Without model numbers you won't get an exact answer.
If your TV has a single RCA audio jack labeled digital or coax out then and your soundbar has a stereo analog audio input you would need a DAC to converter digital to analog.

You may have to turn the audio output on, the TV speakers off and change the audio output type in the TV menu to get it working.
