FlashCard sound

There seems to be no sound on the FlashCards. How do I turn it on? I have the toggle ON.

There is no sound for flash cards we enter (custom cards), but the there does appear to be sound for those flashcards the Rocket Languages created. They speak when you flip the card.

I think we should request to Rocket Languages that our custom cards should have sound as well, because there are of course more words than they have on the pre-made cards. Because, for example, when I'm learning Russian I need to know how to pronounce. In Spanish it is a bit easier because it is so predictable how it will sound, but this would definitely be worthwhile to set up!
