[Help] Jellyfin outputs stereo instead of 5.1 on Zidoo Z9S

[theguymadmax]

Try this:

1. Install Just Player. It's on the Google Play Store.
   
2. In the Jellyfin ATV client, go to Settings-> Playback-> Advanced Playback Preferences, and select Use External Player.
   
3. Play an item, and then choose Just Player as the external player.
   

When you use an external player, Jellyfin will attempt to play the file directly without transcoding.
