Problem with oscillator/Audio in SoloLearn App (IOS)

Question

https://code.sololearn.com/Wp2MpS0EJoEH/?ref=app

This code works in an editor on my phone and on my computer.
But in the SoloLearn App it doesn't work ...
can someone help me?
I know that it should work, because I can hear the oscillators in other codes.

PS:
I used the search-bar but the one person (that I found) who asked a question on that topic found the solution on their own...

Answer 1

problem solved...
I used a button which starts the oscillators.
maybe it's something with everything needs to load fist pr something else 🤷‍♂️
Hope if somebody has this problem this helps!

Answer 2

I think it is working for me.

When I grab and increase second range input, it actually increases volume.
I don't know if that's how it is supposed to work or not.

Answer 3

for exemple I can hear this code:
