Soundbar: best way to connect it ?

I have:

- Samsung PN50B540 TV (Aynet)
- Cable Box
- xbox 360
- Soundbar Sony HT-CT150

Option#1:

SoundBar -- HDMI -- TV
Cable BOX -- HDMI -- TV
Xbox360 --HDMI -- TV

With that setup, I can choose to have the sound of the TV or the soundbar


Option#2 (the recommended setup according to the soundbar documentation)

Cablebox -- HDMI -- Soundbar
Xbox360 -- HDMI -- Soundbar
Soundbar -- HDMI -- TV

With that setup, the sound is always through the soundbar, but it's a pain to switch remote/inputs


Anyway, any other advantage/inconvenience with both setups I'm missing ?
