Answer 1

The code you have written is fine, one thing you can do is do not send the sound key val pair if you want to play the default send, as per apple docs if there is no data for sound it will play the default sound.

Answer 2

You can either remove this key/pair value if you want to play one of the default sounds or you can use one of the default sounds available. You can also play one of your own sounds by including the sound file in your app's bundle (check the documentation on which sound files and how to convert them) and then referencing the name of the sound file in the payload.

For example, if you have a custom sound file "cat.caf", you would reference it in the payload.

Tip: To save some bytes on your push notification payload, make the sound files as short as possible, even down to a single letter. Renaming "cat.caf" to c works just fine. Example:

{
    "aps" : {
        "alert" : "You got your emails.",
        "badge" : 9,
        "sound" : "c"
    }
}

This is the available Official documentation.
