My Samsung TV: QN49Q80TAFXZA
My Samsung Soundbar: HW-Q900T
At no point is there a TV + Soundbar option. Connected via eARC using cable the soundbar came with.
Hi I just fix it a few hours ago , you have to update your tv , maybe it’s already updated but the soundbar need to update it too, so I updated the soundbar in the app SmartThings and it that was it .
