Due to our location in rural MA, we have th choice of Spectrum cable or satellite tv; we went with DISH satellite. We bought an RCA Roku tv in April 2020, model #RTR4062-B-CA which has been working ok with DISH and Roku except for two issues:
1. An intermittent problem: when we watch some of the Roku channels like Netflix, HBO Now, Roku TV, etc, and then go back to sat tv the sound goes all weird: choppy, broken up, metallic sounds and impossible to listen to. I have tried all the methods to fix audio: on Settings, we tried all the audio settings, auto detect, PCM-stereo, dolby, dolby digital and the rest. While watching sat tv, I have hit the "*" asterisk button and moved thru all the settings for Sound Mode: Normal and all the choices, no fix. On the Volume Mode I tried: Off, Leveling, Night. Nothing fixes the choppy audio unless I turn off the tv for a while or go back to a Roku station. The problem seems to come up more when I watch a Roku channel for a longer time, 1/2 hour or more, and then go back to sat tv. But it is an intermittent issue, not constant.
2. An ongoing issue all the time: audio levels sat tv vs. Roku channels. On sat tv I can listen comfortably at a level of 18 but when on a Roku channel I need to go up to at lest 50 or more. The Sound mode is on Normal and the Volume mode is on Off. It can be disconcerting if I m watching HBO Now and then go to sat tv but forget to drop the volume: I get blasted out of the room!
My 4k Roku RCA flat screen TV has recently been having this same type of issue. For now I've narrowed it down to when I hit the * and change the audio setting to anything but normal the sound either cuts out completely or it becomes distorted. I then have to do a reset on the TV and start all over again. As well I've noticed that after being on YouTube for awhile then turning the TV off....(time doesn't seem to be a factor)and turn it on I get the same situation. Then it's back to an audio and video reset. TV is only 7 months old.
