I wanted to see if others maybe had this issue and had some fixes. My ARC (setup with 2 subs and 2 play 1s as surround speakers), occasionally has kind of an echo/phasing effect.
I notice it most often when watching Last Week Tonight (which is in Dolby 2.0), where partway through most episodes, it will start to sound like Jon is a football stadium announcer with the audio instead of being from the front speakers, starts to also have a slight echo in the surround speakers.
Recently, however, it has done it on music playback from my computer library (I have the surrounds setup on Ambient), where the echo effect happens again.
With HBO (native app to my Vizio TV), I can just stop the show and restart it. With the music, that didn’t work, so I restarted the speakers.
But I can’t figure out what might happening, or if there’s likely a specific hardware issue that might be causing the issue.
Any thoughts you all have would be appreciated. Thanks!
