I would like my app to pause currently playing audio (from other applications) for a certain amount of time, and then resume it. I'm able to simulate the pause/play media key, but the problem is if the system is not playing audio, and then I simulate the key press, it starts playing audio, which is a big no no. So I need to detect if there is audio playing. Some things I have explored: kAudioDevicePropertyDeviceIsRunningSomewhere will detect whether is a device running that can play audio, but that doesn't mean it actually is playing audio. AVAudioSession.isOtherAudioPlaying is exactly what I'm looking for, but I'm not working on a Catalyst app, so it's not available to me. I came across this command, but it is not very accurate. If I pause music, it still returns true for the next 30 seconds or so: if [[ "$(pmset -g | grep ' sleep')" == *"coreaudiod"* ]]; then echo audio is playing; else echo no audio playing; fi Any ideas?

I'm using the sample code provided here: https://developer.apple.com/documentation/swiftui/toolbaritemplacement/keyboard?changes=_8 and the buttons are not appearing above the Keyboard on either iOS or iPadOS. Has anyone else been able to get keyboard toolbar buttons to appear?
