The website requires Microsoft Explorer 9+, Firefox 4+, Chrome or Safari. The site also works on the iPhone and iPad. Smartphones based on Android may not play the sounds. Here are some suggestions to try if the sound doesn't work.
- Check that the computer sound is turned on and working by playing sound from another program or website (e.g. go to BBC iPlayer and try listening to something). If no sound appears from other programs and websites this tutorial gives some common fixes for windows and this page deals with Macs.
- If there is another browser on your computer, try that.
- If your browser is old, update to a newer version.
- If you are using an Android device, use Chrome not the default browser.
