iOS ringer status ignored after playing second sound about cordova-plugin-media HOT 1 CLOSED

I've found the issue. Because the situation can hardly be gathered from the Cordova documentation, here are the specifics:

On iOS, you can pass an object to media.play(), with a property called playAudioWhenScreenIsLocked. By default, this property is set to true. Now because the property is passed along with a call to a specific sound object, you may think (like me) that this property will only affect that specific sound. Not so! It's actually setting something globally. And because the property is set to true by default, if you don't set it every single time you play a sound, you'll implicitly be setting it back to true. Despite the name referring to the screen being locked, this property somehow also seems to affect whether there is sound based on the physical ringer switch.

Conclusion: It seems that, if you want the ringer switch to work on iOS, you always need to pass {playAudioWhenScreenIsLocked: false} along every time you use playSound().
