To answer the OP - it depends how you've got the TV and soundbar connected.”
If both the TV and the sound bar had HDMI connections that also support ARC then yes. But so far we don't know what the TV model is, and we do know for sure that the Samsung J355 doesn't have a HDMI - or at least it doesn't according to the Samsung web site - so ARC is out of the question for that product anyway.
The J355 has Optical which will most likely be a fixed level signal from the TV. It also has a 3.5mm headphone jack but again (a) we don't know the TV model so can't say if that has a suitable output, and (b) even if it has it would still need checking whether the headphone volume is driven by the TV volume slider or from a separate sub menu.
As it stands then, until there's more info there's not a lot that can be added without venturing off in to a lot of speculation.
