Several times in the middle of the lesson, when there's to be a sentence in Spanish for me to write, the voice does not come on. I then cannot go to the previous question but have to start the whole lesson from the beginning. Happened to me twice right now...
don't think it was anything to do with internet connection, more like bug in duolingo. Has happened to me a few times
Happens to me too, It is not related to Internet connection. The voice stopped on one of my computers but works fine on another one. I have sound in any other web page - only duolingo is silent. Any advice?
