Sound problem

When i go to review my vocabulary, the sound doesn’t work but if i go to listen to a lesson it works.

Sorry to hear that. With which language you have that problem? I see that you are studying Spanish and Portuguese, do you have same problem with both?
Which browser are you using?

I often need to click on the button with the mouse, twice even, it doesn’t tend to play automatically and the keyboard shortcut doesn’t work at first.
@zoran: Did you change the TTS? It is barely intelligible at best.
I’m having the problems with all my languages and I’m using Firefox on Windows 10.

the problem is happening with both unfortunately, I’m using google chrome as my browser

sadly it still doesnt work when i click on it multiple times
