Sets the [url=https://developer.apple.com/documentation/avfaudio/avaudiosession/categoryoptions/1616611-mixwithothers]mixWithOthers[/url] option for the AVAudioSession on iOS. This will override the mix behavior, if the category is set to [code]Play and Record[/code], [code]Playback[/code], or [code]Multi Route[/code].
[code]Ambient[/code] always has this set per default.
