A lot of "Listen and type" questions don't have sound. It happened before, but not this frequently. Today almost every other quiz has a sound problem.
I also have this problem. I wondered if it had a connection to what equipment we are using. I am using an ipad mini and contacted support who gave me a link to download Adobe flash player but it says that my ipad mini does not support this. Annoying when half way through a test and you lose hearts.
I think this might be the result of a slower connection, and the audio doesn't have time to download. I've noticed that everything was a bit slower that day, and later when everything started loading faster, there were fever audio problems. If connection is the problem, they could put a button to re-download the audio. It really is frustrating to get everything right and lose a heart because of the audio. But I've noticed this problem in the past week, it never happened before, I don't know if they changed something.
Yes, I've had this happen yesterday and today. I've had to start over because the audio wouldn't play.
It's so weird...it happened to me a bunch of times just now, and nothing on my end has changed. I sent a report about it.
I have had this happen a number of times in various Portuguese lessons. No audio, so I have to type something in the line and then the answer is marked wrong with the translation that I never heard. It's a problem on Duolingo's end. Whenever that happens (can't do it in a timed test, though!), I submit a report. I have submitted A LOT of reports about no audio!
The same problem with me! Something really has to be done by Duolingo. Then again, it is a beta...
I went through all 10 Lessons in Verbs: Present 1 today and didn't find a single problem with audio. Seems it has been fixed. Thank You Duolingo :)
