I use eArc, but have tried plugging straight to my Atmos soundbar. DD5.1 still doesn’t work.Same issue here. I use a splitter to get the optical audio needed for my system. After the update, 5.1 audio only works from the YouTube app and Infuse apps.
Seems to be an issue only for users that don't use HDMI straight into their receiver...
They need to fix this ASAP...
