I have a work around where I have to modify UnityViewControllerBaseiOS.mm to set the AVAudioSession category to SoloAmbient. This is kind of weird since the default setting for apps is already SoloAmbient (if I understand the documentation correctly). Is there someway I can achieve the same setting and avoid modifying files after unity has built the game?
figured it out, just need to set “Override Ipod Music” to true in player settings
