onPlaybackStatusChange doesn't appear to be being called in iOS?

Hi! I'm having an issue with onPlaybackStatusChange. - it isn't called at all.

Steps to reproduce:

1. Clone repo
2. npm install
3. cd example/
4. npm install
5. change capacitor.config to be localhost:5173 (not :3000 - this is misconfigured.)
6. npm run ios, choose simulator device
7. hit "play" - the main audio will play; and it will count up the duration.
8. note that the status does not change; and consequently, the "bicycle" background audio does not play, either

I am not familiar with what play button you are pressing, but onPlaybackStatusChange works for the external controls (pause / play etc) on the device itself), and does NOT emit if you happen to use a code method to pause / play etc.

Is that what you are seeing?

@alexbainbridge Interesting. The example demo implies that both audio tracks (main audio & background audio) should play simultaneously. The actual resulting behaviour is that the background audio never plays, unless external controls are used.

Is the idiomatic approach in this library to have a 'mirror' of the playback status in javascript, which gets updated?

The plugin can play both audio tracks simultaneously. That is one of the main reasons we created it for our app. There is an issue with the example where it only works if you are running in live reload mode as with live reload it is going out to an external server to get the audio vs. locally. I've seen success of playing local files but by passing a file:// or relative path vs. a http path. I just need to update/fix the example 😀

@alexbainbridge is correct in that onPlaybackStatusChange is for updating your UI when external controls are used. You do need to keep track of the status in JS land. I am not sure how else you would do it. You need to have the status in JS so you can change the state of your audio UI buttons (play/pause/stop).

I do think there is value here to fix mention this on the main readme as I hadnt spotted was different android vs ios and @jjgmckenzie hadn't spotted the intent https://github.com/mediagrid/capacitor-native-audio/blob/main/README.md i.e. adjust the documentation at the very least
