[iOS] Unity Player does not respect the "Mute Other Audio Sources" toggle in Player Settings



To reproduce:

1. Download attached project “" 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

- 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

    This is not fixed on 2022.3.13f1. Both on Android and iOS external audio gets stopped when launching the app. The checkbox "mute eyternal audio sources" is unchecked ofc.

    Please fix this for real.

    Faced audio muting other audio sources issues on the iOs platform with version 2018.2 and it was NOT fixed with newer 2018.3.8, as it is mentioned in Unity 2018.3.8 release notes!!! @Unity

    Today I tried every version since 2018.3.14 up to newer 2019.2 and it all still has that bug!

    Interesting, that version 2018.3.0f2 has this bug only partly. Only at the start of the app, it mutes other audio sources but, then you can turn on the music (Spotify or YotubeMusic or PlayMusic) and return to your app.

    Unity doesn't support downgrading to version 2018.2 (where this bug is not present) but wants us to live agong with their bug.

    This bug is present in the latest build.

    I still have this problem. But only at startup of the unity app. In other words background audio is paused when the unity app starts on the device, but you can then switch out of it, resume the audio and switch back in to the unity app without it pausing again.

    Either this is a new bug, or the fix in 2018.3 was only partial. I've submitted a new bug report abut this.

    Can't understand... Korypse wrote Mar 9th that was fixed in 2018.3.8 (indeed, there is a notice in what's new), but the header of the issue says that it was fixed in 2019.2.
    I'm using 2018.3.12 and the problem still exists :-(

    Is anybody here who has it working? What version do you use?
