Audio background mode (audio) not working..

Audio was playing in the background until recently because I was checking that option off in XCode, but now...

I was advised I was using 'Prepare iOS for recording' and this was the reason my speaker audio was low, but now that I took that out...

Audio will not pay in the background now, but it would with recording enabled.

Thanks in advance.

 

RESOLVED.

FYI..
I used solutions based on info from these 2 people:
aihodge & mbaker ---- Thanks!
(It's an update from an old thread I started, but the solution probably needed to change years later because of Unity updates) https://forum.unity.com/threads/how-do-i-get-the-audio-running-in-background-ios.319602/

SOLUTION:
--------
At the bottom of the startUnity() method I put this code:
---
[[AVAudioSession sharedInstance] setCategory:AVAudioSessionCategoryPlaybackerror:nil];
[[AVAudioSession sharedInstance] setActive: YESerror: nil];
[[UIApplication sharedApplication] beginReceivingRemoteControlEvents];

 

Uhm... I met the same problem, I could not remember how I fixed it but suddenly it was fine after a few days
