FireTv Jellyfin passing AAC5.1 through HDMI ARC as 2.0? - sisu - 2023-11-07

My setup:

FireTV Cube -> LG C3 -> HDMI ARC (not eARC) -> Pioneer A/V Receiver

- When playing contents with DTS -> Receiver receives and process the 5.1 signal correctly
- When playing contents with AAC5.1/7.1 -> Receiver just sees 2.0

Is there a setting that I need to toggle through the TV or FireTv or Jellyfin that would sends the AAC5.1/7.1 signal to the Receiver correctly?

OR

Is it the receiver that's not playing nice?

Regular ARC has a limit of 1 Mbps. Is your AAC audio bit rate above that limit? Might be transcoding the audio. Can you share your logs with us?

I changed the movie name to myMovie and it's a 4k AAC7.1 movie. It is direct play but the receiver only sees 2 channels.
