First, please be certain that the volume is turned up and the mute function has not been turned on.
If you’ve been running several apps, there might be a conflict if more than one uses sound. Please close all open apps (including Hooked on Phonics) and re-launch Hooked on Phonics.
Assuming your sound settings are ok, An error with sound may have resulted from an incomplete download. To fix it, please delete the app from your device and re-download it. Your progress will be saved, simply log in again after re-downloading from the For Parents menu. For issues with downloading, see FAQ: The App is taking a long time to download.
