[iOS] Unity Player does not respect the "Mute Other Audio Sources" toggle in Player Settings
To reproduce:
1. Download attached project “AudioTest_20183f2.zip" and open in Unity
2. Open “SampleScene” scene
3. Make sure that "Mute Other Audio Sources" setting is unchecked
4. Build the project for iOS
5. Put some background Audio playing (in example Soundcloud playing from Safari)
6. Start the Built project on the Device
Expected results: Background and Built project Audio plays together
Actual results: Background Audio becomes Muted after the Game is opened
Notes:
- This issue does not appear on Android - Mono, and IL2CPP
- This issue appears only on iOS
- Could not check on Unity 2018.3.0a11 because Built project crashes on launch
- Workaround: If the AVAudioSession category is manually set to for example AVAudioSessionCategoryAmbient in native iOS code (tested with [[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryAmbient error: nil]; ), the background audio will continue playing after the app is launched
Tested with:
- iPhone 7 Plus, iOS: 12.0 - Reproduced
- iPhone X, iOS: 11.3.1 - Reproduced
Reproduced on 2018.3.0b1, 2018.3.3f1, 2019.1.0a14 and 2019.2.0a1
Not reproduced on Unity 2018.2.20f1 and 2018.3.0a10
Regression on Unity 2018.3.0b1

As far I have tested it, adding [[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryAmbient error: nil]
does not help at all. (It might help with resuming the app from background, but not when launching the app). There is actually some method called something like InitGraphics / InitRendering I don't really remember which call something internal inside the Unity and is cause of this problem. I don't think there is any possible workaround, only downgrade to older Unity or wait for fix.

I have the very same issue. Where did you put [[AVAudioSession sharedInstance] setCategory: AVAudioSessionCategoryAmbient error: nil]; ? I've tried to put it in UnityAppController.mm both startUnity() and application:didFinishLaunchingWithOptions()

Same thing happened to me.
After updating to the latest Unity 2018.3.2, whenever I open the testing app, the app mutes external sound that comes from Apple Music, which I always listen to.
It turns off the sound coming from bluetooth earphone and iphone speakers.
'Mute Other Audio Sources' is not working.
With Unity 2018.2.x, it was fine.
