thank you so much , i have successfully installed Flash Player!
but duolingo still tells me this problem "We can't play sound in your browser."
what should i do ??
Do you have any plugins like noscripts, or flashblock? If so you need to whitelist/allow duolingo.com
I have this problem on a pretty regular basis, it seems to be a minor error that goes away after you click on the next problem in an exercise. Give that a try and see if it works. IF not, check for ad blocking/flash blocking stuff.
Often I can just refresh the page and it will stop.
