Problems with the sound
The sound in the practices was working fine earlier today but has now cut out entirely. This means I can't complete any more of the exercises as there aren't enough lives to let you complete the section without the purely listening questions.
I looked on the help page and have tried everything they suggested. The sound is definitely working on my laptop and I have tried restarting the computer, the page and the browser. Any one else had this problem and any other suggestions?
