Soundbar sound

[psalliss]

Can someone answer a question for me as reading up on Google search I'm not getting a clear answer.

If I have all devices connected to the TV via hdmi arc and then other end to hdmi arc will all sound from the TV sources including on board apps play the sound via the soundbar?

Also if connected via optical same question

I'm asking as having issues getting a philips tv to work with sound bars of which I've tried a yamaha and now a lg one and neither will work at all via hdmi arc but will via optical but on board Netflix doesn't work so getting a little confused. I'm wondering if it it's the TV and the sound format output it supports

All sorted now. Returned the Philips tv which was a shame as was a really nice picture and had ambilight which I liked. Picked up a samsung TV and all works fine with the LG soundbar. Haven't quite worked out the pass thru but not a major issue.

Not sure if was just a duff or was Philips tvs in general don't work well with arc

Thanks. To be fair to the TV the picture was really good. As good as the Samsung I've bought and I really quite liked the ambilight as the TV is just used for gaming and always on a dark room
