Windows 7: Dual monitor extended desktop wallpaper display issue

I'm having problems with my wallpapers intended to span the length of both monitors....

My main display is on the right instead of the left and when i use a wallpaper that spans both screens it starts on the main display on the right and spans to the left screen instead of starting on the left screen and spanning to the right. Is there anyway to fix this other than moving the 2 monitors physically or changing my main display to the left monitor?

It works fine if i make the left monitor my main display but i use the right monitor as my main because it has internal speakers and if it doesn't get any signal it goes to sleep muting the sound.
