_Simultatous_ audio output from different sources is a completely different topic. You should have told what you want to do right from the start, as this is outside of the scope of this howto.
In short: Alsa has exclusive access to the device, so what you want is not possible unless you can live without passthrough.
If all you need is to have spotify work while Xbmc is running(but NOT playing), then disable "keep audio device alive" in Xbmc.
For simultatinous output, you'll need pulseaudio, but you'll lose HD audio passthrough support.
