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!
