I just order one sony 65X80J

Previously I using a HDMI switch to connect astro, tvbox the go thru soundbar to my old toshiba TV
and one direct HDMI from my blueray player

Now since I have 4 HDMI port, I would like to stop using HDMI switch
HDMI 1 - tvbox
HDMI 2 - astro
HDMI 3 - blueray
HDMI 4 reservce

the seller recommend me to connect opitcal cable from tv to soundbar

My question is will my TV need to be on if I would like to listen to CD via soundbar or standby mode the sound will come out from soundbar?

Thanks
