Both my issues resolved, thanks, Goose.
I record OTA with a Tablo and there is a setting for “Surround Sound” that was not checked, so it was only passing 2 channel files to MCEbuddy. “Hissing noise” must’ve come from the 2 channel downgrading on the Tablo side.
FYI on the Best Audio scenario I encountered however:
Here are the logs (I think anyway) from a test of the Best Audio setting. In hindsight I should’ve used the same exact file, not sure why I didn’t, sorry!
Killing Eve S03E08 >> “Select Best Audio=yes” and it changed to 2 channel
Killing Eve S03E04 >> "“Select Best Audio=no” and audio remained at 6 channels
