So I am a bit confused and I have a huge objective I am trying to meet.
So I have a brand new 65" LG smart TV, Comcast cable box(plugged into HDMI 1), an xbox 360 (plugged into HDMI 2), and a Google Chromecast (plugged into HDMI 3[arc]). I plan on buying one of those brand new Smartcast Vizio soundbars to my setup (or whatever other brand that has Smartcast technology), that way while in conjuction with using the google chromecast, I'll be able to use verbal commands over stuff I can stream using my Google Home setup. I digress... So anyway, here is the main question......
Buying this new soundbar will come with an optical cable, and since all three of my HDMI ports on my TV are taken up already, and if I plug this soundbar system into the optical port on the back of the TV, will I be able to get the soundbar to work on all three HDMI switches?
For instance, when I walk into the living room and turn on my TV screen and soundbar on, will I be able to have sound from my cable, xbox, and chromecast coming through the soundbar system? and if so, is it like an automatic function when I switch from HDMI port to another HDMI port or do I need to also cycle through outputs on the soundbar itself? OR, can I just connect the soundbar via optical cable and switch the audio settings on my TV over to something else?
I apologize for not providing any model numbers or anything, just know that its all brand new equipment, there are 3 HDMI ports on the TV that are all currently being used, as well as an unused optical input, and the soundbar will have HDMI and optical ports as well.
Thank you and I hope someone can help...
