How can I repair my sound?
My speech input and my sound doesn`t work and I tried to refresh the page, reopen the browser, re-enable the settings for sound, or reintall my flash. What can I do more for my sound to work?
What OS do you have? What browser are you using?
It would be a good idea to give another browser a try, Chrome is pretty good & comes with its own flash installation, so if the problem is there it might help.
You might also want to right click (or Control click on a mac without right click enabled) on a flash element (like the record button, or the play buttons for sound), and check that the permissions are set correctly to allow DuoLingo to use your microphone & speakers.
