I have Samsung HE450 sound bar and a hisense smart tv. I cannot get the two to connect
Are they compatible
The soundbar works through blue tooth from my phone. But neither blue tooth or optic cable from tv
Would be nice to know the model of your TV.
Most have optical audio output. Some have headphone out.
Your soundbar seems to have both of these.
If you have go wireless than attach a BT transmitter to whichever output you have.
If your TV doesn't have any audio outputs then there is no way to connect a soundbar without modifying the TV.
