Audio Tests don't even play the clip
I do the "Jump a level" tests. I have failed 3 times already because the stupid audio clip doesn't play, and so I can't "translate" if I don't even hear anything.
I can't submit a bug report on the specific question due to it me "skipping" it. I have submitted a general bug report, but Duolingo hasn't gotten back to me yet.
Not solution, but workaround (thanks, @Cloudsurfer7000):
For now, turn off the speakers in settings and you can continue.
are there other similar topics?
