Problem connecting a Soundbar and Speakers

[TG1730]

Hi there, I use a Sony STR-DN1080 A/V system to connect my Projector, surround speakers (wired) and my Sony TV (KD-50X75WL).    Can I add a Soundbar to this configuration and keep my surround speakers as well?

There are two outputs on the A/V Receiver - Output A goes to the TV, output B goes to the Projector.  How do I add the Soundbar?      I would also like to retain the rear (wired) speakers as well; is this possible?   

Thank you again for any guidance!

I should add that the eARC HDMI slot on the rear of the TV is currently connected to the A/V device but this is the recommended port for the Soundbar hence my question how and where could I connect my Soundbar?     Tony

I'm sorry, but AFAIK you cannot connect two HT systems to the same TV and moreover let them work together. You should opt for one or the other
