Audio Issue on New Android Tablet

[schwach]

I recently picked up a newer Android tablet, Lenovo Tab M10 Plus (Gen 3), and I'm running into a peculiar issue with my Jellyfin app on it. Whenever I try to play movies, I'm getting partial audio - mainly the background scores, sound effects, etc., but the dialogue or voice lines are barely audible or completely missing.

Things I've tried so far:

• Checked the audio settings within the Jellyfin app itself.
  
• Made sure the tablet's audio settings are not set to any strange modes.
  
• Played the same movie on another device (ipad) and it worked perfectly.
  
• Reinstalled the Jellyfin app.
  
• Switching to the native player does work, so it seems to be related to the web player.
  

Has anyone experienced something similar or can suggest some troubleshooting steps?
Thanks!

Have you tried manually setting the maximum number of audio channels to stereo?

Are these by chance FLAC audio? TDP offers the easiest solution which is trying to force audio transcoding by setting max supported audio channels. I've had mixed success as to whether that actually gets respected (I think maybe device profile overrides whatever you set here?).

I have only ever seen this behavior on 2.X systems (i.e., stereo with or without sub) during playback of media with 5.1+ FLAC audio. No matter what I did, I couldn't get the audio to mix correctly. I ended up re-encoding the audio down to stereo + 5.1 in a non-FLAC format and muxing it back in to replace the original stream. I will never own a surround system where the quality of FLAC matters and I've had a home theater system on the order of $4k before. I don't understand the bloating but that's just me.
