Problem with photo sound on ios

I have a problem with the sound when taking the photo. I use the 2 photos per second setting and precisely in this setting I do not have sound feedback. In other configurations there is sound, but in this configuration that I use, it doesn’t.

It worked on Android, now that I use iOS it doesn’t work.

What can it be?

Hello, has anyone ever had this problem?

What other configurations are you referring to?

Check the volume on your iOS device. I have had the volume turned down for one reason and forgot to turn it back up when using Litchi.
