Windows 7 - Remote desktop + remote audio

I have 2 laptops, both connected cable+wifi to a 4port router. Main PC is Windows 7 Home Prem x64, the other which is now a dedicated jukebox, XP Pro SP3 x86.

Both laptops also have minijack-to-phono leads from their headphone sockets to different inputs on the back of the same amplifier. So all computer audio comes out of the home cinema.

I remote desktop without problem, but when I work in another room (and unplug Windows 7 from home cinema) and open music (on XP), I can't hear it from the hifi - only the Windows 7 laptop's speakers.

Is there a way to play audio remotely, and not have it sent via wifi to play locally?

Little help please?

OK, so I should clarify that I have tried (it doesn't work for my desktop shortcut) but:

Start --> Search "Remote" --> Open --> options --> local resources --> "play audio remotely" doesn't work. 'Play locally' works, but remote doesn't.

Help, please!

Solved it. M$ hotfix available KB969084 (XP SP3 only)
