The set-up: (new) LG oled65B7A TV , Roku Stick Plus with Sonos PlayBar, paired Play 1's and a Sonos subwoofer. Audio wise everything works fine (audio and video) thru cable box and Roku Stick+ to watch Netflix or any of the other streaming channels EXCEPT for when I try to watch any Amazon Prime videos. Then suddenly no sound comes from the Playbar? I've reset the TV changed various sound inputs but not luck. For whatever reason sound does not come thru when watching Amazon Prime.
Prior, with the same setup but a different TV all was working fine, sound from Amazon Prime video's was not an issue.
Any ideas on what may be causing the sound issue with Prime video watching? I've spent hours trying to figure it out and searching online. Thanks!
