Stops playing sound when screen locks

[Peter]

Hi,

I just started using Jellyfin but Jellyfin stops playing mp3's when the screen locks.
When playing a mp4, the screen will not lock.

I'm using an Iphone (iOS Version: 17.5.1) and Jellyfin app Version 10.9.6

I've tried the following settings:
- Settings-General-Background App Refresh --> on, Jellyfin itself is not listed.
- Settings-Battery-Low Power Mode --> off.
- Within the Jellyfin app-Settings-Keep Screen Awake --> on.

Tried also to logon via a Web Browser (Safari and Chrome), unfortunately same issue when the screen locks, Jellyfin via browser stops playing.

When Setting-Display & Brightness-Auto-Lock --> never, Jellyfin keeps playing but to preserve the battery it would be great if it is possible to turn the screen off.

Is there any other setting that I missed or is it not possible using an Iphone?

Thank you in advance!

On the Android app, there's a client setting for "background audio" meant for videos, but I assume it also works to allow audio-only files to be played in the background.

Does the iPhone app have that setting? Try enabling it.

Interesting. I have exactly this problem on both an Android and an iOS phone.

@Peter: I don't currently have access to the iOS device because it is being used by a friend. Did the setting resolve the issue for you?

Hi,

No, I cannot find the setting "Background Audio".
I've added a screenshot, hopefully it is visible.

Use Finamp, a dedicated Jellyfin music player. Background playing is not an issue.

Hi @theguymadmax,

I've tried Finamp as well, but I'm unable to connect.

When I populate the Server URL, like this: https://111.222.333.444:8096 and the right username and password:
Error
ClientException with SocketException: Connection refused (OS Error: Connection refused, erno = 61), address = 111.222.333.444, port = 55555, uri=https://111.222.333.444:8096/Users/AuthenticateByName


When I populate the Server URL, like this: https://mydomainname.xxx and the right username and password:
Error
Could not fetch the response for POST https://mydomainname.xxx/Users/ AuthenticateByName.
Status code: 403, error: Error processing request

When I logged on for the first time I got the same error when I tried to connect from my external ip. I'm pretty sure I was using the right credentials. Well about the 4th time it finally connected. Don't know what I did different.

External server:
https://mydomainname.xxx  - correct

Internal server: try using http instead of https
http:// 111.222.333.444:8096

If you aren't using the Finamp beta, consider doing so. It is at a point where it is stable and pretty much feature complete.

But if you want to stick with the official android app, read my post in this thread.

It lists all the settings that you may need to double check in Android to allow for unrestricted battery and data usage in the background.

I tried to login several times without success, same error :-(.

Finally, I thought about the "Maximum number of simultaneous user sessions" (Edit User - Profile - Maximum number of simultaneous user sessions) setting, which was set to 1 and I had already a Jellyfin session open. Increased the "Maximum number of simultaneous user sessions" setting and I was able to login.
Now, when the screen locks or when using another app simultaneously, Finamp (mp3) keeps playing :-).

Thank you all for your suggestions, especially @theguymadmax !

I had my fingers crossed that this would work for me as well but it doesn't seem to have made a difference. I changed my 'Maximum number of simultaneous user sessions' parameter to 10, re-synced my Media files and reset my iOS Jellyfin app completely before re-logging and loading up a song.

My MP3s are still pausing as soon as I minimize the Jellyfin app or lock my phone. Do you think it could be a hardware limitation? I'm using an iPhone SE (2nd Gen) with iOS 18.1.1.
