According to another post audio passthrough is enabled on the latest beta, so today I installed it on my Shield TV and still don't get any audio passthrough and instead it looks like channels is doing the decoding then passing to avr as multi-channel.
My media is in H265 mkv containers and play fine except audio is not sent for decoding via receiver. Is the feature not actually working then for local content?
If I use Plex or Emby for the same content they pass the audio through and my receiver decodes it so not an issue with the container format
