Audio echo where there is an initial faint signal, supposedly through tv speaker, then delayed regular output signal through soundbar. Tv says that the signal is only coming through the soundbar. I tried changing the audio to PCM but didn't fix the problem.
I think the issue is "solved". Not really, but it seems it's neither the TV's or soundbar's fault. Turns out that there was just a professional problem at Paramount+ with streaming Dexter Season 4. I tried watching a movie through another streaming source and it ran just fine.
