I don't get a swoosh sound either, nor does Las Vegas slots make any sounds as you play it.

I have my sound settings appropriately set. Been an issue since latest iOS update.

Hi, welcome to iMore.

Make sure the mute switch is not "on". (Pull it up)
Open YouTube, play a random video and turn up the volume to max.
Go to Settings > Sounds & Haptics and disable Change with Buttons.

Now you should be able to hear sounds as before.
