Hello - I'm trying to install a Sony soundbar to an RCA brand television. The soundbar is the HTCT260. Connections include - HDMI input/output and analog and digital inputs. The TV has 2 HDMI (none are ARC) and red/white audio connections as well as digital output. I've tried just about everything I can imagine to setup this soundbar but nothing has worked - I can connect it via optical to the cable box, but then the DVD sound is lost and replaced by the cable box. I've tried using a converter box that takes analog from the TV and changes it to optical - no luck. The speaker output on the TV is also set to PCM. Other equipment I'm trying to connect it to - cable box and DVD - both are connected to the TV via HDMI. Bluetooth works fine on the soundbar and subwoofer - so I know the equipment is not faulty. I've tried to contact Sony - they won't help because it's an RCA tv and RCA won't help because it's a Sony sound bar. Any help would be appreciated. Thanks.
