I have a 40 inch sony bravia it doesnt have a onboard pcm mode. So I have my cable HD dvr cable box hooked to the soundbar with the Digital optical cable and its running in pcm mode on the box and hooked to the tv via hdmi. My Sony Bravia Blu ray player has a orange digital coaxial port so I run that to the sound bar and hook it to the tv via hdmi. My tv only has one RCA hook up 2 hdmi ports and it has a toslink port but my sound bar wont run off it since it doesnt seem to have an onboard pcm mode. Tv model number is KDL 40R250B Sony Bravia. So Should I keep this set up or try to rewire something. The soundbar only has the toslink the Coaxial and a 3.5mm to red white rca. Its also a Vizio 29 soundbar model number dont have handy.
