radio, etc. I'd like it to support
802.11g or better, since wireless range is an issue here ...
