Very disappointed with 2020 Samsungs sound output. We have two TVs - UA43 and Q55. Both have major issues with sound output. Neither can control volume when using optical interface. Neither has normal analogue audio output (this is the worst idea ever for a TV). Neither has headphone jack. Neither can stream audio out over wifi or bluetooth. Stuck with earc which requires me to buy a bunch of new expensive hardware, can't control volume and often doesn't work. Will try to return both TVs and will never buy Samsung again.
