Problems running with Advance Launcher in XBMC. Command lines and arguments?

[Choppasmith]

I've attached a screenshot of the Launcher settings. It's pretty much default. I had previously tried adding --fullscreen and --windowed to the "Modify Arguments" and that just did what was expected but didn't seem to help anything. The only thing I had to change was the Toggle XBMC Windowed mode so that when I quit the emulator XBMC would pop back up in full screen (adding --fullscreen interfered with this too, but I doubt that relates to the sound).

Also yes, this a Windows 7 32 Bit Machine.
