There is a definite issue with this specific episode on the Roku platform.
Having binge watched nearly every episode of the entire series, all the rest are working fine. This one episode, though, has almost no dialogue. You can hear the background music just fine, but even though the actors are clearly speaking their lines, you don't hear that at all. This is particularly obvious in the first scene.
In the second scene, you can barely hear any of the actors' voices. It sounds more like they are whispering and you can't make anything out.
All the episodes before and after do not have that problem--so far, 12 seasons worth.
Thanks!
