I have a LG TV model 43LF5400 and want to connect to Bose solo 5 sound bar. I can’t figure out how to get them connected. My tv doesn’t have Bluetooth or wireless capabilities. It also doesn’t have a digital optical output. The TV has the following ports: audio R, L/mono, Pr Pb and video ports. I don’t know how to connect them to the sound bar. It’s connection options are aux, optical or coaxial. The sound bar only came with a optical output cord. Any help would be appreciated. Thanks!
