Play Audio in 2 locations, in Sync, For Party Using Remote Desktop

Desktop:
Windows 7 Ultimate x64
Creative X-Fi Xtreme-gamer
Logitech Z-5300e
300Mbps Wifi connection with -10dBa signal

Notebook:
Windows 7 Ultimate x64

120Mbps Wifi with -58dBA signal in garage

Hi, I'm hosting a party this weekend and want to control, with my notebook, the music playing on the desktop downstairs while simultaneously playing the same audio on the laptop from my garage. In the past, I have used the laptop to control the desktops audio from upstairs using remote desktop and selecting the option, "Play on Remote Computer." Which works well because the Z-5300e audio system is able to be heard through the house. But not the garage..... I was hoping to use this feature this weekend to play the same audio simultaneously in both locations. However I just realized there was no option to, "Play on Both Computers."

Is there anyway to accomplish this?

Also, it's not required for me to be remotely logged in, it's just how I figured I could somehow do it. I would even prefer if there was no remote connection since I'm sure people will try to play Youtube music videos from the laptop which doesnt work well when the Laptop is remotely connected.

I tried VLC player using its create audio stream wizard. It doesn't appear to do anything on any computer. I hit create stream, the wizard closes, and VLC just sits there like dumb to whatever I did in the wizard.

Also tried creating a windows shortcut using this command:

On the Laptop:

"C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" dshow:// :dshow-adev="Stereo Mix (Realtek High Defini" :dshow-caching=200 --sout "#transcode{vcodec=none,acodec=mp3,ab=320,channels =2,samplerate=44100}:http{dst=:8079/st.mp3}"

VLC just crashes. But at least now Windows Firewall asked to give VLC permission, progress I guess.

On the Desktop:

"C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" dshow:// :dshow-adev=""What U Hear" (Creative SB X-Fi" :dshow-caching=200 --sout "#transcode{vcodec=none,acodec=mp3,ab=320,channels =2,samplerate=44100}:http{dst=:8079/st.mp3}"

VLC says something like invalid sound device


To see if anything has happened while the laptops VLC player was sitting dumb when it was supposed to be doing something, I connected the desktop VLC to the laptops supposed streaming address, http://192.168.180.44:8079/st.mp3 and the Desktop VLC crashes.

The only thing VLC seems to be good for is crashing. Even when following guides exactly, on both computers.
