I just bought a Sharp HT-SB250 soundbar for my 65'' LG Smart TV. The soundbar only has RCA inputs but my TV has no RCA outputs. Would a cable with RCA on one end and HDMI on other work or do I need some kind of adapter?
If you can find such a cable give it a shot but since RCA connections are analog and HDMI is digital, more than likely you will need an active adapter. Can't recommend any though since I haven't seen an RCA output device since my childhood days.
