Does anybody else have this problem with Duolingo?
Since a couple of days I'm unable to do the write what you hear exercises because the sound file just won't play. Does anyobody else have this problem? The only recent changes to my system I can think of is installing a Sygate Firewall and uprading to the most recent version of Firefox.
If it happens to me with Opera on Ubuntu, a reload of the page usually resolves the issue.
