Buffering/playback issues with music

[Samuel Cobb]

What is the best way for me to troubleshoot stuttering, stopping, and otherwise poor playback of music to my Android phones? Latest Windows installation of Jellyfin, Android phones, good wifi, QoSed server, etc...

Not sure how to get diags.

I've tried everything with the Jellyfin Android app. It always messed up on me when the phone went to sleep. I have found a FOSS alternative - Finamp. It plays music fine when it goes to sleep. You may want to try it, it may fix your issue. It's on F-Droid or Github.

Depends on the phone. I was able to get the official app to behave after disabling all the power and data optimizations (Pixel 6a). But some people didn't have luck doing the exact same things I did (I don't recall what phone they had). Can confirm that Finamp is pretty great for music, including offline play. I personally use Symfonium. It isn't free but I do Google surveys so I had some Google bucks to spend.
