Purchased Harmony 650 remote & programming seemed to be fine until I tried adjusting volume. Sony TV 40W3000. Volume bar went presented by Harmony went from 0 to 30, but 30 was moderately loud and was unable to make it any louder. Spoke with Harmony tech line and while on the phone with them the tech reset some stuff on his end and then the sound disappeared totally! No clue nor did the tech. The TV and cable remotes both show sound level going up and down but no sound at all. Same for all channels and all levels. Playing Netflix thru BluRay works fine - sound is ok. And picture is good.
So, I've checked the basics - it's not muted, sound is set to TV speakers. Called cable company and they didn't find anything - tried alternate HDMI input for cable box input but still no sound. Did factory reset and still no sound.
Frustrating - you bet! But now what? Wondering if anyone has recommendations? And whether if I switch speakers to external audio whether that might work (don't have any such speakers to try now).
