Ten Days in hell: Audio/Video Sync Problem

[wireless]

Equipment: Samsung 60" TV UN60H6203 Samsung Soundbar HWH450 (set on D.IN) Telus box: Technicolor UIW4001 I am a long time Shaw customer and just recently signed up with Shaw. I ran the tv and soundbar for two years without even a hiccup on a Shaw Blue Sky setup. It was a quick and simple setup and I even had voice input, which is handier than I thought it would be. For the Telus setup, I had t buy a Logitech Harmony Companion remote/hub setup and Alexa (for the voice commands.) Quick and easy setup and working flawlessly with Alexa. Now, if I could watch one, single tv show or recording it would be great. In spite of several internet searches and trying just about everything i can think of, I cannot get the audio and video to sync without a great deal of trouble and annoyance. Yes, I pause and start, rewind and start, turn everything off and back on and even adjust settings through a smartphone app. It's only good until I change channels, rewind or go forward or pause or...well, anything. I am unable to follow a story or even a short news item with much success, as I am either distracted trying to fix the sound or I have just turned everything off in frustration. Why was it so effortless with Shaw and impossible with Telus? I thought they told me they have the superior system. Please help me with any ideas you have to fix this problem. My only alternative is to cancel my contract and go back to Shaw. Thanks in advance.
